Godlike
Emelious (Grandia III) vs Reicher (Mana Khemia 2: Fall of Alchemy): More evasion whoring.
Heavy
Jowy Atreides (Suikoden II) vs Vayne Aurelius (Mana Khemia: Alchemists of Al Revis): Jowy just OHKOs Vayne. He's not especially magically durable.
Kluke (Blue Dragon) vs Ceodore Harvey (Final Fantasy IV: The After Years): Not 100% sure here, but... well, if Reflect blocks Kluke's entire skillset, Ceodore obviously wins. Even if he doesn't, he should just survive a max charge Shadowus, so he can afford to Haste + heal + buff with Float (Float shuts down the attack with the biggest argument to piercing reflect). Awaken gives him one shot of healing after Reflect, too.
Middle
Tengaar (Suikoden Series) vs Brad Evans (Wild ARMs 2): Straightforward.
Rina (Suikoden II) vs Jiro (Blue Dragon): Very close, but I think so. Rina is faster, but needs like 10 turns to double, so she'll run out of things stronger than her physical to heal-lock with. The physical -> Explosion is a heal-lock, I think, barely... but I don't have to calc this since Jiro can escape a borderline heal-lock by casting regen. Oh yeah, he might also get Corporeal before that doubleturn happens, anyway.
Light
Volug (Fire Emblem: Radiant Dawn) vs LeBlanc (Final Fantasy X-2): If blind is as good as it is in FFX, Leblanc takes this. Otherwise... I dunno. Anyone know?
