Repair crab


 * Repair crabs are Transformer technology in the Generation 2 portion of the Generation 1 continuity family.

Repair crabs aid in a Transformer's repair, scuttling over the surface of the body reactivating disabled components. The unnamed crab-shaped technology is attached by lengths of cable to much larger machinery.

Generation 2
After Optimus Prime is damaged severely in battle with Megatron, repair crabs work to restore his body.
