Olga is a female Microid in the anime Microid S, introduced in the eighth episode. In this series, Microids are humans captured by Gidoron, a highly advanced insect civilization, and shrunk to miniature size to be used as slaves. Olga appears as one of these Microids who has escaped from Gidoron's world, and after her escape she is rescued by Yanma, one of the three main Microid heroes. Her arrival creates friction within the group because Ageha, the other female member of the team, regards Olga with suspicion and distrust. Olga's motivation at this point in the story is to stay free of Gidoron after fleeing from the insect empire, and her role is that of a fugitive seeking refuge with the escaped Microids. As a Microid she shares the condition of the other escaped characters, being a tiny insect-sized human being who has broken away from the empire that transformed her.
