Mr. Hammer and his brother Carl Hammet had competed their whole lives, each trying to outdo the other. Carl even changed one letter of his last name to separate himself. Their rivalry grew into a bitter hatred between the brothers. The final straw came when Hammer purchased a shadow suit and tried to kill Hammet. Vigilante intervened and was forced to kill Hammer in self-defense. Hammet later gloated to himself how he had arranged the circumstances of Hammer acquiring the shadow suit. He knew it would drive his brother mad and an assassination attempt would follow. Hammet had planned to use this opportunity to kill Hammer and claim self-defense. That the Vigilante had done it for him was all the better. Without his brother and competition, Hammet was free conduct his business freely, with a shadow suit of his own.
