シャルル・ジ・ブリタニア

Charles zi Britannia, at first only referred to as The Emperor of Britannia (ブリタニア皇帝), is Lelouch's father, the 98th Emperor of the Holy Britannian Empire, and the principal antagonist of the series. He has 108 different consorts. A strong proponent of Social Darwinism, he views equality as an evil that must be dispelled, and to this end he encourages class conflict and military expansionism so as to maintain social evolution and progress. He also suffered a horrific childhood of his family murdering each other for succession, so he forged a pact with his brother V.V. to create a world without lies. Acquiring allies in Marianne and C.C., Charles created the Sword of Akasha, a weapon designed to facilitate the Ragnarök Connection, remaking the world into a place without lies by killing "God", which is the collective individual unconsciousness of all humankind.

However, when V.V. murdered Marianne and denied his part in her death, Charles was forced to alter the memories of Nunnally before sending her and Lelouch to Japan as political hostages. Since then, the Emperor focused more on his goals while having his remaining children deal with Britannian matters. Eventually after taking V.V.'s code to become immortal, Charles starts up the final preparations of the Ragnarök Connection, revealing the entire truth and that C.C.'s code is the last piece to complete the plan. However, Lelouch sees Charles' ideal world to be nothing more than stagnation that would doom humankind rather than save it, and he uses his Geass to break collective unconsciousness from the connection while having his father dissolve into nothingness. With his last breath, Charles warns Lelouch his rejection of the world he envisioned would only allow Schneizel's to become a reality. /
