STRONG ARM would rather work than fight, just like his friend SIGNAL FLARE. He is an electronics and physics genius who builds weapons and other gear for the AUTOBOTS. Good natured and friendly, he always has a joke for any situation, and keeps up a constant stream of conversation while he works, either with other robots in the room, or with his voice-activated computer.
