Bumblebee is a fictional robot character appearing in the many continuities in the Transformers franchise. The character is a member of the Autobots, a group of sentient, self-configuring, modular extraterrestrial robotic lifeforms.
In the original line of toys and in the animated series, Bumblebee is a small yellow Volkswagen Beetle. In the live action movies, he has appeared as vehicles inspired by the Chevrolet American muscle cars – with the live-action film versions being a yellow Camaro with black racing stripes.
Bumblebee is the "little brother" of the heroic Autobots and a mascot, constantly striving to prove himself in the eyes of the other robots—especially his leader, Optimus Prime. This often causes him to take risks and put himself in danger. He is portrayed as a smart alec, a capable, reliable messenger and spy, and his small size allows him to go places that his larger commanders cannot.
