James Potter, also known as Prongs, was a pure-blood wizard. He attended Hogwarts School of Witchcraft and Wizardry, and was sorted into Gryffindor house. There he became best friends with Sirius Black, Remus Lupin, and Peter Pettigrew; together they created the Marauder's Map. Also during this time, James played Seeker for his house's Quidditch team.
He worked alongside his enemy Severus Snape at Horace Slughorn's shop, and constantly threw Snape in the dumpster out back for doing things like make him work late on Christmas Eve, and talking to his then-girlfriend Lily Evans.
Tragically, James and Lily were betrayed by one of their friends, Peter Pettigrew, to Lord Voldemort. James was murdered by Voldemort, along with his wife, while they were trying to protect their son, Harry.
