Godlike
Fou-Lu (Breath of Fire IV) vs Holly (The Wizard of Oz: Beyond the Yellow Brick Road) - o_O!
Julius (Fire Emblem: Genealogy of The Holy War) vs Dialga (Pokémon) - I think the durability edge may be enough?
Yuri Lowell (Tales of Vesperia) vs Rorolina Frixell (Atelier Rorona: The Alchemist of Arland) - Holy crap, what an awesome match. Okay, so Yuri easily one-turns Rorona. Except of course, that his damage is all multi-hit combos, and Rorona auto-heals between hits thanks to her Elixirs. Luckily, Yuri's combo is REALLY long, and since she uses a full Elixir -every time-, she'll eventually run out of Elixirs. The question then is whether she runs out of Elixirs before Yuri's spent up too many hits of the combo to still OHKO her. Because if he -doesn't- one-turn her, she busts out the ridiculous Tera Bomb damage and that's it for Yuri (even if he has something to block Fire, she has a few other OHKOs here). Since Rorona is under average speed, Yuri should go first by any standard DL view, so I'm interested in seeing how many Elixirs people will allow. I personally have been capping Item-users at 10 of any one item for a while now, but this is the first time it's ever mattered. Since Yuri's combo is somewhere in the area of 150(?) hits, I'd say he takes it. But if other DLers are allowing Rorona max Elixirs (I don't know how many this is), it could be significantly closer.
Heavy
Fang (Final Fantasy XIII) vs Brigette 'Rosie' Stark (Valkyria Chronicles) - Grenades are the pretty much the only non-physical damage type in VC from what I've played of it, that's enough for me.
Middle
Eruca (Radiant Historia) vs Hope Estheim (Final Fantasy XIII) - Whelp, I'm convinced.
Hero (Dragon Quest V: Hand of the Heavenly Bride) vs Ledah (Riviera: The Promised Land) - Oh this is just mean. Ledah's awesome, but Fire-reliant and Madason is just loaded with Fire res... Even with Ledah's decent Regen, I think he has too much trouble making the damage stick and forcing a heal-lock.
Stocke (Radiant Historia) vs Yulie Ahtreide (Wild ARMs 4) - If a multi-hitting healer-mage couldn't outslug Eruca fast enough, Yulie really doesn't stand a chance (especially since he can knock her out of her defensive hexes! Cute idea, CK)
Mavelle Foresson (Star Ocean: First Departure) vs Beatrice (Wild ARMs 3) - I don't remember for certain, but I'm pretty sure SO1 has sleep-blockers, and combined with SO1 mage-hype, this is my kneejerk.
Light
Levatte (Eternal Poison) vs Judith (Tales of Vesperia) - simple outslugging, probably doesn't even need the Fatal Strike ID...
Laguna Loire (Final Fantasy VIII) vs Yukari Tekaba (Persona 3) - It's Takeba*, and I guess she chips with Pierce attacks and then Garulas passed Laguna's terrible limit range.
Mukumuku (Suikoden II) vs Swoobat (Pokémon) - *chuckles* No clue, but I'm imagining a cloudrace between them.
