Godlike:
Indalecio (SO2) vs. Etna (Dis): I'm taking Etna's power with a bit of a grain of salt given the nature of Disgaea and its tongue and cheekness; Indalecio coming from a serious setting as such gives him the edge.
Siegfried (WA1,3) vs. Mithos Yggdrasil (ToS): Siggy is *NOT* a Plot Godlike. WA3 goes out of its way to indicate he's not this invincible warrior (Maya holds up well against him, if ultimately losing for example), and he's not even the strongest Quarter Knight in WA1 (the game states Berserk is the most powerful outright, Siggy's just the leader.)
Wiegraf/Velius (FFT) vs. Lady (SH3): Whatever.
Feena (G1) vs. Ashley Winchester (WA2): I'm assuming Sword Saint powers allowed him which...uh, yeah, kind of crush Feena. Feena's power isn't much in Godlike anyway. Leena, whose probably more powerful showed one instance of immense power and...it pretty much killed her (then she was Deus Ex Machinaed back to life); having to sacrifice yourself for immense power doesn't really help much.
Heavy:
Ziggurat 8 (XS) vs. Hector (FE7): Armads is about the only thing he has going for him; flipside, XS does hype Ziggy to some extent, saying his Cyborgness makes him bad ass.
Randi (SoM) vs. Lenna (FF5): GOing with Crystals > Mana Sword for now. Neither are heavy to me, since its all "CHOSEN WARRIORS!" but that's about it.
Maria Traydor (SO3) vs. Emeralda (XG): CK's logic works for me. Maria's Power is kind of worthless in that regard outside of the Eternal SPhere; her power outside the Eternal Sphere was letting the party actually exist as though they were reality, and not holograms, from what I understand (while Fayt's Power let them stand up to the Executioners where warships were being obliterated, I wanna say?) That...doesn't really do a lot against a nanomachine killing...uh...machine.
Irvine Kinneas (FF8) vs. Cherenkov (XS): What is Irvine doing in Heavy? Yeah, Sniper...but it kind of ends there. Fuck, I'd struggle to put Squall in Heavy and he's about the best of SeeD you'll get and they're elite mercenaries, fuck if Irvine gets that high. Flipside, Cherenkov has shown some impressive display of powers that'd be enough to kill someone like Irvine.
Middle:
Minsc (BGs) vs. Zhuzhen (SH): The Hamster is the tie break *nods*
Kevin (SD3) vs. Kimahri Ronso (FFX): Ok, this is just O_o. Irvine gets Heavy but Kevin gets Middle? Even though Kevin is...suppose to be like the strongest warrior of the entire Beast Kingdom with the exception of his father? A Kingdom known to be filled with bad asses and all that? And Kimhari's no slouch either...both would lose to Cherenkov admittedly, but point is, this is kind of weird. Anyway, Kimhari's strong but how strong is up to debate; Kevin's suppose to be incredibly bad ass once he gets past his pacifistic tendencies (which he does in game.)
Arche Klein (ToP) vs. Zahaak (S5): Arche is a Plot Heavy. ToP goes out of its way to say Half Elves are bad ass and its cause their power is so frightful that they were banned from Ymir.
Rico Banderas (XG) vs. Raine Sage (ToS): If nothing else, Rico is built for fighting, Raine is not. Half Elves in ToS weren't hyped the same way as ToP Half Elves, so Raine doesn't benefit in that way.
Light:
Banon (FF6) vs. Charmles (DQ8): Banon is leader of the Returners, admittedly, this is mostly cause of leadership skills and has nothing to do with fighting...but for fucks sake, its enough to beat Charmles, I'm sure of THAT much.
Mogu (BoF) vs. Scarlet (FF7): Mogu is a warrior, Scarlet is not; yeah, that works.
Roger S. Huxley (SO3) vs. Edward (FF4): Edward is a total pansy; adventurous kid > Bard who angsts and can barely fend for himself.
Serra (FE7) vs. Healie (DW4): ...well, at least this entire field looks like Light <_<
