Siphon abilities

Power drain, energy drain, or life-force drain? Aside from copying powers, I can't think of such a thing as "power draining."

Think Rogue or Parasite

The ability to absorb other peoples memories, life-force, abilities and even powers.

Case Closed

" Think Rogue or Parasite "

mmmmmmhmmmmm

Removing Mimic, Synch, Rogue, Copycat, what other characters can do it?
