Original Show: Avatar: The Last Airbender
Played By: Mako, Greg Baldwin
The Pitch: The old dude's resumé is impeccable: He's a firebending master, a former crown prince, and a retired general. Though he's a major part of the Avatar—the one without the blue monsters—as an old hedonistic wise man in exile, you can't help but wonder what old boy was up to back in the day. The world needs to know what Iroh got into before he started doing as much tea tasting as skirt chasing. Hopefully the resulting show wouldn't be Nick appropriate.
