Wilko Brenggar
Wilko Brenggar was a pirate and member of the Happy Blasters. Completely insane, he was recruited into the Happy Blasters after he was found randomly shooting Imperial personnel in a spaceport. A murderer with hundreds of deaths to his credit, Brenggar handled his guilt by believing in reincarnation. He believed that he had been an Imperial captain, an Ithorian scout and a slaver in past lives.[1]
