Jackdaw is a fictional character featured in the Marvel Comics universe. He was created by Dez Skinn, Steve Parkhouse, Paul Neary and John Stokes, and first appeared in The Incredible Hulk Weekly #57 (April 1980).

A now-deceased hero, the sidekick of Captain Britain, Jackdaw was an Otherworld elf. Jackdaw had been mortally wounded earlier in his adventures, but was revived by Merlyn and given new powers and a new costume.

He was permanently slain later on Earth-238 by The Fury. Jackdaw was literally torn in half by one of the Fury's energy bolts and expired shortly thereafter in Captain Britain's arms. Jackdaw expressed a belief that Merlyn would resurrect him. Saturnyne had abandoned them (and her assistant Dimples, who loved her deeply) to escape.^[1] Merlyn did not resurrect Jackdaw as it would have damaged his chances of rescuing Captain Britain, who was killed as well by the Fury after Dimples and Jackdaw, and resurrected by Merlyn back on Earth-616.^[2]

The Skull intended to take over first New York City, then the world. Along with the Skull's other slaves, he was forced to fight a team of super-mutants led by Captain America; in the end, the Skull was killed and his slaves were freed.

Jade Dragon would move on to work alongside Iron Maiden, Black Bolt, and the Iron Avengers.

Jetstream (Haroun ibn Sallah al-Rashid) is a fictional Moroccan mutant character appearing in American comic books published by Marvel Comics. Created as a part of the group known as the Hellions, he exists in Marvel's main shared universe, known as the Marvel Universe. His first appearance was in The New Mutants #16.

Haroun ibn Sallah al-Rashid was born in the Rif Mountains in Morocco. As Jetstream, he was a student and operative of the White Queen and member of the original group of Hellions, the trainee group of mutants set up by the Hellfire Club to be a rival to the New Mutants. Haroun felt obligated to be part of the group; they gave him cybernetics to stop his powers from causing self-injury.^[17] Jetstream was the antithesis of Cannonball, who could also propel himself through the air and was also the team leader. He engaged in several battles with the New Mutants—mostly petty competition—but occasionally got along with the students, sometimes having dances for socialization.

On the first mission of the Hellions, Jetstream helped to capture Doug Ramsey and Kitty Pryde from the X-Mansion. When the New Mutants came to reclaim their own, Jetstream was defeated by Magma, and quarreled with fellow Hellion Empath. The two teams decided to solve the dispute their own way: a duel between Cannonball and Jetstream with the winner getting to keep the captives. Jetstream lost, but Emma Frost returned in time with Sebastian Shaw to deter the New Mutants from retrieving their friends. Kitty was able to create a diversion for Magik to be able to transport the team to safety.^[18] Later, when the New Mutants were in a state of emotional turmoil over being killed and resurrected by the Beyonder, Emma Frost saw it as her opportunity to sweep in and take control. She convinced Magneto—the current leader of the team—to allow the New Mutants to come to the Massachusetts Academy for psychic counseling, where she promptly accepted them into the ranks of her Hellions. The two teams became quite fond of one another, and Jetstream was able to challenge Cannonball to another duel, but the teams were separated when Magneto realized that his emotions had been manipulated by Empath to convince him to relinquish the students.^[19]

Jetstream later used his skill with computers to find Empath, who had been captured by the New Mutants.^[20] Jetstream later repeated his challenge to Cannonball at a Hellfire Club gala. He also participated in the Hellions' capture of Viper and Silver Samurai, and the Hellions' unsuccessful attempt to capture Bird-Brain.^[21] After that, Jetstream joined in the Hellions' mock attack on new recruit Magma during a training session.^[22] On the team's final mission, Jetstream went along with the Hellions in order to retrieve former-member Firestar. They found her in the ranks of the New Warriors and their leaders, Tai and the White Queen, decide to have a series of fights to see who would get her, whichever team defeated more of the other won. This deal was unknown to either team as they were already fighting. Jetstream was defeated by Nova who ended up punching him through a wall. The Hellions, as a team, lost and went home, not knowing that their young lives would soon be over.^[23]

Soon after, Emma threw another party which the Hellions as well as the X-Men Gold team attended. It was there that Trevor Fitzroy—a member of the villainous group known as the Upstarts—crashed the party with the goal of killing Emma in order to gain points within the group. The Hellions were mere formalities: Jetstream was killed in the opening salvo of the crossfire by Fitzroy in order to fuel his teleportation portal.^[24]

