Bumblebee (AKA Bee, ZB-7, B-127) is the secondary protagonist and one of the deuteragonists (alongside Mikaela Banes, Carly Spencer, Tessa Yeager and Viviane Wembly) in the Transformers live-action film series and the titular protagonist of the 2018 Reboot/Spin-off film, Bumblebee. He 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. He is voiced by Erik Aadahl in The Last Knight and Dylan O'Brien in Bumblebee.
