Lizardman

The Lizard, a.k.a. Curt Connors is a fictional character, a supervillain in the Marvel Comics Universe. He is an enemy of Spider-Man. The Lizard first appeared in The Amazing Spider-Man #6 (November 1963), and was created by Stan Lee and Steve Ditko. In 2009, the Lizard was named IGN's 62nd Greatest Comic Villain of All Time.

In the stories, Curt Connors was a genetic biologist who researched the ability of certain reptiles to regrow missing limbs, partially to find a way to regrow his own missing arm. After a test on himself, he transforms into a violent lizard monster. Though able to revert to his human form, he suffers occasional fits of his alter ego breaking free.

Connors was played by Dylan Baker in Spider-Man 2 and Spider-Man 3. Rhys Ifans portrays Dr. Curtis Connors and his Lizard alter ego as the main antagonist in The Amazing Spider-Man.
