Wonder Momo

Wonder Momo is a loose parody of a typical Ultraman-style superhero series, and 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 and a "Modoki" instead of a mask. The game then cuts to a scene of a theater stage, where a play begins starring Momo, a young woman who gets super-powers. At this point the game puts the player in command of Momo. Rather than playing a hero who needs to save the world, the setting is that of a live stage show (set at the "Namco Theater"), and the player is actually controlling an actress who is merely playing the role of Momo/Wonder Momo. The 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 tornado icon, or spins around by herself, she can turn into Wonder Momo and can also attack using the Wonder Hoop, which can be reused as long as she is Wonder Momo. After the Wonder Hoop is thrown, she will not be able to throw anymore, while she will have to wait for it to bounce back to her. She can also shoot small waves of energy in whichever direction she faces (while she is crouching), which is based on the similar move by the Ultraman characters. Her most powerful attack is the Wonder Typhoon - a more powerful version of her small energy wave attack which shoots numerous small energy waves towards the left and right sides of the screen simultaneously, while she is spinning.

The game is notable for featuring some slightly risqué content for the time, in the form of fanservice (at Momo's expense). When Momo jumps, the player can visibly see her underwear. Momo also needs to be wary of photographers in the theatre audience, who are determined to get a peek under her miniskirt. If one is successful, Momo will be "embarrassed" (stunned) for a short period of time. Additionally, one of the images that appears on the theater curtain (at the beginning and end of some acts) is Momo wearing only a towel.

The titular character made numerous appearances outside of her video game, mostly in Namco's other video games. Wonder Momo appeared as one of the playable characters in the Japan-only, tactical RPG title Namco x Capcom, partnering with Bravoman, while Amazona appeared as an enemy character. Momo often covered herself, alluding to the original game. Some artifacts, models and costumes based on Wonder Momo appeared in some other Namco titles. She appeared as a magnus card in the Namco RPG Baten Kaitos: Eternal Wings and the Lost Ocean, made a cameo appearance as one of Anise's dolls in Tales of the Abyss, had her normal self appear as one of the various floats that appear in the bonus stages of Marvel Land, and had her "Wonder" costume appear in Tales of the World: Radiant Mythology 2 and in Catalogue 4 in the Xbox 360 game The Idolmaster. Her latest appearance lies in the PSP strategy RPG Queen's Gate: Spiral Chaos. A theme based on Wonder Momo, with the game's characters is featured in Pac-Man 99, as special DLC.

Wonder Momo received a brief adaptation as part of the manga anthology Famitsu Comix: The Shape of Happiness (しあわせのかたち, Shiawase no katachi), published in the Famitsu Comics collection from March 1989, drawn by Tamakichi Sakura.

Besides appearing in video games, J-pop singer Haruko Momoi released an album influenced by the video game fully titled as WONDER MOMO-i〜New recording〜 (a pun combining her last name with the name of this game). It utilizes both the game's main gameplay theme and the "henshin" (transformation) theme. Yujin released a gashapon figure of Momo as part of the "Namco Girls" collection.

In Japan, Game Machine listed Wonder Momo on their April 1, 1987 issue as being the fourth most-successful table arcade unit of the month.[10]

Reviewing the PC-Engine home conversion, German publication Aktueller Software Markt (ASM) liked the game's large sprites, soundtrack and special effects, alongside its simple and easy-to-understand gameplay. The Games Machine magazine found it to be "great fun" for its bizarre premise, gameplay and visuals,[9] while Famitsu praised its large, detailed sprites and catchy soundtrack.[8] Famitsu also praised the PC-Engine version for being a faithful conversion of the arcade release.[8]
