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.

Marianne Vi Britannia is the late empress of the Britannia Empire and the mother of Lelouch and Nunnally. Despite her rank as a Knight of Honor, Marianne's commoner status by birth caused her to earn the jealousy of other imperial wives and nobles, which Lelouch suspects had resulted in her murder. Under the influence of Lelouch's Geass, Cornelia notes that Marianne had ordered her personal guard to leave on the day of her attack, implying that she knew it was going to happen. Her assassination also resulted in the disgrace of the Ashford Foundation, another suspected motive. However, several members of the Imperial House not related to her by blood are shown to have respected and admired her, including Clovis, Euphemia, Jeremiah (his first posting was as one of her bodyguards), and in particular Cornelia, who commanded Marianne's personal guard and put much 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". In episode 23, it is revealed that C.C has apparently been talking to Marianne herself, via an unknown method. In episode 7 of R2, C.C. was talking with Marianne again.

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.

She is known to 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 and 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. Curiously, C.C. seems to be able to speak with Marianne herself via an unknown method, though the viewer only hears C.C.'s side of the conversation. The full conversation is scripted out by the staff, and revealed in the Nintendo DS game. Marianne seems to enjoy teasing C.C. when the immortal girl tries to deny any sort of attachment to Lelouch.
