Wild Child

When Kyle Gibney's mutant powers began to emerge at an early age, he was left with a freakish appearance. Horrified, his parents kicked him out of his home, and he was left wandering the streets. Eventually found by the subversive organization, the Secret Empire, Gibney was experimented upon in their attempts to create a perfect killing machine. As a part of the experiment, Gibney was injected with DNA from the assassin Wyre, which left Gibney near-mindless, animalistic, and uncontrollable. Wyre later rebelled and destroyed the Secret Empire's headquarters.

Gibney was found by agents of the Canadian government and given over to Department H, then headed by James Hudson as a sanctioned program for developing Canada's superhero teams. Hudson placed Gibney in the entry-level Gamma Flight with the code-name Wild Child. (Like all recruits, those who developed their powers sufficiently would be placed in the premiere team, Alpha Flight.) During his training, Wild Child was mentored by Wolverine until he left to join the X-Men.

Unfortunately, the government disbanded the Department H program and, by extension, its hero teams. Gibney's subsequent activities remain unrevealed until Delphine Courtney and Jerry Jaxon recruited him for Omega Flight. Jaxon hoped to destroy Hudson and his Alpha Flight, which had reassembled as a private team, but Omega Flight was captured by Alpha Flight and its members imprisoned. Gibney managed to break out only once, and in his rampage, began killing indiscriminately. Nearly killing Heather Hudson, it took Wolverine to hunt him down and capture him again.

After resurrection, he would be tended and medicated by Dr. Reyes and Sage by old Weapon X medication, due to his feral mutation being problematic he was not allowed among the other Krakoans. Due to his mutation, he would always seek out an alpha to follow and if he could find it, he would attack them to see if they are worthy to be "pack leader", and until he found a worthy one, he would act feral and attack anyone he deemed either fit or unfit. Kyle pretended to sleep and to swallow his meds for the entirety of his stay, attacking both Dr. Reyes and Sage once they got close enough.

Due to this, Kyle was assigned by the Quiet Council to Mister Sinister's team of Hellions; composed of mutants who were too violent or troubled due to their mutation, led by Psylocke (Kwannon).

Their first mission led them to taking down the State Home For Foundlings in Omaha, Nebraska, which was a cover for Sinister's still active Marauders cloning farm. When Kyle and the Hellions arrived, they were confronted by and battled the Goblin Queen and her perverse Marauders, whom she had been magically torturing. After a swift defeat, most of the Hellions were captured, except for Kyle and Psylocke, who he had the urge to attack after believing she was faulting as the alpha. After his quick defeat and Psylocke cleansing his mind of his feral nature for the moment, Kyle was back to his more civilized self, speaking in coherent and complete sentences..

After Madelyne Pryor was shot dead by John Greycrow, Havok blew up the state home from anger, with Kyle and the Hellions escaping safe outside. After returning to Krakoa, Kyle was seen following Psylocke around, accepting her as his alpha
