Marianne vi Britannia

Marianne vi Britannia (マリアンヌ・ヴィ・ブリタニア, Mariannu Vi Buritania), 38 years old (30 at the time of her "death"), is a fictional character of the Sunrise anime series, Code Geass: Lelouch of the Rebellion. She is voiced by Asako Dodo, and in the english dub by Kari Wahlgren.

Character Outline
Marianne vi Britannia is the late 98th Empress of the Holy Britannian Empire and the mother of Lelouch and Nunnally. Her commoner status by birth caused her to earn the jealousy of other imperial wives and nobles, which Lelouch suspected had resulted in her murder. Lelouch's investigation revealed, however, that several members of the Imperial House not related to her by blood respected and admired Empress Marianne, such as Clovis, Euphemia, especially Cornelia, who idolized her and put a lot of fruitless effort into investigating the assassination.

It is hinted that her supporters were the Ashford Foundation, which explains why their social statuses were ruined after her death and why they consented to protect Lelouch and Nunnally. She had also piloted one of the earliest Knightmare Frames, the Ganymede, which was developed by the Ashford family and is well known for her superior Knightmare Frame piloting skills, hence the nickname, "Marianne the Flash". She also became a member of the Knights of the Round thanks to these skills. Several times throughout the series, Marianne's consciousness has been shown to be communicating with C.C. as a side effect of her Geass.

At the end of season one, Lelouch, by questioning Cornelia, discovers that Marianne had ordered Cornelia to shut down the security on the day of her attack, implying that she knew about the attack beforehand. It is eventually revealed that the security was lowered by Marianne under the request of V.V. and he was the real culprit, who killed Marianne out of jealousy.

Marianne's spirit is revealed to be within Anya Alstreim's body. She recovers C.C.'s memories and heads to Kamine Island with C.C. to help Lelouch. She is revealed to have had a contract with C.C., though she never fulfilled her end of the bargain by becoming immortal through acquiring the Code. She attempts to aid Charles in triggering Ragnarök, but is killed when Lelouch uses his geass to turn the gods on them both.

Personality
Because of her death, little is known about Marianne as a person; early Code Geass side materials portray Marianne as a sweet, kindhearted woman with a rebellious spirit and a deep protective instinct towards her children. Lelouch gives two examples of this: in one she rode a horse into the palace's great hall and in the other she picked a fight with several of the Emperor's other wives all at once. In a flashback from one of the novels, she uses the Ganymede to intimidate a fellow consort who had been harassing Lelouch and Nunnally — all the while maintaining her friendly disposition. Later side materials reveal her true nature as a selfish, heartless former member of Knights of the Round who helped to overthrow the previous Emperor of Britannia and install Charles as the 98th Emperor. She only superficially loves her children and will not hesitate to kill them if they get in her way.

Marianne's conversations with C.C., one-sided in the anime but scripted out by the staff (and actually revealed in the Nintendo DS game), show that she has a playful side, often teasing C.C. when the immortal girl tries to deny any sort of attachment to Lelouch.

Geass
Marianne's Geass allows her to transfer her spirit (along with her geass) onto another person. A side effect is that, when her consciousness surfaces, she can speak with C.C telepathically. She used it after being mortally injured by V.V. If her body is kept intact, there is a possibility that she can return to it.
