M-11 is a fictional character appearing in American comic books published by Marvel Comics.

Originally known as the Human Robot, the character was named "M-11" in the 2006 to 2007 Agents of Atlas miniseries as an allusion to its first appearance in Menace #11 from Atlas Comics (Marvel Comics' 1950s predecessor). In an alternate reality from mainstream Earth, a scientist's newly created robot is programmed by the scientist's greedy business manager to murder the scientist. The incomplete robot, however, continues through with his directive to "kill the man in the room", and kills the business manager when the man enters. The robot then leaves the house, programmed to "kill the man in the room" but ultimately falls off a pier into the sea and short-circuits.

Jason Philip Macendale Jr. () is a fictional character appearing in American comic books published by Marvel Comics. The character first appears in Machine Man #19 (Feb. 1981), created by writer Tom DeFalco and artist Steve Ditko. From 1987 to 1997, Macendale initially wielded only the Hobgoblin identity and weaponry but the 1988–89 Inferno crossover writer Gerry Conway had Macendale imbued with demonic powers by N'astirh. In addition to power over hellfire and increased strength and speed to far greater than the original Hobgoblin, these powers also disfigure Macendale so that his head is even more grotesque than the Hobgoblin mask, and ultimately alters his mind so that he was deluded into thinking that his appearance is normal. Macendale eventually succeeds in purging himself of his demonic powers and was later revamped again with cybernetic implants.

Mad Jim Jaspers 
Sir James "Mad Jim" Jaspers is a character in American comic books seen in Marvel Comics. He was created by David Thorpe and Alan Davis for Marvel UK. He is a powerful supervillain who was the archenemy of Captain Britain and Excalibur as well as a few other heroes as well as the main antagonist of the Excalibur series.

In the reality of Earth-238, James Jaspers, a British politician waged a political war on mutants. He had been elected into office as a member of the English Parliament because of his anti mutant and anti super heroes stance and politics, however Jaspers was a mutant himself with powerful reality-warping abilities. His political façade and motivations for the elimination of his fellow mutants and superheroes was essentially to ensure his supremacy. Jaspers seemed a gifted politician and adapt at swaying popular public opinion, with lines such as "if they were honest they wouldn't wear masks" but whether he was always mad, or descended into madness with the advent of his mutant reality warping powers, Jaspers had lost his sanity. Jaspers of Earth-238 was so determined to rid his world of mutants, he began to move beyond drumming up anti-mutant sentiment and constructed an incredibly powerful adaptive cybernetic construct known simply as the Fury to hunt and eliminate all superpowered beings.

Jaspers had also formed an advanced technological equipped military task force charged with eliminating super powered beings, this group known as the Status Crew. Typically the Status Crew would round up powered beings to be held in concentration camps with their extermination there not long after. The Fury would deal with bigger threats. It would take less than two years for super powered beings to be on the verge of extinction. The Fury had been programmed by Jaspers to allow Jaspers to live as the sole powered being.

Unmatched in power by any other being, any potential threats ruthlessly destroyed by the Fury, Jaspers adopted the persona of Mad Jim Jaspers, a bank robber and crook paying homage to the Mad Hatter from Alice in Wonderland as well as continuing the Lewis Carroll book theme with his own bank robbing crew, the Crazy Gang. It was around this time that the Omniversal Guardian Merlyn aware of not just this reality's version of Jaspers danger to the multiverse, but the Jim Jaspers of the 616 reality who Merlyn realized possessed even greater reality warping power. Merlyn would teleport one of the few remaining super heroes of Earth-238, Captain UK Linda McQuillan, to the 616 designated reality. Importantly he would also do so whilst she was being observed by the deadly cybiote the Fury. The Earth of 238 would fall into disarray due to the mad machinations and reality warping of Jaspers. It had become known as a crooked earth. Of similar concern was that the Jaspers of 616 had begun his political ascension, a worrying sign of things to come.

Upon returning to mainstream reality/616, Captain Britain found that another Sir James Jaspers was leading an anti-superhero campaign, with the aid of Henry Peter Gyrich and Sebastian Shaw, members of the Hellfire Club.

Jaspers managed to win a landslide general election victory on his anti-superhero platform and became Prime Minister of Britain. Events began to mirror those of Earth-238 and Jaspers unleashed the force of the Jaspers Warp upon London, causing much chaos and devastation. However, Jaspers found himself under attack from the reality-hopping Fury, and the two engage in a large-scale reality-warping battle in which Jaspers was ultimately killed by the Fury, who teleported him outside the universe, where he would have no reality to control and thus be rendered powerless.

When X-Factor splits their wards between two boarding schools, Artie attends St. Simons. During the Inferno, Artie is abducted by the demon N'Astirh. Before he is rescued, Artie witnesses at least two murders.

Artie loses his mutant powers after "M-Day". Artie moves to the Baxter Building where he gets a special helmet made by Valeria Richards. It allows him to communicate by creating images in the air – he remains mute due to the deformity caused by his mutations. Joining Artie is his long time friend Leech. Later, the original Fantastic Four leave our reality for what they assume to be four minutes. Weeks pass instead. This possibility had been planned for and the Foundation children are watched over by a trusted roster of replacement members.

Magique 

Magique, originally known as Magic, is a Shi'ar warrior and member of the Imperial Guard. The character, created by Chris Claremont and Dave Cockrum, first appeared in The Uncanny X-Men #107 (October 1977). Magique has the ability to create realistic illusions. Like many original members of the Imperial Guard, Magique is the analog of a character from DC Comics' Legion of Super-Heroes: in her case Princess Projectra.

Along with Gladiator, Mentor, and Quasar (later known as Neutron), Magic was one of the founding members of the Imperial Guard, brought together centuries earlier by T'korr, Majestor of the Shi'ar Empire, for the purpose of stopping Rook'shir, who has been driven insane by the malevolent force known as the Dark Phoenix, and was laying waste to the galaxy.

Magic and the Guard first clash with the X-Men and Starjammers, on behalf of D'Ken and Davan Shakari, over the fate of the Shi'ar Princess Lilandra Neramani. After the battle, Lilandra takes over as Majestrix, and the Guard swears allegiance to her.

