Feh! For Frequency, Freely, Fantastic Final Fantasy Foes ****ing Fatalize Favengers.
Yeah. Favengers.
Anywho - All materia and prep and 'status sustaining' certainly help the FF crew.
Everyone hasted, shielded, barrier'd, shelled, reflective, walled, et cetera.
All summons mean that The Final Fantasy crew can use the ten minutes prep to also call up Choco/Mog, Shiva, Irift, Ramuh, Titan, Odin, Bahamut, Kujata, Alexander, Neo Bahamut, Leviathan, Hades, Phoenix, Bahamut Zero, Typhoon, and the Knights of the Round.
A mega all means that anytime anyone on the FF side attacks ANYONE with ANYthing - ALL the avengers get hit simultaneously. Pre-emptive means that the FF crew get to go first. Luck Plus means that the Scarlet Witches' probability manipulation won't work as well. Speed Plus means that everyone on the FF crew will be moving about faster than normal (which is already bullet-time-fast).
Qudra Magic means that the Avengers get Ultima-bombed four times. Final Attack plus the phoenix means that even if the avengers someone win, the entire FF7 crew is revived at full health.
All the while, ultimas are going off, tons of comets (not Meteor - but Comet) are falling, Death magic is going everywhere, half the avengers are turned into miniature versions of themselves, or toads, the Avengers are slowed, or even frozen in time, Tornados and earthquakes are ravaging them, any magic use gets 'silenced.'
And, hell, if they need to, the FF crew can just 'Heal' or 'revive' as often as they want - infinite MP.
Not to mention the fact that the FF crew can just use Deathblows (that'll hit EVERYONE on the avengers squad) can morph any of the avengers, can use W-Summons, can take control of the avengers via manipulate, or use 4x cut to attack four times as fast (as they do hasted, no less.)
You...really...really...REALLY made this a stomp in the Final Fantasy team's favor.
