Captain Avatar and The Avateers

Looting and Polluting is not the way, Zuko!

Based on a running fandom joke, Captain Avatar is a series of interconnected comment fics written by suzukiblu on LiveJournal that places the characters from Avatar: The Last Airbender into the roles of the Planeteers from Captain Planet. There are just under fifty commentfics written for the universe.

Your Cheating Heart: Yue has a fiancé and a boyfriend, and then there's Zuko, sleeping with both Mai and Jet. Then they catch him.
