Gameplay
Wonder Momo is a loose parody of a typical Ultraman-style superhero series, utilizing a then-rare female protagonist. When the game is first started, players are treated to a parody of the MGM logo featuring Momo instead of a lion. The game then cuts to a scene of a theater stage, where a play begins starring Momo, a young girl who gets super-powers. At this point the game puts the player in command of Momo. Rather than playing a hero who must save the world, the setting is that of a live stage show (set at the "Namco Theater"), and players actually control an actress who is merely playing the role of Momo/Wonder Momo. This game also features voice samples (in Japanese).
As Momo, she can only attack using kicks, and in doing so builds up her "Wonder" meter. When she touches a cyclone icon or spins by herself, she can become Wonder Momo and also can attack using the Wonder Hoop, which can be reused as long as she is Wonder Momo. After the Wonder Hoop is thrown, she won't be able to throw anymore, while she'll have to wait for it to bounce back to her. She sometimes can shoot small waves of energy in whatever direction she faces, which is based on the similar move by the Ultraman characters. Her most powerful move is the Wonder Typhoon, a more powerful version of her small energy wave move which shoots numerous amounts of them toward the left and right simultaneously while she spins.
The game is noted for featuring some slightly risqué content for the time, in the form of fanservice at Momo's expense. When Momo jumps, players can visibly see her panties. Also Momo needs to be wary of a photographer in the audience who is determined to get a peek under her mini-skirt. If he is successful, Momo will be "embarrassed" (stunned) for a short time. Additionally, one of the images that appears on the curtain (at the beginning and end of some stages) is Momo wearing only a towel.
