Viserys Targaryen

Exiled prince of a fallen dynasty, Viserys wants only his throne back, and he'll trade anything to get it — including his sister Daenerys, married off to a Dothraki warlord for the promise of an army. He postures as a king, prone to cruelty and self-pity, clinging to a birthright nobody in Essos cares about.

Harry Lloyd plays entitlement as a wound: every sneer masks how brittle Viserys actually is, a man raised on stories of greatness who has never held real power. He's the show's early lesson that blood and birthright mean nothing without strength to back them — a petty tyrant undone by the very people he thinks beneath him.
