Bumblebee is an Autobot warrior and the former scout of Team Prime as well as the guardian of his human friend, Raf Esquivel, in Transformers: Prime . Bumblebee was a very important member of Optimus' team during the Great War and was with Optimus for the longest out of any Autobot, excluding Ratchet. Bumblebee went with Optimus, Bulkhead and Ratchet to Earth in an attempt to stop the Decepticons from draining the planet's energy and taking it over. At the end of the war, Bumblebee was the one to kill Megatron, the very same Transformer who took away his voice since the war. However, Megatron was revived by Unicron shortly after, who used his body as a vessel to attack Cybertron. With Optimus missing in action at the time and Ultra Magnus badly wounded, Bumblebee became temporary leader of the Autobots. Optimus returned and defeated Unicron with the help of his team. Before Optimus became one with Primus, Bumblebee promised Optimus that they will keep the peace in his memory before Optimus left. Optimus gave a last smile to them before going into the Core. When the Sparks burst from the Well, the team watched as the sparks fly out to bring life to their home again, including Optimus' own spark.
Years after the war finished, Bumblebee became a high ranking police officer, but was still praised as a war hero, with a partner Strongarm, but he began to see visions of Optimus leading him back to Earth with Strongarm, street punk Sideswipe and Mini-Con Fixit where they discover a crashed Decepticon ship with numerous fugitives at large. A dinobot named Grimlock, who was a prisoner on the ship, teams up with them as well as humans Denny Clay and his son Russell. Bumblebee currently leads his new team to hunt down the Decepticon fugitives on Earth. On some occasions, Bumblebee would mess up on his battle cries, which would make his team laugh or not impressed.
