Game: Virtua Tennis
King was actually an unlockable "boss" and was known in game as the "perfect player." The thing about King was that he was actually kind of smart; just like an old chess program it was fun to match wits with a videogame opponent who was difficult but didn't resort to cheating. After you top King solo you had to play him with his equally humble doubles partner "Master." The doubles match is much simpler as King was no doubt dejected after a humbling loss worthy of a jackoff who calls himself "King."
