How about a spirit version of 9 tails from naruto. It can be a spirit of yin and yang energy or chi itself. It will give the mc a large stat in chi and maybe use the naruto world logic to change the nature of chi to create other elements (maybe make it so that the mc will use more chi when bending other elements).
One of the best "Legend of Korra" fanfictions out their especially in webnovel. I really hope the author complete the novel. The MC has a decent ability while still not being over powered.
Mineta is a total pervert it's best to remove him rather than a person from 1B
It's canon, emphatic replication is a ability that allows the user to replicate the abilities of people who the user is in a certain proximity to. Later the user is able to use the ability of others just by thinking of the person who he once replicated. The web series name is called "Heroes". The show also holds other abilities like "intuitive aptitude" which allows the user to replicate the ability of others but he have to see their brain so he have to kill them and their is a ability called "power absorption" which which allows the user to absorb the ability of others. And their are other abilities like time and space manipulation, healing, regeneration, and many other bizzare abilities.
Won't you have to remove a person from 1B then.
You are right about that but it's not webnovels problem(i think) because almost all platforms have issues with it's search option now. There is a chance that it has something to do with the recent changes in google and android after the china incident. Now when we search for info or other thing we have to be specific to find it unlike in the old days when we search for something it will find anything that is remotly related to it.
Can you also make the mc have other sub bendings like combustion bending, lava bending (technically earth bending sub type but you know it have fire in it), spirit bending (again water bending but instead of water you use the negative and positive chi to change the nature. Maybe make it a chi control technique),and other things like Scorch style from naruto, different fire from doupo, and trying to make lightning a main bending not just sub skill by mc being able to generate lightning himself (without changing chi nature) and making black lightning etc..
Like kevin, not kevin himself maybe grandson of max's plumber friends or something.
Make the mc a asmosian (kevin) but with the ability to transform into aliens and thier ultimate form. It would be better if he can store and retreive the dna of aliens he already absorbed (in short make him have ability of omnitrix to transform into aliens but without the high tech things like dna alteration, scanning and other stuff)
