Godlike:
Fou-Lu (BoF4 - only the PC form for this) vs. Jade Curtiss (TotA - only the form before reaching the Tartarus, i.e., the Cheagle Woods form): Can't vote.
Mr. S (FFL2) vs. E.V.E. (EBO): E.V.E. is far more ridiculous than Mr. S. I'm not even sure she has an actual HP score of which to die with <.<
Heavy:
Laike (Lunar1) vs. Orson (FE8 - chapter 5x form only for this): I'm gonna go with "Counters = Win" here. Yeah, that works for me or something (didn't he also have a Silver Sword which is absolutely sick for the time too?)
Dekar (Lufia 2) vs. Seth (PS4 - PC form only for this): First off, I just wanna say you don't need to say "PC Form Only" since there is only one character named Seth in PS4!
...on a more important note, think this fight is just "Seth goes first, casts Death Spell, Dekar dies."
Middle:
Bosch (BoF5 - only the PC form for this) vs. Keifer (DQ7): Why is Bosch not in heavy? He completely creams Ryu in every stat so badly its not even funny, and then has killer damage too.
Yang (FF4 - original PC form only for this) vs. Seifer (FF8 - PC form only for this): Puts Seifer to sleep, spams Endure until his defense is jacked to hell, reapply sleep if necessary. Yes, FF4 stat buffs stack, they just suck too much that you really need to use them a lot for it to work (like have some good stalling tactic.)
(for what its worth, Yang doesn't need Endure anyway; his damage for the time was relatively better than it would be endgame!)
Light:
Miranda (G3) vs. Tempest (Lunar1): Tempest sucks.
Sue (G1) vs. Galvan (LoL2): Isn't Galvan more of a middle? He owns Lang in like everything, IIRC, if only slightly. Sue just sucks, no, I am not hyping Rah Rah as giving her the fight.
