Encounter!? Minerva X's Appearance!

'''Encounter!? Minerva X's Appearance!!''' is the sixth chapter in the Robot Girls Z web manga. It marks the web manga's debut of Minerva X.

Summary
Robot Girls Team Z and Team G go to Photon Power Town's hot spring resort. While Get-chan does not like the idea of bathing in the same area as commoners, Jeeg-san likes the idea. Lurking in the shadows are Baron Ashura and her Mechanical Beast Girls. At the bath area, both teams are astounded as they get in. Z-chan gets a little jealous of Grenda-san and Jeeg-san's mature figures but then teases Gre-chan about her child-like figure. Soon Minerva X walks into the hot spring and embraces Z-chan much to her and the rest of Team Z's surprise. As Team Z attempt to explain who Minerva is to Team G, Minerva cuts them off with her fake backstory. At another spring, Ashura is highly confident that her plan with Minerva is going perfectly but Garada K7 informs her that Doublas M2 passed out from the heat of the bath.

Minerva begins to wash Z-chan which makes Gre-chan angry. Minerva is then contacted by Ashura to continue with the plan and Minerva begins to fondle Z-chan. Snapping, Gre-chan gets into a fight with Minerva while accidentally removing Minerva's towel which reveals that Minerva is a boy and his private area in front of Z-chan. Enraged at what happened, Gre-chan unleashes a Thunder Break that caught Minerva as well as Ashura's group in the blast.
