While most versions of Art of Fighting end on a cliffhanger just before Yuri reveals the true identity of Mr. Karate to Ryo and Robert, the Super Nintendo version extends the ending to reveal that Mr. Karate is Ryo and Yuri's father Takuma, who was blackmailed by Geese Howard and Mr. Big into killing Jeff Bogard (Father of Terry from Fatal Fury)

If a player finishes off King with a special or super move in round two, it will shred his shirt, revealing that he is female. This was removed from the SNES version.