After Lilandra's sister Deathbird stages a coup and becomes the new Shi'ar Empress, the Guard comes into conflict with a rogue Space Knight named Pulsar (not the Imperial Guard member Impulse, who later changes his name to Pulsar) and an alien named Tyreseus. After a large conflict which also involves Rom and other Space Knights — which leads to the deaths four Guardsman — Pulsar and Tyreseus are defeated.

Some time later, Empress Deathbird sends the Imperial Guard to Earth to battle the combined forces of the Starjammers and the superhero team Excalibur, so that she can claim the power of the Phoenix Force for herself. The Guard are forced to retreat when Deathbird realizes the Starjammers are led by Lilandra. (Some time later War Skrulls impersonating Charles Xavier and the Starjammers depose Deathbird and restore Lilandra to the throne. Deathbird cedes the empire back to Lilandra as she has grown bored of the bureaucracy.)

Now named Magique, the character takes part in "Operation: Galactic Storm," which details an intergalactic war between the Shi'ar and the Kree. Magique and the Imperial Guard steal the original Captain Marvel's Nega-Bands from the dead hero's tomb. Using Kree artifacts, including the Bands, the Sh'iar create a massive super weapon, the "Nega-Bomb." Ultimately, the Nega-Bomb device is successfully detonated, devastating the Kree Empire, with billions dying instantaneously (98% of the Kree population). The Shi'ar annex the remnants of the Kree Empire, with Deathbird becoming viceroy of the Kree territories.

At the beginning of the "War of Kings" event, Magique is part of the Imperial Guard faction that attacks Ronan the Accuser on his wedding day. The Guard also slaughters many new Nova Corps recruits. Magique leads a squad of Imperial Guards to Knowhere, base of the Guardians, tracking Adam Warlock. However, Adam has begun turning into his dark counterpart, the Magus, and tricks Magique's troops into killing her.

Some years later, she is replaced by a member of the Subguardians in Guardians of the Galaxy (vol. 5) #1.

Maha Yogi is a fictional character in the Marvel Universe. He first appeared in Journey into Mystery #96 (September 1963), and was created by Stan Lee and Jack Kirby.

Yogi was apparently born 10,000 years ago in what is now Central Europe. He apparently was a savage that came to possess some portion of the same Bloodgem that Ulysses Bloodstone would later possess, which gave him immortality and eternal youth. He later came to Britain during the time of Camelot, and impersonated the real Merlin while he was away. The Eternal Sersi exposed the impostor, and the real Merlin placed him in suspended animation.

The false Merlin was revived in modern times, still posing as Merlin, and battled and was defeated by Thor, after which he went back into the coffin. He later became a professional criminal and took the name Warlock, organizing a band of armored mercenaries. He abducted Marvel Girl, battled the original X-Men, and was rendered comatose by Professor X.

Later, as the mentalist Maha Yogi, he attempted to create an army of mind-slaves. He fought and was defeated by the Beast and Iceman. The Maha Yogi then became the chairman of Merlin Industries. With Mongu, the Maha Yogi plotted world conquest, but was defeated by the Hulk and Doctor Druid. During his encounter with the Hulk, his fragment of the Bloodgem was destroyed and he rapidly aged into helplessness. Some time later, the Maha Yogi was revealed to have been created by the Caretakers of Arcturus and to have turned against them. He later appeared alive with his youth apparently restored by unknown means.

As a result of mutation induced by the Caretakers of Arcturus, the Maha Yogi had the psionic abilities to control the minds of others, create illusions, project psionic force bolts, levitate objects as large as a building, teleport himself, create force fields and alter his own appearance. His psionic powers have a limited range.

Thanks to his possession of a fragment of the Bloodstone, the Maha Yogi is virtually immortal, and has a physically malleable body.

He has attempted to use true magic, performing a ritual to summon the demon known as Grendel's Mother.

She was with the Guard when they come into conflict with a rogue Space Knight named Pulsar and an alien named Tyreseus. After a large battle which also involved Rom and other Space Knights — which led to the deaths of four new Guardsman — Pulsar and Tyreseus were defeated.

Later, when Deathbird became Empress, Astra commanded the entire Imperial Guard, including Manta, to fight the combined forces of the Starjammers and Excalibur on Earth so that she could claim the power of the Phoenix Force for herself. The Guard were forced to retreat when Deathbird was put in danger. Some time later War Skrulls impersonating Charles Xavier and the Starjammers depose Deathbird and restored Lilandra Neramani to the throne. Deathbird ceded the empire back to Lilandra as she had grown bored of the bureaucracy.

Manta was again part of the Imperial Guard missions "Operation: Galactic Storm" and "Starblast."

Later during New X-Men, she fought the X-Men under the manipulation of Cassandra Nova. In the latter, Manta sought out Jean Grey, confident she could defeat Phoenix while armed with psychic armor, but Grey easily bested her in hand-to-hand combat.

Manta was one of the survivors of the battle with Vulcan. She had many further adventures with the Imperial Guard, in such storylines as "Secret Invasion," "X-Men: Kingbreaker," "War of Kings," "Realm of Kings," the "Infinity" crossover, the "Trial of Jean Grey," "Time Runs Out," and the return of Thanos.

Martin Burns 
Martin Burns is the 1940s Marvel Boy. After a mysterious shadow revealed to him that he possessed the power of Hercules, he became a superhero. The character made only two appearances: Daring Mystery Comics #6 (June 1940), by the writer-artist collaborators Joe Simon and Jack Kirby, and USA Comics #7 (February 1943), by writer-artist Bob Oksner. Each featured a wildly disparate version of his origin, with the first positing him as the reincarnation of the mythic Greek demigod, while the second had him accidentally scratched by Hercules' mummified remains in a museum and "infected' with his superhuman strength, although both versions shared the basics noted above. The Official Handbook of the Marvel Universe: Golden Age 2004 reconciles these different origins by stating that there were two Marvel Boys named Martin Burns active in the 1940s.

