Rajari was a Romulan smuggler and criminal in the late 24th century. Physically, he appeared similar to Vulcans, but his emotional displays revealed his true species. By nature, Rajari was a sadist, believing in the inherent superiority of all males and that women were meant to be subject to men's whims. Like other Romulans, Rajari was taught about his people's genetic relatives; the Vulcans, and the fact they were "insufferably boring". Rajari believed a monster existed in the hearts of every Vulcan, despite centuries of trying to bury it, and they'd be much better off letting it loose.
