This makes me think of the Street Fighter II anime movie. In the anime(s) they seem to waffle on exactly how special the special moves are. For example, there are a few fireballs thrown and they make a sorta big deal about it, but then near the end of the movie with little or no fanfare Guile tosses a sonic boom and it knocks down a house.
