Gundam Build Fighters (2013)

S1E25 Promise

After Sei and Reiji win the tournament, Chairman Mashita panics. His Arista reacts, resonating all the Plavsky particles inside the PPSE Stadium and forming a 1/144 scale replica of the Zeon space fortress A Baoa Qu above the facility. The Gunpla Fighters must unite, infiltrate the fortress, and destroy the Arista before it triggers a catastrophe.
