Ratchet, the Autobots' medic, joined Optimus Prime's team as a healer, driven by his belief in peace. Though he dislikes combat, he's well-armed with repurposed surgical tools like his buzzsaw, which he uses skillfully due to his background as a tool-and-die maker. Not the strongest, but reliable and caring, Ratchet values friendship and loyalty above all. His bravery and dedication focus on saving lives rather than fighting, making him a vital member of the team.
