Keegan-Michael Key on using his real voice to bring authenticity to B-127 in "Transformers One"

Keegan-Michael Key is stepping into the Transformers universe, lending his voice to B-127 in the upcoming film, "Transformers One," an origin story of Optimus Prime and Megatron. 

The highly anticipated film, distributed by Paramount Pictures, tells the story of how the two legendary characters were once friends before becoming bitter enemies. Key's character, B-127, joins forces with Elita, voiced by Scarlett Johansson, in a quest to save their planet billions of years before humans existed.

The voice of B-127, a younger version of the iconic Bumblebee, is very distinct. Despite sounding like it could have been computer synthesized, Key said the voice is 100% his.
