Dark Beast aka Black Beast is a fictional character appearing in American comic books published by Marvel Comics. As an alternate reality version of Beast, he first appeared in issue #1 of X-Men: Alpha in 1995 and was created by Scott Lobdell and Roger Cruz.

In the "Age of Apocalypse" reality, Hank McCoy was a mad scientist and geneticist working for Mister Sinister in his breeding pens, intent on breeding more powerful mutants according to Apocalypse's "survival of the fittest" ideology. Because of Charles Xavier's death and without being taught ethical science while in the X-Men, McCoy became someone ruthless and evil. While Sinister was methodical and rational in his experiments, McCoy found sadistic delight in causing pain to his lab subjects. It was the cruelty of his experiments that caused him to be nicknamed "the Beast", both by prisoners and Sinister's Elite Mutant Force. McCoy also experimented on himself in order to further his mutation, and gained his ape-like bestial appearance. Any mutant that he deemed unworthy was turned into a component of a genetic stew that was used to create Apocalypse's army of Infinites.

Besides being one of the creators of the Infinites, the Dark Beast also experimented on Blink, Jamie Madrox (thus being one of the creators of The Madri), Impossible Man, merged all of the Power siblings into one hideous creature, created Tiger Shark, made Nemesis into Holocaust following his defeat at the hands of Magneto, and was also responsible for the creation of Holocaust's lead hunter Wolverine (not to be confused with the X-Men's Wolverine who was known only as Weapon X in that reality).

With the end of the Age of Apocalypse, the Dark Beast was able to escape into Earth-616 through the M'Kraan Crystal. He was believed to have died due to Quicksilver's interference in his set trajectory. However, the only damage was that he landed twenty years in the past of Earth-616 without any memory whatsoever. He soon met a young Emma Frost, who helped him to regain some of his scattered memories.^[26] The Dark Beast then set base in Manhattan's subway tunnels, and was responsible for the creation of the Morlocks. The characteristics of the experimentation were later recognized by the 616 Mister Sinister as an unauthorized use of his own theories, leading him to order the elimination of the Morlocks. Fearing discovery, the Dark Beast continued his operations in secret. During this time he also trained Marshall Stone III how to control his powers, and set him up as the bounty hunter known as Random.^[27]

The Dark Beast later kidnapped the real Beast and kept him a prisoner behind a brick wall. He infiltrated the X-Men in his place by altering his appearance to match the real McCoy's fur color, although he occasionally found himself at risk of discovery due to Hank possessing a broader range of knowledge than himself, requiring him to bluff his way through some of the questions he was asked.^[28] He helped keep up the ruse by slaying many of Hank's childhood friends and teachers, although he found himself unable to kill Hank's parents. Angered at this emotional weakness, he decapitated a pedestrian as he left town. The Dark Beast was able to keep up his ruse until the Onslaught Saga, during which the Dark Beast joined Onslaught. Onslaught had, in fact, known from the beginning of Dark Beast's ruse and mentally shielded him from other telepaths at the mansion, intending to question him about the reality of his origin. However, upon learning what happened in Dark Beast's reality when mutants ruled, Onslaught decided to destroy both races rather than helping mutants take their place as the world's rulers, only just being defeated thanks to the sacrifice of the Avengers and Fantastic Four.

He also had a few run-ins with Generation X and Gene Nation.^[29][30][31] There he was the leader of the newly revamped Gene Nation, although through the robotic body of Wynter, attempting to capture Generation X to experiment on them. The previous meeting between him and Emma Frost was also revealed. He also led an incarnation of the Brotherhood of Mutants.

Right before House of M, the Dark Beast was in Genosha where he joined Xavier's team after being offered parole. It was confirmed in The 198 Files one-shot that he stayed powered after M-Day.

Dark Beast returns and finally confronts his counterpart in the Endangered Species storyline, where he ambushes him in Neverland, the extermination camp ran by Weapon X, to offer his services regarding finding a cure for M-Day. The two form an uneasy alliance to tackle the impending mutant extinction, but part ways due to their drastically different moral approaches to science.^[32] During a trip to the Guthrie household aimed at requesting samples of DNA from the mother and father of several mutant, and non-mutant, children – the Dark Beast (without warning Henry) poisons one of the un-mutated Guthrie boys, Lewis, in a quick scientific experiment. He then carries the dying boy's body back to the house, suggesting that they should try one of the girls next. Shocked and enraged with his actions, Hank attacks the Dark Beast who, disgusted with Henry's inability to do all that is necessary to save their mutant species, beats him almost unconscious. The fight is interrupted by Mrs. Guthrie, who fires a round from a double-barrelled shotgun into Dark Beast's left shoulder. After scolding Mrs. Guthrie for thinking a round of birdshot would put him down, the Dark Beast is knocked unconscious by Henry.

During the "Dark Reign" story-line, Dark Beast later appears as a member of the Dark X-Men (a team of X-Men put together by Norman Osborn). He serves as the team's scientist.^[33] He constructs a device known as the "Omega Machine" to experiment on mutants in Alcatraz for H.A.M.M.E.R. and starts testing on Beast, causing him great pain and torment as it begins slowly eating him away. Osborn is not impressed with the test results of the Omega Machine and wants Dark Beast to make sure the machine works in removing powers from mutants, not killing them. Dark Beast continues to experiment with his Omega Machine, using Beast as his key test subject. Each use of the device causes Beast to look more decrepit and weak. Deciding to use a new subject to test the device on, Dark Beast goes to collect the newly captured Mindee of the Stepford Cuckoos.^[34] When he reaches the holding cell however, he discovers that Mindee's capture was done to allow X-Force to follow.^[35] Dark Beast is then attacked and stabbed multiple times by both Wolverine and Warpath.^[36]

Dark Beast recovered quickly from his injuries suffered by the hands of Wolverine and Warpath as he was sent by Norman Osborn as well as Mimic, Weapon Omega and Mystique under Jean Grey's form, to investigate the cause of several inhabitants of a small town to dream-walk and continuously repeat "I'm an X-Man". As they investigate, both Mimic and Omega are overwhelmed by some kind of energies and go on a rampage, leaving Mystique and Dark Beast alone with a patient that they were examining. Shortly thereafter the energies takes a humanoid form, and Nate Grey, best known as X-Man, once more takes physical form, much to Dark Beast's shock and horror.^[37]

Dark Beast has since returned to the Morlock's Tunnels after the fall of Norman Osborn. He was able to capture the Lizard and began developing a means of enhancing the Lizard's control of the reptilian parts of the human brain in order to turn human beings into humanoid lizards. Dark Beast had been abducting victims of bullying or abuse from the streets, until the X-Men and Spider-Man found his base. Dark Beast locks Spider-Man out of the room and triggers the mutation in Gambit, Storm, Emma Frost and Wolverine, although Emma comes through the 'attack' unharmed as she is in her diamond form,^[38] giving her and Spider-Man time to escape Dark Beast's minions and release the Lizard to knock him out. Later the X-Men and Spider-Man reverse the process and take Dark Beast into custody.^[39]

