A cold-hearted, ruthless killer from the anime series Naruto
who, at the age of thirteen, thought it necessary to murder nearly his entire clan and mentally scar his then eight-year-old brother Sasuke
in the process---all in order to “test his capacity.”
Generally despised by Sasuke fans.
Generally worshipped by those who believe his sadistic tendency to put people through horrific mental torture is “badass” or “cool.”
Also means "weasel" in Japanese.
Itachi is one sadistic ninja.
