I accept your challenge. First off, imagin are unpredictable. You can't fight something well if you can't see it coming. Kabuto is at a downside there. Second of, CLOCK UP and HYPER CLOCK UP. These are Kabuto's best weapons, but it can't just be counted as an instant win. If Den-O can get to the Den Liner before Kabuto kills him, he can go back in time and attempt to stop Kabuto getting the Zecter. Kabuto can follow his as Hyper Kabuto, but if Den-O uses his finisher on him just as he arrives, Kabuto is down.

This is about the only circumstance I can come up with, so now I'm thinking I should've voted Kabuto. Him versus OOO would be interesing.
