Godlike
Loki (Valkyrie Profile) vs Citan Uzuki (Xenogears): Indiscriminate fun.
GenocideHeart (SaGa Frontier) vs Dheginsea (Fire Emblem: Radiant Dawn): Oh man Tower against Dheginsea.
Ryu (Breath of Fire III) vs Elincia Riddel Crimea (Fire Emblem Series): Haha.
TimeLord (Saga Frontier) vs Lenneth Valkyrie (Valkyrie Profile Series): Oh wow, this is close. So first, Lenneth MUST block stone and death, but doing so comes at a relatively steep cost of 14% HP and 18% damage (reducing her HP more gets her killed). Still, that's enough to let her one-shot TL after Might Reinforce and survive Overdrive. ... except that TL still goes first after OverDrive wears off, and uses MysticSword or something and wins, I think. I always forget about that attack! Note to self, TL's damage against those who don't get a turn immediately after OverDrive ends = 1.26.
Heavy
Jeremy Non (Wild ARMs 4) vs Wugui (Shadow Hearts): Unloads lots of physical damage into someone who can't evade or counter, and whose gimmick is spoiling magic.
Kiryl (Dragon Quest IV) vs Crono (Crono Trigger): Instant death does its thing.
Selan (Lufia II: Rise of the Sinistrals) vs Time Mage (Final Fantasy V): She's immune to sleep, so Selan's only slim chance of victory is out and she gets pelted by Meteors.
Arnaud G. Vasquez (Wild ARMs 4) vs Hope Estheim (Final Fantasy XIII): Hope has to tank his already bad durability to deal with sleep and death, while Arnaud tanks Hope's magic offence like a champ and laughs at how much better WA4 Slow Down is than FF13 Haste.
Middle
Rudy Roughknight (Wild ARMs) vs Kahn (Breath of Fire IV): Rudy's def lets him survive a focus punch. Kahn does not survive two Rudy turns.
Snow Villiers (Final Fantasy XIII) vs Setzer Gabianni (Final Fantasy VI): Inclined to see dice going through sentinel nonsense, which is pretty bad news for Snow. Still, think Setzer only 4HKOs him on average (dat HP), so he might be able to just 3HKO first?
Lightning Farron (Final Fantasy XIII) vs Vivi Ornitier (Final Fantasy IX): This is close. Lightning 2HKOs and is faster, but Vivi may evade. Theoretically if he evades enough he can do useful things. Problem is he needs to evade at least twice in a 5-attack string, and with his evasion the odds of that are quite bad, while Lightning edges ever closer to a doubleturn which will end the fight. She may also be accruing chain bonus as well.
Light
Franz (Suikoden III) vs Riki (SaGa Frontier): Franz can't heal-lock with a physical, so Heal until Stone Breath lands wins this for Riki.
Joker (Suikoden III) vs Lucia (Shadow Hearts: Covenant): Haha this is great. Okay, so Joker 2HKOs average on the button according to Dhyer's notes. Lucia's magical durability is 100.1%. Yesz. So she isn't 2HKOed and easily kills Joker of the awful pdur before his third turn.
Oulan (Suikoden II) vs Fiona (Fire Emblem: Radiant Dawn): Imbue tilts low-damage matches better than mere good durability does.
Vinsfeld Rhadamanthus (Wild ARMs 2) vs Melody Vilente (Wild ARMs 3): Pretty close, as his HP and Melody's barrier mean they both do similar damage to each other percent-wise. Vinsfeld is a bit faster, and I respect his damage a bit more than the stat topic because I dunno about holding bosses against max possible HP Plus.
