The original Wonder Momo was a side-scrolling arcade beat-'em-up that cast players in a superheroic role during a series of live stage shows. As the young protagonist Momo, players battle waves of minor enemies in each level before dramatically transforming into Momo's alter-ego Wonder Momo, who wields a powerful energy hoop for the remainder of the stage. Though the game saw a home port to the PC Engine (TurboGrafx-16) console, no version of Wonder Momo was ever released stateside.
WayForward's reboot of the series follows a storyline introduced in Shiftylook's Wonder Momo webcomic, which premiered in 2012 alongside other commissioned comic strips based on classic Namco franchises. A Wonder Momo anime series is also set to premiere this year.
