Bumblebee

Bumblebee is a young and eager Autobot, 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 the 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.

Earth was a far cry from the ravaged wasteland of his birth, but Bumblebee adapted to his new home much faster than any of his fellow Autobots. He's grown to like and understand Humans, particularly Spike Witwicky, Sparkplug and Carly Spencer. In befriending the natives, Bumblebee also developed a love for Human culture, be it the historical exploits of Earth's cowboys or cheesy hair-metal bands. In some ways, he considers the planet to be his adopted homeworld.
