Alice

Alice is a tomboyish girl who is Nunnally's best friend and classmate, but is secretly an agent of the Irregulars assigned to the surveillance of Milly Ashford under the cover identity of a middle school student. Alice's normal physical abilities have been augmented with cells originating from C.C., giving her a Geass ability called "The Speed," which allows her to hyperaccelerate all objects within a given radius by manipulating gravitational pull. Designated by her unit to pilot a Knightmare Frame customized to exploit this ability, Alice serves as a highly effective point man on the field of battle. When her ability is active, a Geass sigil appears on her forehead. Alice's blood contains a chemical suppressant that minimizes the activity of C.C.'s biological matter, which has a tendency to strain and overtax the human body. A neutralizer for the suppressant may be administered to temporarily boost the effect of "The Speed" in battle, enabling movement of sufficiently high speed that it resembles teleportation. Alice's relationship with Nunnally in the spin-off is comparable to that between Suzaku and Lelouch in the anime.
