## Icarus

Icarus (Joshua "Jay" Guthrie) is a mutant superhero. He was a member of the student body at the Xavier Institute and a member of the New Mutants training squad. Jay was the son of Thomas and Lucinda Guthrie. Thomas dies early in Jay's life due to black lung, developed from working in local Kentucky coal mines. Jay's older siblings Sam (Cannonball) and Paige (Husk) are mutants as well, and both have been members of the X-Men. When he himself developed mutant powers, he hid them from his family. When performing in his band, he exposed his wings to the crowd as a 'stage gimmick'. Believed to be descended from the ancient race of Cheyarafim mutants, Icarus possesses red feathered, angel-like wings which allow flight and produce regenerative enzymes allowing him to recover from normally fatal injuries. When his wings were removed, he lost his healing factor. His voice is capable of producing sonic frequency beyond the range of human capability as well as creating multiple sounds or voices at once.
Icarus is among the 198 mutants who retain their powers after M-Day, when the Scarlet Witch depowered most mutants on Earth. However, William Stryker convinces him to remove his wings in exchange for his friends' safety before killing him.
Icarus is among the many mutants who are resurrected by the Five following the foundation of Krakoa as a sovereign nation.

Ink (Eric Gitter) is a fictional superhero character appearing in American comic books published by Marvel Comics. The character was created by Marc Guggenheim and Yanick Paquette. As a member of the Young X-Men, the character is depicted as a normal human being who gained superpowers after being tattooed by a mutant. Each of his tattoos gives him a different power.

### Fictional character biography

Ink is one of the founding members of the Young X-Men team that believed themselves to have been organized by Cyclops. He is a loud-mouthed and rude teenager with a criminal past. He is introduced when two police officers attempt to arrest him in a tattoo parlor. He fights back using his newly acquired ability to make others violently ill with a touch by utilizing a new tattoo on his hand of a biohazard symbol, making the police officer instantly very sick. Despite this, he is arrested anyway. While Ink waits in jail, a prison guard releases him, in the process revealing himself to be Cyclops, leader of the X-Men. In short order, Eric is recruited into Cyclops' junior X-Men team. The teens are assembled in the Danger Cave, a training facility where they train for their first mission: assassinating the original members of the New Mutants who have gone rogue.
Cyclops sends Ink and a fellow recruit, Blindfold, to attack Dani Moonstar. On their way to Moonstar's cabin, they had a conversation where Blindfold implied Ink was not a mutant. They were successful in their mission, and just after Blindfold knocks Moonstar unconscious, Ink betrays her and knocked out Blindfold, warning her that she should have seen that coming. Ink was paid to deliver both Blindfold and Moonstar to Donald Pierce, which he did, though he refused to kill them. He delivers the two women to Pierce, who refers to him as a mercenary. "Cyclops" is later revealed to be Pierce in disguise, whose goal is to manipulate the Young X-Men into killing the former New Mutants. Upon learning this, Ink appears to suffer a crisis of conscience and leads the Young X-Men and New Mutants to Pierce's hideout. They subdue Pierce, but not before Wolf Cub is killed, leaving Ink to deal with his own feelings of guilt over his involvement.
Later, it is revealed that Ink is actually a normal human being, and that his tattoo artist, Leon Nunez is a mutant. Presumably, the tattoos he draws gave Ink his powers because Ink explains the desired functions of each tattoo prior to getting them to Nunez. Emma Frost runs a scan on him at Dani Moonstar's request that confirmed him as a baseline human, and Pierce knew this before he recruited him. Ink takes the knowledge hard and quits the team, feeling unwelcome already for his involvement with Pierce. While wandering San Francisco drunk, he is attacked by the Hellfire Cult, a mutant-hating gang. Ink easily defeats them, telling them that he's not a mutant and they wasted their time. Then a girl named Cipher appears and tells him he's still an X-Man and his friends are being attacked by the Y-Men, a group of gang members similarly empowered like Ink by his tattoo artist. Together they go to Nunez and force him to give Ink two new tattoos, a caduceus symbol on his left palm and the Phoenix Force symbol over his eye, much like Phoenix-hosts Jean Grey and Rachel Summers. They then go save the Young X-Men from the Y-Men. Ink saves and heals Dani Moonstar with the caduceus tattoo and defeats the Y-Men with his Phoenix powers, explaining that he believed the Phoenix Force to be omnipotent, thus granting him the ability to remove the Y-Men's tattooed powers.
It is decided later that Ink will stay with the X-Men and train, Cyclops not wanting someone to run around with Phoenix-like powers unwatched. Moonstar and Sunspot explain that inking powered tattoos saps Nunez's willpower and that adding the Phoenix Force tattoo to Ink pushed him too hard, leaving Nunez comatose. In this state, he is barely conscious enough to maintain Ink's powers, though if he ever wakes up, Ink will revert to a normal tattooed human. Graymalkin later offers his friendship to Ink, noting that he too understands what it feels like to be different and ostracized. When Dust begins to die from a hidden health condition, Ink attempts to heal her with his caduceus tattoo, but fails. Her death upsets him, causing the others to realize that he now cares about the team. He later speaks to her prepared body, stating that she is the last person to deserve death and he is the first. Knowing that his Phoenix tattoo is untested, he uses it to revive her. He is successful, but the strain leaves him comatose, Beast stating that his mind has activity, but is subdued, "as if it's been overcharged". Beast also postulates that his current state is because his tattoo could only approximate the powers of the Phoenix and that he never actually contained the true energies associated with the Phoenix Force, making his actions an incredible strain. His actions may have ramifications for the future, with the last two issues of Young X-Men depicting a dystopian future and a villainous and powerful Dust seeking to kill all mutants and Ink in particular for "killing her soul" by reviving her.
He appears in unexplained full recovery containing the San Francisco riots, as well as later in the fight against the Dark Avengers, alongside other X-Men in the Dark Avengers/Uncanny X-Men: Utopia storyline.

