Dalque

Dalque is a dark-skinned girl who serves as point man for the Irregulars. She possesses a Geass ability known as "The Power," which augments her physical strength by exaggerating the magnitude of macroscopic forces. When her ability is active, a Geass sigil appears upon her forehead. Her Knightmare Frame cockpit is installed with synchronization receptors that allow expression of this ability as a highly effective frame strength enhancer. Source: CodeGeass Wiki
