First Aid (Transformers)
First Aid is the name of several fictional characters in the Transformers series.
Transformers: Generation 1
First Aid is a doctor and hates seeing any machine in pain, even an overheated car. Compassionate to the injured, but also a great fighter. Carries double-barreled crystallizer cannon to internally weaken enemy structures. Combines with fellow Protectobots to form Defensor.
Animated series
First Aid first appeared in the U.S. Transformers television series in episode 63, "The Revenge of Bruticus" with no explanation as to where he or the other Protectobots came from.
After the death of Ratchet in The Transformers: The Movie, First Aid became the Autobots' chief physician.
His most prominent role was in episode #85, The Ultimate Weapon. In that episode, First Aid returned to Metroplex after fellow Protectobot Blades was shot down by the Decepticons. Since First Aid was the only Autobot inside Metroplex at the time, the Combaticon Swindle infiltrated Metroplex to steal his transformation cog. First Aid attempted to stop him, but was unsuccessful. Feeling guilty about his inability to stop Swindle, he resigned from the Autobots and went into seclusion. Meanwhile, the Decepticons used Metroplex's cog to revive Trypticon. To prevent the Decepticons from gaining the advantage, the Autobots managed to steal Trypticon's cog for Metroplex. However, due to the incompatibility of the cogs, both robots began to experience major glitches as they fought. Hot Spot had no choice but to track First Aid down and try to convince him to rejoin the Autobots. Being the only Autobot to understand Metroplex's systems, he agreed and returned to repair Metroplex. This allowed Metroplex to defeat Trypticon yet again, and First Aid rejoined the Autobots with renewed confidence.
