Hans

Prince Hans Westerguard of the Southern Isles is the main antagonist of Frozen. Hans is a prince from the Southern Isles, a neighboring kingdom of Arendelle. Not much is known about the prince's past, but he is the youngest of thirteen royal siblings, and was neglected because of this.

Knowing he would not live to rule the throne of the Southern Isles, Hans concocted a scheme to marry into monarchy. And when Arendelle is set to have a coronation, he jumps at the opportunity.

However, since the queen to-be is far too collected to woo, he instead goes for her younger sister,  Anna, planning to murder Queen Elsa after their marriage, thus becoming king (with Anna as his consort).
