The Ultimate Weapon
Galvatron claims to have a new weapon which is capable of mass destruction which he uses as a threat to get what he wants. First Aid, a pacifist by nature, leaves his fellow Autobots after failing to stop Swindle from stealing Metroplex's transformation cog. First Aid is finally persuaded by Hot Spot to return, and he steals Trypticon's transformation cog and installs it in Metroplex. Rodimus realizes Galvatron is bluffing about the weapon or he would have already used it, and the Decepticons retreat.
