I was watching and reading Avatar show and some fo its books. Something about the past reincarnation of Avatars like Kyoshi, Szeto and Yangchen make me annoyed as time passed. It maybe my bias.
But each caused so many problems that led to there successors cleaning up their mess. Even Aang the best of them seemed to focused on Benders, that non benders were like second Class citizens in Legend of Korra.
So I want a just write a novel Avatar last air bender or Legend of Korra.
Where MC has three templates one is Yogiri Takatou from Instant Death and Zenos (ゼノス, Zenosu ) is the main protagonist of The Brilliant Healer's New Life in the Shadows.
Thus he lives his life healing people until Avatar annoys him, thus him destroying either Kyoshi or Roku's whole reincarnation soul.
Is this idea cool?
