Since the late 1990s, Robin Atkin Downes has been involved in genre films and television series, either as a live-action actor or vocal presence. One of his earliest credits was as Byron on the science-fiction show "Babylon 5," a character that would he reprise in many episodes and even a made-for-TV film. This was followed by a slew of voice acting work, and by the end of the 2000s Downes had performed in such popular cartoons as "Avatar: The Last Airbender." He has also lent his vocal likeness to animated and CGI-heavy features such as 2009's "Transformers: Revenge of the Fallen."
