Who is your favorite character? Not by just appearance but for what they have done, their accomplishments and the reason they have done so.
My favorite is Obito/Tobi due to the fact that he has ochestrated all that we have seen, such as giving kakashi his sharingan thus making kakashi one of the strongest shinobi. then attacking the hidden leaf with the nine tails and causing naruto to be the jinchuriki. then the formation of akatsuki making it possible for many other fucked up things to happen. and then declaring war on the whole world for the want of being with his lover i mea shit thats dedication. and if u think about it he is similar to naruto, going above and beyond for the ones that he loves.
