I'll allow powerful abilities, but something as powerful as the rasengan, which was so advanced only three people ever could master. (the third being kakashi, screw you naruto, you can't learn something like that in five days!!!) But you may use rough attacks, more brute force(chakra) then actual control, so to say, then advanced techniques.  and sure Digitl, feel free to add that they know each other aswell, sense their both anbu.
