Sorry, this is gonna be long: I have to say that Naruto's so cool because of the potential. Like a lot of other main characters in manga, or whatever, Naruto has the "eye of the tiger" and the "will to survive," or protect others (which is why he WILL become Hokage sooner or later, even if it's posthumously). He also has a competitive spirit. In the beginning of the story, he just wanted to beat Sasuke, and become Hokage. He never gives up on trying to accomplish his goals (kids, take notes for life), but most people think what sets him apart is not only the 9-tails, which gives him vast chakra reserves, more than anybody else has. I say, "Yeah, but..." The coolest thing is the world and possiblities that Kishi has imagined. Basically, everybody's a magician (except for civilians and Lee, who by the way is a bad-ass, as well), and there is NO limit to what can be done. Just look at the idea that each generation surpasses the previous ones. The whole thing just has to be organized to where it builds and builds on itself to a climax, or faux-climax, where it dies off (fillers or whatever) when it starts the cycle again, just on a higher level. I hear Naruto was inspired at least in part by Dragonball Z. I don't know if it's true, but I believe it (Get it? Naruto always says, or used to say, "Believe it!" Sorry, just some of my stupid humor and rambling on.). There was NO limit to what Goku could do. If the bad guys kept getting better, and unlike in Bleach, as far as I'm concerned, EXPONENTIALLY better, Goku would rise to the challenge, and unveil some new super technique or level he's reached. I totally see that in this. Bleach, not to be hating, because I do read it and am entertained, doesn't even come close to the cool things that Naruto and the gang does. I didn't even touch on how there're soooo many different characters with different styles and abilities, which they build on as well. Is anybody still reading this? I kept going on and on, and using run-on sentences.