While being transported, Dark Beast is approached by the Uncanny X-Force team, who wanted McCoy's help to find a cure for Archangel. As Warren succumbs to the darkness within him, Dark Beast confronted the team with the revelation that the only place left to turn for a cure is the Age of Apocalypse reality.^[40]

They arrived ten years after the X-Men had defeated Mister Sinister, yet it appears that the X-Men still face enormous challenges in this harsh setting. As they follow Dark Beast, unknowingly followed by Wild Child and Sabretooth, to one of his labs, Dark Beast approaches one Gatekeeper, who reveals that no one has ever entered the lab after Dark Beast's disappearance. As they walk in they find a picture with Sinister, Dark Beast, Havok and Cyclops on it, with Dark Beast mistakenly revealing that Prelate Scott Summers is also dead. Dark Beast soon finds the life seed. Nightcrawler then teleports in and swipes the seed away, before he could give it to the X-Force, figuring that Dark Beast was up to some evil plot. After a brief quarrel which ended with the life seed destroyed by Sunfire and Psylocke recognizing Sabretooth from her time on the Exiles, Dark Beast sneaks over to the portal back to the main Marvel Universe, Earth-616, and walks in, leaving X-Force stranded in the Age of Apocalypse world. He then released the now fully evil Dark Angel from his prison and helped him form an army to destroy Earth.^[41]

Following the events of the Dark Angel Saga, Dark Beast has assumed command over the Clan Akkaba of Earth 616 and relocated off world alongside Ozymandias, Famine, War, a pregnant Pestilence, and a badly injured Earth 295 Blob. It also appears he retrieved Sugar Man from Steve Rogers' custody, and together they have rebuilt the dimensional portal technology and returned to the Age of Apocalypse, where the two are using the energies of the life seed to aid Weapon Omega to resurrect a number of fallen mutants in order to provide Weapon Omega an army of powerful mutants.^[42]

At an undisclosed time, Dark Beast leaves the Age of Apocalypse and returns to Earth-616 Universe. He is soon approached by the AoA version of Nightcrawler, who wants to return to their home dimension.^[43] Using the Celestial Dreamer, Dark Beast once again opens a dimensional portal and returns to the Age of Apocalypse along with Nightcrawler. There, he discovers Weapon Omega's defeat at the hands of the human coalition and the capture of the Apocalypse seed. However, returning to the Age of Apocalypse with the X-Men and X-Treme X-Men in tow resulted in the release of evil beings known as the Exterminator which were trapped in the walls between realities by their creators, the Celestials, and destroy anyone they touch.^[44]

In order to defeat these cosmic beings, the X-Men and X-Treme X-men decided to imprisoned them within that reality forever, otherwise, the Exterminators would destroy the whole multiverse.^[45] AoA Nightcrawler teleports them to Earth-616 one at a time and Dark Beast goes with them. Dark Beast arrives on Earth-616 but is knocked out by Gambit. After the Age of Apocalypse reality is closed forever with AoA Nightcrawler's sacrifice, Dark Beast is taken away by the authorities.^[46]

Dark Beast was soon able to escape from the authorities and was revealed to be the mastermind behind the events that lead the Uncanny X-Men and S.H.I.E.L.D. to war. He started hunting the X-Men affiliated with Cyclops by hacking into S.H.I.E.L.D. using classified research sources to upgrade his work and find the X-Men. He was the one to infect Cyclops, Emma Frost, Magik, Magneto and Colossus with nano-sentinels, which is the reason for their broken powers after the incident with the Phoenix Force. Beast finally launches a coordinated attack using a hijacked S.H.I.E.L.D.'s Helicarrier to launch a nuclear strike, and new indestructible sentinels that have adapted to all the X-Men's powers. The only thing he didn't account for was the new X-Man David Bond, aka Hijack, who can control any electronic device. Dark Beast's body has been so weak after experimenting on himself, that he needed a life support suit, so after a short battle his suit was eventually punctured, and he set a bomb that caused his apparent death.^[47]

During the "Last Days" part of the "Secret Wars" story-line, it was mentioned months ago that Dark Beast was among the scientists that Magneto's right-hand person Briar tried to contact in order to make a special cocktail to augment Magneto's powers for the upcoming incursion between Earth-616 and Earth-1610. This occurred sometime before he began suffering from his own genetic experiments.^[48]

During the "Secret Empire" storyline, Dark Beast turns up alive and no longer having health problems. He is shown to have set up a laboratory under an outhouse somewhere in the mutant nation of New Tian following Hydra's takeover. He used this lab to experiment on Inhumans. While searching for an Inhuman named Leer, Quake and the Secret Warriors found Dark Beast's hidden lair. Quake confronted Dark Beast on the whereabouts of Leer, but Dark Beast claimed that he didn't know who Leer was. He continued to profess his ignorance even when tortured by Quake and Karnak. Then a team of New Tian mutants entered the laboratory to remove the Inhumans for intruding into New Tian, and Dark Beast was taken into the mutants' custody.^[49]

Dark Beast's apparent resurrection was later revealed to be Mister Sinister's doing, who saw fit to save Dark Beast's head and attached it to a brand-new body that appeared to be Dark Beast's old self, but with some technological improvements like cannons in his arms and the ability to alter his body at will. He was eventually defeated and held prisoner at Harry's basement.^[50]

Faced with a lack of resources, Cyclops agrees to let Dark Beast work on an "anti-vaccine" to neutralize Callahan's current mutant 'vaccine', with Warlock monitoring the process of creating the cure to ensure that it does only what Dark Beast says, Dark Beast defining it as a simple airborne virus that will feed the mutant vaccine's virus before it can smother the X-Gene, leaving them free to activate. However, after the anti-vaccine has been dispersed worldwide, it is revealed that Dark Beast, with some help from Mister Sinister, had in fact 'tricked' the X-Men as the serum indeed shuts the virus of the mutant vaccine's and is harmless to those who already had their X-Gene activated, but in the presence of a still inactive X-Gene, it works as a catalyst, becoming lethal for potential mutant children. Dark Beast reasoning that this will 'test' humanity's hatred of mutants by putting them in a position where they will risk their children dying to prevent them becoming mutants. As Dark Beast continues mocking them, Magik executes him with her teleportation discs to send part of Dark Beast into the ceiling, killing him.^[51]

During the "Sins of Sinister" storyline, it is revealed that Dark Beast's head was retrieved and secretly kept alive and preserved in a tube by Mister Sinister which he uses for advice. When Dark Beast asks for Mister Sinister to let him out, Mister Sinister informs him that he's not the "darkest beast" anymore.^[52]

• Dark Beast appears as a boss in X-Men Legends II: Rise of Apocalypse. After being captured by Mister Sinister and Apocalypse, Beast is brainwashed and forced to serve them as Dark Beast. While in this state, he believes himself to be one of their followers until he is defeated and cured by the X-Men.
• Dark Beast appears as an alternate skin for Beast in Marvel Future Fight.

