Marianne vi Britannia

Marianne Vi Britannia (マリアンヌ・ヴィ・ブリタニア, Mariannu Vi Buritania) is a fictional character of the Sunrise anime series, Code Geass: Lelouch of the Rebellion.

Character Outline
Marianne Vi Britannia is the late empress of the Britannia 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 suspects 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". 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 was the real culprit, who killed Marianne out of jealousy.

when first introduced, she was shown to apparently shield Nunnally during the attack that took her life, however, Nunally's legs were disabled and she lost her sight. It is also to be noted that her death greatly affected and changes the life of Lelouch, who went on a great length to avenge her death and formed the resolution to create a new world where Nunnally can live in peace. It has been assumed by some that Marianne lowered the security, made herself vulnerable.

Because of her death, little is known about Marianne as a person; the side materials paint her as a sweet, kind-hearted woman, albeit one with a rebellious spirit and a deep protective instinct towards her children. Lelouch himself alludes to two such instances, one where she rode a horse into the palace's great hall, and another where 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 cruelly harassing Lelouch and Nunnally - all while maintaining a cheery, motherly disposition with a warm smile on her face. 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.

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 to turn the gods on them both.

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 mortally injured by V.V. If her body are kept, she can return to the living world
