Steeljaw is an Autobot Deployer under the command of Blaster with a powerful bite. He's ill-tempered, rickety, and occasionally emits noxious fumes or sparks bad enough to set his surroundings on fire. Any relation to the Decepticon leader of the same name is currently unknown at this point.
Steeljaw appears in the Rise of the Dark Spark game for Nintendo 3DS as a support unit. Equipping him allows all Cybertron Autobots to take initiative in head-to-head melee combat.
