Elena Petrova

Elena Petrova was originally thought to be a neutral scientist assisting Doctor Ignatio Moebius. She was "captured" by prominent Nod officer Gideon Raveshaw, along with Mobius and his daughter Sydney Mobius. However, she was really a turncoat, and helping Nod in their Project Regenesis. She helped them create all kinds of genetic mutants through Tiberium. She made many, from the primitive initiate, barely able to use weapons, to the acolyte, the man soldier, to the fearsome Templar. However, she also turned Raveshaw into a totally subservient mutant- that GDI commando Captain Nick "Havoc" Parker killed. Eventually, he also battled her. Even though she had the assistance of initiates and visceroids, he killed her and rescued Moebius and his daughter.
