Manipulate into the GT Safe Spot and farm for energy. Keep your Missiles below 30 to force the attack pattern that has drops. Taking damage to get ready for the interrupt may require leaving the safe spot. Leave enough to survive one hit from GT. Push GT back into the corner, run into and through to get your shinecharge. Come back and interrupt using whatever attack pattern is happening. After you gain blue suit, you'll need to use any standard kill strategy. Blue suit will not help with defeating GT except for invulnerability.
