It would end up as a draw. Here's why:

(Squall and Sephiroth meet.)
SQUALL: "Are you a Sorceress?"
SEPHIROTH: "I am a lab experiment with the power of the Ancients. Now who are you?"
SQUALL: "None of your business."
SEPHIROTH: "Well, anyway, I hate everything because of that, and I'm going to destroy everything!"
SQUALL: "... Whatever."
SEPHIROTH: "Man, you're so cold. Do you have a girlfriend who I could stab through her back?"
SQUALL: "She's in coma, and I don't care about anything. In addition, there's an idiot called Laguna inside my head, and I just heard he's my father."
SEPHIROTH: "Oh, cry me a river."
SQUALL: "... Whatever."
SEPHIROTH: "Yes."
SQUALL: "..."
SEPHIROTH: "... Do you have an LJ? Let's go post some poems there!"
SQUALL: "Sure."
(They leave together.)
