I think it would be a great idea if Marvel gave back Agent Zeros mutant abilities. It is about time that he is promoted to a full fleged hero in the marvel universe. He has a great back-ground story full of heart-ache and pain. Managed to survive the legacy virus (not many mutants did until colossus sacraficed himself...or seemed to). No-one im the marvel universe had a mutant ability that directly attacks mutants who have healing powers, this is a great move and makes the healing powered mutant more vunerable thus creating a platform for Zero to me a more dominate figure.
This is my first post. not sure how it will go but ill be back on this topic as Agent Zero is my all-time favourite marvel character.
