3. Parasite

Rudy Jones was a Pittsburgh janitor working in a branch of STAR Labs. And he would have been fine, if not for one thing: Darkseid got all nostalgic.

Darkseid was sitting around his big evil lair, and he got to thinking, “Hey, remember that pink dude? The absorb-y one. What was he called? PARASITE! Right, that guy! What ever happened to him? He was cool!” And so, he decided to make a new one.

He manipulated Jones into opening a toxic waste container and mutating himself into a monster capable of draining humans, and superhumans, of energy. He was first used as a living weapon for the Suicide Squad when they faced off against Firestorm, but eventually fell into his niche of fighting Superman. He also developed a horrible leech mouth with just an impossible amount of teeth.

This turned him into a literal horror nightmare that I don’t want to look at. Although occasionally his appearance changes, and he looks like a guy who blew a bubble gum bubble all over his face.
