Doctor Ciel

Doctor Ciel is a supporting protagonist and the main heroine of the Mega Man Zero series. A human scientist, Ciel sought out the legendary Reploid hero, Zero, to fight back against the tyranny of Neo Arcadia. Ciel leads the Resistance to support Zero. Ciel is a young girl who is 1 years old with a modest stature. She has pale skin, cobalt blue eyes, long thick blonde hair with three angular bangs, usually tied into a ponytail. She wears a pink outfit consisting of a helmet, a sleeveless dress, a resistance vest, plated high heels and white gloves, with a black bodysuit underneath. The helmet has a hole on the back for the ponytail, and a retractable white visor. She also has winter clothing composed of a long pink jacket and thick boots. Ciel is a gentle, kindhearted person who is always concerned about the welfare of others. She has an issue with insecurities as a result of Neo Arcadia's pressure on the Resistance, but Zero's continued support gives her the motivation to move forward. She cares greatly about Zero and often regrets requesting his help for dangerous missions. She is also close to Alouette, having named the girl and given her the stuffed animal she is always carrying.

Despite her age, Ciel is a genius scientist, already capable of creating a replica of X merely by observing the methods used to create the Four Guardians. Her study of Cyber-elves also allows her to develop a new energy source in the Ciel System, an important discovery that starts a new age in the field of energy research. Ciel believes in solving problems not through fighting, but through the power of science; she can be very dedicated to her research, to the point of staying up late. Ciel also has an emphatic connection with Cyber-elves, and illustrations often depict her alongside them in order to reflect this. this is an alternative universe cause copy zero is nowhere near to be found unlike the original timeline! they are struggling against copy x's forces! According to the Mega Man Zero Official Complete Works, Ciel is a product of Neo Arcadia's technological advancements, which is what allowed her to attain such a high level of knowledge at such a young age. With the goal of creating a utopia for humans and Reploids, Neo Arcadian researchers began to produce humans with altered DNA. Some of these humans were children born specifically to develop better Reploids to assist in the research. Ciel was one of these children, and stood out as a prodigy, being able to learn just by watching and mimicking experiments. Ciel became a Reploid researcher that worked for Neo Arcadia. When Mega Man X disappeared some years before the events of Mega Man Zero begins, Ciel created Copy X to replace him when she was young.[1][2][3] 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.

However, when Copy X began oppressing and executing Reploids to solve Neo Arcadia's energy crisis, Ciel felt very guilty that her own creation was behind it, so she migrated with Reploid refugees to a ruined city. Knowing they were being falsely accused, Ciel decided she could not stand by helplessly, so she formed the Resistance, acting to free Reploids from Copy X's regime. The Resistance (レジスタンス Rejisutansu) is a group of Reploids from the Mega Man Zero series that were labeled as Mavericks by Neo Arcadia. The leader of the Resistance is Ciel. Although they oppose Neo Arcadia and its government, they mean no harm to anyone, and fight only to defend themselves and, by the time of the fourth game, all those facing oppression from Dr. Weil. In fact, Ciel seeks to end this fighting through more peaceful means. With the exception of Ciel, the Resistance is entirely composed of Reploids. The majority wears a green soldier uniform consisting of a beret with a red triangle, a sleeveless vest, pants and brown metallic boots. Female variants have skirts instead of pants. The Resistance members are typically armed with old Buster Shot models.

Although they are an organized group, most Resistance members are in fact civilians who joined to avoid execution by Neo Arcadia. Therefore, they lack the specs to fight the Neo Arcadian army and have to resort to guerrilla tactics to survive. They hope that their work will allow Ciel to complete her research on a new energy source, which will solve the energy crisis that led Neo Arcadia to terminate Reploids in the first place. However, this is a difficult effort due to the Resistance's limited resources, a problem compounded by their need to steal supplies from Neo Arcadia.
