Biography
Edwin is a doctor, but he is also, secretly, a serial killer. He was kidnapped by the Predators to another planet as part of a plan to hunt him and others in order to improve their hunting skills.

He had to join others who came at the same time to survive. He has no weapons except a scalpel. In time he likes being on the foreign planet and he cannot stop his killing instincts. That´s why, in time, he plans to kill the other members who become less and less.

He is stopped, however, by Royce who always mistrusted him for not being a murderer, so seemingly innocent, and yet being there on the planet with others who were murderers and therefore had what the Predators wanted, hunting skills.

Having immobilized him with poison Edwin intended to use on him, Royce later used him as part of a plan to kill a Super Predator and, for that purpose, he mined him with grenades so that the Predator would find him and turn him around. This causes their explosion when the Super Predator does that and the trap correspondingly succeeds. Still it only knocked him out. Royce and Isabell defeated him later with other tricks.
