Although it is not yet clear which villain Kesy will play, there are rumours of him being Black Tom, Digital Spy.
Black Tom appears in comics as a general enemy of the X- Men and has battled Deadpool several times. Originating in Dublin, he has a unique relationship with plant life, being able to use it to project energy.
Ryan Reynolds will return in the sequel as the foul- mouthed superhero with Josh Brolin recently having signed on as Cable. The film is in pre-production with shooting expected to start in June.
