Avatar: The Violet Dragon

Michael was a normal 15 year old high schooler but suffered an unfortunate death. Being one of a lucky few, he was able to reincarnate into the world of Avatar: The Last Airbender, as the son of a Fire Nation general during the Hundred Year War. Friends with Zuko, Michael, now called Zokai, The Violet Dragon, joins him and his Uncle Iroh on their search for the Avatar.
