Savage Dragon #35

Brainiape causes Hellboy to do battle with The Dragon, and then summons a giant sea monster, which eats them both. Unaffected by the Vampire's bite, Cyberface is only restored to health after Abner Cadaver imbues him with the life force of those around him. Hellboy's government allies kill the sea monster, and the emerging Dragon impales Brainiape's brain with a knife, freeing Hellboy from his mental control.