Jetstream was a mutant who could generate thermo-chemical energy, accompanied by plasma (a super-heated state of matter), and release it through his skin. Jetstream could only release this energy downward beneath him, and the result was that it propelled him through the air like a human rocket. He could also release energy from all of his limbs, thus delivering at close to the speed of sound. Jetstream's body was immune to damage from the intense heat released by these energy discharges and by the plasma. He could not fly beyond a certain undefined distance without temporarily exhausting his energy powers. However, Jetstream's body was unable to withstand the tremendous energies he generated—one day his flesh even caught fire as he flew. To save him and enable him to use his power, the Hellfire Club provided Jetstream with a Frost Industries bionic system. Among these systems was a bionic backpack that could fold away into his body which contained computerized scanning devices and aerial navigation, and rockets in his thighs to help better contain, focus, and control his power. Jetstream was a fair hand-to-hand combatant, having been trained at the Massachusetts Academy. He was also skilled in utilizing computers.

Jiang Li is the mother of the hero Shang-Chi, who debuted in Shang-Chi (vol. 2) #4 (September 2021). The character was created by Gene Luen Yang and Dike Ruan, and is based on the Marvel Cinematic Universe (MCU) character Ying Li, portrayed by Fala Chen in the film Shang-Chi and the Legend of the Ten Rings (2021). As a Qilin Rider, Jiang Li is blessed by the Xian with the power of innate archery and to psionically link with qilin. Jiang Li can also extend her psionic abilities to other individuals, including humans and aliens. She is also proficient in martial arts.

In the early 1970s, writer Steve Englehart and artist Jim Starlin developed the character Shang-Chi, a master of kung fu and a previously unknown son of Dr. Fu Manchu.^[25][26] Shang-Chi's mother was a white American woman, per mandate^[27] by then editor-in-chief Roy Thomas, who was genetically selected by Fu Manchu to be the mother of his progeny.

The name Jiang Li was originally used for Shang-Chi's mother in Shang-Chi and the Legend of the Ten Rings, in which she is depicted as an Asian woman, although the name for the film character was ultimately changed to Ying Li.^[28][29] Following the film's release, Shang-Chi comic writer Gene Luen Yang incorporated several concepts introduced in the film into the Shang-Chi mythos, including the character Jiang Li as Shang-Chi's real mother, who was based on Shang-Chi's mother Ying Li,^[a] retconning Shang-Chi's white American mother and his mixed-race heritage; the heavenly realm Ta-Lo, which was previously introduced by writers Mark Gruenwald, Ralph Macchio and artist Keith Pollard in Thor #310 (1980);^[32] and the Ten Rings weapons.^[33] Refinery29 reviewer Leah Marilla Thomas praised the newer incarnation of the character for the "mythical (and devastatinlgy romantic) backstory", which makes her a "real character" as compared to the brief appearances in earlier comics.^[34]

Jiang Li was born into one of Ta-Lo's few communities of mortals known as the Qilin Riders who were appointed by the Xian as guardians of the gateway connecting Ta-Lo to Qilin Island in the East China Sea. While on patrol, Jiang Li rescued a shipwrecked Zheng Zu from pirates. Jiang Li nursed Zu back to health and the two fell in love. However, Jiang Li's father, Chieftain Xin, was outraged over her harboring an outsider and ordered her to return to Ta-Lo with Zu's head. Instead, Jiang Li and Zu fled to Zu's House of the Deadly Hand in Hunan, where Jiang Li discovered Zu's true identity as the leader of the Five Weapons Society, a criminal organization. Jiang Li attempted to leave him, but Zu pleaded with her to stay, promising to change his dark ways. True to his word, Zu rediscovered his own humanity from Jiang Li and the two married and had two children: Shang-Chi and Shi-Hua.^[35] However following an attack by Hydra against the House of the Deadly Hand, Zu became cold and distant towards his family, as he felt that his love for them made him weak. Out of loneliness, Jiang Li sent a letter to her father and a few weeks later was drawn to a confrontation between Xin and Zu in the latter's personal tower, where it was revealed that Zu had constructed a makeshift portal to Ta Lo to steal the realm's sacred weapons to bolster the Society. While Zu fought his wife and father-in-law, Shang-Chi happened upon the scene, just as the portal's connection to Ta Lo became disconnected and Jiang Li was accidentally pushed through to her presumed death.^[36]

