Rogue & PoservsPoison & Ant

Rogue & Poser Poser copies any mutant; plus, is instantly a better wielder than the user she got the powers from and without the limitations that the normal user may have had. Plus, she retains any copied powers perpetually, if not forever. Rogue is the only mutant. So, you'd have Rogue and advanced Rogue in comparison to what Marie is...Ant has a protective armored skin that presumably voids Rogue's touching powers. Yet, they still must fight.

On Poser, Can you imagine if Copycat could be that advanced with her power to copy all powers?
