When she begins the phase of the battle where she transforms into Samus, a fully charged plasma beam shot will stun her in both of the Samus forms. (Varia Suit and Morph Ball)

Screw Attack works very well against Gandrayga! (MASSIVE DAMAGE!!!)
On Normal difficulty, in her normal form, it took off about 1/5 of her lifebar. She then morphed into the swarm of little things, a single SA took her almost to half health. Then when she changed to Ghor, two Screw Attacks to the head sent her into the next phase, and a few more well-timed SAs finished her off.
