Code Geass: Lelouch of the Rebellion (コードギアス 反逆のルルーシュ Kōdo Giasu: Hangyaku no Rurūshu?) and its sequel series Code Geass: Lelouch of the Rebellion R2 (コードギアス 反逆のルルーシュR2 Kōdo Giasu Hangyaku no Rurūshu Āru Tsū?) are Japanese anime made by Sunrise, directed by Gorō Taniguchi, and written by Ichirō Ōkouchi. The series focus around a former prince of the Holy Britannian Empire, Lelouch Lamperouge, who obtains a mysterious power known as Geass and uses said power to destroy the Holy Britannian Empire, a superpower that controls one third of the world and has recently conquered Japan, and to discover the truth behind his mother's death, as well as the various people that he encounters as he heads toward those goals.
This is a list of characters, minor and major, appearing in both Code Geass: Lelouch of the Rebellion, its sequel series, and/or the core series' spin-offs and products. The fictional characters in Code Geass: Lelouch of the Rebellion were designed by the manga studio Clamp.
During early planning stages, director Gorō Taniguchi contacted the noted manga artist group Clamp, being the first time Clamp had ever been requested to design the characters of an anime series. Clamp signed onto the project early during these development stages and provided numerous ideas, which helped develop the series' setting and characters. Clamp's finalized original character design art, illustrated by its lead artist Mokona, was subsequently converted into animation character designs for the series by Sunrise's character designer Takahiro Kimura, who had previously spent "every day" analyzing Clamp's art and style from their artbooks and manga series. In working on the animation character designs, he focused on designing them so as to enable the series' other animators to apply them without deviating from Clamp's original art style.
