Dream Mix TV World Fighters is a fighting game similar to the Smash Bros. series. A collaboration between Konami, Hudson and Takara the game features characters such as Snake, Simon Belmont, Master Higgins and even Optimus Prime. While personally I think the game holds no candle to Smash Bros. it's pretty fun in it's own right.
This video shows a match between Snake, Simon Belmont, Twinbee and Momotarou.
