Godlike:
Sephiroth (FF7) vs Zio (PS4): Faster, and Wall helps, yeah.
Yunalesca (FFX) vs Cecilia (WA1): Cecilia has a slim case here, but it requires parasol blocking healing magic... we know it doesn't block Cecilia's own, and as far as I know no enemies cast healing on you, but the default view I have is to say parasol does not stop it, then. So zombie gets inflicted just fine and then death ensues. Even if she blocks the healing she's likely toast due to Mind Blast's status in the final form (not parasolable).
Magus (CT) vs Chaos (FF1): Has non-elemental magic.
Celes (FF6) vs Psaro (DQ4): Sure. To make matters worse I am increasingly leaning against allowing overlevelled spells, so while I might squint for Ice 3 that would certainly mean no Meteor.
Heavy:
Decus (SO2) vs Lin (BoF5: No comment.
Rofel (FFT) vs Sonya (S1): Breaks her armour then crushes horribly.
Middle:
Beowulf (FFT) vs Rena (SO2): Now to go through the motions to set up Beowulf vs. Fiora mk 2.
Gallows (S3) vs Twakin (WA3): Infinite healing and the match goes long enough for him to build up and stay at 100 FP and slowly grind Twaikin down.
Locke (FF6) vs Fiora (FE7): ohnoes, Locke ranged weapons in the DL. Never mind I don't think I'd see boomerangs hitting weakness on pegasus knights anyway, they're much more like Hand Axes.
Light:
Luna (Lunar:SSSC) vs Mustadio (FFT): um yeah
Wan Fu (S3) vs Earnest (SF1): Looks like Wan Fu 4HKOs while Earnest 5HKOs due to differences in durability. Earnest is faster but it's not enough. Both are terrible, wow, enjoy getting stomped by Luna.
