Mister Sinister

Mister Sinister is one of those villains who is long overdue. A human who became a mutate after encountering Apocalypse, Sinister is one of those supervillains who can appear all over the place in the X-Men universe. Because of his shape-shifting abilities, we wouldn’t even know he was there.
He has quite a few extraordinary powers, including telepathy, complete control over his body, an accelerated healing factor, and telekinesis. But, above all, he is a super-scientist, a sort of modern Frankenstein who tries to create the perfect being.
So he could be behind the Weapon X program, and he could be the perfect villain for Deadpool. As we know after seeing this year’s hit, the Merc with a Mouth has seemingly ended his career as a sort of superhero. With Vanessa in trouble, he could go on another mission, to discover who is behind his and his girlfriend’s new condition.
Knowing that Apocalypse arrives this year, knowing that next year Gambit might introduce Sinister, and knowing that Bryan Cranston teased this particular character…well, you can do the math.
