1. Cable and Stryfe
Im putting Cable and Stryfe together in this one, because while Cable is the founder and leader of X-Force, Stryfe is his evil clone. Originally a total enigma when he arrived, it was later revealed that Cable was actually Nathan Christopher Summers, the son of Scott Summers (Cyclops) and Madelyne Pryor (a clone of Jean Grey). Infected with a techno-organic virus, a time traveller from the future told Cyclops the only way to save Nathan was by taking him to the future. There, Nathan grew up in a hellish world ruled by Apocalypse and became a freedom fighter. Nathan was cloned to preserve his body in case he couldnt be saved, but the virus spread was halted. Later, Apocalypses forces kidnapped the clone and Apocalypse raised him as his own son, naming him Stryfe. Growing up to be fierce opponents, when Stryfe travelled two thousand years through time to arrive in the present, Cable followed him. While Stryfe formed a terrorist organization called the Mutant Liberation Front, Cable became allied with the New Mutants and turned them into X-Force. Although typically seen with his helmet on, the revelation that Stryfe looked exactly like Cable led to speculation that Cable was actually leading the MLF
and X-Force. Armed with an arsenal of futuristic weaponry and powerful telepathic and telekinetic abilities, Cable is a powerful leader and has grown into one of Marvels most interesting characters. Putting him and Stryfe into the movie as the antagonists would make for a very entertaining flick. Although, the connection to Cyclops may be a bit too confusing for the casual viewers (its even too confusing for many comic fans), its best to just leave that connection ambiguous. Another alias Cable goes by is Nathan Dayspring, so just use that for his real name and only hint at the connection to the Summers clan as an Easter egg for the fans.
