Godlike
Altima (Final Fantasy Tactics) v Timelord (SaGa Frontier): I think Ovedrive can kill Altima...except it'll only work on one form cause the entire thing resolves THEN Altima shifts forms. And I don't think Timelord is strong enough to take on Form 1 head to head without Overdrive to try and blitz past Form 2.
False Althena (Lunar: Eternal Blue Complete) v Ghaleon (Lunar: Silver Star Story Complete): False Althena's speed edge is offset by Ghaleon's double acting rather well here, and Ghaleon's got a notable edge in durability.
Isolde (Mana Khemia: Alchemists of Al-Revis) v Lenneth (Valkyrie Profile Series): Covered.
Terra Branford (Final Fantasy VI) v Exdeath (Final Fantasy V): First off, I object to allowing Neo-Exdeath on principle that its very clearly NOT Ex-death, but a physical manifestation of the Void using Ex-death's body, so plot fusion and said fusion isn't even really him. That said, Ex-death fails to really shut down Terra at all.
Fang (Final Fantasy XIII) v Chris Lightfellow (Suikoden III): Chris can either Silent Lake, then get out tanked by Fang in Sentinel Mode, or she can not use Silent Lake, and gets Saboteur'd.
Vandesdelca Musto Fende (Tales of the Abyss) v Weisheit (Wild ARMs XF): Kneejerk.
Ballor (Final Fantasy Legend 3) v Fou-Lu (Breath of Fire IV): I can technically vote on this fight, but fuck if I can remember it.
Chaz Ashley (Phantasy Star IV) v Ellen Kirishima (Persona Series): Magic Immunity and Physi Wall works.
Heavy
Red (SaGa Frontier) v Groudon (Pokémon): Good one, kneejerking Groudon here.
Popoi (Secret of Mana) v Ershin (Breath of Fire IV): Equips Lightning, goes first, gets 2 shots of Death in and that should win.
Zalbard (Shining Force II) v Pamela (Mana Khemia: Alchemists of Al-Revis): Didn't he have a strong Ice 2 or something?
Hildegarde Valentine (Shadow Hearts: From the New World) v Elincia Crimea (Fire Emblem: Radiant Dawn): Kneejerk.
Wren (Phantasy Star IV) v Velna (Legaia 2: Duel Saga): Believe he immunes her big tricks, so he just tanks this fight out.
Peppita (Star Ocean: Till the End of Time) v Delita Hyral (Final Fantasy Tactics): Hits hard and all that.
Geddoe(Suikoden III) v Surt (Valkyrie Profile): Surt can take a few hits, so yeah.
Middle
Arche Klein (Tales of Phantasia) v Alice Elliot (Shadow Hearts): Immunes Instant Death, can resist her Magic Damage. I believe that gives Alice the edge.
Yulie Ahtreide (Wild ARMs 4) v Yosuke Hanamura (Persona 4): Not confident on voting on this one.
Nina (Breath of Fire II) v Meg (Fire Emblem: Radiant Dawn): Death.
Albel Nox (Star Ocean: Till the End of Time) v Raven (Tales of Vesperia): Vampiric Flash.
Ashton Anchors (Star Ocean: The Second Story) v Mareg (Grandia II): Scaled, I think Mareg has the edge due to defenses and all that.
Albert Serdio (Legend of Dragoon) v Chisato Madison (Star Ocean: The Second Story): Albert's a tank and hits hard enough, so should just out class Chisato here.
Sara (Breath of Fire) v Charizard (Pokémon): Sure, Charizard is dealing 50% more damage and can get a ridiculously powerful Blast Burn off at low health or something...but Sara's still a freaking end game BoF1 Boss and they just don't die.
Harle (Chrono Cross) v Luke fon Fabre (Tales of the Abyss): Just better.
Light
Serph (Digital Devil Saga) v Shana (Legend of Dragoon): Serph relies on Magic damage that...oh, right, Shana mocks that.
Jogurt (Shining Force) v Augst Henriksen (Wild ARMs 4): ...
Cotton (Saga Frontier) v Relm Arrowny (Final Fantasy VI): Outslugs...
Melody (Wild ARMs 3) v Cream (Sonic Chronicles: The Dark Brotherhood): I think Cream's damage may be bad enough that Melody's barrier completely screws her over -_-
Butterfree (Pokémon) v Alfred Schroedinger (Wild ARMs 3): Butterfree doesn't suck as much in later incarnations or something (pretty sure I allow Gen 4 form since due to HGSS)
Rinoa Heartily (Final Fantasy VIII) v Tim Rhymeless (Wild ARMs 2): I allow Tim fake versions of Gold Mediums that can ONLY be used for Hi-Combine Purposes, since that's a unique trait of his. So that with a lot of pokes from his staff should be able to blast past a Limit from Rinoa pretty easily.
30 foot tall Super Zell Dincht (Final Fantasy VIII) v Seibzhen (Xenogears): Cause I said so.
