Itachi...whilst i don't like him as much as i did Zabuza...is still without a doubt THE most powerful enemy introduced so far...i mean, come on! The guy single handedly wiped out the ENTIRE Uchiha clan bar Sasuke...and who knows, he may even have a summoning technique...i think ultimately Itachi will be killed....just wondering...will it be as depressing as the death of Zabuza? Afterall, family-killer or no family-killer, Itachi is sasuke's brother.
