DC Comics (Pre-New 52)

Creeper

Jack Ryder, a TV show host known for his aggressive and outspoken style, has two origins as the Creeper. In the first, while infiltrating a costume party of gangsters who kidnapped Dr. Yatz, Ryder is stabbed and receives a serum granting superhuman powers and a healing factor, along with a molecular transmuter that alters his appearance to access these abilities. In the second, at Yatz’s lab pursuing a story, Ryder is injected with nanocell technology before being fatally shot, transforming him into a yellow-skinned humanoid who defeats the mobsters. In both cases, he becomes the vigilante Creeper, terrorizing Gotham criminals and beyond. His origin remains unchanged after Crisis on Infinite Earths, making all pre- and post-event feats canon.
