Growing up in a Nation of Fire

Over 300 years after the assassination of Avatar Korra, her successor Avatar Genji would fall in battle to an arch villain that was as old as the ancient avatar of earth himself. With him gone the world eagerly awaits the return of the new avatar in the firenation. However in a world where the non-benders gained superpowers and quirks how does the Avatar fit in with the rest of this? Has the world seemingly matured to the point where the avatar isn't needed or are they now destined to be the most powerful and purest of heroes?

This is a crossover between Avatar the Last Airbender series and My Hero Academia, I do not own anything as this is a fan based parody.
