First Aid is an Autobot medical doctor after Ratchet passed away and is the member of the emergency Autobots called Protectobots . He transforms into a Toyota Hiace ambulance and forms the left arm of Defensor. First Aid is devoted to helping and saving humans and Autobots' life. He hates to see any machine, whether living or non-living, suffer even the slightest.
First Aid is an devoted pacifist. When the Insecticons attacked an inhabited city on Earth, Optimus Prime called upon the Protectobots to evacuate the civilians caught in the crossfire. First Aid helped an injured man discovered by Streetwise. Later, as Earth's orbit was diverted to the Sun by the Combaticons, First Aid brought civilians to a meat locker that Groove and Streetwise had commandeered to help the humans cool down.
First Aid, as part of Defensor, was the arm that wielded the rifle which totally blew up Bruticus. Afterwards, he was with the Protectobots when they saved some window-washers from a burning skyscraper. Later still, First Aid and the other Protectobots were ordered to help defend Autobot Headquarters from a Decepticon attack. They merged into Defensor and activated his useless force field, which almost immediately deactivated, allowing the Decepticons to blast Defensor back into his component parts.
