Encounter!? Minerva X's Appearance! (Manga)

Minerva X is a Mechanical Beast Girl developed from the data of Robot Girls Team Z and was created for the purpose of disrupting their teamwork. Despite his feminine appearance and voice, Minerva X is actually an Otokonoko.


Minerva is a feminine-looking teenager with long brown hair and red eyes. He wears an outfit similar to Z-chan's featuring the same jacket and skirt even a ribbon in his hair but with a black top covering the chest with a pair of red plates to make it resemble the breast-like heat sinks of the original Minerva, indigo gloves, and boots. He wears a hat in the shape of his namesake's crown but with a red horned face with yellow eyes that changes expressions with Minerva instead of a bird.


Minerva has a crush on Z-chan and strives to get her attention. When it comes to others however such as the other members of team Z, he badmouths them and considers them unworthy of Z-chan's attention, especially Gre-chan.


Minerva's abilities are likely the same as his original counterpart's but has only demonstrated the Rocket Punch.


Anime Edit

Minerva first appeared in the park to greet Z-chan while badmouthing the other Robot Girls. While he manages to get Z-chan alone by making Gre-chan look like the bad guy, Minerva starts to make a move towards her revealing himself to be a boy. Z-chan was astonished by this before Gre-chan broke down the door and the entire break room. She and Minerva then started to fight which ended when Z-chan took a blow for Gre-chan and Minerva left after seeing the bond between them. However Minerva returned the next day to get Z-chan's attention but got into another fight with Gre-chan. He would later appear to help Z-chan fight Great General of Darkness-ko, only to disappear for the next scenes.

Manga Edit

Minerva appeared at the Photon Power Town hot springs where he embraces Z-chan while in the bath. He cuts off all attempts to reveal his true identity with his fake back story. Minerva washes Z-chan's back until fondling her which makes Gre-chan snap and got into a fight with Minerva which resulted in Minerva losing his towel revealing his private area in front of Z-chan. Angry, Gre-chan unleashes a Thunder Break that knocked out Minerva.
