Wonder Momo is a Japanese arcade game by Namco released February 1987. On 15 May 2012 a webcomic series began, and this generated enough interest to result in a 5-episode OVA series of 7-minute shorts being produced based on the daughter of the original Momo, named Momoka, who also takes on the mantle of Wonder Momo.
The character has also been in the Queen's Blade series, specifically the Queen's Gate: Spiral Chaos.
A personal computer version of the game was released April 21 1989.
She is shown wearing a towel in the ending.
