C.C. Appearances in Other Media

Code Geass: The Manga
C.C. is present in the manga with only a few differences in her appearances. She was discovered in a plane crash and she appeared before Lelouch creates a plan to save Suzaku.

Suzaku of the Counterattack
Despite the plot differences, C.C.'s role is nearly identical to that of the anime. She is freed by Lelouch and Suzaku and gives Lelouch his Geass. Lelouch then takes C.C. back with him to Ashford Academy. Due to being grievously wounded shortly after freeing her, Suzaku does not recognize C.C.

Renya of Darkness
Set in the Edo period, C.C. appeared in an armor that was said to resemble that of Portuguese Jesuits and witnessed the attack led by Isshin Sumeragi on Renya's village. She later appeared before an injured Renya when he saw his friends being captured and threw his Shuriken at her. C.C. remained alive, however, which shocked Renya. She offered him a contract in exchange for the power to save his friends, which Renya accepted, and C.C. started the process. In the middle of it all, C.C. was surprised by a spark that appeared to be hurting Renya and by the appearance of an unknown long-haired figure bearing a resemblance to Lelouch. After that she asked Renya his name and revealed that he had somehow "failed".