The Dark-Crawler, formerly known as the Night-Crawler (unrelated to the X-Men superhero Nightcrawler), which first appeared in Incredible Hulk #126 (1970),^[53] is a large extradimensional humanoid being with a tail. He is originally from a "dark dimension" (not related to Dormammu's dimension). He later becomes master of the Undying Ones' dimension after defeating the Nameless One.

Darter (Randy Vale) is a minor villain in Marvel Comics. The character, created by Bill Mantlo and Jim Mooney, first appeared in Peter Parker, the Spectacular Spider-Man #29 (April 1979).

Randy Vale is an undergraduate at Empire State University. One day, Randy accidentally stumbles across a clone casket that once belonged to Miles Warren. The casket opens to reveal a decayed clone named Carrion. Upon learning of his creator's death, Carrion offers a partnership with Randy to get revenge on Spider-Man. In return Randy is offered power, but it is not specified what exactly the power entails. Randy dons a high tech uniform and goes by the name Darter. As Darter, Randy can glide through the air and fire lasers at his enemies. His first fight is with White Tiger who he manages to knock down. Later, the two fight again in a gymnasium where Spider-Man and Carrion are fighting. When Carrion flees with Spider-Man, Randy realizes that he was betrayed by his master and swears revenge on Carrion. He encounters his master while trying to drain the life from Spider-Man. Randy tries to attack Carrion, but he is hit with the red death causing him to rapidly deteriorate and die.^[54]

When Johnny Blaze learns the truth of his origin, he goes to the prison the Deacon is in to talk to a priest being held there for murder. One of the prison guards lets Deacon out of his cell and gives him two large knives and the stone serum, which gives him super strength. He fights Blaze and is winning until they enter the chapel, where Blaze beats him with a Bible.

Escaping from prison he slaughters the order of nuns that raised Caretaker, known as Sara, and continues to act as an agent of Zadkiel.

Deadbolt is the name of a fictional character appearing in American comic books published by Marvel Comics.

Deadbolt is a mutant and a member of the second incarnation of the Dark Riders which were banded together by Genesis.^[96] Deadbolt appeared to be a living skeleton who could extract his bones and use them as weapons. Deadbolt was decapitated by Wolverine after he rejected the adamantium and regressed to a feral state. His disembodied head was then used to lure Gauntlet into Wolverine's grasp.^[97] Deadbolt, along with several of his fellow Dark Riders, was resurrected by means of the Transmode Virus to serve as part of Selene's army of deceased mutants. Under the control of Selene and Eli Bard, he took part in the assault on the mutant nation of Utopia.^[98]

The Demon Bear is a character appearing in New Mutants and X-Force connected to Danielle Moonstar and the formation of the New Mutants. Its powers include teleportation, super strength, shapeshifting, negative emotion empowerment, and corruption of human souls.

As a child, Danielle Moonstar unintentionally used her emergent psychic powers to foresee the deaths of her parents, William and Peg Moonstar, in a vision that showed them being slain by a bear. When the couple disappeared on a hunting trip a week later, Dani believed her vision had come true.^[99] It was later revealed, however, that Dani's vision had been metaphorical; in truth, her parents had been captured and transformed into a demonic bear spirit.^[100] The identity of the being responsible for this transformation was never revealed in story, but the letters page of The New Mutants #24 would state that it was the ancient mystical entity the Adversary.^[101]

In the early days of her time as a member of the New Mutants, as depicted in The New Mutants #3, Dani experienced a vision of the Demon Bear. Initially, she believed it was simply a nightmare, born of the childhood fear that the bear which had killed her parents would one day come to kill her too, but when she attacked the bear with her hunting knife, she drew blood and realized that the bear was both real, and no mere animal.^[102] Increasingly troubled by her dreams of the Demon Bear, Danielle Moonstar ran various Danger Room scenarios against bears and then confronted the demon alone; it mauled her and severely damaged her spine.^[103] The New Mutants rushed her to the Mid-County Medical Center. The Demon Bear infiltrated the hospital, transported the team to the Badlands, and turned nurse Sharon Friedlander and officer Tom Corsi into demonic Native American warriors under his control. They later reverted to normal humans but still kept the appearance of Native Americans. Here, the New Mutants fought and defeated the Demon Bear, disrupting it with Magik's Soulsword. Danielle's parents leaped from its body, returning them to normal.^[104]

X-Force member Warpath encountered a Demon Bear of his own while on his way to visit his brother Thunderbird's grave and would have been killed were it not for the intervention of Ghost Rider who offered his assistance against the demon. Defeating this bear, they discovered it was the corrupted form of the Apaches' animal spirits, who had been driven mad by Eli Bard, who used a dagger full of black magic to do so.^[105]

The Demon Bear later appears in possession of Bishop, before being driven out by Psylocke.^[106] Once Bishop is freed, Psylocke takes on the now docile bear as a companion.^[107]

Demon Bear appears in The New Mutants.^[108] This version was manifested by Danielle Moonstar after her mutant powers first activated and subsequently destroyed the reservation that she lived on. In the present, Moonstar summons the Demon Bear again after Cecilia Reyes attempts to kill her. Subsequently, she battles the bear in her mind and dissipates it after confronting her past.

Death Metal is a fictional robot appearing in Marvel Comics. The character appears in the Marvel UK imprint. He first appeared in Death³ #1 and was created by Dan Abnett and Dell Barras.

Death Metal was created by Doctor Evelyn Necker as part of the Minion project which also produced Death's Head II and Death Wreck. Necker sends Death Wreck through space and time, and he comes back with a magical semi-living metal that she calls "Promethium". Necker uses this metal to create a new cyborg, but she is unaware that the Promethium was created by the evil being called Charnel.^[114] Death Metal later steals a time machine and flees to the parallel universe of Charnel.

There he is found by the alternate versions of several mainstream Marvel Universe supervillains, whom he kills, and several alternate versions of several superheroes, whom he tries to kill. However, Death's Head and Death Wreck also arrive in Charnel's universe and end up fighting Death Metal along with the heroes. When that universe's Ghost Rider uses his mystical Penance Stare on Death Metal, it causes him to see his own sins and realize the extent of Charnel's evil. The three cyborgs then team up and defeat Charnel. Death Metal is then thrown through a temporal warp to modern-day Earth. After going on a disoriented violent rampage in Toronto, he encounters a being called Argon, a warrior of pure spirit who has been sent from another dimension to end the threat of Death Metal. He absorbs Argon's mind and spirit, only to find that his purity counteracts Death Metal's violent rage. Now seeing himself as a monster, he begins to seek his own death.

When the superhero team Alpha Flight arrives in response to his rampage, he attempts to escalate the fight so that he might be killed. Unfortunately, this only restores his berserker rage, until Aurora uses her light powers to calm him. Realizing he is still a danger to others, he teleports away (see Death Metal #2 and Death Metal vs Genetix #1). In Death Metal vs. Genetix, Death Metal seeks to create a being that can destroy him. He takes cell samples from Alpha Flight's Madison Jeffries and Genetix's Vesper (both of whom can control technology) and creates an embryo which he surgically implants in empath Krista Marwan. Genetix rescues Krista, who inexplicably vows to have the child.

