Tagged Crossover for the heavy Dragon Ball Z reference (and a smaller one of Naruto). No characters from either anime/manga appear in Equestria, as I strongly believe that ponies should resolve their problems on their own. ;)
Rated Teen just to be on the safe side (it's a Dragon Ball style fight, after all :P ).
