Kenshin would win if it was up to the swords and combat skills alone. Ichigo would probably win if powers got involved since for all that Kenshin is awesome, he is only human... (I still voted for Kenshin though! ^^)
I know this is a bit odd, but if you don't mind me cluttering the thread with something a bit extraneous (though somewhat related) I'd like to post the link to a literate Kenshin roleplay forum that a friend of mine is starting. (So far, the character of Kenshin is still available! And original characters are welcome.
3nodding ) The only thing aspect of the forum that differs from the series is that the Meiji revolution is happening with modern Japanese technology and culture but Meiji era weapons. (If that didn't make any sense at all, I suggest checking the link out since my friend explains it far better than I.) Thanks and I hope you check it out!