The first Death-Stalker was Philip Wallace Sterling. An enemy of Daredevil, he first appeared as the Exterminator in Daredevil #39 (April 1968), and as Death-Stalker in Daredevil #113 (September 1974).

Created by	(the Exterminator) Stan Lee, Gene Colan; (Death-Stalker), Steve Gerber, Bob Brown
In-story information
Alter ego	Philip Wallace Sterling
Team affiliations	Unholy Three
Notable aliases	the Exterminator, Death's-Head II
Abilities	Interdimensional travel Death-grip gloves grant ability to kill a person upon contact

Philip Wallace Sterling was born in Riverdale, Bronx, New York. He was a wealthy man prior to embarking on a career as a professional criminal. When he first appears as the Exterminator, he recruits the Unholy Three. He constructs a "time displacer ray" ("t-ray") which can teleport its target into another dimension (possibly the Limbo from which Immortus hails). The Exterminator leads the Unholy Three in a series of criminal activities and battles Daredevil. When Daredevil defeats the Exterminator and his agents, he also destroys the t-ray, accidentally bombarding the Exterminator with its strange energy and seemingly killing him.^[115]

Sterling finds himself trapped between two dimensions, able to return to Earth at will but only for a few hours at a time; furthermore, the mutation causes his skin to become chalk-white. He steals a pair of gloves from A.I.M. that give him a death-grip, and begins calling himself Death-Stalker.^[116] He tries several times to kill Daredevil and build a new t-ray machine, but most of his battles with Daredevil end in a draw.

He is allied with the Gladiator against Daredevil. Death-Stalker travels to the Florida Everglades in search of papers relating to Ted Sallis' experiments and encounters the Man-Thing.^[117] He later steals a set of ancient Lemurian mirror lenses from various museums and uses them to create a powerful gun to destroy Daredevil. However, Daredevil destroys the gun, and in the midst of their battle, Death-Stalker is mysteriously discorporated by the Sky-Walker.^[118] He reappears in a third costumed guise as the second Death's Head, gifting an enforcer called the Smasher with superhuman strength and kidnapping Karen Page to force her to give him the original Death's Head's research. He is defeated by Daredevil and Ghost Rider, killing the Smasher with his touch during the battle.^[119]

Sterling resumes the Death-Stalker identity and assembles a large gathering of criminals to take part in an undisclosed theft, presumably of t-ray components. Daredevil finds out about the gathering, and in the resulting confrontation Death-Stalker touches (and thus kills) one of his underlings, frightening the others away. Seeing no point in battling Daredevil at this time, he teleports away.^[120] Angered at this latest interference with his plans, he creates another Smasher and sends him to kill Daredevil. The new Smasher fails and Daredevil refuses to imprison him, knowing that Death-Stalker would enter the prison and kill him for his failure.^[121] Turning to a new plan, he steals a newly developed scientific apparatus from Stark International.^[122]

Death-Stalker attempts to kill Daredevil while the crime-fighter is hospitalized, but is stopped by the Avengers.^[123] He creates a new Unholy Three and has them kidnap Matt Murdock, whose secret identity as Daredevil he learned by observation from between dimensions. Daredevil is taken to St. Stephens Cemetery, where Death-Stalker kills two of the Unholy Three and attacks Daredevil. Unable to overcome Death-Stalker's superior abilities, Daredevil knocks out the nearby street light, thus enclosing the cemetery in darkness. Fighting blindly, Death-Stalker rematerializes while his body is phasing through a tombstone, which kills him instantly.^[124]

Death-Stalker is, for a brief time, survived by his mother, Elizabeth Dawes Sterling. Lying on her deathbed, and in her hatred for Daredevil for the death of her son, she has her house converted into a deathtrap and builds child-like androids fitted with self-destruct devices constructed to lure him to his demise. Daredevil just barely manages to escape her deadly revenge, and she dies before Daredevil can be lured into the trap.^[125]

A new female Death-Stalker appeared in the first issue of Villains for Hire (the villain counterpart of Heroes for Hire). This Death-Stalker's true identity is unknown. She is among the villains hired by Purple Man to help him start his new criminal empire. Death-Stalker is almost shot in the head by Crossbones and shrugs to him, stating "you can't kill what is already dead." Death-Stalker later survives an explosion of the boat she is on.^[126]

Death-Stalker normally exists in another dimension, where he can observe events without being detected. He can return to Earth for a limited period of time, with his dimensional abilities allowing him to become invisible and intangible and travel vast distances instantaneously.

Death-Stalker also wields "cybernetic death-grip" gloves that enable him to emit deadly radiation, and is a skilled criminal mastermind and scientist.^[117]

Death Wreck is a fictional cyborg created by Craig Houston and Stewart "Staz" Johnson, first appearing in Death Wreck #1 (January 1994). Death Wreck is a prototype built by A.I.M. scientist Evelyn Necker in 2018 as part of the Minion project. Constructed at short notice and considered entirely expendable, Death Wreck contains the "brain of a wino" housed within a body powered by a car engine.

Death's Head 3.0
Publication information
Publisher	Marvel Comics
First appearance	Amazing Fantasy vol. 2 #16 (December 2005)
Created by	Simon Furman James Raiz

The third version of Death's Head was introduced in 2005, the result of an online poll on the Marvel Comics website.^[127] Fans were given the chance to choose between four existing Marvel characters: Death's Head, Woodgod, Wundarr the Aquarian, and the Texas Twister. The winning character was to be revamped and receive their own storyline in Marvel's Amazing Fantasy vol. 2 title. Death's Head won, receiving 49% of the vote.^[127]

Death's Head creator Simon Furman stated that he contacted Marvel as soon as he became aware of the poll.^[128] Amazing Fantasy vol. 2 editor Mark Paniccia had already intended to contact Furman to ask him some questions about the character,^[127] and their conversation also led to Furman writing the initial Death's Head 3.0 story. The character's look was that of one of the Reaver cyborgs from the Incredible Hulk storyline Planet Hulk.^[129]

The initial Death's Head 3.0 story also included a number of elements that tied it into previous Amazing Fantasy vol. 2 stories. Death's Head's sentience and power source come from A.I.M.'s attempts to first capture and then replicate the power that created Captain Universe. Issue #16 reveals the scientist that began the project was Monica Rappaccini, the mother of the new Scorpion, on the back of her attempts to capture the Uni-Power in other titles. Varina Goddard is revealed via A.I.M. records to be Monica's granddaughter.^[130] Furman says he has "mixed feelings" about the story, as he likes it but feels that this is not Death's Head: "I always thought it strange that poll was to bring back one character and what readers got was another entirely... I'd have much rather done the original."^[129]

While the Minion project is mentioned as the reason for Death's Head being given his name, no other ties to the previous Death's Heads were included. However, Simon Furman has stated that he would "work in a little retroactive back story to create a kind of unified Death's Head-verse" if the character was revived in the future at some point^[128] and it has come out that he had originally intended to imply Death's Head 3.0 was the original, in an early form,^[131] which the warlock Lupex would abduct and turn into Death's Head's body. Marvel rejected the idea, however.^[129] In Nova #17, Dan Abnett and Andy Lanning did their own version, depicting the Minion project as being originally based on a Death's Head "3.0" cyborg.^[132]

The third version of Death's Head debuted in a five-part storyline within the pages of Marvel's anthology series Amazing Fantasy vol. 2, beginning in #16 (Dec 2005). Written by Death's Head creator Simon Furman and drawn by James Raiz, the story is set 100 years in the future and does not appear to be directly linked to the previous Death's Head stories.

