>>54104380Avatar matches a lot of criteria but it misses the major one: all the powers in Avatar are personalized. There's very little of the kind of partnership we find in Pokemon, benders use their own power and rarely if ever have intelligent monstrous partners.
That and the avatar world is simply a lot more cruel and depressing. Bending helps their lives and does make it magically wonderous, but nowhere near to the extent that having a pet psychic cat thing would.
