Firelord was Galactus' latest herald. He attacked the Agents of S.M.A.S.H. until he was knocked out. During that fight, Firelord mentioned that Terrax had failed Galactus and it is implied that Firelord used his fires on him. When Galactus plans to consume Ego the Living Planet, A-Bomb carried Firelord's body onto Galactus' ship. When Leader took over the weaponry, Firelord helps the Agents of S.M.A.S.H. take down Leader. After Hulk and Ego the Living Planet defeat Galactus, Firelord leads Galactus away where Hulk has them look for an uninhabited planet for Galactus to consume.
