Mileena (Mortal Kombat 1)

Born mere seconds ahead of her twin sister, Mileena is the rightful heir to Outworld's throne. But even so, there are those who distrust Mileena's impulsiveness. They whisper that Kitana, with her steadier hand, should replace Mileena as Sindel's heir. As Mileena fights for legitimacy, she hides a horrible secret: she is infected with the dreaded and lethal Tarkat disease. Were her affliction found out, Mileena would be forced into battle to save her throne.
