What if the new team avatar and the grandchild of toph bei fong who's name after her was teleport to the old days where Avatar Aang and the Gaang helped people after the war? Then they get teleported back to their place and the Gaang got teleported to korra's team avatar World? (I do not own avatar the last airbender and legend of korra but I owned my oc in the story. I do not own the cover of the story)
