Emily (Suikoden III) vs Edelgard von Hresvelg (Fire Emblem: Three Houses)
Emily doubles and KO's Edelgard. Let's be nice and assume that she doesn't KO, though. Emily's above average HP means that Edelgard needs to connect with with at least 3/4 of her Silver Axe+ counterattack, Raging Storm, and both Brave Axe hits to win round 1. All of which have sub-average Hit, especially Brave Axe+. And Emily is really dodgy. And Emily has one of the best Stun rates and if she procs it Edelgard just loses. Maaaaybe Edelgard can win with only 2 hits if she gets a Crest proc somewhere in there? That can only happen on the Raging Storm though, or if she does a Silver Axe+ Smash rather than a Brave Axe swing. Actually, now that I think about it, Emily's great evasion might very well mean that the +20 Hit on Smash means that counter -> Raging Storm -> Smash is probably the right call here. The 3H killpoint is so high that Edie really needs all 3 to connect though and still no Stun, so.. yeah no. And that's assuming she lives to her own turn!
Heavy
Mazus (Suikoden II) vs Sara Valestein (Trails of Cold Steel)
Well, Sara dies horribly if Mazus ever gets a turn. Purgatorial Flame -> S-Craft -> Purgatorial Flame should be a kill though, if the 70 CT debt Sara incurs from spell -> S-Craft isn't so much as to knock her after Mazus's second turn... the Faint did only last 1 turn, right? I forget, it was 1-turn vs. bosses at least but unsure if it was longer for randos. Anyway, idk about hyping this too much, but Mazus is sufficiently slow that I'm willing to say Sara might just burst him out, but could be convinced - Tide / Random / Dhyer /etc. , any thoughts? (It's 90 CT for the 3 turn damage average with S-Crafts, meaning "turn 2" is around 60-65 CT or so? And Mazus is slow, so he's higher than that? But it's 70 CT minimum, Sara also has the CT spent getting her turn... she might need a longer Faint after all.)
Middle
Oengus (Child of Light) vs Rabbid Peach (Mario + Rabbids Kingdom Battle)
Rabbid Peach needs 5 turns to kill Oengus. Between delay chance and random ID chance, think that's a bit too much time.
Dekar (Lufia II: Rise of the Sinistrals) vs
Hendrik (Dragon Quest XI: Echoes of an Elusive Age)Dekar absolutely cannot stop Hendrik from buffing up to being a massive physical tank and buffing his own offense. It's annoying busting past his IP healing but worst comes to worst, wait for Pep Up which suddenly makes Hendrik fast. Or use Axe defense debuffing too, Hendrik has lots of time here.
Bob (Suikoden II) vs Mae (Fire Emblem Echoes: Shadows of Valentia)
Bob flat OHKO's Mae after transforming, so she only gets one turn.
Light
Mustadio Bunansa (Final Fantasy Tactics) vs Culotte (La Pucelle Tactics)
Culotte kills REALLY SLOWLY. Mustadio... he can't be worse than a 3HKO here, can he? Shoot him once, then spam Arm Aim. Culotte can't just accept a heal lock, so he needs to go aggro, but once Arm Aim hits, Mustadio shoots him twice more and wins. Or hell, even if Mustadio has a 4HKO, that's fine, he might get a double for 3 turns in a row of shooting Culotte after he can't heal.
Tear Grants (Tales of the Abyss) vs Chahn (Cosmic Star Heroine)
Headache. This match takes eons as Tear wants to pressure Chahn than Mystic Arte her, while Chahn wants to build up to a 300% style Burst. Sadly, I'm not sure EITHER of these options will actually kill, and both have theoretically infinite resources (although Tear doesn't like switching to physicals to restore TP). Probably Chahn?
Laguna Liore (Final Fantasy VIII) vs Linhardt von Hevring (Fire Emblem: Three Houses)
Laguna sits around doing nothing. Linhardt's bad damage can't help but knock him into desparation range. If Linhardt refuses to engage, he loses after 100 turns! (Came up in
https://www.youtube.com/watch?v=xGGsnC0Um4c , which was linked recently... Byleth solo couldn't beat Conand Tower in 99 turns, RIP, try again.)
Shady (Wild ARMs 3) vs
Camille (Celestian Tales: Old North)It's Shady.
