Godlike
Heat (DDS) vs Chris Lightfellow (S3): Regenerate's probably not blocked by SL, and that's Chris' only chance.
Violetta (G3) vs Sephiroth (FF7): Same as before. Monkey and Dhyer's views that give Vio the win are both very valid, I just don't hold either. So 2HKOs and isn't 2HKOed.
Heavy
Queen Zeal (CT) vs Alicia (VP2): I'll think about this one some more, but expect it's Alicia's. Alicia will heal right before going into limit phase; Zeal needs to first force Alicia to heal then immediately double with Hallation+poke to finish her off. That's going to be tough for her, especially against somebody with a fair deal of ice resistance available.
Middle
Lin (BoF5) vs Fred Maximilian (S3): Think he 2HKOs.
Light
Oulan (S2) vs Mel (S3): 3HKOs (maybe even 2?), isn't 3HKOed.
Bartre (FE7) vs Titania (FE9): "Doubles lol" was going to be my reaction, then I saw Monkey's vote and rethought: what if Bartre 2HKOs and Titania only 3HKOs? Well, Titania then still wins, because in order for Bartre to 2HKO he'll need both hits to be with a range 1 axe, so Titania is free to double Hand Axe him, not get OHKOed, counter, and kill. Or he starts with a Hand Axe, isn't 2HKOing, and Titania most certainly is 5HKOing.
