The issue I'm having is nothing drops energy unless I'm below 99 with 0 tanks left. I sat and fought him for a good 20 minutes with only the orb on his back left, successfully dodging all his attacks, but I could never get over ~110 energy because his hands would ONLY drop energy once I was in the danger zone, and usually just a purple +10 at that. This goes for both the hands he shoots at you, and the hands that grab orbs from the side of the arena. If I have a full tank, even if I'm at 0 energy, no power ups will drop. This happened in two separate attempts before I called it quits for a little while. I'm not making any huge mistakes or anything, it just seems like I'll never have enough energy to finish the fight with the required hypermode uses unless energy powerups drop, which seems like it should be happening but it isn't.
On a sidenote I thought both the other prime games were FAR too easy, I don't think I died a single time while playing either of them through the first time, so I don't know why this is giving me so much trouble.
