Brandon Heat
A small-time criminal who was in a gang with his best friend, Harry McDowell, along with three other close friends. After these three were killed, Brandon and Harry joined Millennion, a powerful mafia-type organization formed by Big Daddy. Brandon was trained by the Millennion’s Bear Walken to be a sweeper (hitman), eventually forming his own elite sweeper unit within Millennion called True Grave. Even as Harry rose to power, Brandon remained loyal to Big Daddy for Maria’s sake.
In the first game (and the anime), his purpose is to destroy the Millennion syndicate that he had once worked for and the man who betrayed him.
When he eventually confronted Harry over treason against the organization, Harry killed him. Brandon was then resurrected by Dr. T and “Beyond the Grave” was born.
In the storyline of the videogame he actually survives the ordeal, killing Harry (who politely accepts his defeat after the destruction of all of his created monsters). With his mission complete, Grave chooses to stay with Mika as her permanent Guardian, although he must be returned to sleep to prevent his necrolized body from deteriorating.
