No Lunar 2 or SoA, no... Disgaea 1, though I probably could just stat topic that. No G3, no CStW, no Xenosaga, no PS4, no P4, no Lufia2, no FE, no SuikoT, no MK2, no MMX:CM, no WA:XF,
Godlike
Lamington (Disgaea: Hour of Darkness) vs Yaridovich (Super Mario RPG: Legend of the Seven Stars) - Willy Wisp should be enough.
Heavy
Max (Shining Force) vs Marle (Chrono Trigger) - Copy and paste from what I posted in DL chat: I just did a bunch of math for Marle vs. Max, and all I could really come with is that not only does she need people to not see her as OHKOed (and she can barely do it!... With I think single-digit HP left - Marle's ~72% PHYeHP if I did my math right to Max's 71% PCHP damage) while a SonicArrow Slow activation procs on turn one, have her lap into a Cure 2, and then just cycle between Provoke, arrow plinks, Haste... And after a point my eyes started going cross at the question on whether or not getting hit under Provoke resets a character's ATB, and if Marle would even have the resources to win anyway. Nevermind, the formula I was using for Marle's PHYeHP was flawed anyway, Max OHKOs here.
Middle
Ricardo Gomez (Shadow Hearts: From the New World) vs Venusaur (Pokémon) - The one fatal status Ricardo can't block: a forced nap!
Light
Ilyana (Fire Emblem Series) vs Paula (Earthbound) - Damage reflection happens before Dispel, and Ilyana is all magic? Regardless, Paula is faster, Ilyana doesn't double, and can't stall out Paula, since Paula can just waste turns with PSI Magnet (for all the good it does her) or put up a new shield.
Logg (Suikoden V) vs Gordon (Disgaea: Hour of Darkness) - The exact math makes my head hurt, but I'm going to go ahead and say Logg because six shots of healing should trump whatever resources Gordon has, even with counters.
