Bumblebee

"I wish to stay with the boy."
- Bumblebee to Optimus Prime after forming a strong friendship with Sam Witwicky.

Bumblebee is one of Optimus Prime's most trusted lieutenants. Sent to Earth ahead of the other Autobots to gather information about the AllSpark while keeping himself hidden. He usually works best in silence and solitude, and while he is nowhere as strong as other Autobots, he makes it up by his determination, bravery and ridiculous amount of luck.
