Invincible! Team Z's New Power

'''Invincible! Team Z's New Power''' is the finale of Robot Girls Z+, introducing Team Z's upgraded forms also known as Team Z EX.

Summary
After destroying her own building Gilgilganko believes she has won. But amidst the rubble and dust, Team G (except Jeeg-san) was protected by Get-chan's staff. Z-chan was peeved that she and the others were not helped but Ganko continues her attack. The Robot Girls fight back but are easily overpowered. Z-chan is frustrated about not being able to fight back. However, Team Z is helped by Prof. Yumi by giving them new equipment to power up. Team Z upgrades to stronger forms while calling this new state Team Z EX. Team Z EX is able to turn the tables but their combined attack Koshiryoku Beam Dynamic misses due to it being slow. When Gilgilganko attempts to finish them off, Boss accidentally reflects the energy ball with her mirror sending it at Ganko destroying her costume and sending her flying. Team Z in this way is victorious.

At the temporary Nerima City Hall, a statue is made for the heroes of Nerima. But the statue is of Boss and her lackeys, for being the one that played the most crucial role in defeating the monster girls (albeit accidentally) while everyone else was knocked out or out of power much to Z-chan's frustration.
