He is voicing several characters on the Avengers Assemble animated series and Max Tennyson in the reboot of Ben 10. Kaye later moved to Los Angeles and has since worked on Ben 10: Omniverse as the villain Khyber, on Regular Show as Reginald, and on Xiaolin Chronicles as Clay Bailey, F-Bot, and Chase Young. His involvement in anime has led to several appearances at conventions. In anime, Kaye has been the voice behind Sesshomaru in the English dubbed InuYasha series, Treize Khushrenada in Mobile Suit Gundam Wing, Recoome in Dragon Ball Z (1996–98) and as Soun Tendo in Ranma ½. He also lent his voice to the later series Transformers: Prime and Transformers: Robots in Disguise. In 2007, Kaye become the first and (as of 2021) only actor in the franchise to play both Megatron and Optimus Prime in regular roles, voicing the latter for Cartoon Network's Transformers: Animated. This began a decades-long relationship with the Transformers franchise. During this time, he was cast in several animation shows and video games, including a role as Megatron in Beast Wars. On-camera opportunities came in the form of guest roles on TV series and movies such as The X-Files, Battlestar Galactica, and Happy Gilmore. Working as an on-air talent for radio station CKLG ( LG73), he quickly became less interested as both on-camera and voice roles started taking up more of his time. Kaye's voice acting career began in 1989 with General Hawk in the DiC animated series G.I. He also did theater, playing George in a production of Who's Afraid of Virginia Woolf and Elwood P. During the 1980s, Kaye moved to Vancouver to work in radio.