Instead, Jiang Li was sent to the Negative Zone, where she used her psionic abilities to mentally link with the native mantid creatures, who protected and sheltered her. Jiang Li resided in the Negative Zone for many years, occasionally using her psionic abilities to reach out to her children. After Shang-Chi took over the Five Weapons Society following Zu's death and began reforming it as a heroic organization, he began receiving Jiang Li's messages through his dreams and travelled to the Negative Zone with his half-siblings to rescue her. While she recuperated at the New House of the Deadly Hand in Chinatown, Manhattan, she is secretly visited by her father. Despite claiming to being overjoyed to see her again, Xin is consumed by his rage towards Zu and his bloodline since his earlier confrontation with them and believes Shang-Chi to be as evil as his father, vowing to put an end to his grandson.^[37]

Due to being mentally linked to insects for many years, Jiang Li takes a while to recover her mental health but spends time with her son and his half-siblings.^[38][39] After she fully recovers, Jiang Li begins telling Shang-Chi their family history but the two are attacked by several enemies of the Society. Jiang Li uses her psionic abelites to realize that they are being led by Xin.^[35] Although Shang-Chi and the Society are able to defeat the would-be assassins, Jiang Li is taken hostage by them, forcing Shang-Chi to let them escape. Although Xin is outraged over their failure to kill Shang-Chi and for kidnapping his daughter, he allows his allies to escape with Jiang Li through a portal to Qilin Island and through the gateway to Ta Lo.^[36] After failing to acquire Shang-Chi's corpse to complete his magic, Xin forcibly extracts Jiang Li's psionic energy to locate Shi-Hua for his ritual.^[40] Xin returns with Shi-Hua's severed right hand, which he uses to create taotie masks for himself and the Qilin Riders. Jiang Li escapes by psionically bonding with a nearby qilin and travels back to Earth to help the Society defend the House of the Deadly Hand from the mask empowered Riders.^[41] Jiang Li briefly faces off against her father, who is empowered by his own mask and several of the heavenly Ten Rings but helped by the arrival of Shang-Chi and his siblings. When Shang-Chi succumbs to his inner darkness to take the Ten Rings from Xin and defeats him and the Riders, he attempts to sever Xin's hand in retaliation for what he did to Shi-Hua but Jiang Li and his siblings talk him down, bringing him back to his senses. Jiang Li and Shang-Chi return to Ta Lo for Xin to face justice and to return the Ten Rings to the Jade Emperor, who appoints Jiang Li as the new Chieftain of the Qilin Riders, which requires her to remain in Ta Lo.^[42]

Giachomo "Jimmy-6" Fortunato is a fictional character appearing in American comic books published by Marvel Comics. The character is featured in the Marvel Universe and is commonly associated with Spider-Man. He first appeared in the comic, Spider-Man #70 and was created by writer Howard Mackie and artist John Romita Jr.

When the Kingpin (Wilson Fisk) lost control of New York's underworld, crime lord Don Fortunato filled the power void. His son, Giachomo "Jimmy-6" Fortunato, disapproved of his family's methods and tried to quit organized crime just as his father's plans were coming to fruition. Enraged, Don Fortunato demands his son's death. On the run, Jimmy-6 pushes Ben Reilly (a clone of Peter Parker) away from a barrage of bullets intended for him. As Spider-Man, Reilly returns the favor later by rescuing Jimmy-6 from an assassination attempt. Although the wounded Jimmy-6 wants nothing to do with Spider-Man, he reluctantly accepted Reilly's offer to hide out at his apartment.^[43] Hoping that Jimmy-6 could still be persuaded to return, Don Fortunato orders that he be captured rather than killed. Shortly after meeting Reilly's "cousin" Peter Parker, Jimmy-6 learns of an alliance of rival crime lords formed by gangster Hammerhead which plans to assassinate Don Fortunato. Jimmy went to warn his father of the planned hit, only to learn that Don Fortunato has formed an alliance with the HYDRA terrorist organization to defeat his rivals.^[44]

