When Gandrayda's health is halved, she will pump her fist and charge electricity along it, run, do a cartwheel and then become Samus-G, running a bit more before aiming her Arm Cannon at the real Samus. During this form's battle, she uses the Boost Ball to charge around the arena, usually back and forth, in a very similar manner to the battles with the Boost Guardian and Dark Samus in Metroid Prime 2: Echoes. She is said to wield the Power Beam, but it is actually a purple laser beam.
