Carnage (voived by Scott Cleverdon) is one of Spider-Man's many enemies. He was once a madman named Cletus Kassidy, who went insane. After he was arrested, Kassidy became cell mates with Eddie Brock. One day, the symbionte reunited with Eddie brock and became Venom, but a small piece that reproduced bonded with Kassidy, and became Carnage. He has all the same skill as Spider-Man, and Venom, including the ability to morph his hands, and body into weapons, and grow new ones every time.