In a small ceremony, Fortunato reveals he has kidnapped civilians from each of the territories of the attending crime lords. Jimmy-6 learns the civilians are to be executed as an example of what would happen in case of disobedience. Horrified, Jimmy pulls a gun on his own father. The attendees wait and see what happens. Don Fortunato disowns Jimmy right there on stage. Spider-Man – then Ben Reilly – and Daredevil help rescue the civilians but need help themselves when they are cornered near an exit. Jimmy-6 flies in on an attack helicopter, killing the men threatening the group and carrying the heroes and civilians away to safety.^[45] Later, Jimmy-6 learns the Green Goblin (Norman Osborn) has killed Ben Reilly, and vows to avenge his friend's death.^[46]

Wounded by enemies of his father in Forest Hills, Queens, Jimmy-6 seeks refuge at the nearby Parker residence, where he stops an assassin sent by the Green Goblin.^[47] He then departs. When Spider-Man (Peter Parker) was suspected of murdering street thug Joey Z, Jimmy-6, feeling he owes Spider-Man his life, saves him from vigilantes trying to collect the $5 million bounty placed on Spider-Man's head.^[48] Soon after, Jimmy-6 shot a new Green Goblin (a genetic creation employed by Osborn), although the Goblin's armor saved him. Several vigilantes sought the bounty on Jimmy's head afterward, but the Punisher (Frank Castle) and government mercenary Shotgun (J.R. Walker) save him.^[49]

When the Kingpin returns to claim his criminal empire, Jimmy-6 challenges him and rejoins the Fortunato crime cartel, replacing his incapacitated father (allegedly hospitalized by Kingpin). Trying to stop the bloodshed, Jimmy-6 reaches an agreement with the Kingpin. Peter Parker is caught photographing a secret meeting between Jimmy and the Kingpin, but Jimmy lets Parker go due to his "relationship" to Ben Reilly.^[50] After one of Jimmy's men accidentally knocks over the Kingpin's high-stakes poker game, New York erupts in a gang war between rival underworld faction. When Jimmy and his family are caught in a crossfire involving Kingpin's Enforcers (Fancy Dan, Montana, & Ox), Spider-Man's intervention enables Jimmy to escape, and he later helps Jimmy defeat the Enforcers in Jimmy's penthouse.^[51]

Jimmy-6's current status is unknown now that Don Fortunato has regained his health and control of the cartel, but it was confirmed that Jimmy-6 had somehow made peace with his father, as Fortunato briefly refers to him as "My Beautiful Giacomo,"^[52] showing no signs of ill will. With Angelo dead after as short term as the second Venom, Jimmy-6 is in all probability the sole heir to Fortunato's crime empire.

Composed almost entirely of muscle, Jimmy-6's massive frame grants him peak human strength and resists many penetration wounds. He is a skilled strategist and electrical engineer, having designed the Fortunato estate's security systems. A veteran of two tours of duty with the U.S. Army, he is an accomplished hand-to-hand combatant, firearms user, and helicopter pilot.

Jimmy-6 appears in Spider-Man: Turn Off the Dark, portrayed by Gideon Glick.^[53] This version is a member of the Geek Chorus, a group of Spider-Man fans.

Joseph was briefly a member of the X-Men. Created by writer Scott Lobdell and artist Roger Cruz, he first appeared in The Uncanny X-Men #327 (December 1995).

Joseph is a clone of the X-Men's nemesis Magneto, possessing his magnetic powers, though he was originally intended to be an amnesiac Magneto. He had a brief courtship with Rogue before dying in battle with the actual Magneto. Joseph is later revived by Astra.

Joseph was discovered near a South American orphanage run by a nun known as Sister Maria. After several run-ins with "The Colonel", Joseph opted to leave the orphanage to protect the children. It was shortly after this that he encountered Rogue and saved her from the first wave of Bastion's "Operation Zero Tolerance".^[86] Rogue believed Joseph to be an amnesiac and mysteriously youthful Magneto. During this time, the X-Men first encountered the being known as Onslaught. Believing Magneto to be responsible, the Avengers sought Joseph out and figured out that he was not responsible nor was he like Magneto.^[87] Out of guilt for what he believed were his past sins, Joseph joined the X-Men in their war against Onslaught.^[88]

