An super-villain, and enemy of the Justice League.
Parasite has the ability to absorb the energy, abilities, and powers of others, particularly superheroes. Although he has an anthropoid layout (head, body, two arms, two legs) his appearance is very alien-like with an overall purple coloring and white details. He has to make physical contact with his victims which he does by shooting long feelers or tentacles from his abdomen.
