Bumblebee

Bumblebee is an Autobot scout'''. ''' Due to a battle injury, he is rendered effectively mute, and communicates through use of selected playback of radio and television signals. Though his original voice is restored at the end of the first Transformers film, he communicates solely through his radio in Revenge of the Fallen and alternates between his voice and his radio in Dark of the Moon. Bumblebee helps Thomas the tank engine, Twilight Sparkle, and their friends from Barricade and Frenzy.

He is also good friends with James and Rarity.
