Spider-Man. One of earth's greatest heroes, he's saved countless people over the years and he's still doing if today. So if the big apple can have Spidy, why not add one to Republic City? A OC story, that takes place before Korra hitchhiked to the big city. Watch out, here comes the new Spider-Man.
A non-too serious crossover idea inspired by the fact that JK Simmons has played both J Jonah Jameson and Tenzin. In this fusion fic, Korra's attempts to learn airbending from the cantankerous son of Aang hit a roadblock when she learns that Tenzin has one thing on his mind and one thing only: getting some pictures of that no-good Spider-Man!
