The account of his origin given by the assassin known as Arcade has been unsubstantiated and may have been concocted to mislead and confuse his opponents for his own amusement.
According to Arcade he was the idle son of a Beverly Hills millionaire. When he became an adult, Arcade's father cancelled his allowance, to which he responded by killing him the next day with an explosion. Inheriting his father's wealth, Arcade turned his skills towards killing for hire. Accepting million-dollar contracts Arcade often spent more than his fee in constructing his apparatus of death known as Murder-World.
