Debuting in 1985, Yie Ar Kung-Fu is a 8-bit fighting game where the main character, named Oolong, fights against various martial arts masters to win the title of "Grand Master" and honor the memory of his father. In the arcade version, the player fights against 11 other martial artists (5 to 13 in the home versions). Yie Ar Kung-Fu is the first fighting game to feature a variety of unique martial arts-based characters, fighting styles, and stages.
While originally inspired from early Kung-Fu and martial arts films, this basic "trait" of characters fighting against one another in different locations is something that would later be used in nearly all future competitive fighting games. Furthermore, Yie Ar Kung-Fu was the first video game to feature two character life bars at the top of the screen which drained into the letters "K.O"... another iconic trademark that nearly all future fighting games would adapt.
