Nora is a female enemy in dominatrix suit who fights with a whip. She works for questionable members-only clubs, where everyone calls her "Queen". Encountered fairly regularly, she can knock you down with her whip. Once you knock her down she won't get up until you move away or after quite a bit of time. Be prepared for a whip attack once she does get up.
Streets of Rage 2
Though Nora herself doesn't appear in the game, a version of Electra with her name functions as an enemy of stage 3, accompanied by L.Lisa.
Streets of Rage 4
She returns as the boss of Stage 3. She is constantly aided by Galsias, whom she can whip to power them up, granting them more health and super armor, switching their names to Galsiaaaaa and changing their hair to shining yellow as a result. Occasionally her whip can heal or even revive them. After her defeat, she goes into a breakdown to crash the ship into the pier.
In Stage 11, 3 palette swaps of her simultaneously appear before facing the boss: 2 of them with lower health (Belle and Queen) and 1 of them (Stiletto) acts as a mini-boss. During this fight, no Galsias will appear, meaning you won't fight any powered-up Galsias like in Stage 3. Stiletto has additional armor properties when attempting to use the whip.
