In the two anime I have watched (Bleach and Inuyasha) and the one I have read (Naruto) I find that the main characters are quite alike. I find the main characters, Ichigo in Bleach, Inuyasha in Inuyasha and Naruto in Naruto can seem hard headed and childish outside of battle, but during a battle, they are serious and determined. They all fight to protect something, whether it is someone precious or their pride and they all have a "dark side". What I mean by this is, Ichigo has his inner hollow, Inuyasha has his demon blood and Naruto has the Nine Tailed Demon Fox within him. See? They do have a lot in common.
