Middle:
White Mage (FF3) vs Don Mole (DQ8)- WW offense can't be THAT epic.
Rozalin (Dis2) vs Knight (FFT)- Weapon Break. Or probably just outslugs, Knight is decent against physicals. This is the type of fight that makes me want to consider range though. Blech. Roz would destroy Knight in either game's combat systems.
Light:
Allen Ridgley (XS3) vs Psyduck (PKMN)- It's Allen.
