I do not won Avatar the legend of Korra the animated series
or own One Punch-Man the manga/anime series except OC monster this is purely fanart.
Ever since I saw a crossover fanart of OPM and Avatar the last Airbender together I just knew that I have make this.
I was thinking like a AU Crossover where Saitama and every other heroes and monsters from OPM live in the Avatar Universe, in Republic City where most of the heroes are Benders
say Genos is a Fire Bender, Silver Fang a Water Bender, Speed of Sound Sonic an Air Bender(who isn't a hero) and Tatsumaki the Earth Bender.
As for the Non-Benders who uses weapons, physical strength and gymnastics, gadgets like
Atomic Samurai master swordsman, Child Emperor kid genius and TankTop Master the muscle.
Finaly Saitama, the Non-Bender who can kill monsters with one punch, who no one knows he exists and will be Korra's Strongest Master.
