Shippuu! Iron Leaguer

Shippuu! Iron Leaguer (“Whirlwind! Iron Leaguer”) is a side-scrolling action game based on the anime of the same name featuring a squad of sports-themed mechas. The game features Magnum Ace and Kiai Ryuken who represent Baseball and Karate, respectively.

The game was exclusive to the Japanese Game Boy and no further games were based on the license. The characters would eventually appear in Super Robot Wars Neo for the Nintendo Wii, however.
