Kyle Gibney is a mutant who manifested a feral mutation during puberty; this mutation granted him enhanced physical abilities and an increased rate of regeneration. He also gains a bestial appearance, which prompts his parents to throw him out of their house. Living on the streets, he is kidnapped by the conspiratorial Secret Empire and subjected to experimentation that alters his mind and body and makes him mentally unstable and prone to violent and animalistic behavior. During this time, he becomes acquainted with Dr. Valerie Cooper, a United States government official who is unaware of the Secret Empire's true nature or activities. He is freed by Wyre, the man who has unwittingly been the source for the genetic material that is used in the Empire's experiments.
Gibney (now Wild Child) is detained by the military and given over to the custody of Canada's secret Department H, who oversees the formative Alpha Flight team. The Flight member Walter Langkowski, wanting to protect the youth from the military, places him in the trainee team dubbed Gamma Flight. After Alpha Flight and its trainee groups are officially disbanded, Gibney is recruited to join the first Omega Flight team, a group of professional criminals. Alongside Omega Flight, he battles Alpha Flight and is defeated.[4] Alongside Omega Flight, he battles Alpha Flight again in the West Edmonton Mall, and is defeated by Madison Jeffries.[5] Afterwards, he commits a series of murders, which ends when he battles and is captured by Wolverine after he severely injures and almost kills Alpha Flight member Heather Hudson.[6]
Wild Child is subsequently pardoned under unrevealed circumstances and given membership in the new Gamma Flight.[7] Alongside Gamma Flight, he battles Alpha Flight.[8] However, he then aids Gamma and Alpha Flight against Llan the Sorcerer's forces.[9] When Gamma Flight is disbanded soon after that, he goes berserk over his deprecated status and attacks Pathway, another trainee. Gamma's leader Nemesis teleport him away during a fight with Heather Hudson (then Guardian) and Wolverine, and he is captured by Wolverine.[10] Department H would later help him overcome his psychological problems and cure his mental illness, train him in unarmed combat, and place him as a special operative of the Canadian government assigned to Alpha Flight under the codename Weapon Omega. Alongside Alpha Flight, he battles Diablo.[11] He joins Alpha Flight's "Core Alpha",[12] meet the second X-Factor team,[13] and prevents the mind-controlled Omerta from assassinating Italy's head of state.[14] He also fights a Wild Child doppelganger during the Infinity War.[15] He is attacked by Wyre but rescued by Alpha Flight.[16] He searches for Nemesis, and is held prisoner with her by Rok, but they are then rescued by Weapon X.[17] He defeates Wyre in personal combat; he then learns about his true origin, and changes his codename to Wildheart.[18] He aids Alpha Flight in combat with the Wrecker.[19] He also becomes romantically involved with his teammate Aurora.[volume & issue needed]
His appearance eventually deteriorates back to his initial feral form, which prompts him to leave Alpha Flight and Aurora. He follows Valerie Cooper to the United States, where he joins the government operated team X-Factor. There he begins a romantic relationship with his teammate Shard. His teammate Sabretooth frequently attempts, with little success, to convince Wild Child to become a hunter and killer like himself. He remains with the team until his body begins to mutate into a more feral form. He eventually degenerates to a near-mindless state and is recruited into the new Weapon X team.[volume & issue needed]
As part of his draft, Wild Child is paired with Sabretooth to try and recruit Sunfire to the program. However, he refuses and badly burns Sabretooth. When Wild Child mocks his burns, Sabretooth slits his vocal cords and threatens to kill any Weapon X medical staff who would operate on him, making sure that he would remain mute.[20]
His past flame, Aurora, is also recruited into the team but she is not herself. After the Weapon X upgrades she becomes cocky and aloof, snubbing the ugly Wild Child and even engaging in a relationship with the horribly disfigured Director of the program. This becomes fuel for the fire when Brent Jackson attempts to undermine the authority of director Malcolm Colcord. Using Aurora's attitude toward him as motive, Jackson convinces Wild Child to join his splinter group.[volume & issue needed]
