Sydney Mobius

Sydney Moebius was the daughter of Ignatio Moebius, the leading Tiberium researcher affiliated with GDI. She was highly intelligent and enjoyed intellectual pursuits, gaining a doctorate before ever reaching the age of thirty. Additionally, she was highly adept at computer sciences.

When the Tiberium meteorite hit, she researched the new mineral along with her father. Unlike him, she was more interested in using it as a weapon. She co-designed the Mobius Suit for safer research and later upgraded it.

In the closing stages of the war, she, along with her father and doctor elena Petrova, was captured by Nod, who forced them to work on the human augmentation project, called project ReGenesis, to create a new breed of humans, advanced with Tiberium. She and her father were shuffled between various Nod facilities before being rescued from a Black Hand research facility in a chateau occupied by Nod forces. She was unfortunately separated from her father and, escorted by captain Nick Parker, managed to reach safety, narrowly escaping a nuclear warhead. She later volunteered to general Adam Locke to help captain Parker locate her father. The general, contrary to captain's objections, allowed the young doctor to accompany him in the Mobius suit. Soon after deployment, both were apprehended by Black Hand chameleons and placed in custody. While captain Parker managed to escape imprisonment, he was unable to rescue doctor Moebius, who was already sent on her way to the Cairo Temple of Nod to be subject to the final version of the ReGenesis augmentation procedure, to become truly "divine", as referred to the process by Kane. While being subjected to the procedure, captain Parker intervened and upon killing doctor Petrova who defected to the Brotherhood rescued her and escorted the doctor through the Temple. On the way, the doctor prevented the Temple's nuclear missile from launching by rewiring the blast door conduits and missile holding clamps, making it detonate withing the Temple. Afterwards, she was reunited with her father and continued research for GDI until her death.
