James Sirius Potter (b. 17 April, 2004) was a half-blood wizard who began school at Hogwarts School of Witchcraft and Wizardry in 2015, and was sorted into Gryffindor.He was the eldest child of Harry and Ginny Potter. His godparents were his uncle and aunt Ron and Hermione Weasley. He has two younger siblings: Albus and Lily. James was named after his paternal grandfather, James Potter, and his father's godfather, Sirius Black.
James was seen going to Hogwarts on 1 September, 2017 with his brother Albus, who was just starting his first year. James, being the oldest child, had already been attending Hogwarts, but it is not specified which year he was entering. Contemporaries at school include his cousins Victoire and Rose, as well as Draco Malfoy's son Scorpius, though they are in different years.
When his family was gathered to see him and his brother off at King's Cross Station on 1 September, 2017, James interrupted his cousin Victoire snogging Teddy Lupin, and then ran off to tell his family and other relatives. He was disappointed when they did not react strongly.
In 2017, James also stole the Marauder's Map from his father's desk drawer.First yearJames Potter was in the School of Witchcraft and Wizardry Hogwarts in 2016 and was selected to be in Gryffindor. This year he made friends with Ralph Dolohov and Jason Jordan, and also managed to join the group of pranksters and criminals who prowl the night of Hogwarts called Gremlins. James also tried to be chosen for the Gryffindor Quidditch team, but failed to do what Ethan Humberstone called "the flight lunatic and suicidal on the broom."
