Re: Villains You'd Like to See Return...?
Clicked on 'Agent X' thinking "did he cameo somewhere?". I think you meant Agent Zero. Agent X is a character similar to Deadpool.
Though the three villains I most want to see return are Sabretooth (Liev's version definitely), Lady Deathstrike and Toad.
Lady Luck is smiling at me. She knows something I don't.