Master Izo 

Master Izo is a fictional character appearing in American comic books published by Marvel Comics. A superhero martial artist, he is associated with Daredevil, and first appeared in Daredevil vol. 2 #112. He was created by Ed Brubaker and Michael Lark.

The man who would be known in the modern age only as Master Izo was a member of the organization The Hand hundreds of years ago in Feudal Japan. Following the death of its founder, Kagenobu Yoshioka, and its transformation from a samurai alliance into a ninja cult in service to a demon, Izo chose to leave. At this time he put out his eyes, which enabled him to see the world, he claimed, as Yoshioka had (and as Daredevil later would).

Izo would later found The Chaste, a rival martial arts association situated atop a sheer cliff known as the Wall. However, his unhindered nature eventually led his students to vote him out, disgusted with his drinking and gambling. Stick took his place as the leader of the Chaste. Izo was revealed to have been present shortly after the accident which gave Matt Murdock his superhuman senses, and reported this information anonymously to Stick. Later still, he became the trainer of the future supervillain and Hand assassin Lady Bullseye, who he promised would one day become the Hand's leader. He is mentioned a number of times in the Book of the Iron Fist.

Much later, following the death of the Skrull posing as Hand leader Elektra, Izo journeyed to New York City, where the four remaining ninja-lords of the Hand were assembling to forcibly induct Daredevil as the new leader. Izo intervened to assist Daredevil in driving them off, which led them to switch their focus to the Kingpin. Izo's purpose was in fact to manoeuvre Daredevil into taking the position, as a means of reforming the Hand away from its corrupted state. He was also revealed to have placed Black Tarantula within the Hand as a mole, unbeknownst to Daredevil. Ultimately, Daredevil accepted the position, and ordered that the Kingpin and Lady Bullseye be banished. Her erstwhile ally's treachery exposed, Lady Bullseye vowed to kill Izo, who told her to "get in line." Subsequently, Izo fakes his own murder at the hands of Daredevil to trick the Hand into accepting Daredevil as their leader. He later shows up in Shadowland to reveal to the heroes involved in the battle against Daredevil and the Hand to explain his discovery that Matt Murdock had been possessed by the Beast.

Master Izo is a formidable martial artist, one of the finest anywhere in the world, including being able to wield two katana at once. He has considerable stamina, enabling him to traverse the city by jumping on rooftops. Despite (or rather, as a result of) being blind, he has superhuman-radar senses, much as Daredevil does. He also evidently possesses some form of immortality or at least life-extending capability, as he is now somewhere in the area of 500 years old.

Match 

Match (Ben Hamill) is a fictional character appearing in comic books published by Marvel Comics. A mutant, Hamill attended the Xavier Institute before its closing. While at the institute, Hamill was the field leader of the Paragons training squad.

Publication history
The character, created by Nunzio DeFilippis and Christina Weir, first appeared in New Mutants Vol. 2 #7. DeFilippis revealed that while he and Weir created the character, he was based on a background mutant from New X-Men: Academy X, #7. "We saw a cool bit of artwork in the background of a panel (I think it was Carlo Barberi who first drew him) and thought for a few seconds about a name, codename, and power set."

Fictional character biography
While spending time in his home town park, Ben Hamill suddenly manifested his mutant powers. Unable to control his powers, Ben set flame to the town's park.

After the manifestation of his powers, Ben was enrolled in the Xavier School for Gifted Youngsters. While at the school, he chose the codename Match, where he was present at Xavier's special assembly head by the headmaster Charles Xavier to inform the student body of an explosion that happened the night before caused by Magma who'd been awoken from a coma by Josh and Julian's involvement. Xavier preached about heroism being more than being brave. Match would later attend Parent's Week at Xavier's, although it is unknown if his parents for the week he seem to enjoy himself during the festive time. While in class with Karma, he was asked along with his classmates if they'd seen Josh, who was unknowingly out on a date with Rahne Sinclair.

After enrolling at the institute, Hamill was assigned to the Paragons training squad under the tutelage of Rahne Sinclair. Though hot-tempered (even voted "Shortest Temper"), Hamill is a natural leader, and consequently, was named as the field leader for his squad. As a part of the field squads games, the Paragons participated in a Danger Room session where they had to fight a Hulk construct. After the exercise, the New Mutants squad tried the same simulation and beat the record set by the Paragons' exercise. During a team meeting with Rahne, Ben and his teammates expressed their dismay at the New Mutants squad having had beat their time. Rahne then gave them a much needed a pep talk, trying to remind them that they would have save a lot of lives if the session had been real. Soon after, Cyclops and Emma Frost revealed that Sinclair had been in a romantic relationship with a student, Josh Foley, who was abruptly departed from the school, leaving the Paragons without an advisor. Ultimately, former New Mutant Magma stepped in to become the Paragons' mentor.

Ben is still viewed as such by his former teammates after the dissolution of the squad system. Following the events of House of M, only 27 of the school's students retained their powers. All squads were dissolved, and the remaining students were merged into one group. Ben and his fellow former Paragons Trance, Wolf Cub, and Pixie were revealed to be among the handful of still-powered Xavier students.

Match, along with several of his fellow students, is sucked down into the realm of Limbo. When attacked by demons, he quickly joins the fight, killing several demons while trying to protect Pixie and Blindfold. Ben participates in the final fight against Belasco and is returned to the school after Belasco is defeated.

Ben relocates to San Francisco along with the other X-Men. He reappears putting out fires started by rioting over Proposition X, an anti-mutant reproductive legislation being pushed by the anti-mutant organization "Humanity Now!" After the riots subside, the Dark X-Men along with Norman Osborn declare a citywide curfew for all citizens prohibiting public activity after dark. In Avalanche's bar, Match, along with fellow student Hellion and other mutants angrily decide to cause a scene after curfew hours for all the world to see as a warning against the "fascism" of the Dark X-Men. As Match spreads fire throughout Union Square, the Dark X-Men come to arrest the troublemaking mutants. After a battle, they are taken into custody by the Dark X-Men. Eventually, Match and the other imprisoned mutants are freed by the X-Force and teleported to the island of Utopia.

