Godlike
Fereydoon (Wild ARMs 5) vs Uryu (Mana Khemia 2: Fall of Alchemy): Uryu has a fairly substantial durability advantage at base, and Fereydoon lacks MT to clean up the gates.
Kartikeya (Wild ARMs 5) vs Mewtwo (Pokémon): Kartikeya wishes his ID wasn't stuck on his one-on-one form, for all that Mewtwo is so fast I'm not sure how easily he could get it off anyway.
Heavy
Caeda (Fire Emblem Series) vs Millenia (Grandia II): Should tank a Caeda turn, then Spellbinding Eye does its thing.
Kloe Rinz (The Legend of Heroes: Trails in the Sky) vs Lilka Eleniak (Wild ARMs 2): Uh... a little help here?
Bacchus D-79 (Star Ocean: The Last Hope) vs Yuffie Kisaragi (Final Fantasy VII): Bacchus has 1.75 pdur, which pretty much laughs at anything Yuffie can do short of a L3 limit, and with Bacchus' offence, the only way she's getting one of those is if you let her interrupt Bacchus' combos in the middle with a limit. I'm not... terribly inclined to do so, as such an interp would pretty much give FF7 free wins over most SO/Tales/etc.
Middle
Cerya Phoraena (Tactics Ogre: Let Us Cling Together) vs Setzer Gabianni (Final Fantasy VI): Hmm. Cerya 3HKOs and... is marginally slower. Which means she should probably just cast Heal at some point, to lap. Or HP Infusion? Either way, the question is whether she can survive 3 Setzer attacks with one shot of healing, and the answer is very likely.
Holly Whyte (Bravely Default) vs Lightning Farron (Final Fantasy XIII): Well they can't break each other's healing! I suppose that means Lightning wins via Odin or something. Or, Holly runs out of MP, since that's apparently possible.
Light
Nope.