Decimation
Wild Child was seen on a terminal screen as one of the mutants depowered after M-Day.[21] His energy signature was found within the entity known as The Collective, along with the energy signatures of many other depowered mutants.[22]
Post-Decimation
Wild Child recently demonstrated that his powers had returned as well as previously erased memories. He even managed to best Wolverine in a quick fight. He is now looking like his old Wildheart persona.[23]
Wild Child appeared once more in conflict with Wolverine aiding Omega Red and attempting to kill Logan. He was doing so under the order of the enigmatic Romulus. His plan consisted of dropping Logan into molten steel; however, he was interrupted by Omega Red. While Wild Child and Omega Red battled each other, Logan managed to flee. Omega Red succeeded in distracting Wild Child and thus was able to impale him on his coils before throwing him into a vat of molten steel.[24]
Dawn of X
In the new status quo for mutants post House of X and Powers of X, Professor X and Magneto invite all mutants to live on Krakoa and welcome even former enemies into their fold.[25] Kyle Gibney joins a loose group of outcast mutants, operating under Mister Sinister: the Hellions, which also comprise Havok, Kwannon, Empath, John Greycrow, Nanny, and Orphan Maker.[26]
Powers and abilities
Kyle Gibney is a mutant who was experimented upon, genetically engineered by Secret Empire scientists using DNA replicated from Wyre. He has superhumanly acute senses, as well as superhuman speed, agility, reflexes, coordination, balance, and endurance. His teeth and nails are hardened and strong enough to rend substances as thick as bone. His body heals at a rate several times greater than that of a normal human being but not at the rate of Sabretooth's healing factor. He also has various animal-like mutations common for "feral" mutants: leaf-shaped ears; eyes with neither pupils nor irises; sharper-than-normal teeth with pronounced, fang-like canines; and elongated fingernails and toenails which can be used as claw-like weapons, as well as his hunched body posture. He is an excellent hand-to-hand combatant with both special ops and martial arts training from Wolverine as well as the Canadian government's superhero Flight program, and is also trained in acrobatics and gymnastics. In his bestial rages, he relies more on sheer ferocity than fighting skill. As Wildheart, the savage, bestial side of his personality was suppressed by an unknown drug, but his savage self still threatened to overwhelm his sanity at all times.
As a result of injuries suffered at the hands of Sabretooth, who prevented him from getting medical treatment, Wildchild was mute for a time. However, along with his renewed powers, he seems to have regained the ability to speak as well.
Reception
In 2014, Entertainment Weekly ranked Wild Child 93rd in their "Let's rank every X-Man ever" list.[27]
Other versions
Age of Apocalypse
In the Age of Apocalypse alternate timeline, Wild Child was a member of the X-Men and was frequently partnered with Sabretooth.[28] Wild Child possessed a low level of intelligence (comparable to that of a dog) and an inability to communicate verbally. As such, he was kept on a chain leash to prevent him from harming any of the X-Men. For a time, he was Sabretooth's sidekick, as Creed had rescued Wild Child from being a prisoner of Apocalypse's son Holocaust but his current fate is unknown. The 2005 Handbook to the Age of Apocalypse states that Kyle is away on a secret mission with the other X-Men who were not present during the Age of Apocalypse 10th Anniversary Limited Series, though when Sabretooth and Blink revisited their home reality during a mission as Exiles, Magneto and Rogue revealed to them that Kyle had run away after Victor and Clarice had disappeared when they were taken away by the Tallus. He was eventually found and claimed by Quentin Quire. He then moved to the latter's reality to replace its deceased Wild Child, who was not supposed to have died.[29]
Wild Child has since been returned to the Age of Apocalypse timeline as he is seen following and later confronting the X-Force.[30] He is killed while, along with the X-Men from his world and X-Force, trying to stop Archangel's genocidal plans on Earth-616.[31]
