9. The Creeper

(The Creeper, DC Comics)

Jack Ryder was a Gotham City news reporter who specialized in aggressive and argumentative practices to rile up his guests.

While reporting on nanotech specialist Dr. Vincent Yatz, he was caught trying to steal some of the doctor's regeneration tech for safekeeping, and was abducted by mobsters. In an attempt to keep his research safe, the Doctor injected his last sample into Ryder to keep it out of the mobsters' hands. The mobsters then gunned Jack down. But the nano tech brought him back as the bouncing and psychotic Creeper. Creeper fought crime solo in Gotham before he met and teamed up with Batman as they pursued the Hellgrammite.

Creeper had the ability to shift back and forth between his villainous identity and his real life as Jack Ryder. Also, Creeper's origin was revised like three separate times, and now he's maybe a demon or something? I dunno, it's complicated. But, hey, a news provocateur who's also a crazed superhero!

A pretty neat concept.
