Couldnt find the old thread sorry.
So it looks LIKE Xforce is
Deadpool
Domino
Negasonic
Bedlam
Cable(When he stops trying to kill the boy)
The rest is rumor or speculation
Shatter star
Pete wisdom
Rictor(played by pennywise)
Colossus
Also didn't see him in the trailer but Black Tom is listed on the IMDB page so maybe he's the real villain.
When they get off that the chopper is that the Cab driver in the back right wearing yellow?
