Godlike:
Jade Curtiss (TotA - Cheagle Woods form) vs. E.V.E. (EBO): Better at everything.
Ghaleon (LSSSC - PC form only) vs. Goku (DBZ:LotSS): So much faster its not even funny. That, and Ghaleon is a real temp, Goku is mostly just a "PC with limited use"
Giffca (FE9 form ONLY!) vs. Croix (LP:T - the level 100 solo fight in the past): Seemed a lot stronger offhand. Didn't he also have fire damage?
Sesshoumaru (Inuyasha RPG) vs. Valkyrie (VP2): AHAHAHAHAHAHA, no. Sesshy is better than Valkyrie at everything.
Heavy:
Orson (FE8 - chapter 5x form only for this) vs. Seth (PS4 - PC form only for this): I think Deathspell wins this?
Dark Knight Cecil (FF4) vs. Odessa Silverburg (S1): Instant Death, don't think Odessa can stop this from coming off.
Alys (PS4 - PC form only >_>) vs. Jowy Atreides (S2): OHKOs soundly, Alys doesn't hit him with Death turn 1 to me.
Ellen (P2 - Nike only) vs. Seymour (FFX - PC form only): Was about to vote Ellen until I realized its P2 form, which apparently isn't magic Immune, so...no vote!
Middle:
Bosch (BoF5 - only the PC form for this) vs. Yang (FF4 - original PC form only for this): Bosch should be in Heavy. Don't try to pretend anything less. Completely crushes Ryu in everyway during that time.
Shinjiro Aragaki (P3) vs. Milda (G1): Can't vote.
Minwu/du/whatever (FF2 - Main Game form) vs. Young Teepo (BoF3): If nothing else, he has lots of tricks. Among them include an evasion buff spell and a damage reduction spell.
Alonso (G3) vs. Seena (L3): Think he heal locks her with a physical while having a tech ready.
Light:
Miranda (G3) vs. Sue (G1): Sue was pretty clearly LVP when she left, Miranda not so much.
Ted (S1 form only) vs. Samson (AtL4): This fight fails.
Hien (SH2 - PC form only) vs. Aeris (FF7): As does this! I think just having a bit of a second wind with healing limits (no pun intended) is enough to beat Hien...maybe.
Sr-1 (BoF1) vs. Jenna (GS1 form only): Sr-1's damage was good for the time!