A.I.M. are set to make peace with the UN and become a legitimate non-terrorist organisation. Hardliner A.I.M. Senior Scientist Patricia Goddard has decided to stop the peace treaty and force A.I.M. back underground by assassinating the UN Secretary-General, using a mysterious alien cyborg in A.I.M.'s possession code-named Death's Head. Powered and given intelligence by an artificial variant of the Uni-Power, the cyborg is sent out into the field with preprogrammed objectives, but the clash between its murderous inclinations and an instinctive desire to help people leave it unsure on which side it wants to be.

The final panel of the Death's Head 3.0 story concludes with an image of the cyborg with mouth horns, alluding to the original Death's Head.^[133] Comic artist Simon Williams has said that Furman was going to end the story by having the character say "I'm Death's Head, yes?", to establish that Death's Head 3.0 was an early version of the original, but the "yes?" was cut off by the editor by mistake.^[131]

Mechanoids with the same design as this incarnation of Death's Head went on to appear on Sakaar, during the Planet Hulk series,^[134] and are used by the Hulk as soldiers during the World War Hulk event.^[135] One is used as an A.I.M. courier by Monica Rappaccini in the five-issue miniseries Super-Villain Team-Up: MODOK's 11.^[136] It is shown during Nova's Secret Invasion issues that the Hulk's Death's Head units have been handed over to Project P.E.G.A.S.U.S. for study by a Dr. Necker under her "Minion" Project. After Norman Osborn's H.A.M.M.E.R. forces come in to shut the facility down, it is revealed that Dr. Necker is an A.I.M. double agent, explaining how Death's Head was in A.I.M. possession during the Death's Head 3.0 miniseries.

More recently, during the Enigma Force tie-in miniseries of the Incredible Hulks: Dark Son story arc, it is revealed that this model of Death's Head was built in the Microverse during a war with K'ai thousands of years ago. Sometime after the war, some of the warships they were aboard were sucked through the Great Portal of Sakaar, which is said to breach time and space.

Dr. Paxton Page is a character who is a scientist who perfects the cobalt bomb. He later goes mad and fakes his own kidnapping and death so that he can assume the guise of the supervillain Death's-Head. He dresses in a glowing radioactive costume, riding a horse whose flesh is made transparent, and wields fireballs and scimitars of radioactive cobalt. Page's daughter Karen returns to her parents' home to investigate her father's disappearance, and Daredevil follows her. In the ensuing battle between Daredevil and Death's-Head, Death's-Head spills a vat of molten cobalt over Daredevil, but realizes that Karen is endangered. This brings him back to his senses, and he pushes Daredevil and Karen to safety. He appears to die in this act of self-sacrifice when he is covered in the molten cobalt.^[137]

Deathurge is a character who is a former servant of Maelstrom.

December (Winter Frost) is a mutant in X-Nation 2099. In the year 2099, Frost gets a job at a local amusement park. However, it is not a typical park, and has a king and queen who preside over it. One day Queen Perigrine disappears, and they find her body at the bottom of the Tunnel of Love. After that day, King Avian begins to be suspicious of everyone and requires genetic scans of all incoming tourists before they can enter. Anyone with genetic anomalies is imprisoned in an underground labyrinth and subjected to many tests and acts of torture. Frost is discovered to be a mutant and is imprisoned like the others. She is capable of drastically lowering the air temperature surrounding her hands and projecting it outwards to freeze the air around her into arctic gale winds, allowing her to flash freeze or freeze dry objects in her surroundings.

Johnny Dee (John D.) is a fictional mutant character who debuts in Son of M #1 (2005). Johnny has an octopus-like creature that protrudes from his chest with several tentacles. The creature has a brain of its own but cannot speak (although, it is suggested in The 198 that the latter could be false^{[volume & issue needed]}), and can produce a voodoo doll of a person after Johnny puts a sample of their DNA (like a strand of hair) in its mouth. The creature spits out a clamshell that contains a tiny naked replica of the person, giving him the ability to control the person entirely. Johnny and the creature share the same nervous system, but Johnny cannot feel the creature's pain. This is evidenced in Son of M #1 when one of the creature's tentacles is slashed, leaving them both on the verge of death, but Johnny is oblivious to the actual extent of the injury.

Johnny is one of the few mutants who keeps his powers after Scarlet Witch's alteration of the world to remove the powers of the world's mutants. Living in Mutant Town, Johnny is about to be killed by mutant-hating thugs.^[138] After being rescued by Spider-Man, Johnny agrees to move to the Xavier Institute for his own safety. There, he becomes part of The 198.^{[volume & issue needed]}

When Magma arrives at the school, they share a conversation about her recent outburst. Magma sees him as a friend, but Johnny begins falling in love with her. Magma admits that Johnny looks cute but is a bit disgusted by his powers. Later, Johnny appears to use his powers to create small duplicates of Magma,^[139] and later of Jazz as well. They appear to be voodoo dolls that make the targets come under Johnny's control. Jazz spies on Johnny and finds him making a voodoo doll of Jazz. Johnny later uses the doll against Jazz and kills him.^[140]

Later, Demetrius Lazer has Johnny kill Mr. M.^[141] Johnny continues to be a pawn in General Lazer's agenda, until Lazer is found out by Val Cooper and General Reyes. Lazer and Johnny are incarcerated, but while Lazer is being tortured by Cooper for information to unlock a door trapping most of the 198, he realizes that Johnny touched him, at which point Johnny snaps the neck of a voodoo doll of Lazer, killing him. At this point, Johnny remains behind bars.^[142]

Father Delgado preaches at the Holy Ghost Church, which is located in the slums of Hell's Kitchen. He arrives at his church one day to find Cloak and Dagger, who came seeking sanctuary. After hearing their story, he chooses to honor their wishes of being discreet and feeds and houses them. He even defends them from the police, leading away police detective Brigid O'Reilly.^[143] Delgado's church acts as their superhero base, and he aids other superheroes like Spider-Man and the New Mutants.^[144] Later, Delgado accompanies Cloak and Dagger to visit Dagger's mother, Melissa Bowen. When she turns out to be cruel and uncaring, Dagger blights her and returns to Cloak and Delgado.^[145] Delgado is shown to detest Cloak and Dagger's vigilante efforts, but cannot stand to see them leave, particularly Dagger as he wants to "rescue" her from Cloak's "demonic" life.^[146] The duo, along with the newly transformed Brigid, who has become Mayhem, rescue Delgado from criminals who were posing as a religious group.^[147]

