Shin Megami Tensei: Synchronicity Prologue
J is the transformed consciousness of the programmer Jones, who was the first test subject of the Synchronization project. He fell into a coma while his mind took the form of an overweight animal man. Black Frost, who he attempted to synchronize with, went berserk, causing other demons who synchronized with him to go mad as well. He is hunted down by Bifrons, who is stopped by Subject Two's synchronized Jack Frost and Jack o' Lantern.
In the normal ending, he dies upon Black Frost's defeat at the synchronized duo's hands, causing his comatose body to die as well. In the best ending, the news reports that he awakens from his coma.
