Bumblebee

Bumblebee is a quiet and a very playful Autobot. He hardly bothers his teammates, and even his human friends look up to him. Despite his nice demeanor, Bee holds a burden in him, due to Megatron ripping out his voice box during his time back on Cybertron. Bumblebee doesn't realize that he doesn't have to prove anything to his teammates, and that they all see him as a valuable member of the Autobots.
