Godlike
Terra Branford (Final Fantasy VI) vs Jade (Breath of Fire): Rub's turn 3 at worst, and he's faster.
Claude Kenni (Star Ocean: The Second Story) vs Rubicante (Final Fantasy IV): Fire.
Seymour Guado (Final Fantasy X) vs Cid Raines (Final Fantasy XIII): Seymour has a 3HKO at base here. Quadracast does 48% to Cid, Ultima does 22%. His best bet is Ultima, then quadracast, then two more quadracasts as these will be halved. This lets Cid get off one Ruin x3 and two Seraphic Rays. .. wait, Seraphic Ray is non-typed. Never mind, this analysis is over.
Heavy
Maya Schroedinger (Wild ARMs 3) vs Queen Zeal (Chrono Trigger): Not sure I buy Maya 2HKOing. That's very close to me. I'll think about it.
Alfina (Grandia III) vs Alicia (Valkyrie Profile 2: Silmeria): Blocks paralysis... should be fine from there? Alfina may be able to sneak out a win with Armageddon, but kneejerk is no.
Nina (Breath of Fire) vs Clarissa Arwin (Wild ARMs XF): This is close. Nina will of course use Wall immediately which nulls out Sacrifice (and the resulting counter will hurt Clarissa badly enough to make further Sacrifices weak), so Clarissa is stuck 4HKOing with Howling Shot. Can she set up a Rob Turn chain that lets her win? Uh... probably not, since initiative healing would mess with things too much. The whole "Clarissa against people faster than her" thing... and even if Nina isn't in general, she is at enough things that matter.
Middle
Palom (Final Fantasy IV) vs Elaine (Suikoden III): Ugh.
Hippopressor (Mega Man X: Command Mission) vs Rouge (SaGa Frontier): 5HKOs, has a 5-4, isn't 3HKOed. Kinda sad.
Blanca (Shadow Hearts: Covenant) vs Peter (Shining Force II): You don't survive being heal-locked by Peter, he'll double attack you eventually. Peter's speed only matters for first turn, SH2 has a tight speed curve, so Blanca gets at most one doubleturn before Peter kills him. Since Peter has good HP and isn't weak to wind like Alexia, that's that.
Cleo (Suikoden) vs Etna (Disgaea: Hour of Darkness): For the record, Cleo wins this without the fire rune. She's faster and both 3HKO each other (Etna's close to a 2HKO but misses it), and she's long range to avoid counters. With a fire rune that just becomes a 2HKO on Cleo's end.
Light
Rhys (Fire Emblem Series) vs Tia (Lufia II: Rise of the Sinistrals): uhh surely
Ilyana (Fire Emblem Series) vs Zhuzhen Liu (Shadow Hearts): uhh surely
Rinoa Heartlily (Final Fantasy VIII) vs Milich Oppenheimer (Suikoden): Milich's pdur isn't all that amazing, he more gets hype for having both durabilities unlike most tanks.
