Godlike:
Ghaleon (Lunars) vs Odd Eye (SF2)- Odd Eye might have an argument with double Odd Eye beam? Or did he run out of MP?
Rhapthorne (DQ8) vs False Althena (Lunar:EBC)
Ryu (BoF4) vs Cecilia Lyne Adelhyde (WA1)- Unsure here. Ryu has 6 turns in his status immune dragon, and less if Cecilia buffs her speed and he wants to Sanctuary. He needs to double before then. He probably takes it, but I need to math it out. Granted, if I'd see Sanctuary as magic, then after she buffs speed, he can't really win. Oh right, I also guess that if WA MP draining limits WA enemy MP attacking capabilities and Ryu is only immune to the gravity versions, Cecilia also has another plus that way.
Lavos (CT) vs Heat (DDS)- Unsure. Lavos hates losing his first turn, but has pretty strong Lightning magic.
Heavy:
Jack van Burace (WA1) vs Lin (BoF5)- Jack. Faster, and Lin can't block ID and Paralysis.
Cristo (DQ4) vs Id (XG)- Double Deathblow and then double ether after Cristo buffs.
Saturos (GS) vs Zeno (BoF5)
Nel Zelpher (SO3) vs Angela (SD3)- Faster+Freeze cahin.
Middle:
Ahihiko Sanada (P3) vs Marle [Nadia Guardia] (CT)- Status
Titania (FE9) vs Paine (FFX-2)- No free shortrange counters gives Paine a pretty easy win here.
Ena (FE9) vs Kornell (G3)- Lots of AoE bombardment works here (As does WoW to get around some of her defense at least).
Eiko Carol (FF9) vs Magdalen Harts (ACF)- 2HKOs, faster, Eiko doesn't have scary turn 1 status.
Light:
Noel Chandler (SO2) vs Rozalin (Dis2)- Noel has so many shots of 50% healing. Rozalin game-worst damage can't kill deal with that.
Hanako (Dis2) vs Anna Ziriski (PS2)
Cleo (S1) vs Yukari Takeba (Pers3)
Kid (CC) vs Peco (BoF3) - Can even absorb Fire to make Kid sadder!
