The King of Fighters XII (KOF XII) is the latest installment of the fighting games series developed by SNK Playmore. The game was released in Japan in April 2009 for arcades with an home versions for Xbox 360 and PlayStation 3 in July 28 of the same year. Due to the time the developers took to make the sprites, there are only 20 playable characters (the lowest number of characters ever had in a game from the series) but many more unused ones were created in concepts during the development.

Also, Mr. Lip Buster from the Ignition Entertainment Forum has found the names of more unused / removed characters in the game’s code: Vice, Hwa, Takuma, a boss, Dark/Orochi(?) Ash, Mai, King, Yuri, Classic Iori, and Billy were all planned and not included. There are 7 more empty spots with no character at all. That’s a total of 17 characters gone from the final version, 10 that had made it to planning and 7 that never even made it to the data. tKoF XII was originally planned to be the conclusion of the Ash saga.
