Lelouch Lamperouge, originally known as Lelouch vi Britannia, is the protagonist of the anime series Code Geass: Hangyaku no Lelouch. He is a former prince of the Holy Britannian Empire who becomes an anti-hero revolutionary leader. Disguised as Zero, he leads a rebellion against the oppressive Britannian regime, using his strategic genius and the power of the Geass, which allows him to command anyone to obey his orders. Lelouch's character is defined by his complex morality, his deep love for his sister Nunnally, and his desire to create a peaceful world through his radical actions.
