Ciel (シエル, Shieru?) is a supporting main character in the Mega Man Zero series of action platformer games.
Mega Man ZeroEdit
Ciel is a human and former Reploid researcher that worked for Neo Arcadia. When Mega Man X disappeared eight years before the events of Mega Man Zero begins, Ciel created Copy X to replace him. Amazingly, Ciel is supposed to be aged 14 during Mega Man Zero, which means she built Copy-X at the age of 6, making her a child prodigy. She is one of the genetically altered children born from Neo Arcadia experiments with DNA, which is what allowed her to attain such a high level of knowledge at such a young age. Additionally, one of her ancestors, another female scientist, was apparently directly responsible for the creation of the original Mother Elf, from which all other Cyber-elves were spawned.
When the Neo Arcadian government began oppressing and executing Reploids to solve their energy crisis, Ciel migrated with Reploid refugees to a ruined city when she was 9 years old. Knowing they were being falsely accused, she felt guilt and decided she could not stand by helplessly, and she soon became somewhat of a mother figure to many of the Reploid refugees, particularly a young girl she named Alouette. Times grew more desperate, though, and she eventually found her only hope to be uncovering a legendary hero that most people didn't even believe in anymore: the legendary Maverick Hunter Zero. She sought and eventually found him, though it took the sacrifice of one of her Cyber-elves, Passy, to wake him up.
Mega Man ZXEdit
In Mega Man ZX, it is revealed through recovered Data Disks that Ciel went missing shortly after she discovered Model W and created the six Biometals in response. Ciel is also revealed as the 'Sis' of Prairie, the commander of the Guardians, though they are not biological sisters. It is strongly hinted that Prairie is actually Alouette, due to this relationship with Ciel being identical to Aloutte's, as well as general similarities between Prairie and Alouette's character designs. In particular, they carry the same stuffed animal. In ZX, images of Prairie's predecessor depicted in Guardian reports also resemble Ciel, even though her image is always covered in shadows.
Other Appearance Edit
When the player makes Zero taunt in SNK vs. Capcom: SVC Chaos, Ciel pops up onscreen in a quick cameo.
