Ratchet

Ratchet, the Autobots' medic, is probably the bravest of them all. He'll risk his life to pull any wounded comrade from the battlefield. Indeed, he did not join Optimus Prime's team to be a soldier; rather, he's there to save lives, and thinks Prime is the best chance the universe has for peace.

A medic who dislikes violence, Ratchet's well-armed appearance is more due to being an improviser with surgical tools, such as his buzzsaw, which he discovered he had a penchant for due to his early experiences as a tool-and-die maker. When combat is unavoidable, he can employ these makeshift weapons with surprising agility for his size. Years of being at the heart of the war have gradually acclimated Ratchet to the heat of battle. He's taken on the likes of the Decepticons' toughest warriors and is always throwing himself into the midst of the fighting, if it means he gets to defend his fellow Autobots and help save the day. Nonetheless, he remains one of the most genuinely kind members of the Autobots, valuing their friendship and camaraderie above all else, and would never betray their trust. He may not be the strongest Autobot, but damned if he's not one of the most dependable.

His closest comrade is Arcee, and they share a common enemy in Lockdown.