While thankful for being rescued, Delgado still fears that Cloak and Dagger's souls were corrupted by demons. Both the congregation and Daimon Hellstrom refuse to perform an exorcism for him, so he attempts to do so himself. He is stopped by Mayhem who ridicules him for his selfishness. Ashamed, Delgado prays.^[148] When Dagger returns to the church, Delgado confronts Cloak and forces him to leave with holy water. His action inadvertently awakens the Predator, the demon responsible for Cloak's hunger, and resurrects the spirit of Jack the Ripper. When Dagger learns that Delgado turned Cloak away, she angrily leaves him. Delgado is later taken away to a psychiatric hospital by the congregation.^[149] He is placed in a padded cell and tells Mayhem that he has lost his faith.^[150] Dagger later visits Delgado and learns that he appears to be sane; however, it is quickly revealed that he is under the control of Mister Jip, who is keeping him alive and who he sees as his God. He is visited by Dagger's uncle, Michael Bowen, who has replaced Delgado at the Holy Ghost Church. As the two pray together, Delgado secretly prays to Mister Jip and plots to kill Dagger, who he views as a temptress.^[151]

Feeling that this is part of a test by Mister Jip, Delgado lets slip where Dagger is. Thinking he has failed, Disciplinarian enters, looking for Ecstasy. Delgado tries to fight him off, but is shot.^[154] He recuperates in the hospital, but is convinced that he has failed the Lord due to Cloak and Dagger being together again. Dagger visits him and as she is thanking him for his bravery in protecting her, he continues to plot to kill her.^[155] He is eventually released and reports to Mister Jip about Cloak and Dagger. Mister Jip breaks his promise to Delgado and takes over his body, effectively killing him.^[156]

Doctor Demonicus (Douglas Birely) is a supervillain appearing in Marvel Comics. He possesses advanced knowledge of genetic engineering and clashes with the Avengers and the Shogun Warriors, in addition to S.H.I.E.L.D.

Doctor Demonicus first appeared in Godzilla, King of the Monsters vol. 1 #4 (Nov 1977) and was created by Doug Moench and Tom Sutton.^[177]

Douglas Birely was born in Culver City, California. As a scientist, he was studying the correlation between radioactivity and mutation when he was contaminated by a radioactive spill. As Doctor Demonicus, he is a criminal geneticist. His discovery of the Lifestone radioactive meteorite allows him to create immense kaiju-style monsters mutated from animals. These include Batragon, Ghilaron, Lepirax, and Centipor. Using his monsters and his Demon-Soldiers, he raids oil tankers from his secret laboratory located on one of the Aleutian Islands. The monsters are defeated by Godzilla and Demonicus is defeated by Gabe Jones and taken into S.H.I.E.L.D. custody. When Jones confronts Demonicus, he is willing to tell Jones his background, and when referencing his monstrous creations says "Knowing of his nuclear radiation mutation, I took my cues from Godzilla himself". When Godzilla begins slaying the creatures he has made, Demonicus becomes unstable, even claiming he would battle Godzilla directly in order to save one of the creatures.^[178]

Demonicus becomes an ally of the Myndai alien Maur-Konn, who gives Demonicus his gigantic space satellite base orbiting the Moon. Demonicus later uses his genetic and robotic monsters — the Starchild, Cerberus, and the Hand of Five — against the Shogun Warriors Raydeen, Combatra, and Dangard Ace. Demonicus launches a meteor strike against Earth from his base on the dark side of the Moon. He is defeated by the Shogun Warriors and taken into custody by S.H.I.E.L.D. again.^[179]

He eventually captures, mentally controls, and further mutates Godzilla (however, the creature is deliberately not named as such, because Marvel's license to use the monster had, by that point, expired. To give readers a clue as to who the creature was, Demonicus refers to the creature as being both "the greatest living dinosaur" and "my once-greatest enemy", the latter referring to Godzilla's defeat of his original creations). The creature also, for unknown reasons, shrinks in size once Demonicus captures and enslaves him. He sets Godzilla against the West Coast Avengers, and also salvages Iron Man's original armor and uses it to attack the West Coast Avengers personally. He is defeated by Tony Stark,^[180] and is later mutated by both the Lifestone and the demon Raksasa. His alter ego develops skin cancer, which is kept under control by devices in his costume.

Demonicus is the founder, creator, and leader of the Pacific Overlords, who gained their various superpowers due to Demonicus exposing them to fragments of the Lifestone, and with them battles Sunfire and the West Coast Avengers. He raises a land mass from the Pacific Ocean floor just north of Hawaii, and founds on it the new nation of Demonica with himself as ruler. He attempts, unsuccessfully, to get the United Nations to recognize Demonica as a sovereign nation.^[181] Demonicus is seemingly killed when Demonica sinks back into the Pacific.^[182]

Doctor Demonicus is eventually arrested, tried, convicted, and incarcerated for his crimes. He is sentenced to the Raft, a supervillain prison facility. He is among the 43 villains who escape during a breakout engineered by Electro.^[183] The Hood hires him as part of his criminal organization to take advantage of the split in the superhero community caused by the Superhuman Registration Act. He helps them fight the New Avengers, but is taken down by Doctor Strange.^[184] Demonicus participates in the Hood's temporary alliance with superheroes in order to battle an invading Skrull force.^[185] As seen in flashbacks, the Hood used his powers to help Demonicus and the others escape from jail. During a secretive gathering, Demonicus and the others learn of the Skrulls' attempt to infiltrate and control their organization.^[186] He joins with the Hood's gang in an attack on the New Avengers, who were expecting the Dark Avengers instead.^[187]

Doctor Demonicus is a genius with a PhD in genetics and has an advanced knowledge of genetics and the advanced technology of the alien Myndai. He wears a costume that contains life-support devices that keep his skin cancer in remission. He has demonic-looking features, including mottled skin and horns on his forehead. He carries a blaster that fires an unknown form of concussive energy. He uses advanced genetics, robotics, and force field technology adapted to various weaponry. Doctor Demonicus possesses the Lifestone, a radioactive meteor, with which he has created artificially mutated monsters and humans.

Dragon Man is a fictional character appearing in American comic books published by Marvel Comics.

Dragon Man is an android built by Professor Gregson Gilbert of Empire State University as an experiment. Gregson hoped to find a way to bring it to life. He could not find a way to do this until the alchemist Diablo arrived and brought it to life under his partial control using his supernatural powers.^[190] However, Dragon Man broke his control and attempted to kill Diablo.^[191][192] Although Dragon Man is slow-minded to the point that he is incapable of speech, he understands orders given by Diablo and is a determined foe of the Fantastic Four (although the creature has always displayed a King Kong-like affection towards Sue Richards). Dragon Man is not especially malicious, although he is easily manipulated and provoked to violence.

