Peter Pettigrew

Peter Pettigrew, O.M. (Third Class), (c. 1960 – March, 1998), also known by his nickname "Wormtail,"[9] was a wizard and son of Mr and Mrs Pettigrew. He began attending Hogwarts School of Witchcraft and Wizardry in 1971 and was sorted into Gryffindor House after the Sorting Hat pondered over which house he belonged in for over five minutes, a true Hatstall. During his years at Hogwarts, he became one of the Marauders; he was best friends with Sirius Black, James Potter, and Remus Lupin, and together they created the Marauder's Map.

During the First Wizarding War, Peter was a member of the Order of the Phoenix, but became a spy when he defected to Lord Voldemort. He was made Secret-Keeper for the Potters when they went into hiding with the use of the Fidelius Charm, and betrayed James, his wife Lily, and their son Harry to Lord Voldemort. After Voldemort's fall, he faked his own death and framed Sirius for betraying James and Lily, as well as for his own murder and those of the twelve Muggles he killed during his escape.

Peter spent twelve years living in his Animagus form as the Weasley family's pet rat, Scabbers.[9] However, his identity was exposed by Sirius and Remus in 1994, and Pettigrew, with nowhere else to go, sought protection in returning to the service of Lord Voldemort, whom he found in the forests of Albania.

Pettigrew played a key role in Voldemort's rebirth and continued to serve him during the Second Wizarding War. In the spring of 1998, during the Skirmish at Malfoy Manor, Wormtail was killed by a beam cast by Dobby.
