Kai Hans a.k.a My Deadpool Sona (it's me!)
Kai is also actually a mutant, his mutation allows him to sense wavelengths in the air - this includes other colours normal humans can't see, sounds that only dogs can hear and things like radio signals. He has to concentrate to tune into them, but he used to hear all of them all at once. He can also broadcast his own thoughts across radio waves.
The same story as the original Deadpool - Kai got cancer found "Ajax" thought he thought could help and got fucked up. But unlike Wade, he killed Francis the first time during that fight in the fire.
After that, he just continued to take on odd jobs but after the experimentation his mind was compromised, and he has episodes that make him go temporarily insane. (Kinda like when Wolverine goes berserk). And then he was hunted down by the FBI for being too dangerous because the X-Men were protecting him.
He actually is an X-Man (he was picked up by Xavier when his mutation developed but went off on his own after he "graduated") but he stray's sometimes and is more of an associate technically.
He dated Kurt for a while but it didn't work out and there were no hard feelings. Him and Logan on the other hand wasn't unexpected but was very rocky in the beginning.
(This backstory was whipped up really quickly so idk how I feel about it)