Dragon Man later died, was revived, encountered Medusa and Gorgon, and fought the Thing and Human Torch.^[193] After his death, Dragon Man was later studied by Hank Pym at his laboratory. He was restored to life again by Diablo and was defeated by Pym as Goliath and escaped.^[194] Dragon Man battled Hercules and the Avengers destroyed Diablo's army of Dragon Men.^[195] Dragon Man was once found by the original X-Men and was made to be an unofficial mascot of sorts. After a period of time on the team where he developed a deep affection for Jean Grey, Dragon Man had to be released to the creature-filled island known in the Marvel Universe as Monster Island.

Dragon Man was reclaimed by Professor Gregson Gilbert and sent by Lemuel Dorcas to attack Namor.^[196] He was next used by Gregory Gideon to attack the Fantastic Four.^[197] Dragon Man was then sent by Machinesmith to attack Captain America.^[198] He later became the mount for the extra-dimensional dragon rider Ral Dorn.^[199] Dragon Man then fought Hulk and Kate Waynesboro when it was under the control of Ringmaster and the Circus of Crime.^[200]

Dragon Man encountered the child superheroes called Power Pack. Gregson Gilbert later attempted to replicate the creation of the Dragon Man without the addition of alchemical interruptions, and this time succeeded. He created a number of androids based on other legendary creatures. These androids were defeated by Power Pack, and Gilbert and Dragon Man go to work at Disneyland.^[201] Dragon Man was used as a servant of Aron the Rogue Watcher.^[202] He faced Spider-Man during the Acts of Vengeance, when he was unleashed on him by Wizard.^[203]

In addition to his servitude to Diablo, Dragon Man has served Super-Adaptoid and was also a member of the New Enforcers. In The Spectacular Spider-Man #235–236, Roxxon Oil sprung him from a government containment facility to capture and dissect him to create robotic super-soldiers based on Dragon Man's powers. He was freed by Ben Reilly. Dragon Man later showed up in Africa under the influence of mad scientist Eric Pain.^[204] Though the creature was under a full rage, he ended up defeated once more by both superheroes. Afterwards, he resurfaced in Beyond!, destroying an Avengers Quinjet the group was using to escape.

During the Civil War storyline,^[205] he was spotted at the funeral of Stilt-Man. After poisoning the guests, the Punisher blew up the bar in which the wake had been held. He was later seen being arrested by S.H.I.E.L.D. agents.^[206] Alyosha Kraven later began collecting a zoo of animal-themed superhumans,^[207] including Bushmaster, Gargoyle, Tiger Shark, Kangaroo, Aragorn, Vulture, Mongoose, Man-Bull, Swarm, Mandrill, Grizzly, Frog-Man, and Rhino. In the end, the Punisher managed to sabotage this zoo; though Kraven himself escaped to the Savage Land. In Avengers: The Initiative #8, Dragon Man had been captured by the trainee heroes, having been attracted to Komodo. In Nova, Dragon Man was seen battling the newly revived Nova Corps consisting of Qubit, Fraktur, Tracel, Morrow, Irani, and Robbie Rider. He was subdued by the Corps using a gravimetric net.^[208]

At one point, Dragon Man had been placed in the Negative Zone, and like most of the other prisoners, was conscripted into service when Blastaar attacked the prison. When the Shadow Initiative was sent in to liberate the prison, Blastaar sent Dragon Man against them. However, Komodo was able to use Dragon Man's attraction to her to convince him to switch sides.^[209] Following this, Dragon seemingly reforms, as he, Artie and Leech were seen at Franklin Richards' birthday party.^[210]

Dragon Man has since been upgraded by Valeria Richards and joined Reed Richards' Future Foundation.^[211] Valeria used her talents to upgrade Dragon Man to have super-intellect and have the power of human speech. Dragon Man would become an adopted member of the Future Foundation and guardian of the gifted children in that program.^[212] As part of the Marvel NOW! event, Dragon Man created the Thing Rings for Darla Deering to wear, which enables her to become Miss Thing.^[213]

Frank Drake is a direct descendant of Count Dracula (via a marriage from before he became a vampire). The character first appeared in Tomb of Dracula #1 and was created by Gene Colan and Gerry Conway.^[219]

Frank Drake is a former millionaire who had squandered his inheritance and had nothing more than an ancestral castle in Transylvania. Planning to sell it, he and his friends travel to the castle, and discover Dracula's skeleton. They accidentally resurrect him, and Drake narrowly escapes death. Drake eventually relocates to London.^[237]

Broke and in despair, Drake attempts to commit suicide but was saved by Rachel van Helsing and Taj Nital, two vampire hunters.^[238] The two, along with Quincy Harker, were dedicated to killing Dracula and his vampiric followers. Drake joins the group under van Helsing and Harker's tutelage.^[239] Drake soon encounters Blade,^[240] with whom Drake constantly clashed but would eventually befriend. Later, Drake and Brother Voodoo battle zombies sent by Dracula.^[241] Drake, Blade, Van Helsing, Harker, and Harold H. Harold help Dracula battle Doctor Sun.^[242]

Quincy Harker eventually made the ultimate sacrifice by detonating a bomb concealed in his wheelchair which destroyed him, Dracula, and much of the castle in which they met for the last time. Drake and Van Helsing discovered Harker's wheelchair, and the supposed death of Dracula.^[243] Quincy's final letter to Rachel and Frank urged the two of them to grow closer together and discover what they all knew was there all the time. As a result, Frank and Rachel attempted a romance but due to Frank's later account, Rachel was an empty shell without Dracula to fight. The two shortly parted but not without deep regrets. Rachel would eventually be turned into a vampire herself and died mercifully at the hands of X-Man Wolverine.^[244]

After hearing of Dracula's return, Drake and teams up with Blade, Hannibal King, and Doctor Strange to defeat him.

In their first appearance, Doctor Strange helped them battle the Darkholders.^[246]

Drake, wishing for a more normal life, eventually left the firm. Apparently, the friendship between King, Drake, and Blade had soured. Drake moved to Washington, D.C., and married Marlene McKenna. During this time, Marlene seemed to come under the power of Dracula and scarred her face to resemble Rachel's facial scars. Drake, Blade and Katinka eventually aborted Dracula's resurrection again. This resulted in Blade's nervous breakdown and institutionalization.

With the weakening of the Montesi spell, Dr. Strange realized that not only were vampires returning, but also that there was an increased occurrence of supernatural invasions. On this realization, Strange arranged for the release of Blade and for Drake to meet him and King back at their old Borderline offices. Together, they formed the Nightstalkers; by day, they are private investigators, by night, they fight any number of supernatural villains.^{[volume & issue needed]} Drake, armed with an anti-supernatural nanotech gun named Linda (after Linda Blair of The Exorcist) fights alongside Blade and King against various occult enemies.^{[volume & issue needed]}

Odessa Drake is a supervillain and thief who first appeared in The Amazing Spider-Man vol. 5 #8. She was created by Nick Spencer and Humberto Ramos.

