Godlike
Ice Queen Avril (Wild ARMs 5) vs Cloud of Darkness (Final Fantasy III): Boss with durability edge, I wanna say.
Arceus (Pokemon) vs Myria (Breath of Fire Series): Ok, at first, BoF3 form wins this. If you vote based off that, ignore this entire thing, as I am going from a BoF1 perspective. The description is below, mind.
Emperor (Final Fantasy II) vs Yunalesca (Final Fantasy X): Absorb hype or something.
'Zenon' (Disgaea 2: Cursed Memories) vs Dark Dragon (Final Fantasy Tactics: War of the Lions): Can't vote...at all.
Heavy
Darkrai (Pokemon) vs Ash (Phantom Brave): Can't vote.
Sabin Rene Figaro (Final Fantasy VI) vs Lilka Eleniak (Wild ARMs 2): Think she eventually wins by stalling.
Ull (Valkyrie Profile 2: Silmeria) vs Justin (Grandia): Heal is the perfect thing to use on people with limited resources, as is having actual boss HP.
Freyjadour Falenas (Suikoden V) vs Ultros (Final Fantasy VI): Faster, so 2 tentacles should kill.
Middle
Masaki Ando (Super Robot Taisen Series) vs Sara (Breath of Fire): The form I know, Sara kind of slaughters, I think.
Aigis (Persona 3) vs Elsa Elliot (Front Mission 4): Can't vote.
Carol Anderson (Wild ARMs 5) vs Yulie Ahtreide (Wild ARMs 4): Kneejerk.
Prier (La Pucelle: Tactics) vs Jeanne (Jeanne D'Arc): Can't vote.
Light
Relm Arrowny (Final Fantasy VI) vs Scholar (Final Fantasy III): Scholar is basically Relm with worse equips, but an actual skillset. Winning trade in this fight.
Rogue Tomato (Final Fantasy XII) vs Edward Damcyan (Final Fantasy IV): -_-
Combee (Pokemon) vs Straybow (Live a Live): Combee. I don't care about how Straybow really is (for better or worse), "Its Combee" is the underlying argument here and yeah...
Sailor Moon (Sailor Moon: Another Story) vs Shinon (Fire Emblem Series): Shinon doesn't fail as much as he should end game *Grumbles*

ARCEUS VS. MYRIA ANALYSIS:
Arceus' Set Up:
Ghost Plate (Makes him Ghost type, thus immune to physicals, at least from my perspective.)
NOTE: He still has Rock and Steel forms as well, which, from some perspectives, halve physical damage. You could argue Steel even halves Big Crash since Steel tends to resist a lot more than it neutrals AND is weak to combined.
Judgment
Earth Power
Recover
Filler (Cosmic Power works, I guess, or something like Hyper Voice for extra damage.)
Ok, when I did this analysis, I thought Judgment was only 5 PP, not 10, so he needed as much extra damage as possible...then I realized how much alternative Magic Damages he had between Earth Power, Hyper Voice, and Hyper Beam, and realized that wouldn't be the case. In any event...
Myria's faster, HOWEVER, Arceus is still damn fast himself, so Myria's not consistently double turning him; maybe a 5/4 split? That seems reasonable; I peg Myria's speed at about 170% in any event. Point is, at best, Myria has a 4/3 split.
Ghost = Physical Immunity argument in tact (which I'm assuming for this), Myria's ONLY source of damage on Arceus is Big Crash. A godly 70 damage to 200~ HP. So that's a 3HKO...to Arceus' 1.76 durability. Now its a high 6HKO. This means Arceus can get plenty of turns to attack between healing. It'll take Myria 5 of her turns to force Arceus to use his first recover, so that's 4 Earth Powers used on her. From there, it alternates.
Somewhere in the mix, Earth Power is likely to lower Myria's special defense (10 shots of 10% chance.) This boosts Judgment's damage. The earlier it happens, the better, asit means Arceus swaps to the far stronger Judgment. I think before Arceus runs out of recover, he's doing over 4 digits of Pokemon damage. I...don't think even Myria can survive that.
Now, to insure Arceus lives longer? He can open with Cosmic Power. That turns the 3HKO vs. average into a 9HKO (albeit, the opening Big Crash is hitting him at default, so its still doing high 6HKO damage there.)
So...yeah, I think Arceus wins this. However, I have to decide if "BoF3 form wins regardless" is a good enough here. For the record, BoF3 Form has a simple case of "Cast some status spell, it hits before Arceus kills, win!" Its times like this Arceus wishes Refresh was Safeguard (then it'd be a neat match! That Myria still probably wins?)
