Bud is a fictional character in the Transformers: Cybertron (called Transformers: Galaxy Force in Japan) cartoon series. He is normally voiced by Ryan Hirakida in Cybertron, although in some episodes his voice was performed by another actor. He is voiced by Nami Kurokawa in Galaxy Force.

Bud is a pre-teen boy who lives in Colorado. Along with their friend Lori, he and his older brother Coby befriended the Autobots after finding and aiding the damaged Landmine. Bud is a very imaginative boy, and a big fan of science fiction television shows and ninja movies. Bud and Coby have an older brother named Tim.

Unlike Coby, Bud enjoys horror movies and has on occasion teased his brother about it. While rather independent, Bud has on occasion been grateful for his older brother's presence. He is also quite jealous that Coby now pilots a Scrapmetal drone.



Towards the end of the series, Vector Prime gives Bud his space map as a keepsake as he prepares to sacrifice himself to help the Autobots return to Cybertron so that they may face the Decepticons. In the finale, Bud in turn gives the map to Galaxy Convoy and makes him promise to come back safe and return it personally.

During the epilogue montage, Bud is shown as an adult, having apparently become a very successful actor or director. The final scene of the series has him standing with his family, Optimus, and the Mini-Cons, celebrating Coby and Lori's wedding.
