Mako x Male Reader

y/n is from the water tribe. He had to hid from other people. Only some people know who he is and why he doesn't show his face. Y/n is one of a kind he can bend ALL the elements. When I say ALL the elements I mean he can bend every thing you can think of. He can make new bending or just learn how to bend by watching someone bend just once. He also travels a lot so he can learn other bending. But no one knows he can make new bending or can bend all the elements to. So when he sees people he only tells them some of the things he can bend.
