Lizard (Marvel)

The Lizard is a lizard-like monster in the comic book series of Spider-Man. Originally, he was one of Peter Parker's college professors, Dr. Curt Connors. Connors became the Lizard after falling into a pit of quicksand, and believed to be dead. The chemicals which affected him were radioactive, and transformed his body and genetic information. He grew rough, scaly skin, obtained the ability to climb walls with speed, as well as superhuman strength. He is also uncontrolable and unstable due to Lizard's transformation.
