Not My Usual Fandoms But Hell - Tumblr Posts

Avatar AU where when Zuko got blasted by his dad, he got sent reallllly close to the spirit world. Monk Gyatso, hanging around because he wants to see Aang, comes across a boy almost entering the spirit world permanently and consoles him, and decides to stick around. Now Zuko is still banished, but he's got Iroh when he's awake and Gyatso when he's asleep to undo the brainwashing his dad did to him, and it changes a few things.

One of them being that his fire bending style starts to utilize air bending moves, which is very confusing for Aang when they first meet.
