Rim Fire is the son of the late Pin Fire, and the successor and inheritor of the AC Bullet Life. Like his father, Rim Fire is cold, cunning, and has made upgrades to his AC. Rim Fire is considered one of the most dangerous among the Ravens due to his growing mental instability. He has been hunting down other Ravens without any regard for which side they belong to, simply for the purpose of his vengeance. His AC, Bullet Life, is a tetrapod with a camo pattern, armed with machine guns everywhere.
