Biography:

Cornelia li Britannia is the second princess of the Holy Britannian Empire, as well as the Commander-in-Chief of the Britannian Military. She is an expert in Knightmare Frame combat, as is shown by her conquest of the Middle East, which became Area 18, before she came to Area 11. Close by her side is her personal knight Gilbert GP Guilford, known as the Spearhead of the Empire, and General Darlton.

When she first arrives in Area 11, she launches a military campaign against all terrorists, namely the Japanese Liberation Front. Starting with the ghettos, she erases all traces of terrorists with her ruthless strategies. Lelouch tries to infiltrate her army, but his strategy is proven ineffective, and was about to be caught, until Zero (CC in disguise at the time) appears, causing a distraction. With that golden chance, Lelouch makes his escape. It is that defeat that caused Lelouch to form the Black Knights.

Cornelia dotes on her sister, Euphemia, her only known weakness. Zero exploits that weakness when he finds out that Euphemia was captured by terorrists. As Zero was about to enter the hotel, he asks Cornelia, "Which do you choose, the Clovis who is dead, or Euphemia who is still alive?" She did not give an answer, and thus, let Zero pass through the gates.

Corenlia then launches a full-scale surprise attack on their headquarters on Mt. Narita. The Black Knights uses this chance to make their move, as Zero has everything planned out. As the Britannian military was winning against the JLF, Zero causes a giant mudslide, destroying much of her forces. While secluded, she was about ot be captured by the Black Knights, until Suzaku rescues her. At first, she had doubts about the abilities of Elevens, but under the circumstances, she had to accept the fact that Suzaku's abilities are of a different caliper.

Being worried about Euphemia, she asks her to take on a personal knight. However, Cornelia did not agree with the fact that she took Suzaku Kururugi, an honorary Britannian, as her personal knight. This caused much controversy in the ranks. Euphemia's reputation is further questioned when she establishes the Special Administrative Region of Japan, something that the Elevens liked at first.

Somehow, intuitively, she knew that Zero was Lelouch, and asks that they work together. Zero agrees, and their plan was about to work, until his geass goes out of control, causing him to "accidentally" command Euphemia to kill all Japanese. Euphemia resists, of course, but geass commands are absolute, and she orders that all Japanese are killed. After Euphemia's death, Cornelia is grief stricken and stays silent for while. During the final battle, Cornelia and Zero had their showdown, but she was defeated by Darlton's surprise attack, under the influence of Lelouch's geass. Lelouch uses geass on her to explain his mother's death, only to find out that Cornelia knew nothing.

In the second season, Cornelia wanders about, searching for answers that might clear Euphemia's name. She found the Geass Directorate, and killed several scientists, but is captured by the immortal VV. When the Black Knights attack the Directorate, Cornelia aides their assuault on VV with an Akatusuki. After that, she is captured by Zero and secrelty held captive until her rescue by Schneizel.
