Synopsis
A group of aliens with plans to conquer Earth launches an invasion of Tokyo. Momoko, who dreams of becoming an idol, becomes involved in the battle in a surprising way. Warudemon, the ruler of the alien empire, employs numerous strategies to target Momoko and those close to her. In response, Momoko resolves to fight back against this threat. Wonder Momo first appeared as an arcade game in 1987. It was a relatively simple side-scrolling beat 'em up game by modern standards, featuring a heroine who could transform and wield a hoop.
