Jim is an only child who lives with his father Arther and his mother Connie. Before coming to the digital world he was a bit of a shy person, not having few friends, due to thinking it would not end well for him. Upon entering the digital world (against his will) he made an unlikely friend (and partner) with a dinosaur digimon called Gilamon. Jim, initially reserved beyond typical measures, eventually began to have confidence in his abilities as a Chosen One. He is the Bearer of Courage, and the god he follows is Apollomon. When the Chosen Ones laid siege, alongside many gods such as Grandracmon, to Kresnimon's palace, Jim was sucked through a dimensional rift and sent back to Earth.
