Peter Pettigrew, known as "Wormtail", attended Hogwarts and was sorted in Gryffindor. Growing up he was friends with James Potter, Sirius Black, and Remus Lupin. He was a member of the original Order Of Phoenix. In truth, he was a double agent for Voldemort. While working for the Dark Lord, he gave the location of the Potters to his master, the Dark Lord, resulting in the deaths of Lily Potter and James Potter. He was known to be cowardly and begged for his life in Harry Potter and the Prisoner of Azkaban. He brought Lord Voldemort back to life by taking Tom Riddle Sr.'s bones, sliced his own hand off and sliced Harry Potter's arm to get blood on the graveyard. Voldemort gave Wormtail a magical hand as a thanks for getting his body back. This hand was much more powerful than Wormtail's original hand.
