Gerard was one of the two big henchmen of Tennyson and the brother of Killeen, all of whom appear in The Kings of Clonmel.

He fought Horace Altman, who was under the alias of the Sunrise Warrior, in his second match. Horace had been drugged, and would soon have been killed if Will Treaty hadn't intervened by shooting an arrow in Gerard's arm, halting the match. Gerard's fate afterwards is unknown.
