Lelouch Lamperouge is the protagonist of Knightmare Battle Tournament! and is also the leader of a Knightmare Battle Squadron named the Black Knights.
Lelouch looks similar to his father, despite being years younger. He has ebony hair and violet eyes that he and his sister have gained through Alexandria's Genesis, a mutation known to give the subject pale skin, purple eyes, and lack of body hair aside from the head and eyebrows. He is tall and handsome, causing him to gain a large fanbase at his school. He usually has a bored and stoic expression, which changes depending on the situation.
Lelouch is very kind and caring for his friends and especially for his family due to the fact that his sister is all he has left. He is overprotective and will be willing to do anything for Nunnally. To add to this he is very intelligent, however lazy when it comes to physical activities or school work. He is also bored in most situations that involve him unless he can gain something out of it, in which he becomes very evil and devilish. Despite his dark side, he is still easy to get along with and a very popular person at Ashford Academy.
