Bumblebee is one of Optimus Prime's most trusted lieutenants. Although he is not the strongest or most powerful of the Autobots, Bumblebee more than makes up for this with a bottomless well of luck, determination and bravery. He would gladly give his life to protect others and stop the Decepticons.
Badly damaged in battle, Bumblebee lost the ability to speak verbally, though he can still communicate over inter-Autobot frequencies (in a fashion that seems somewhat akin to instant messaging, a usable but more distant and less personal means of interaction).
War for CybertronEdit
Bumblebee fought for Optimus against Megatron and launched the AllSpark into space, but not before Megatron crushed his vocal processors.
Bumblebee became Sam Witwicky's first car, turning into a Camaro. He fought alongside the other Autobots in Mission City.
Revenge of the FallenEdit
Bumblebee participated in the second Earth battle against the Decepticons and killed Rampage.
Bumblebee met up with Pohatu at the beginning of the war and fought hundreds of inbred Skrall before being blasted off back to Cybertron by the Mask of Lifes last muster of energy.