Ben's abilities are pyrokinesis, enabling him to produce and manipulate flame. In addition, he is seemingly immune to fire and high temperatures. As a side effect of his powers, Ben's head remains constantly aflame, though it appears that he can control the extent of the flaming; during a Danger Room session, he is able to maintain some level of stealth by lowering the intensity of his head flame.  Ben's body is always glowing, and emits heat, however it is not hot enough to burn his clothing. The flame on his head is also not as hot as normal fire and as such, it does not burn what it touches. This was confirmed by his creators, Nunzio DeFilippis and Christina Weir.

Match makes a cameo appearance in Dark Phoenix, portrayed by Lamar Johnson.

She at first wanted to bring the pair to justice, but she eventually learned to trust the young crime-fighters. Later, she took a squad of police officers to investigate a warehouse belonging to the same pharmaceutical company that was behind Cloak's and Dagger's powers. Some corrupt policemen, led by Roger Falcone, exposed the other police officers to a gas to asphyxiate them. With her dying breath, Brigid swore vengeance on Falcone. As Brigid lay dying, Cloak and Dagger found her, and though were too late to save the other police, Cloak surrounded her and Dagger with darkness, while Dagger tried to revive her with light. When this appeared not to work, the pair abandoned her body to search for those responsible.

Though O'Reilly died, she was reborn as Mayhem. In this new form, Mayhem helped Cloak and Dagger find and fight the corrupt police. She then killed Falcone as promised. She then became a vigilante, showing no mercy to the drug dealers and other criminals she pursues. Mayhem was considered as a "potential recruit" for the Initiative program, according to Civil War: Battle Damage Report.

Mayhem exudes a green, venomous gas from her pores. If this gas enters another person's bloodstream, it paralyzes the person for a varying amount of time. Mayhem attacks people by raking their skin with her talon-like fingernails so that the gas will enter their bloodstreams. The gas can also act like a truth serum, forcing a victim of Mayhem to tell her the truth. Dagger's "light-knives" dissipate upon contact with this gas. Mayhem can levitate herself and fly.

Menace 
Menace (Lily Hollister) is a fictional character, a villainess appearing in American comic books published by Marvel Comics. The character is most commonly depicted as an enemy of Spider-Man. Her first appearance as Lily Hollister is in The Amazing Spider-Man #545, and her first appearance as Menace is in The Amazing Spider-Man #550 which is the start of the second story arc in the "Brand New Day" overarching storyline that followed the events of "One More Day".

Daughter of District Attorney William "Bill" Hollister, socialite Lily Hollister was dating Harry Osborn. Lily found a hidden door in Harry Osborn's closet and found an old journal of his. She uncovered the location of one of Norman Osborn's secret rooms in the journal. When she had first gone in, she found all of the Goblin's equipment along with some experiments. After accidentally knocking over some experimental Goblin chemicals, she absorbed them into her skin, and was now able to transform into her "Menace" form at will. Stealing a weapons cache of the original Green Goblin, Norman Osborn, Menace was later hunted down by Jackpot. During her search, she met Spider-Man and reluctantly accepted his help. Menace attacked a council meeting and kidnapped councilwoman Lisa Parfrey, with Spider-Man and Jackpot working together to try and stop her. Menace's glider slammed into the rescued councilwoman, killing her, and Menace escaped the crime scene, but not before accusing Spider-Man of being responsible for the woman's death.

Menace later tried to threaten Bill Hollister, her father and one of the candidates for the election, into dropping out of the race for mayor while she continued supporting him in her public identity. She was sabotaging his campaign for his own good against Randall Crowne, his opponent, and began destroying her fathers advertisements. She also broke into their home and tried to threaten him into backing out of the running. Menace then proceeded to threaten the supposedly 'redeemed' Norman Osborn who had come to town when her actions inadvertently revealed that Crowne had been operating an illegal sweatshop in the city and Crowne asked him for help. Menace recreated Osborn's original death by ramming him with her glider, however, Osborn survived the attack and Menace spared him, after accusing Osborn of being a fool for devoting all his time and assets to Spider-Man's destruction. During the Skrull Invasion, Lily and Harry Osborn were attacked on the street, after getting away from Harry and changing into Menace she killed one of the invading Skrulls, and then set her sights on Jackpot, believing her to be "Spider-Man's girlfriend". Their fight took her into the path of one of the Skrulls, with Menace's glider exploding on contact. Menace survived, though badly injured, and limped away from the scene.

When Menace attacked a Hollister Rally, she managed to badly beat Spider-Man (who had earlier been shot through the arm) and claimed a "citizen's arrest" to the arriving police. Menace then flew into the Hollister party headquarters, and changed back into Lily Hollister, just before Harry walked in on her. She revealed to Harry that she was Menace. She then told Harry that she accepted his earlier marriage proposal. On Election Day, Menace attacked two police officers for arresting her former friend Carlie Cooper for a crime she didn't commit, then attacked Spider-Man when he appeared. Menace was about to finish him until Harry, as the Green Goblin, appeared and shot Menace with a serum, with Spider-Man giving her the full injection. This caused Menace to change back into Lily and was seen in a live broadcast, with her father watching in shock and in tears of this revelation. A few days after the event, with Bill Hollister as the new Mayor of New York, Lily was now in prison and was visited by Norman Osborn, who discovered the engagement ring given to her by Harry and welcomed her to the family.

She is later seen released from prison and approaches Harry in her Menace form, telling him that she's "moved on". Harry believes that she has started a relationship with Norman and warns her that she will be disposed of once Norman's done with her.

During the Dark Reign storyline, Lily reappears in her Menace form to Harry Osborn in The Amazing Spider-Man #595 threatening Harry's life at first, but then showing Harry that she is pregnant. After this, Harry calls Norman Osborn to inform him that he will be accepting his invitation to work for the Dark Avengers, which highly upsets Peter Parker. Harry's real reason for joining is to steal a cure for the serum to use on Lily and the baby so they can be healthy.

However, she pushes him away and reveals that it was all a ruse to make Harry become American Son so he could be used to die in a tragedy to engender sympathy and support for Norman. She also shows a new goblin form, with a decidedly more feminine figure, large full horns, and a green complexion. Lily reveals to Harry that Norman is actually the father of the baby. She then goes to work for Norman's Dark Avengers in an unknown capacity. After Norman's fall from power, Lily is on the run from the law. It is also revealed that, due to the time of conception, there is a possibility that Harry is the father of her unborn child.

