Darklord’s Gals: Dark Lord Gaol (魔王ガイナス Maou Gainasu, lit. “Demon King Gainas”) is a brand new antagonist introduced in Kid Icarus: Uprising. She appears to be a dark, knight-like character that speaks in an evil and distorted voice that makes her seem masculine. She serves as the boss of Magnus and the Dark Lord.
It is shown that she lives in a dreary castle, and that she serves as another rival towards Palutena, as well as Magnus who has apparently had past encounters with her. In the trailer from E3 2011, Gaol doesn’t appear intimidated by Pit at all, referring to him as “Palutena’s little messenger boy.”
A general of the Underworld Army who leads thousands of infernal troops on a violent crusade against the surface world. Gaol’s armor emits cursed magical energy that gives the dark lord the ability to float in midair and fire magic missiles.
Brave Gaol had once been a spy for the surface world, tasked with assessing the strength of the Underworld Army. Sadly, she was captured and forced to don the cursed armor of a dark lord, making her little more than a slave to evil. via Wikia
