Godlike
Claude C. Kenni (Star Ocean: The Second Story) v Riou (Suikoden II): Nulls light.
Seymour (Final Fantasy X) v Albedo (Xenosaga Series): Gut. I dunno which form of Albedo I vote on but I sorta expect Seymour to be able to handle either. EDIT: No, 1 wins. Vote switched to abstain.
Yuri Hyuga (Shadow Hearts Series) v
Jenna Angel (Digital Devil Saga): Pretty sure we've seen this before?
Heavy
Arngrim (Valkyrie Profile Series) v
Marcello (Dragon Quest VIII: Journey of Cursed King): Looks like Marcello just manages to complete the two-round (Arngrim has 140% MDur or so, Marcello's damage falls in the 70-75 range) and thus avoids getting splattered by Final Blast.
Adelbert Steiner (Final Fantasy IX) v Margulis (Xenosaga: Jenseits von Gut und Bose): Terrible matchup for Margulis, Steiner resists all his damage.
Kary (Final Fantasy) v
Lloyd (Legend of Dragoon): Seems quite unlikely that Kary survives two Wingly Spheres?
Hect (Grandia III) v Emilia (SaGa Frontier): Hect tends to win if given a turn, Emelia damage isn't high enough to prevent this (unless you give her DSC!).
Lans Tartare (Tactics Ogre: Let Us Cling Together) v
Harken (Wild ARMs): My kneejerk is that Maximum Risk being ITD tilts things her way, since a lot of Lans' durability came from good defence. Lans also has physicals and holy magic, neither of which is great here.
Middle
Flay Gunnar (Mana Khemia: Alchemists of Al-Revis) v
Caina (Wild ARMs 2): Strong kneejerk that s/he is just better in the division, though I could be argued.
Gallows Carradine (Wild ARMs 3) v
Graham Cray (Suikoden IV): I... guess the lightning magic should overwhelm the healing?
Hippopressor (Mega Man X: Command Mission) v Lightning (Final Fantasy XIII): ... must start FF13.
Eiko Carol (Final Fantasy IX) v
Alma Beolvue (Final Fantasy Tactics): Still have plenty of Alma respect.
Beatrice (Wild ARMs 3) v
Tifa Lockhart (Final Fantasy VII): Ouch, spoiled. Can block sleep and Beatrice's combination of great durability and shoddy damage means Tifa gets at least a L2 off (possibly a L3?), which is monstrous.
Light
Kid (Chrono Cross) v Rafa Galthana (Final Fantasy Tactics): Can blitz past a healing strategy easily enough, and just outslugs anything else since it's Rafa. Her high hit even spoils Elf Mantle hype! (not that I give that much credibility anyway)
Koroku (Suikoden III) v
Akaghi (Suikoden IV): Kinda opposite ends of the division as far as runeless Suikoscrubs go.
Aeris Gainsborough (Final Fantasy VII) v
Labyrinthia Wordsworth (Wild ARMs XF): There's a very real chance that Aeris literally can't break the distortion...
Evil Gaia (Grandia) v
Mullen (Grandia): Mullen gave the Tonfachallenge a lot of trouble, but Gaia walled it entirely!!! Wait, wrong Gaia form?
Rufus Shinra (Final Fantasy VII) v
Meena Mahabala (Dragon Quest IV): Sadly Rufus is terrible.