In the "Origin of Species" storyline, Lily crashes into Harry Osborn's coffee shop and gives birth to a baby boy. Then a group of supervillains, hired by Doctor Octopus, attack her and kidnap the baby. Spider-Man manages to rescue the baby, but he is stolen again by Lizard. Spider-Man manages to track him down, only to have the Lizard willingly give the baby back to Spider-Man because his tests to determine paternity prove that Norman is not the father. Word of her child's safety (but not the paternity) gets back to Lily, who is relieved. She runs away because she feels she is unfit to raise the child. Spider-Man later tests Harry's blood, revealing that he is in fact the father, and leaves the child in his care.

As part of the Marvel NOW! event, Menace returns showing her allegiance to the Goblin King as part of his underground Goblin Nation when it comes to preparing for the fight against Superior Spider-Man (Doctor Octopus' mind in Spider-Man's body). Menace is ordered to disarm the prison truck that captured Phil Urich (the former Hobgoblin) before taking him to the underground and christening him as the Goblin Knight.

Menace later kidnaps Carlie Cooper from Potter's Field after she finds that Doctor Octopus' grave is empty and brings her to the Goblin King. Menace then gives the Goblin King the journal revealing the secret about Superior Spider-Man. During the Green Goblin's takeover of Manhattan, the real Spider-Man returns and defeats the Goblin Nation. In the process, he uses an antidote for the Goblin Serum on Menace, turning her back to a normal human.

During the AXIS storyline, Phil Urich tries to free Lily Hollister from police custody, blowing up the police car in which she was being transferred. She survives, but is rendered amnesiac and becomes the heroine Queen Cat under Roderick Kingsley.

Midnight's Fire 

Midnight's Fire is a fictional supervillain appearing in American comic books published by Marvel Comics. He first appeared in The New Warriors #2 (Aug. 1990), and was created by Fabian Nicieza and Mark Bagley. Midnight's Fire is a mutant.  His powers and his sister Silhouette's powers are derived from their ability to tap into the extradimensional energy of the Universal Wellspring, due to being descendants of the Dragon's Breath Cult which had based their cult around the base of one of the wells for centuries.

In 1966 during the Vietnam War, an American recon patrol in Cambodia stumbled upon the ancient, hidden temple of a cult known as the Dragon's Breath, which had remained hidden for centuries. It had been built upon a well-spring of raw, primal energy called the "Well of All Things". The inhabitants decided to breed a superior race that would one day unite with the ways of the west. They believed that this union would produce children capable of harnessing the power of the Well. The members of the recon patrol were to be the fathers of these children, one of these men was Andrew Chord the man who would become Midnight Fire's and Silhouette's father.

Midnight's Fire and his sister Silhouette are the only children of Andrew Chord, former guardian of Dwayne Taylor (Night Thrasher) and his wife Miyami (daughter of Tai). Silhouette, Midnight's Fire and Dwayne began an organized effort to take down various New York City street gangs, but their partnership ended when Silhouette was shot and paralyzed from the waist down. Midnight's Fire blamed Dwayne and became a cop killer and a druglord to lure Dwayne into a physical confrontation he could not possibly win.

Diego Cassias, one of the other members of the recon patrol now calling himself the Left Hand, stole the power of the Well from his own child, then gathered the other children of the pact including Midnight's Fire into a group called the Folding Circle. The Circle attempted to take control of the Well away from Tai. Members of the Circle, together with the New Warriors, managed to defeat Tai, but the Well was sealed, Cassias and Tai were apparently killed, and the surviving members of the Circle escaped in a stolen Avenger's Quinjet. The remaining members of the Folding Circle later crashed in Madripoor and attempted to usurp the role of local druglord, which was then held by Aardwolf, a Mutant crimelord. They succeeded, but were later taken down by Night Thrasher and Silhouette.

Midnight's Fire returned in the newest volume of 'New Warriors'. He has a face to face meeting with Night Thrasher, whom he still believes is Dwayne but is in fact Donyell, for the purposes of arranging an 'alliance'. Midnight's Fire leaves, telling Night Thrasher he would think about it. It's after the meeting that Midnight's Fire is working on behalf of another individual. He expresses displeasure at working with this entity.

Midnight's Fire is a Mutant like his sister Silhouette. His powers come from the Universal Wellspring.
Midnight's Fire has subtle para-human abilities. Due to the energies of the Well of All Things his physical attributes are raised to slightly beyond the peak of human possibility. He thus possesses enhanced speed, strength, agility, endurance and sensory perception slightly superior to Captain America; and he may well surpass these abilities as he grows in age and power. Midnight's Fire also possesses a degree of superhuman resilience; able to at least briefly survive a plunge into a pool of acetone without harm; and to fight an armoured Night Thrasher barehanded without suffering significant harm.
Midnight's Fire is also a skilled martial artist.

Milan

Milan is a member of the Acolytes, a super-powered team of terrorists that claim to follow the teachings of the villainous Magneto. Milan is one of the Acolytes who helped kidnap geneticist Moira MacTaggert. The group keep her in their current headquarters in a facility in France. Milan uses his powers to record various memories off Moira into the Acolyte computer systems. Moira is soon rescued by the heroic X-Men. With the other Acolytes, Milan leaves Fabian Cortez thanks to Exodus, and rejoin Magneto; they appear at Illyana's funeral, where they recruit Colossus. The X-Men attack Avalon, and Milan assists the Acolytes in defending it.