In an attempt to find out more about his past, Joseph encountered the Acolytes and their leader Exodus. They too believed that Joseph was Magneto and begged him to lead them. Exodus turned on Joseph when he noticed that Joseph was not the Magneto he knew. Joseph took on Magneto's identity to convince the Acolytes that he truly was Magneto and ordered them to abandon their current activities. Exodus disagreed, but obeyed because he believed he saw a glimmer of the old Magneto within Joseph. Joseph returned to the X-Men, satisfied that he no longer was Magneto.^[89]

Shortly afterward, Joseph dedicated himself to reconstructing the Z'nox chamber to give Rogue some control over her powers. It was successful, to an extent, in that while standing under it, Rogue was unable to absorb the powers or psyche of another person. Immediately after this, Joseph and some of the X-Men were sent to the Shi'ar Galaxy to fight the Phalanx. When they returned to Earth, they were captured. In captivity, Joseph met the mutant Maggott, who had been saved by Magneto years before, and expressed his gratitude to the confused Joseph. Maggott discovered though that their captor Erik the Red was the real Magneto in disguise. Feeling that he owed Magneto for saving him, he did not tell the X-Men that Joseph was not Magneto.^[90]

Several weeks later, the Israeli agent Sabra appeared at the X-Mansion and wanted to kill "Magneto". Maggott revealed to her that Joseph wasn't Magneto, confirming Sabra's suspicions. Joseph left with Sabra to find out more about his past and Magneto's current whereabouts. He was kidnapped by Astra, who told Joseph that it was she who had found the escape pod that came from the space station Avalon before it was destroyed. inside she found the bodies of Colossus and the comatose Magneto. This being the perfect chance to get revenge on him for the way he had treated her when she was one of the members of his original Brotherhood of Evil Mutants, she stole Magneto's body before Colossus woke up. But killing Magneto would have been far too easy, Astra wanted to humiliate him and so she proceeded to rebuild Magnus' damaged mind, in order to create a copy of him with full mental faculties. She used both Kymellian and Glyxian technology to create a perfect mental and genetic copy of Magneto at a younger age, without the self-imposed limits he had placed on his powers.

Astra then pitted her creation against the newly restored Magneto, laughing out loud as Magneto, unable to best his younger self in combat, was forced to flee. Believing to have seen enough, Astra ordered her creation to fulfill the task he had already started, while she teleported away to space. The clone caught up with Magneto over Central America, and the pyrotechnics of their confrontation could be seen for miles. In order to survive, Magneto was forced to resort to trickery, and struck his clone in the back of the head with a piece of debris, sending him falling to Earth. The impact destroyed what little memories the younger Magneto had.^[91]

In the meantime, the real Magneto had fully recovered and was once more blackmailing all of Earth's governments by manipulating the planet's electro-magnetic field from within his base near the magnetic North Pole. This event came to be known as the Magneto War. Astra forced Joseph into battling Magneto, seeing the chance to reach two goals at once – getting rid of her archenemy and enslaving the world by continuing where Magneto left off. The timely arrival of the X-Men thwarted her plans, though. With some members distracting Magneto and others keeping Astra busy, Joseph set to work re-aligning Earth's electromagnetic field, which was spinning out of control by the forces unleashed. Joseph's cloned cells couldn't handle the unlimited energies being channeled by his proximity to the magnetic north pole, and his physical form was destroyed, while his magnetic power and mental essence were merged with the EM field. His sacrifice saved the Earth and everything on it.^[92]

However, Astra revived Joseph by drawing his essence back out of the electromagnetic field and into physical substance once more. She didn't do this out of sentiment, but out of greed. Christopher Bach, leader of the anti-mutant activist group Humanity Now! was willing to harm his own people in order to drum up support for his cause. To do this, he wanted his own "Magneto" who could attack Humanity Now! rallies and feed public sentiment for his cause. Astra did her work restoring Joseph's mind, aligning it more with Magneto's traditional rhetoric than with the compassionate worldview Joseph developed as an X-Man. Joseph announces his comeback by murdering 40 anti-mutant campaigners while wearing Magneto's costume, leaving the real Magneto to take the blame. Joseph has also assembled his version of the Brotherhood of Mutants consisting of himself, Astra, and mutated versions of Blob, Mastermind, Quicksilver, Scarlet Witch, and Toad. It is soon revealed that the mutated versions of Blob, Mastermind, Quicksilver, Scarlet Witch, and Toad are clones created by Astra. All the clones were killed by Magneto. Joseph is defeated by Magneto and remanded to Utopia's X-Brig.^[93]

