Kai (LEGO Ninjago, seasons 8-12)

Kai is one of the main 6 ninja of . He is the red ninja of fire, and Nya, the master of water's older brother. Unfortunately, during Seasons 8-12, he suffered flanderization and reverse character development.

Bad Qualities (Seasons 8-12 only)

 * 1) He went from being a developed and courageous ninja to trying to an annoying character who tries to be comical for no reason.
 * 2) In Season 11, he constantly berates his Master, Wu, for Aspheera taking his powers away, because he's the one who she wants, when he's had his powers taken away before because of Wu's history with a villain BEFORE, and they were well within volition of stopping Aspheera from coming out of the tomb after Zane warned them, as seen here
 * 3) He's incredibly cocky. While yes, he was in Seasons 1-7, he developed over time and it became less prevalent. Now, it seems as if it's his main trait.
 * 4) In Season 12, he's really annoying as he constantly uses sarcasm to an annoying degree and is whiny.
 * 5) As said in BQ #1, he's always trying to be a comic relief character like Jay in these seasons, which is imposing because Jay's actually funny.
 * 6) Addressing the elephant in the room(for Ninjago fans), in the Season 8 finale, he hesitated possibly giving up his powers to save Lloyd just because "They would need their powers to stop Garmadon", which completely goes against his character in the previous seasons, where he has a strong relationship with Lloyd and would give up anything to protect him.

Good Qualities

 * 1) He managed to almost recover from his flanderization in Season 13, unlike Dareth.
 * 2) The scene in Season 10 where Kai comforts Nya regarding Cole's "death", was a very heartwarming scene.
 * 3) The scene in season 9 where he teaches young Wu a lesson about confidence could be considered good to some people.
 * 4) His voice acting still suits him and is pretty good.
 * 5) He's miles better than his movie incarnation.
