pretty much anyone... knowing the speed advantage is on Naruto side... but equalize speed and Darth Vader STOMPS... cuz his a BADASS
I don't think the speed is equal, so I'm pretty sure Naruto has the sufficient speed.
I'm not really sure. Renamon is fast enough to dodge any curse or general offensive attack by Voldermort but she wouldn't dare be able to get close enough to him to attack and any of her long distance stuff can be blocked by charms. Could go either way really.