### Powers and abilities

Ink has no powers of his own. Instead, he had access to a mutant tattoo artist, Leon Nunez, with the power of granting superpowers to other beings by tattooing iconic "power symbols" on them, evocative of the power he wants to bestow. The downside to this is that it takes away a little bit of Nunez's will every time he does it. Nunez made Ink believe that his powers were his own, purposely misleading him into believing he was a mutant. Since granting Ink his last tattoo—the omnipotent Phoenix Force symbol around his eye—Leon Nunez has been in a catatonic state. If he were to wake up, it is thought that Ink's power would disappear, leaving him a normal boy. This was not the case however as Eric was able to get more body art after his phoenix tattoo was removed and he had obtained new body art.

### Other versions
#### Young X-Men "End of Days"

In a dystopic future depicted in the final two issues of "Young X-Men", a disproportionately aged, wheelchair-using, heavily tattooed, and seemingly brain dead Ink lives on "Xaviera", a former mutant safe-haven independent state and utopia along with adult versions of Anole and Graymalkin and an aged Emma Frost (now calling herself "Diamondheart"), and Wolverine, the only four remaining mutants on Xaviera. Emma constantly hopes that he will awaken and speak, though Wolverine states that he never does. Dust suddenly appears, now greatly changed in her appearance and persona with altered powers. She quickly confronts and kills the others and finds Ink. It is then that Ink speaks, acknowledging her presence. They discuss Sooraya's resentment of mutants "allowing her to die" and how Ink "killed" and "corrupted" her soul and making her what she is now by reviving her. Ink states that he was trying to do the opposite and asks her if she recognizes the gravity of her actions. Understanding that she does not, he tells her to get it over with and she kills him, stating that she is sorry as she knows that his heart was in the right place.

### Ink in other media

Ink appears in X-Men: Days of Future Past, portrayed by Gregg Lowe. This version is a G.I. during the Vietnam War whom William Stryker attempts to capture for Bolivar Trask's experiments before Mystique rescues him. In an alternate 2023, he is a prisoner of the Sentinels.

He enlisted Sally's help in this endeavor, but became jealous when she flirted with Spider-Man. Later, Jason ran a red light while trying to catch Spider-Man, but collided with another vehicle. Sally was killed, and Jason suffered mild head trauma. Jason was left feeling bitter and soon turned on Flash and his friends. Later, Peter throws a party for Jason and Tiny, but Jason refuses to accept Peter as a friend. He later saves Liz during a fight between Spider-Man and the Headsman. Jason becomes depressed and attempts suicide, but is stopped by the Vulture who convinces him to blame Spider-Man for his problems. Jason disguises himself as Spider-Man and starts committing vandalism and brandishing a gun in an attempt to damage Spider-Man's reputation.