After the destruction of Utopia in the war between the Avengers and X-Men, Danger released all prisoners on the X-Brig, including Joseph. After the loss of Magneto, Joseph disguised himself as the Master of Magnetism and formed a new Brotherhood in the wake of the death of the X-Men. He brought them to an Air Force base in East Transia to stoke fear in humankind because of the spike in anti-mutant violence. But they were confronted by a new group of X-Men led by a resurrected Cyclops. After the battle, Joseph's ruse was revealed making Juggernaut mad because he thought the group was made to protect mutants. He attacked Joseph and held him down while Scott and him talked about ideologies. But before anyone could see what was going on, Joseph was killed by Kwannon who considered Joseph a threat to mutantkind.^[94]

As a clone of Magneto, Joseph possesses the superhuman power to generate extremely powerful magnetic fields. He can employ these magnetic fields to manipulate ferrous metals and to produce a number of other effects. He has also been shown to generate electricity and electromagnetic radiation. Joseph is capable of personal levitation/flight at high speeds, and often produces a protective magnetic aura around his own body. The real Magneto has on rare occasions been able to produce a wormhole using magnetism, and to safely teleport himself and others by means of the wormhole, but Joseph has not demonstrated a similar ability. It was revealed that the circumstances of his creation mean that he lacks the mental barriers that the original Magneto has established over the years to prevent himself from over-using his powers, with the result that Joseph can manipulate more energy than Magneto is capable of controlling on his own (Magneto requiring technological assistance to boost his powers to the same level as Joseph's full potential), at the cost of causing significant damage to Joseph if he pushes himself too far.

Josiah X is a fictional character, the son of Isaiah Bradley, the black Captain America, and the uncle of Elijah Bradley, the Patriot.^[95] The character was created by Christopher Priest and Joe Bennett, and debuted in The Crew #1.

Josiah is a Nation of Islam minister. He replaced his last name Bradley with the letter "X". He has had many names including "Justice", the one he used as a hero. The "X" apparently symbolizes his allegiance to the Lost Tribe of Shabazz. Josiah runs a Nation of Islam Mission in the "Mog" (Little Mogadishu) in Brooklyn, New York.^{[volume & issue needed]}

As depicted in the series Truth: Red, White & Black, the World War II Super Soldier program of 1942, operated by "Reinstein", used African American test subjects in a beta phase. The clandestine experimentation that empowered Josiah's father Isaiah Bradley held similarities with the Tuskegee Experiments. After a failed suicide mission to destroy the Super-Soldier efforts of the Nazis, Isaiah was court-martialed and imprisoned. While he was in prison, the government attempted to use his altered DNA to create another Super-Soldier. After 39 attempts they had a single success, which was Josiah. His surrogate mother smuggled him out from the government's watchful eye.

Josiah grew up alone in a Catholic orphanage outside of Boston. His powers revealed themselves when he lashed out at one of the orphanage nuns while in his early teens. Believing he had accidentally killed Sister Irenia, he fled. Under the assumed name of Josiah Smith he entered the U.S. Army.^{[volume & issue needed]}

Josiah served several tours in the Vietnam War, becoming a seasoned and experienced veteran. His unit, made up of primarily black soldiers, were nearly killed on a mission by an inconsiderate and racist officer's order to bomb the area while they were still on patrol. His assault on the heartless officer was rewarded with a court martial. Josiah was sent back to the States to serve out his sentence in Fort Leavenworth, a stateside military prison.^{[volume & issue needed]}

Blood tests at a secret research facility in Berkeley, California proved he was the missing Super-Soldier baby. His surrogate mother was brought in to confirm a genetic match, and she again helped him to escape. She also told him the truth about his past and the real first names of his genetic parents.^{[volume & issue needed]}

It was a long four years later before he could act on this knowledge. He came across a list of African-American individuals abused by the Super-Soldier project, and used it to find his parents' full names and their location.^{[volume & issue needed]}

After meeting his real parents, Josiah left the US and traveled abroad as a private military contractor and adventurer; he eventually ended up on the continent of Africa. It was in Africa that Josiah discovered the Islamic faith and decided to use it to find a purpose for his life.^{[volume & issue needed]}

