Karate Champ, known in Japan as Karate Dō (空手道, "The Way of the Empty Hand"?) is a 1984 arcade game developed by Technōs Japan for Data East.

Karnov (カルノフ, Karunofu?) is a 1987 platform arcade game. It is the debut of Data East's mascot of the same name. After Data East became defunct due to bankruptcy in 2003, Paon, a company comprising former Data East staff, acquired the rights to Karnov, along with multiple other Data East games. In the game, players take control of the title character Jinborov Karnovski (ジンボロフ・カルノフスキー?), or "Karnov" for short. Karnov is a strongman popularly illustrated as being from an unspecified part of the Soviet Union's Central Asian republic as shown on the original arcade flyer and again in Karnov's Revenge. As Data East's mascot, the title character was reintroduced in many other Data East games, including Bad Dudes Vs. DragonNinja in which he played a boss in the first level. Karnov later appeared in the 1994 Neo-Geo game Karnov's Revenge. This game, also known as Fighter's History Dynamite, is not a sequel to the original Karnov, but to Fighter's History, a competitive one-on-one fighter in which Karnov was the final boss.

Kart Fighter (Chinese: 瑪莉快打; pinyin: Mǎ lì kuài dǎ, lit. "Mario Fighter") is an unlicensed 2D fighting game produced for the Nintendo Famicom. The game features unauthorized appearances by Nintendo's mascot Mario and the rest of the cast of Super Mario Kart in a port of Street Fighter II. Since its release, Kart Fighter has received some media attention, including mostly positive reviews, in part because of its perceived similarity to the later Super Smash Bros. series.
