C.C.

C.C. was the leader of the Geass Order before disappearing of Marianne and the leader of the Order of the Black Knights until she returned Lelouch's memories. Though, it appears she notes these qualities to be essential to her sense of self, saying "That is what makes me C.C." in reference to them. She's shown to be pragmatic, focused on fulfilling her "contract" with Lelouch, which also serves to show her selfish side. Early on, she was willing to shoot Lelouch to hold him back from meeting Cornelia's challenge to him. In the second season, she suggested that Lelouch use Geass on Nunnally to bring her over to his side. She's also shown to be isolated, preferring to act alone to solve personal matters and being quite snarky and dismissive towards most people. C.C. can also be very secretive, to the point of being on par with Lelouch, albeit much less coordinated than the latter. C.C. is immortal, healing from any kind of wound (implied to include beheading) with enough time. She also doesn't age. Apart from her immortality, C.C. has the ability to bestow people with the power of Geass, which manifests differently in each person but generally carries the ability to affect the minds of those it is used on in some way.
