Bumblebee

Bumblebee is an Autobot warrior and former scout of Team Prime who played a significant role in the Great War alongside Optimus Prime. He was temporarily the leader of the Autobots while Optimus was missing and later became a high-ranking police officer. Bumblebee led a team to hunt down Decepticon fugitives on Earth and eventually found a crashed Decepticon ship with fugitives at large. He was born as one of the last generation of Transformers created from the Well of Allsparks and fought bravely during the war, even after his voice box was destroyed by Megatron. Bumblebee eventually joined Team Prime and traveled across the galaxy for millions of years until reaching Earth.