Josiah became involved with James Rhodes' clandestine "Crew" after they were tricked into believing he was a criminal. After the usual superhero fight, Josiah joined them to seek out those who had not only framed him, but had also turned his neighborhood into a war zone.^{[volume & issue needed][96]}

When Iron Lad forms the Young Avengers, he attempts to recruit Josiah, but instead recruits his nephew Elijah Bradley when Josiah is unavailable.^[95]

Due to his unique genetic makeup, Josiah has aged very slowly. Although he is well over fifty years old, he appears to be twenty-five. His genetic code was manipulated with great precision to compensate for the side effects of unrefined Super Soldier serum. Josiah is extremely strong (able to bench press over 1100 pounds) and his body possesses phenomenal endurance. Because of his many years on the run from the U.S. government, Josiah has experience and training as both a soldier and mercenary. He also has decades of experience with a variety of martial arts styles, languages and weapons.

Josiah carries the scarred battle shield belonging to his father and predecessor Isaiah, similar to one used by Steve Rogers before receiving his vibranium-steel shield. It is an unpainted concave triangular metal shield with the Double V for Victory design. For protection he wears a loose chain mesh shirt over light padding.^{[volume & issue needed]} This mesh shirt is capable of blunting the impact of most small arms fire.

Joystick is a fictional character created by Marvel Comics. She is the villainous alter ego of Janice Yanizeski. She debuted in The Amazing Scarler-Spider #2 (December 1995), designed by artist Mark Bagley.

Joystick is a participant of "The Great Game", a competition between costumed individuals sponsored by wealthy executives. When she is first introduced, she presents her "monitor" with the mask of fellow participant El Toro Negro. She is assigned a match in New York against Scarlet Spider. Joystick goes to the Daily Bugle looking for reporter Ken Ellis. She meets Phil Urich (without his costume). Scarlet Spider follows Ellis and is ambushed by Joystick. Phil Urich (as Green Goblin) saves Ellis as Ben Reilly still fights the woman. Meanwhile, in Paris, El Toro Negro attacks Joystick's "monitor", seeking revenge against her.^[97]

Phil Urich, the heroic Green Goblin, develops something of a crush on Joystick, a participant of "The Great Game". He dons the costume and visits Joystick's hotel room, where a package is assigned to "Scarlet Spider". He opens it anyway and receives a dose of some kind of gas. Somewhere else, Joystick takes notice of the hotel room situation in her van and learns El Toro Negro is after her as payback for his defeat. Green Goblin is attacked by Joystick, until El Toro Negro surprises them. Scarlet Spider soon arrives to defeat El Toro Negro while Phil Urich saves Joystick. Scarlet Spider scolds the Green Goblin for letting her go.^[98]

She is later seen in the Return of Kaine arc of the Clone Saga, fighting again against Ben Reilly (then under the Spider-Man identity) and his clone Kaine, with Polestar. Ben Reilly jumps to defend Kaine and Muse against their assailants. Kaine defeats Rhino as Ben destroys Joystick's weapons and beats Polestar.^[99]

Later, she once again attacks Ben Reilly when he invades a facility's installations. Soon after, when Ben Reilly stops an attempt on Jonah Jameson's life (courtesy of El Toro Negro), an all-out brawl happens between the three and mercenaries Chance and Cardiac. During a fierce melee battle, El Toro Negro unveils his role in the conspiracy to a beaten Joystick: he assumed the role of a rogue player in the game to divert attention to the hostile takeovers happening backstage. Joystick confesses that, despite the false pretenses of El Toro Negro's role, she still defeated him and took his mask.^[100]

Joystick much later becomes a member of the New Thunderbolts.^[101]

Jumbo Carnation is a fictional character appearing in Marvel Comics, a mutant fashion guru who first appeared in New X-Men #134 (November 2002),^[102] created by writer Grant Morrison and artist Keron Grant. The character also died that issue; it is left unclear if the character died from a drug overdose or from a hate crime.^[103] The character was later resurrected during the Krakoan Age where he is a designer for many Krakoan mutants and suggests the first Hellfire Gala.^[103][104]

Justice Peace is a cyborg agent of the Time Variance Authority.^[105][106] During the Infinity Wars storyline, Gamora fuses her and Carol Danvers, creating Captain Peace.^[107]
