Steeljaw loves the feel of the wind whipping across his sensors as Leadfoot screams around a track. The cyber-dog is ill-tempered, rickety, and occasionally emits noxious fumes or sparks bad enough to set his surroundings on fire, but Leadfoot doesn't mind. Even the humans Leadfoot works with have learned to appreciate having a mean robot dog with a powerful bite around. Steeljaw is the Ulimate Tracker. When the Wreckers need to locate a Decepticon, creature, person or object, they turn to Steeljaw's advanced senses.
