How To Beat Him: Charge up your Hyperbeam and dodge Dark Samus' attacks. When she brings on the attack of the clones, kill off those kitties and go after the momma cat again. When Dark Samus is in Aurora Unit 313, dodge all her attacks and take out the tentacles. Just push 313's wig back, blast at her brain, and she's going down soon.
