In some other alternate universe right now, someone is sitting in a theater, watching Deadpool fight Garrison Kane on the big screen. Stab my eyes that we don't live in that universe.
Yes, according to screenwriter Rhett Reese, instead of just Ajax and Angel Dust, we were originally going to have three characters under Ajax.
"We consolidated, in the first draft, Ajax has really three underlings. It was Wyre, it was Garrison Kane and it was Sluggo," Reese revealed to CinemaBlend. "And then ultimately due to budget, we had to consolidate those into one character. And we wanted the movie to have a really strong kick-ass female presence. That was a mandate from Tim, so we introduced, we introduced Angel Dust as sort of a combination of those three to provide the muscle for Ajax."
Wyre was a mutant assassin with pointy spines and tendrils. Sluggo was a Weapon X graduate who was big, a mercenary, and invulnerable (so pretty useful in a fight). Garrison Kane is the one of the three that broke out a bit, another Weapon X grad, he was a cyborg mercenary - almost a combination of Deadpool and his pal Cable (minus the added mutant powers of the latter).
For now, we get Gina Carano doing a superhero landing and punching Colossus hard enough to make him look like a punk, and that's pretty cool, too. It'd be cool to see the Weapon X program continue to expand in future flicks.
