Brandon Heat
A small-time criminal who was in a gang with his best friend, Harry McDowell, along with three other close friends. After their friends were killed, Brandon and Harry joined the crime syndicate Millennion, led by Big Daddy. Brandon was trained by Millennion's Bear Walken to be a sweeper (assassin), eventually forming his own elite sweeper unit within Millennion called "True Grave".
As Harry rose to power, Brandon remained loyal to the syndicate. Brandon confronted Harry for betraying the organization, but found himself unable to kill his friend. Instead, Harry killed Brandon. Brandon was resurrected by Dr. Tokioka as "Beyond the Grave". His purpose is to destroy the syndicate that he once worked for and the friend who betrayed him.
Harry MacDowell
"Bloody Harry" was the leader of small-time gang operating out of Desolation Alley and Brandon's best friend. After five years with Millennion, the two friends were made part of the leader's inner circle. As part of Big Daddy's "family", they were expected to follow a strict code of conduct, but Harry took the code lightly. He started killing and cheating his way to the top of Millennion, ultimately securing his position by killing his best friend.
