Yeah, I refer to that whole part as "The Imperial Air Force" because it's lot of battles linked together with no where to save in between. This part was crazy hard. (Reminds me of my NSGIENC FFX challenge experience now ><) I want to give you one hint to save you some frustration I unfortunatley dealt with for hours before discovering it. The Siren esper is PURE GOLD in those pre-Ultros and Chupon fights, it will silence the whole screen so they can't use that Absolute 0 crap on you. Make sure to equip Siren on someone with REALLY high speed so that they can get that off at the beginning of the battle before they get a chance to use it on you. I chose Locke with all speed benefitting equipment, GOOD LUCK!
