Venom: Venom is Spider-Man's arch-nemesis. He is vicious and vengeful, and his only goal is to kill Spiderman. He has rows of disgusting teeth and a hideous scream. Eddie Brock became Venom after coming in contact with gooey, black alien substance.
Spider-Man 3
Things are just beginning to go well for Peter Parker. He has found the balance between being Spider-Man and having a life of his own, and he has won the girl of his dreams. Good times never last long for Peter, though, and even with three new powerful villains - Sandman, Venom, and the New Goblin (Peter's friend Harry, who turns on him after finding out that he is Spider-Man.) - his greatest battle is within himself.
