To whoever said Ansem was a Disney character . . .
Psyco! Ansem was designed by SE (COMPLETELY BY SE)!
An-e-ways . . . they're both KOOL . . .
NOT A POLL! AN ABVIOUS ANSWER
Sephiroth was a pathetic character in KH his personality was so shallow. It only takes a few sentences to describe it. Duel Sora, I think I'm so good by casting Death on him (not duelign anyway!). See, how lame of him. And he should've been difficult as he was SUPPOSED TO be the hardest battle. Well, he might have been if all bosses weren't such a breeze. Kurt Zisa was the best boss along with The Phantom!
Ansem was bad A$$ to the max! Where as Sephy was a wimp who was just a lost as Squall in his own mind. Sad, sad, sad. The vote is obvious in my opinon. Ansem is darkness. Explain how anyone can defeat something that never dies. Go on explain....
But first what would most likely happen. Sephiroth comes from his own world and challenges Ansem to a duel (like with Sora), they then start the battle. Sephiroth does his pathetic Berserk like moves (which are so unoriginal and gay), and swings around like mad all the while Ansem uses the "power of darkness" to simply engulf Sephiroth. Of course Sephiroth teleports behind Ansem to start succeeding. Now like most people have said they make it sound like Ansem would just sit there. HELLO! He'd fight back. Since it is a duel you could trust Ansem not to cheat but not Sephy. Sephy would occasionly cast Death on Ansem, which would have no effect. Ansem who likes to teach others wouldn't cheat like Sephy does with Death and he'd use his own strength. Using the dark balls (sorta cheating i suppose) to wring HP off of Sephy instantly. He would them use his long (i think it was a lance) to whack Sephy around a bit. All the while the same would be happenign to Ansem.
The winner would be no-one. A draw is instant. but if it weren't for Sephy's pathetic and childish move Death he might just win. I voted Ansem because he is cool and doesn't dress like a freakin' pyscho that Sephy really is.
