Uchiha Madara is a very powerful character in "Naruto". Here are some of his classic quotes:

-Power is different from will, it is the interaction between substances.

-No adult would get angry with a child.

-This kind of chakra, I recognize you. In terms of physical skills, among those who have fought against me, no one is better than you. I, Madara, would like to call you the strongest!

-Love is not necessary. Power is the only real necessity.
