Carnage

Of all Spider-MAn's foes, Carnage is perhaps the most dangerous, the most feared!
Criminal Cletus Kasady shared a prison cell with Eddie Brock, (better known as the
Lethal Protector, Venom)--that is, until Brock's symbiote freed it's human host.
However, Venom left behind a fragment of his alien costume, which bonded with
Kasady--creating the sinister menace known as Carnage!
