From left to right:

Tar: Similar to Ooze, but the main difference being he has a thicker consistency, and this unlike him, does not require a suit to hold him together. It also means he has better control over shifting his body into different shapes, and can create chains of himself to get around. He is still limited by his original mass however, and had the same two 'cores' like Ooze, that if separated, will kill him.

SKULLFACE: Okay he doesn't call himself that. Ooze and Chemical Man call him that. As implied by the Eden prequel comic he has some history with Chemical Man. He has many 'cores' in his body, and can control separated parts of himself independently from each other. Which he places in robots to act as his minions.

Justin: A spoiled brat whose latent mutant has resulted in him developing hypnotic powers. Not so much of a villain as much as a nuisance. Still, he consistently tries to get whatever he wants using his powers, and often gets away using others as scapegoats.
