In terms of non-Naruto related powers then I guess the ability to control elements would be cool. Of course I'd be evil because where is the fun in being a goodie-two shoes.
If I can imagine myself doing it, I can do it. Personal reality warping, benefits of reality warping without interfering directly with others in unintended ways. I'd be a Red Hood type at first, only killing criminals and corrupt, being a chaotic neutral person, but with the way I am, I'd probably end up killing as a release, and become a huge sociopath.
The ability to clone myself as much as I want. I could simultaneously make money, get an education, **** women, have a social life, dig for jewels in Africa, run a marathon for charity , anything all while the original me is at home, being lazy.
