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.
