Corrin (Fire Emblem: Fates) vs MOMO (Xenosaga Series)
BR or RV Corrin should easily just kill XS3 MOMO before she gets a turn (which is what she was nom'd as). XS1 MOMO might avoid the double... but her sleep was apparently only against AGWS? This just gets her Draconic Hex'd and heal-locked, even by CQ Corrin. But I allow RV anyway which makes this easy.
Camilla (Fire Emblem: Fates) vs Lawfer (Valkyrie Profile)
Malig Knight / Wyvern Lord move is pretty great, so inclined to see Camilla get the drop on finishing her 2HKO first. Also WTA!!1!
Ryoma (Fire Emblem: Fates) vs Kika (Suikoden IV)
Think Kika needs to either double or have both Falcon Runes hit. Possible but sketchy.
EDIT:
Rowen J. Ilbert (Tales of Xillia) vs Nelis (Suikoden V)
EDIT: uh sure I guess I can vote on this, but yeah, Fire res is usually good vs. Nelis.
Light
Soleil (Fire Emblem: Fates) vs Olivia (Fire Emblem Awakening)
Olivia is not very good.
Atusro Kihara (Shin Megami Tensei: Devil Survivor) vs Lilianne Valendorf (Mana Khemia 2: Fall of Alchemy)
Poor Atsuro.
Volk (Arc the Lad: Twilight of the Spirits) vs Lucius (Fire Emblem: Blazing Sword)
Power Loss sounds busted for Light, but it'd be going up against Lucius's RES, so probably not.
EDIT: To talk about this a bit more, AtL4 is a bit of a wacky game because, like Grandia 1, regular enemies are kinda dire. I tried a solo "challenge" playthrough after I beat it, and it's actually even more brainless, because merely going a little overlevel ALSO reduces enemy damage to chip damage. Makes it really hard to gague status / debuff hype, since only bosses can sanely kill you, and they generally immune it anyway... well, I assume.
