R'Klll was a Skrull empress who came from the House of T'Ryss. She was the eldest daughter of the previous emperor who was murdered by Dorrek VII and reluctantly married him. R'Klll was planning to kill Dorrek VII, and he in turn was planning the same for her. During the Skrull war with Xandar, the fighting got close to Dorrek's flagship and he ordered them to take him to where it was safe, the throneworld. Disgusted at his cowardice, she assassinated the emperor by shooting him in the back. Taking control of the empire, she ordered a discrete withdrawal from Xandar and ended the war.
