WARNING: HUGE DIEBUSTER SPOILERS ON THIS PAGE. Edit
Buster Machine 7 is a gigantic version of Nono dressed in white and red with missile launchers coming out of the sides of her legs. While in this form, Nono's hair changes from pink to orange. She fires the Buster Beam by arching her back, curling herself into a backward "C" shape and forming a ball of energy behind her, then releasing it.
