METROID PRIME 3: CORRUPTION
A shapeshifting bounty hunter, Gandrayda, along with Samus, Rundus, and Ghor, are sent to planet Norion to stop the Phazon corruption. During this mission, however, the 4 of them are blasted by Dark Samus and are soon infected with the Phazon. Samus does not see Gandrayda again until she visits the Pirate Homeworld. With the corruption now taken hold of her, Gandrayda attacks Samus; taking on several different forms throughout. Upon her defeat, she is absorbed into Dark Samus.
