Alisa's S-Craft: .375 PCHP. With the last two boosted at +50% damage, that's 1.5 PCHP of nearly unstoppable damage. If she survives a single turn before being defeated, 3x Purgatorial Flames = an additional 1.2 PCHP damage, or 2.7 PCHP total. That's ignoring the ADF debuff as likely irrelevant, too, so maybe a bit more at times. Ouch.
Alisa Reinford vs. Sephiroth
Well, Seph does require a turn to Fly before using Pale Horse, but yeah, I don't think Alisa 2HKOs. ANd dead FF7 PCs really stay Frog'd after being revived? Weird.
Alisa Reinford vs. Lavos
Alisa has to dump her MP & SP into blowing up the Central Bit which means she runs out of gas to kill the Core. I guess she can win if Purgatorial Flame + Radiance Arc kills the Central Bit & Filler Bit, Alisa is lagged to hell, and then she has to use MP-efficient Cross Crusades to damage the Central Core. It isn't going down, though, and then SP-less Alisa has to deal with revived Bits. SHe'll get all her EP back after she dies, sure, and if she can resolve another spell + S-Craft, she can go in for round 2 on the Central Bit and maybe finish it off. That said, I don't think I buy PF + S-Craft as enough to turn 1 kill the Central Bit, and that's really bad, since while she'll kill the Central Bit on life 2, she still won't kill the Core, and then the Central Bit will have its revenge and take lives 2 & 3 with Crying Heavens. I guess Alisa can hype the ATS debuff from Altair Cannon as stopping a OHKO of her from Crying Heavens? But I dunno.
Alisa Reinford vs. Xorn
Sure, I see Alisa resolving at least SOME spells, and while I'm inclined to see Xorn as a bit tankier-but-not-as-fast as the stat topic does, I don't think he's tanky enough. Just resolving that first Purgatorial Flame is pretty close to a win anyway with 1.9 PCHP.
Alisa Reinford vs. Chris Lightfellow
Chris's MDef knocks off about 0.08 PCHP of damage from magic, so Alisa's max S-Craft burst is around 1.26 PCHP. Chris has around 1.06 PCHP, so yeah, she's gonna need to sneak in a heal somewhere. Still, don't see why she can't manage this? Silent Lake, Alisa S-Crafts, Chris 3HKOs Alisa under SL, Alisa revives, Chris sets up SL again, kills her again just as SL is about to expire (and eats a boosted S-Craft), then uses a very fast-casting Kindness Rain. Alisa can now resolve one spell against a full-health Chris (who can also resist Fire). I don't think she has any that are decisive, and she loses once Chris casts SL #3.
I guess you could see Yellow Scarf as not blocking Blind and/or Burn, which Alisa can inflict with Crafts, but seems an uphill battle otherwise.
Alisa Reinford vs. Lambda Zellweger
Alisa Reinford vs. Wugui
Alisa Reinford vs. Jowy Atreides
Salamandra: Guesstimating somewhere around ~.90 PCHP damage off Salamandra's damage for my views, and looks like a bit less than 3 PCHP.
Salamandra vs. Sephiroth
Salamandra like 3HKOs at best through Wall, probably 4HKOs. OTOH, Sephy's damage is no great shakes to me either. They both lose their first turn, then Sephy 4HKOs himself, I guess? Maybe? Very narrowly if so. Close.
Salamandra vs. Lavos
How long does Flaming Zone last? FZ, VC Trap, SB the Central, then spam SBs at the Core and hope it's enough before they revive. I think Salamandra 4HKOs here, but that's 6 turns after FZ. That said, Salamandra miiiight win anyway depending on CT ATB plot, since he can hypothetically only eat 2 Crying Heavens and kill the Central Core again. Abstain I guess.
Salamandra vs. Yu Narukami
Usually prefer not to vote Yu, but this one is easy.
Salamandra vs. Xorn
Speed split kinda bad here. Salamandra narrowly misses the 2HKO too, so FZ->3HKO = 4 turns of Xorn, which is more like ~6-7 turns.
Salamandra vs. Chris Lightfellow
Too tanky.
Salamandra vs. Lambda Zellweger
Too tanky.
Salamandra vs. Wugui
Salamandra vs. Jowy Atreides
Too tanky. Maybe Riou could do it, though?!
Procyon vs. Sephiroth
Procyon vs. Lavos
Use a double to blow up the Center whenever it's alive, chip otherwise.
Procyon vs. Yu Narukami
Procyon vs. Xorn
Turnsplit too bad here.

Drain strats. Lavos MIGHT win off a lucky Spell but I doubt he has time for it.

I'll trust everyone that XS1 KOS likely gets wrecked, except for maybe Chris or a really low-respect Jowy. XS3 KOS... has the -90% damage move in Phantom Stinger which nobody uses in-game, and Blood Dancer. Arguably she should face a 3-turn damage average though if she uses BD, since I'd imagine it'd be notably higher than the 1-turn.
KOS-MOS vs. Sephiroth
KOS-MOS vs. Lavos
Blood Dancer, eat a Crying Heavens, then blow the Central Bit up, then blow up everything else.
KOS-MOS vs. Yu Narukami
KOS-MOS vs. Xorn
Time for BUFF PREVENTION MOVE HYPE
KOS-MOS vs. Chris Lightfellow
Uhhh depends on if Misty seals super-moves. Probably.
KOS-MOS vs. Lambda Zellweger
Depending on XS3 speed antihype, KOS might never see turn 1, but if she does, she can throw up her damage reduction buff... Lambda might actually kill through it though since KOS will already be wounded.
KOS-MOS vs. Wugui
KOS-MOS vs. Jowy Atreides
XS3 KOS is actually pretty tanky, she eats Hungy Friend then sustains through anything else Jowy has.
Alisa: 4-3-1
Salamandra: 4-3-1
Procyon: 3-5
Terra: 2-6
KOS (XS3): 2-6?
