Bestia Oscura
Dark Beast has since returned to the Morlock's Tunnels after the fall of Norman Osborn. He was able to capture the Lizard and began developing a means of enhancing the Lizard's control of the reptilian parts of the human brain in order to turn human beings into humanoid lizards. Dark Beast had been abducting victims of bullying or abuse from the streets, until the X-Men and Spider-Man found his base. Dark Beast locks Spider-Man out of the room and triggers the mutation in Gambit, Storm, Emma Frost and Wolverine, although Emma comes through the 'attack' unharmed as she is in her diamond form, giving her and Spider-Man time to escape Dark Beast's minions and release the Lizard to knock him out. Later the X-Men and Spider-Man reverse the process and take Dark Beast into custody.
