Right, so I used a code to unlock all the characters and noticed some appear to lack the ability to do supers. Uber Hinata, ANBU Kakashi, Kabuto, and Tsunade's assistant all do some charge move instead that appears to power them up, but there doesn't appear to be a difference in damage inflicted. Also, on the character selection screen you can press R1 to cycle through three different kanji underneath your character portrait; what is that for?
