In his Hogwarts years he was close friends with Sirius
Black, Remus Lupin and Peter Pettigrew also known as 'The Marauders', creators of the Marauders
Map. In his 5th year at Hogwarts he, Sirius and Peter learned how to become animagus (very advanced
magic) in order to accompany Remus on the night of the full moon when he transformed into a werewolf. Potter took the form of a large stag and aquired the nickname 'Prongs' while the others aquired diffrent nicknames to fit their animal of transformation; Sirius became Padfoot, Remus became Moony and Peter became Wormtail.
While in school he was a CHASER not a seeker for the Gryffindor Quidditch Team and was a known trouble maker who enjoyed picking on a slytherin by the name of Severus Snape who they later dubbed Snivellus and Trying to make passes on classmate
Lily Evan who until their 7th year at Hogwarts ignored and disliked James. Potter also had a habbit of messing up his already messy hair to give it that 'just-off-the-brook look'
He ended up marrying his red-headed classmate Lily Evans and together they had a son, Harry James Potter. James appointed his best friend, Sirius
Black, yong
Harry's godfather.
James (who was other wise un-employed) and
Lily were both active members of the Firts Order of the Pheonix so naturally they were prime targets for Voldemort so they went into hiding. After preforming a Fedilus Charm on their home in Godrics Hallow they appointed Sirius
Black their secret keeper but at the last moment
Black suggested they use Peter as secret keeper because Voldemort would never expect it. So under
Black's advice Peter became secret keeper, little did the Potters know Pettigrew was working for Voldemort so no more than a week after the charm was cast Pettigrew sold out the Potter's. On
Halloween(1981)night when
Harry was but one Voldemort invaded the hidden
home and killed both elder Potters. James died trying to protect his wife and son.
