Bumblebee is one of Optimus Prime's most trusted lieutenants. Although he is not the strongest or most powerful of the Autobots, Bumblebee more than makes up for this with a bottomless well of luck, determination and bravery. He would gladly give his life to protect others and stop the Decepticons. Badly damaged in battle, Bumblebee lost the ability to speak verbally, though he can still communicate over inter-Autobot frequencies (in a fashion that seems somewhat akin to instant messaging, a usable but more distant and less personal means of interaction). He can also communicate with the Autobots' human allies and his friend, Sam Witwicky, by playing audio clips from popular media on his radio.
Bumblebee is a kind hearted Autobot however he display's rather childish attributes as shown when he urinated on Seymour Simmons to force the latter to reveal information even being told off by Optimus, as well as acting stroppy once being instructed to hide In Sam's garage. Despite this in most situations he acts serious on his missions keeping a level head within the group; it should be noted that Bumblebee has made friends with almost everyone on the team as he cares a great deal about his teammates whom in return see Bumblebee as a true friend who always has their backs.
Despite his young age, Bumblebee has proven to a skilled warrior though he lacks in strength he has been able to take down opponents such as Barricade, Rampage and even go toe to toe with Soundwave. In terms of weaponry, he is armed with a plasma cannon additionally he posses two rocket launchers stored on his back.
