1. Ron Perlman as Firelord Sozin

Golden Globe winner, Ron Perlman, isn’t a stranger when it comes to voice acting.

He starred in only one episode: "The Avatar and the Firelord." In the episode, Perlman provided the voice for Firelord Sozin.

You don’t have to be an actor to star in a famous animation series, at least not when your name is Serena Williams. The former #1 tennis player starred in both Avatar: The Last Airbender and The Legend of Korra. In the former, she voiced Ming, a Fire Nation soldier who guarded Iroh during his time in prison. In the latter, she gave her voice to a sage that helped Avatar Korra.

3. George Takei as a warden

10. And finally, Mark Hamill as Firelord Ozai

Disney, Nickelodeon

We saved the best for last, and that's Mark Hamill. Hamill, who everyone knows as Luke Skywalker in the Star Wars franchise, voiced the part of Firelord Ozai. With his part as Ozai, Hamill showed that he's not only able to portray a convincing good guy but also easily can turn to the dark side. And boy, he did one hell of a job!
