Bio
Bumblebee is a young and eager Autobot, a member of the last generation to be created before the loss of the AllSpark. He's full of energy and determination to do the right thing, and can always be counted on to volunteer for action. His small size, matched with his impressive speed, made him an excellent scout and messenger on war-torn Cybertron. Grievously injured and rendered mute by Megatron during the war for Cybertron, Bumblebee was haunted by the loss of his voice box for many years, creating a ruthless streak at odds with his otherwise friendly personality. Determined to prove himself, Bumblebee kept fighting even after the Transformers' age-old war spilled over to Earth.
