Strategy
MP Drain strategy is highly recommended as it has the benefit of denying the use of Zero Shift, which has a high potential to end the fight. The basics of the super bosses apply, but there are a few things one should keep in mind: Check here and here for detailed information on all the super bosses and everything you can make use of to defeat them.
 * Holy Martyr and other such skills will not activate during Time Stop.
 * Skills that can activate at the end of turn from characters such as Naia (100%), Mimi (33%), Pochi (33%) and Panty Sensei (25%) immediately interrupt Time Stop.
 * Ongoing skills that have an effect at the end of the turn (Request Reinforcements) can also use up some of the turns of Time Stop. 1 if one person, 2 if more.
 * Zero Universe doing 9 hits means it can very likely end up killing someone even with multiple layers of Vicarious Clara so keep up enough to make that unlikely.
