Anyone who thinks blood is thicker than water hasn't watched enough anime. The style is loaded with familial brawls, some of which are among the best anime final fights of all time. Because the adversaries share a genetic bond, their issues usually run deeper than the immediate moment, which makes most anime sibling fights feel especially vicious.
In Naruto, Sasuke's attempt to exact revenge on his brother Itachi is incredibly memorable. The pair's final encounter features notably stunning choreography and gorgeous animation, and the potent mixture of love and hatred that exists between the brothers elevates the moment to a new level.
When two relatives square off after a lifetime of disagreements, the resulting fight always carries an additional layer of meaning.