Milan is with a group of Acolytes searching for Omega Red in London, when Milan discovers evidence of his feeding, and Omega Red attacked Katu; Amelia Voght saves Katu and offers Omega Red a way to be freed from his constant need to feed on people. After Cable battles Omega Red, the Acolytes offer Cable a truce and help in defeating their mutual enemy. Omega Red attacks the Tyuratum Space Center, thinking they have the cure for his virus, and Cable and the Acolytes arrive a few hours later. Milan finds the center's director and reads his memories, learning that Omega Red found what he wanted, and the Acolytes tell Cable that Omega Red will need to go into space to administer the cure. They travel to Magneto's old Arctic base to teleport to Avalon, but Cable finds that Omega Red has already been captured at the base by the Acolytes, who reveal the trap they have laid for Cable as well. Cable escapes by ordering the lights to turn off; Milan and Cargill search for him, but Cable captures Milan. Cable is able to stop the Acolytes from using Omega Red in their plan to release his virus as a shield to keep humans from getting to Avalon. Milan is later present at the trial of the Neophyte. He talks about the recruitment of the young man in question. He and several other Acolytes had talked to the man through an abandoned church door for two days. This attempt works. Ultimately, because of the trial, Colossus is forced out of the Acolytes.

Milan is the one to fix Avalon's teleportation systems, after Cable disables them in X-Force #25. Milan is present with the Acolytes and X-Men when the universe is destroyed and replaced with the Age of Apocalypse. The Age of Apocalypse universe ends, and the mainstream universe is restored. Holocaust survives his alternate universe's destruction and somehow appears in the mainstream universe when it is restored; he is taken aboard the space station Avalon, the home base of the Acolytes. At this point, the group is being led by Exodus, who taken over when Magneto was rendered mentally inert by Charles Xavier. Milan studies the emaciated form of Holocaust and conveys to the group that what they have is indeed a mutant. Milan agrees with Peter Rasputin, Colossus that bringing the man aboard was not a good idea. For this doubt, he is assigned solitary guard duty on Holocaust. Milan ponders doubts that Exodus might not be the best leader. He receives a psychic flash from the captive and thus learns many details of the 'Age Of Apocalypse' universe, most notably that Magneto led the X-Men. Moments later, Holocaust consumes Milan from the feet up. Rusty Collins, a fellow doubting Acolyte is sent to investigate Milan's vanishing. Holocaust consumes him as well.

Milan had the ability to convert brainwaves into electromagnetic emissions and vice versa. He could use his power to project thoughts in the form of movies, and communicate with machinery through direct mental interface.

Mole established a temporary hiding place in the basement of Acme Records.

Mondo 
Mondo is the name of two characters which have appeared in the series Generation X. The first Mondo was a superhero later revealed to be a clone of the supervillain Mondo, who appeared years later. The first Mondo debuted in Generation X #3.

Not much is known of the Samoan mutant called Mondo. He was once friends with Cordelia Frost, Emma Frost's younger sister. In an attempt to make a bid for the position of White Queen of the Hellfire Club, Cordelia had Mondo contained and handed him over to the Inner Circle of the Hellfire Club. Cordelia's scheme backfired; the Hellfire Club kept Mondo but denied Cordelia membership. Cordelia went to Emma, headmistress of the Massachusetts Academy, for help and, soon after, Mondo was rescued by Generation X and subsequently accepted an invitation to join the school.

Generation X later learned that the Mondo they had rescued wasn't the real Mondo but a clone, a plant-based simulacrum created by Black Tom Cassidy who had infiltrated the Hellfire Club and rescued Mondo. After taking Mondo under his wing, Black Tom created a clone of the young mutant to infiltrate the Massachusetts Academy so that Black Tom could exact vengeance on his cousin, Banshee, who was the headmaster of the academy.

As Banshee and Emma Frost battled Black Tom, the Mondo clone began hunting down the members of Generation X. As the Mondo clone was about to attack Jubilee, he was killed by Bastion.

Later, the real Mondo appeared alongside Black Tom and Juggernaut. Completely loyal to Black Tom, the real Mondo battled the members of Generation X. Generation X attempted to talk to Mondo into not fighting, but Mondo laughed at them, reminding them that he has never met them before. Generation X and their teachers were able to defeat their opponents, but the trio still managed to escape.

Mondo was confirmed to be alive and powered as he appeared with the rest of Generation X during Cyclops' Million Mutant March in Washington D.C.

Mondo has recently appeared in X-Men Blue issue #8 alongside several other mutants in an effort to hunt down the young X-Men Blue team. This team's leader is Emma Frost, as she is part of the mutant sovereign state New Tian during Marvel's Secret Empire story arc.

Mondo is capable of taking on the properties of any organic or inorganic material with which he comes into contact. When using his power, Mondo is able to grow in mass with an assumed proportionate growth in strength to superhuman levels.Mondo can absorb matter into his body, gaining the mass, appearance, and other properties of the matter in question.

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

Moondark operated as a stage magician in San Francisco, and when Spider-Man came to town he feared that Spider-Man would interfere with his plans. While Jack Russell observed his performance at a small bijou, Moondark mesmerized the whole audience including Jack (also known as the Werewolf). Moondark sent the Werewolf to ambush Spider-Man at the San Francisco Bay, where he was vacationing. As the two heroes fought, Spider-Man discovered and tackled Moondark, who was killed as he fell into the water.

The Dark Beings whom Moondark worshipped claimed his soul but allowed him to return to Earth to claim other souls and buy back his own. He acted as a stage performer at a carnival in New York and created a Soul-Orb to claim the souls of the other carnival performers one by one. The Ghost Rider, Johnny Blaze, while working at the carnival also lost his soul to Moondark, which Moondark kept in a ring he wore. Spider-Man, as Peter Parker, went to the carnival and recognized the Ghost Rider who was now a part of Moondark's show. Parker returned as Spider-Man, but was captured by the Ghost Rider and the others under Moondark's control. When Moondark tried to steal Spider-Man's soul, he was able to destroy Moondark's ring and free the Ghost Rider, who destroyed the Soul-Orb with a burst of hellfire. Moondark's demonic master arrived to take the only soul available—Moondark's.

Moondark was able to return to the living world, seeking to reclaim Blaze's valuable soul to bargain for his own. Lairing outside Las Vegas, he sent mutated vultures to attack Blaze and attract his attention. He tricked Ghost Rider into resuming human form, subdued him and bound him with magical bonds that prevented him from transforming. Hamilton Slade, then known as the Phantom Rider, was nearby and drawn to the magical conflict. When Moondark attacked Slade, his concentration weakened which allowed Blaze to break free and transform into Ghost Rider again. Ghost Rider destroyed the new Soul-Orb and Moondark fled to his other-dimensional realm.

