Godlike
Garm (Valkyrie Profile: Covenant of the Plume) vs Lady (Shadow Hearts: From the New World): There's that overkill MT.
Guv (Dragon Quest VIII: Journey of the Cursed King) vs Violetta (Grandia III): Is Stream Killer melee? Match seems to hinge on that.
Heavy
Jowy (Suikoden II) vs Tidus (Final Fantasy X): OHKOs very easily, definitely isn't blitzed out before then.
Light
Volug (Fire Emblem: Radiant Dawn) vs Mightyena (Pokémon): Hmm. Volug probably wants to Halfshift here. He 5HKOs after Intimidate, while Mightyena 3HKOs him. But Mightyena triggers counters, so the 5HKO happens first when combined with Volug's greater initiative. Granted, Mightyena has Scary Face, but this... doesn't let him sneak a second double in before Volug's third turn. However, when combined with SAND ATTACK as the second action, we get... V-M-M-V-M-V-M-M. That's enough for Mightyena to win, provided one of Volug's four attacks miss, and one should. Good fight!