During the siege of Asgard, the Iron Patriot is disabled during Osborn's fight with Steve Rogers and Tony Stark of the Avengers which revealed warpaint which tried to contain his Green Goblin alter-ego.
The Iron Patriot armor has been programmed with a low-level A.I. seen during the Marvel NOW! event. At a weapons expo, the Iron Patriot ends up stolen by A.I.M. for the Scientist Supreme's plans which is almost interrupted by Nick Fury Jr. and Daisy Johnson. An army of Iron Patriot drones are controlled by Marvin Flumm in order to incriminate the United States in international attacks, such as a framed attack on Iran where the Hulk is sent in response. Phil Coulson of S.H.I.E.L.D. uses holographic communication to hack so the Iron Patriot drones can understand these programmed actions are wrong. The Iron Patriot drones are next seen during the Inhumanity storyline as support.

## Isca the Unbeaten

Isca the Unbeaten is a fictional character appearing in American comic books published by Marvel Comics. Created by writer Jonathan Hickman and artist Pepe Larraz, she first appeared in X-Men (Vol. 5) #12 (September 2020). She is a mutant whose powers prevent her from ever losing.
Isca lived on the ancient island of Okkara and was the younger sister of Genesis. When the Amenthi Daemons invaded the island and split it into Krakoa and Arakko, Isca initially fought alongside her fellow mutants. However, when it became clear that the forces of Annihilation were going to win, her powers compelled her to defect to the Daemons. After the entire mutant population and Arakko were sealed away in Amenth to stymie the invasion, Isca continued to fight against her people for Amenth. After millennia of battle, Annihilation sent Isca to her sister Genesis with a proposal for the queen of Arakko to face the dark ruler of Amenth in a duel to death and end the war. This was ultimately a trap: by killing Annihilation's host, Genesis was forced to become its new host in order to prevent the uncontrolled Daemons from destroying Arakko. Following Arakko's subjugation, Isca aided her lover Tarn the Uncaring in quelling dissent, imprisoning and torturing those who refused to submit to Annihilation.
Isca was among those recruited to fight in the X of Swords tournament on behalf of Arakko. She dueled Captain Britain in the first round and won, shattering her opponent into glass-like pieces. Though she won all subsequent challenges she participated in, the Krakoa team managed to win the tournament. Annihilation, refusing to accept defeat, summoned the full might of Amenth's forces to conquer Krakoa. Isca initially fought against the Krakoan mutants. When the arrival of the X-Men, the Captain Britain Corps, and the Vescora turned the battle in Krakoa's favor, her powers again compelled her to defect to the opposing side. At the battle's conclusion, Isca traveled to Earth with the rest of the Arakkii mutants and claimed a seat on Arakko's ruling body, the Great Ring of Arakko (though she abstained from voting so her powers would not influence other members' votes). She later assisted Magneto in terraforming Mars to be a suitable home for Arakko and traveled there when the island was relocated.
Isca's service in the Great Ring was marked by frequent ideological clashes with Storm, the new Regent of Arakko. During the duel between Magneto and Tarn for the latter's seat on the Great Ring, Sunspot tricked Isca into wagering against Tarn, resulting in her lover's death. When the Eternals declared war on mutantkind and sent Uranos to attack Planet Arakko, Isca's powers compelled her to defect to their side and she killed fellow Great Ring member Idyll the Future Seer. Nightcrawler teleported her to the ocean where Sobunar of the Depths kept her occupied fighting various sea monsters until Uranos was defeated. At the conflict's end, the Great Ring confronted Isca. Defiant, she threatened to take over the Ring until the Fisher King challenged her to a contest of understanding, in which the winner would be the one who truly understood loss. Though she had never experienced it since her powers manifested, Isca's powers granted her comprehension of loss. Realizing her mistakes, Isca subsequently resigned from the Great Ring and went into self-imposed exile.
After Genesis returned to Arakko and incited a civil war, Isca remained neutral, claiming Olympus Mons and the Tharsis Montes as her domain and killing any who trespassed, regardless of their allegiance.

### Powers and abilities of Isca the Unbeaten

Isca is an Omega-level mutant with the power to never lose. Her powers will give her the skills required to win, manipulate probabilities in her favor, or slightly alter her appearance. In larger conflicts, she will be compelled to switch to the side that is most likely to win. Her power will also make her win even if victory is unfavorable for her. Isca's powers cannot be negated and they do not make her immune to dying or being killed if her death would result in her victory.
Isca is also very long-lived, having been alive for over 10,000 years.
In combat, she wields a sword named Mercy.