Odessa Drake was raised in New York City by her father, Castillo, as a member of a secret society of criminals known as the Thieves' Guild.

She became leader of the Thieves' Guild, which she sought to return to glory by killing anyone on debt with the Guild and stealing gear from superheroes. Fellow Guild member Black Cat was worried over the consequences stealing from superheroes would have on the world, so she contacted Spider-Man and the two tried to give back the stolen items. Odessa and the Guild attempted to stop them by fording them into the magic-powered vault where they kept the stolen items, but had to retreat when Spider-Man used Ms. Marvel's phone to contact reinforcements. Odessa was nevertheless pleased that the Guild has risen in infamy through their actions.

In the aftermath of the King in Black storyline, Black Cat revealed to Drake that her father Black Fox has stolen the Thieves' Guild's immortality by surrendering New York's deed to the Saint. Under the agreement of getting rid of the Black Fox, Odessa agreed to help Black Cat, and the two traveled to the Saint's world, where they convinced the Saint that Black Fox was going to scam him, so he brought Fox to his world as punishment. Later, the two discussed the possibility of a relationship in spite of their positions in the Guild, before having sex together.

Through the following months, she would refuse to help Black Cat's mother after being diagnosed with cancer due to not wanting to bend more Guild rules for her sake, and helped Black Cat escape from Nick Fury Jr.

The Dreaming Celestial (Tiamut the Communicator) is a Celestial that first appeared in The Eternals #18 (December 1977). Created by Jack Kirby, his origins were added in stories written by others and published decades later. Within the context of the stories, the Dreaming Celestial is a renegade Celestial named Tiamut. He claims that during the Second Host to visit Earth, he resisted the Host's decision to not turn the Earth over to the Horde and was exiled and his spirit trapped in the "Vial".^[257] This remains sealed under the Diablo Range in California until it is discovered by Ghaur, who temporarily releases the Dreaming Celestial's power.^[258] He is reawakened by the Deviants and acts as a beacon for the Horde as he proceeds to "judge" Earth.^[259] This leads to his confrontation with Fulcrum and his ascending from the state of being a Celestial.^[260]

Tiamut the Communicator's function was to alert the Fulcrum of the findings of the Celestials during planetary examinations and to send a signal to the Horde to collect the planet's aggregate life-force. He was one of the ten members of the First Celestial Host when it visited Earth one million years ago. During this visit, Tiamut personally created the Eternal Makkari, designing him for speed and with several other interesting features in his DNA structure. It is said by some that the Deviant conqueror known as Lord Tantalus from the planet Arqa was created more than 25,000 years ago by the Dreaming Celestial but this has not been confirmed.

During the Second Celestial Host, the Deviants were the dominant force on Earth, and Tiamut was ready to call the Horde to begin the harvesting of the planet. However, Arishem had that order canceled, and had many of the Deviants culled, while not touching the other species. As this was a violation of their protocol, Tiamut deemed Arishem to be malfunctioning and tried to assume command by attacking Arishem. Although Tiamut defeated Arishem, he was then attacked by four other Celestials who had been working with Arishem, and he was imprisoned underneath the mountains. Why they did this though, is still not truly clear, and mention must be made of the fact that this account of events was given by the Dreaming Celestial itself and has not yet been rebutted or verified. It should also be noted that, by giving this account to Makkari, the Dreaming Celestial contradicted his account.

One of the Exterminators killed the Dreaming Celestial during their attempt to invade the Multiverse.

Tiamut the Communicator possesses the power of cosmic energy control with an unknown upper limit. His armour is able to easily withstand strikes from nuclear warheads and planetary impacts. Tiamut seems to be one of the most powerful Celestials as Galactus feared it and Uatu the Watcher could not see anything when it awoke.

• Tiamut appears in Eternals (2014), voiced by Alex Zahara.^[261]

• Tiamut appears in the Marvel Cinematic Universe (MCU) film Eternals (2021). This version is an unborn Celestial residing in the Earth's core, who would destroy the planet after his birth. The Eternals are initially tasked with aiding in Tiamut's birth, but turn against the Celestials to stop him after learning the truth. After Tiamut partially emerges from the Indian Ocean, the Eternals form the Uni-Mind to petrify him, leaving only his head and left hand.^[262]

Sgt. Michael "Mike" Duffy is a fictional character in Marvel Comics. The character, created by Joe Simon and Jack Kirby, first appeared in Captain America Comics #1 (March 1941).

Michael Duffy was the superior of Steve Rogers and James Barnes who were secretly Captain America and Bucky. He had a short temper and was always getting after his soldiers for "goldbricking". He was always picking on Rogers and Barnes for not being heroes, an ironic claim as he was unaware of their dual identities. He had nearly put two and two together, but would later deny the possibility.^[273] At one point, Duffy showed remorse when he thought that Rogers and Barnes had died in a Japanese air raid, only to go back to berating them when he found out they were alive.^[274] He also had a crush on Betsy Ross^[275] though this was retconned to show that he had a lover overseas named Flo.^[276] While out on a mission, Duffy and several soldiers were caught in an explosion. He survived and was recuperating in a hospital. Due to his lack of appearances afterwards, it's implied that he stayed in bed for the remainder of the war.^[277] Years later, Rogers would visit Arlington National Cemetery to see his former commander's grave stone and reminisce on old times.^[278]

Michael Duffy appears in the Marvel Cinematic Universe films Captain America: The First Avenger and Captain America: The Winter Soldier, portrayed by Damon J. Driver.^{[citation needed]} This version is a drill sergeant who is not comically temperamental nor mean-spirited towards Steve Rogers.

Fred Duncan was an agent with the FBI. Along with fellow agent Bolivar Trask, Duncan was asked by his superiors on how to handle the "mutant threat". While Trask felt that America should fear them, Duncan thought it was best to work alongside them. Duncan's idea was approved, causing tension between him and Trask to the point that the latter suspected him to be a mutant as well.^[279] He then teamed up with Wolverine to battle Lyle Doome who went by the name Virus.^[280]

He met with Professor Charles Xavier and became the FBI's federal liaison with the X-Men. He was then provided a special headband so that he can communicate with Xavier whenever it was necessary. He helped Xavier with the eventual recruitment of Scott Summers.^[281] As a member of the Xavier Underground, a network of mutant supporters, Duncan maintained mutant criminal records and stockpiled weapons and technology from X-Men foes.^[282]

Duncan later helped the X-Men once again when the team had to break into the Pentagon to delete the files they had about their identities.^[283] Henry Peter Gyrich suspected that Duncan had something to do with the files being deleted and demanded that he somehow get them back (the Department of Mutant Affairs answered to Gyrich's Project Wideawake), but Duncan instead resigned. Duncan then decided to write a tell-all book about his time working with the mutants.^[284] After Duncan's death, Carl Denti, an aspiring agent, takes the files, weapons, and technology for himself and assumes the name X-Cutioner, with the proclaimed mission of killing any mutant that has killed other people first.^[285]