Moondark joined forces with the Water Wizard to get revenge on Blaze. Moondark enhanced the Water Wizard's power which allowed him to overpower Ghost Rider, and Moondark appeared and mocked the seemingly helpless Ghost Rider. Ghost Rider set Moondark's body on fire, and he fled back to his dimension.

Melissa Morbeck 
Melissa Morbeck is a fictional character appearing in American comic books published by Marvel Comics. She is an entrepreneur and the arch-nemesis of Squirrel Girl. The character, created by Ryan North and Erica Henderson, first appeared in The Unbeatable Squirrel Girl Vol. 2 #17 (February 2017).

Melissa Morbeck comes from a long line of women who were obsessed with wanting to control animals. After having become a successful engineering entrepreneur, she went about amassing an army of animals from every zoo and animal shelter by selling them tracking chips. After having witnessed the exploits of Squirrel Girl, Chipmunk Hunk, and Koi Boi, she manipulated the three into meeting each other and then attempted to turn Squirrel Girl into her protege by giving her enhanced equipment. Squirrel Girl's friend, Nancy Whitehead, deduced that Morbeck was a supervillain trying to amass an animal army and she revealed her true colors. The heroes eventually defeated Morbeck who was taken to prison after she pitifully tried to claim that Squirrel Girl was the villain. While in prison, she was visited by Ratatoskr who offers an alliance.

Morbeck plotted her revenge on Squirrel Girl, somehow recruiting major villains such as Taskmaster, MODOK, Dormammu, and her idol Doctor Doom. She also outed her identity as Doreen Green and blew up her apartment, though luckily no one was injured. To make matters worse, Morbeck also managed to hack Tony Stark's suit and took the name Iron Ring, a name that Squirrel Girl admitted was cool, but hated that Morbeck was the one to use it. A giant battle in Central Park took place with numerous heroes and villains showing up from both sides. The battle finally ended when Galactus, who previously formed a friendship with Squirrel Girl, showed up and sent all the villains to prison, Morbeck included.

David Moreau 
David Moreau is a fictional character appearing in American comic books published by Marvel Comics. The character's name is an homage to the title character of H.G. Wells' science-fiction novel The Island of Doctor Moreau.

While working for the island nation of Genosha, he developed a mind control device which made mutant slavery possible. Moreau created the mutate-process: all inhabitants of Genosha were tested at their 13th birthday for any presence of the X-factor gene. If they tested positive, they were turned into mutates: their memories were erased and their personality changed to become completely obedient, they were sealed in special suits and their powers were genetically changed to serve the needs of their country. At this time, Moreau became known as the Genegineer (a portmanteau of "Genetic Engineer").

Christian Davenport remarked that the atrocities committed by David Moreau are repeatedly related to the Holocaust and American slavery in the Genosha series of comics.

Moses Magnum 

Moses Magnum is a character appearing in American comic books published by Marvel Comics. A supervillain who first appeared in Giant-Size Spider-Man #4 (April 1975), he was created by Gerry Conway and Ross Andru. He is an arms dealer and terrorist.

Magnum was born in Ethiopia, but sided with Benito Mussolini's occupying army against his own people. Magnum later became a naturalized American citizen. He became president of the Deterrence Research Corporation (DRC), the world's foremost independent weapons manufacturing firm. As an arms expert, Magnum battled Spider-Man and the Punisher. Magnum surprisingly survived after the Punisher exposed him to chemical weapons. Then, he seemingly fell to his death after a battle with Luke Cage. However, Magnum was rescued by Apocalypse and granted superhuman powers which Magnum dubbed his "Magnum Force". His powers included superhuman strength and geologically based powers to cause earthquakes and sense disruptions in the Earth.

Magnum next threatened to create earthquakes to sink Japan unless he was named the nation's ruler. His plan was foiled by an assault by the X-Men and Sunfire on Magnum's Kuril Islands headquarters. Banshee disrupted Magnum's earthquake beam, but suffered a long-term loss of his own sonic powers in the process.

Re-establishing his company as Magnum Munitions, Magnum purchased the classified Deathlok cyborg technology from Cybertek. After the criminal High-Tech stole the technology, Magnum sent one of his agents in a massive Terrordome weapons platform to retrieve it, but was thwarted by Deathlok. Magnum subsequently bid against rival weapons manufacturers A.I.M. for a defense contract, destroying their world headquarters after they refused to withdraw their bid. Magnum used the subsequent profits to outfit a new army, conquering the African nation Canaan and seeking to restructure it into a homeland for African-Americans. Magnum then sought to ensure Canaan's economic independence by invading neighboring Wakanda, but Wakanda's king, the Black Panther, foiled the invasion with Deathlok's aid.

Later, Magnum's efforts to regain control of his power and destroy a floating resort using a stolen experimental seismic cannon were foiled by the combined efforts of the Avengers and future Avenger Triathlon. His own powers opened a fissure beneath him, seemingly sending him falling to his doom. Magnum somehow survived the fall, though how has not been revealed. At that time, he was present at the Pan-African Congress on the Treatment of Superhumans.

He next encountered Spider-Man. During the Dark Reign storyline, Moses escaped from prison through a plot by Norman Osborn to give Daken good publicity and was almost killed by a massive explosion intended by Osborn to clean up the resulting mess.

Magnum next appeared in Iron Man/Thor attempting to sell a special satellite he invented.

Moses Magnum's body generates seismic force which amplifies his natural strength, gives him an unknown degree of durability and attunes him to seismic vibrations. He can unleash this energy to cause vibratory shockwaves, minor tremors or devastating earthquakes. These waves will emanate from his body in all directions unless he purposefully tries to channel them in a single direction, usually along the length of his arms and through the tips of his fingers.

Moses Magnum in other media 
Moses Magnum appears in the Iron Man: Armored Adventures episode "Panther's Prey". This version is a mercenary who lacks powers and killed T'Chaka as part of a coup.

