Bumblebee is the Autobot scout and is always trying to prove himself worthy of being a warrior. He joined Optimus' team of Autobots during the sacking of Iacon after volunteering to be a messenger to tell him the news of Omega Supreme's defeat and Sentinel Prime's death. Notable adventures during the War for Cybertron include him helping re-establish communication with the rest of the city, joining Optimus in an attempt to save Sentinel before death, and helping to take down the mighty Decepticon titan Trypticon. During the battle of Tyger Pax, he lost his voice after Megatron crushed his voice box and left him for scrap until Ratchet restored him as best as he could. However, throughout the entirety of the show, Bumblebee is mute, only able to speak through bleeps and boops.

Goldfire is a reborn Bumblebee after being killed by Megatron at the end of the series and put into cyber matter from the Decepticon's Omega lock replica. Now with his voice box restored and an upgraded form from his original Cybertronian mode after killing the Decepticon warlord, not to mention an electric gold paint scheme, Bumblebee has officially become the warrior he was always meant to be, and he takes his new name Goldfire with pride, trying to live up to the expectations that Optimus Prime has put upon him.

Goldfire/Bumblebee needs to sound similar to Will Friedle's interpretation of Bumblebee in the last episode or like Rodimus Prime, provided by Judd Nelson. But for a prequel series, before he loses his voice, he needs to sound similar to Johnny Young Bosch's interpretation of the character, as he sounds a bit younger and eager.
