Alter ego: Rouge.

Species: Mutant girl.

Rogue has the ability to absorb the life-force energy, personality, and memories of any person she touches. The people she absorbs life-force from will either lose consciousness or end up in a coma, depending on how much she drained from them. If she touches a person for too long, then she could kill them. A side effect of this ability is that Rogue retains a mental imprint of the person she absorbed.
Rogue can also absorb the powers of any mutant who she touches. However, this absorption is only temporary. ..
She is famous character in Marvel X-men.
