=x Lucky I used my anti-damage earlier..
Quite hard, almost everytime lack of battlechips when I hit this boss until 1000+ hp left.
Oh look, last epic battlechip LOL
For your information, you MUST complete all your Standard chips, Mega chips, Giga chips, Dark chips and Program Advance (P.A), and also defeat Bass Omega in Nebula Area 6 THEN you only can battle with Nebula Grey Omega.
