(1) Squall vs. Seifer
(8) Laharl vs. Mid-Boss
Squall rules in KH, and the opening FFVIII cinematic is awesome. Don't ask me what I think about the actual game; haven't played it yet.
(4) Siegfried vs. Nightmare
(5) Ramza vs. Delita
I imagined myself flipping a coin for this.
(3) Dante vs. Vergil
(6) Sol Badguy vs. Ky Kiske
Carried entirely by DMC1, the only one in the series I've played. Easily enough.
(2) Sora vs. Riku
(7) B.J. Blazkowicz vs. Adolf
Sora/Riku is cornier than Nebraska, but I've always loved it.
