Godlike
Ashera (Fire Emblem: Radiant Dawn) vs Yuna (Final Fantasy X) - Yeah, summon, death.
Orgulla (Xenosaga: Jenseits von Gut und Bose) vs Rubicante (Final Fantasy IV) - Mmmm...so, Orgulla is close to 30x durability to me. RubiCAN is more like 10x. Orgulla hits 4x weakness with physicals, which...means each hit is 1.4x HP. RubiCAN deals 2x with a 2x weakness which puts him at...4x HP damage. So wow, this is...really close. So RubiCAN kills in ~8 actions, Orgulla kills in ~8 as well...and she's faster, but misses a turn to switch to Manes! So straight up, RubiCAN wins...except that Medica, Quick, and attacking things in uber-fast Eryu mode...wins it with her durability advantage. Close as hell, honestly, but the lack of fire weakness with Medica and Quick helps her a ton. Random switches to Manes/Eryu might make a difference?
Heavy
Lady Harken (Wild ARMs) vs Lilka Eleniak (Wild ARMs 2) - No EXAing, so...man, enough defense boosting and she'll be ok. But...no, don't see her damage killing Harken. Too much pressure, forces heal-lock even with buffing. Give it to the one that keeps doing damage - if Lilka doesn't heal, she gets killed.
Oerba Yun Fang (Final Fantasy XIII) vs Lucian (Valkyrie Profile) - I suppose.
Middle
Stocke (Radiant Historia) vs Red XIII (Final Fantasy VII) - FULL LIMITS
Odessa Silverberg (Suikoden) vs Rauny Vinzalf (Ogre Battle: March of the Black Queen) - I do agree that temps should be taken when they leave (but, I mean, it's not hard to reverse engineer and think back that far). "Valid" as a note is very subjective, as there's been precedent for temp vs. endgame for those types of characters before - best to have all the notes possible, which aren't too hard to make. Taking her as a temp...makes her awesome, since I don't think runes were buyable at that point (matters to me, since I allow purchasing storeboughts), and she shreds things hard. Taken at endgame, she's ok, but still probably serviceable enough for this?
Light
White Mage (Bravely Default) vs Ace (Suikoden III) - RUNES
Aguro (Lufia & The Fortress of Doom) vs Marivel Armitage (Wild ARMs 2) - Really need to get to taking Lufia temp stats at some point - I imagine Aguro doesn't look as good when Lufia is taken out of the averages? Does Guillotine hit before dying? Marivel is far faster (97% speed vs. 80%), Aguro deals 1.09% average damage. Marivel is 90% HP, so he...kills in 3 shots. So 3 shots should be enough...now, if you include HP Up in the averages, she dies way faster (2-shotted), although could she kill on damage? No...no she can't. So...yeah, being faster is the thing here.