Mother Night 

Mother Night (Susan Scarbo) is a supervillain appearing in American comic books published by Marvel Comics. Mother Night first appeared in Captain America #123 (March 1970), and was created by Stan Lee and Gene Colan.

Susan Scarbo was born in Teaneck, New Jersey. Susan and her brother, Melvin Scarbo, formed a sibling hypnosis stage act for profit. They quickly became professional criminals, hypnotizing innocent people into doing their bidding. Under the name Suprema, Susan soon attracted the attention of the Red Skull who hired Susan as a nanny for his daughter, Synthia Schmidt. Under Susan's tutelage, Synthia later became Sin.

After a successful infiltration of the original S.H.I.E.L.D. organization and an attempt at stealing a Wolverine Jet from them, Suprema became an enemy of Captain America. After some time, Susan was revealed as an aide to the Red Skull, and his daughter Sin's tutor, nanny, and instructor. Changing her name to Mother Night, she became the headmistress of the Sisters of Sin team for a short while, and was revealed to be running the Red Skull's youth indoctrination hate camp. When Magneto captured the Red Skull, Mother Night became a member of the Skeleton Crew in an attempt to rescue the Red Skull. She battled the Black Queen and her Hellfire Club mercenaries. She aided the Crew in the rescue of the Red Skull, and it was insinuated that she has or had a personal relationship with the Red Skull.

Mother Night, with the Machinesmith and Minster Blood (her brother Melvin), then brainwashed the Avengers' support crew. She attacked the Avengers by forcing them to relive their greatest nightmares, but she was captured by Vision. After this Red Skull replaced Mother Night with Viper as his lover. She then betrayed him for his actions toward Captain America and received a severe beating from Red Skull for it. Wishing to die at her ex-lover's hand, she asked Red Skull to kill her, to which he said no. Pitying her, teammate Cutthroat began an affair with Mother Night. This relationship ended when he was seemingly killed by Crossbones.

She and her team were eventually killed by the Winter Soldier.

Moving Shadow 
Moving Shadow is a fictional character appearing in Marvel Comics. Created by Doug Moench and Paul Gulacy, he first appeared in the MAX comics imprint Shang-Chi: Master of Kung Fu (November 2002). He is the supervillain half-brother of Shang-Chi.

Moving Shadow was born to the criminal mastermind Zheng Zu and raised in secrecy while highly trained in martial arts and assassination. After Shang-Chi's defection from his criminal organization, Zheng Zu groomed Moving Shadow to replace him. Under Zheng Zu's tutelage, Moving Shadow embraced his father's teachings and served him loyally without question. To ensure the success of his Hellfire weapon, Zheng Zu dispatched Moving Shadow to kill Shang-Chi and his allies Black Jack Tarr, Clive Reston and Leiko Wu. Eager to prove himself superior to his half-brother, Moving Shadow repeatedly clashed with Shang-Chi, who was previously unaware of his existence. Shang-Chi eventually emerged victorious after a vicious fight with Moving Shadow but refused to kill him. With his plains thwarted once again by Shang-Chi, an enraged Zheng Zu executed Moving Shadow for his failure.

Much like his half-brother Shang-Chi, Moving Shadow is a highly skilled martial artist and assassin. He is shown to be proficient in many forms of weaponry, including the jian.

Alyssa Moy 

Alyssa Moy is a fictional character appearing in American comic books published by Marvel Comics. A former lover and colleague of Reed Richards, Alyssa works as a scientist and has a genius-level intellect nearly equal to that of Reed. In some storylines, she acts as the de facto manager for the Fantastic Four, responsible for generating their aliases and visual identities. She first appeared in Fantastic Four vol. 3 #5 (May 1998), created by Chris Claremont and Salvador Larroca.

Alyssa Moy's rare appearances have been associated almost exclusively with the Fantastic Four. In one instance, she lends her hover car to help Reed and Ben Grimm to retrieve an essential item which a villain has tossed miles away. In another adventure, Alyssa and Franklin Richards battle the Warwolves, who pursue them through New York City. The wolves take on the form of civilians to try to entrap them. Alyssa witnesses the wolves killing at least one police officer, a sight from which she tries to shield Franklin. Alyssa and Franklin are soon rescued from the wolves by the Fantastic Four.

Moy and the others also face the other-dimensional bounty squad of Gatecrasher and her Technet. Everyone is transported to Otherworld to face the Captain Britain Corps, which is controlled by Roma. The incident has been triggered because Roma believed Franklin to be a threat to the multiverse. He uses his powers to save the group and the Human Torch convinces Roma that Franklin is better off with his family. Alyssa helps uncover mental manipulation that Reed has suffered. Her first clue to it is his failure to perform as expected during one of their long-running mental chess games. Alyssa also helps rescue the alternate-version Alysande Stuart from her extra-dimensional captors. Alyssa later returns to solicit Reed's help with 'Nu-World', a man-made planet designed to take refugees from our seemingly doomed Earth.

At some time in the far past, Reed Richards had proposed to Moy. Moy turned him down because she felt that they had a 'duty' to spread their genius-level genes as widely as possible rather than 'confine' themselves to each other. Reed did not reveal this to his wife Sue until some time after Moy had re-entered his life. According to the then-current Fantastic Four writer, Mark Millar, Moy will again play a role in the comic as he explores her relationship with Reed Richards in much more depth. Millar said: "It just always struck me that Reed would have had someone prior to Sue, since he's ten years older than she is. Also, Sue's so different from Reed and I felt the girl out there would be much more like he was, a female Reed Richards of sorts, and someone he'd have met at university. As luck would have it, Chris Claremont created exactly such a character and her name is Alyssa Moy. Her nickname in our story is Mrs. Fantastic and you'll see why when you read the first issue."

During a reunion, Alyssa suggested to Reed that both of them had married the wrong people, since neither of their spouses could fully understand their work. However, Reed informed Alyssa that he married Sue because he loved her.

The Alyssa of eight years into the future of 'Nu-World' is now a floating brain in a robotic body, still married to Ted Castle, helping to keep the planet from being destroyed. This world comes to interact with the modern Fantastic Four because time has become corrupted there. She is slain by her enemies.
