Hans is the main antagonist in the musical adapation of Frozen, based on the character of the same name.
Background[]
John Riddle originated the role of Hans in the Frozen musical. His role is essentially the same, serving as the antagonist with a goal to marry Anna and take over Arendelle as king. The motivation for some of his actions were made clear in the stage show, while they were only implied in the film. For example, when asked why he continuously defends Elsa, Hans declares that it is because of his relationship with Anna.
Hans is given a solo song with two reprises, "Hans of the Southern Isles", which explains some of his background. He first performs the song when he meets Anna, using it to gain her trust by proclaiming he is someone "even more embarrassing to be" than the insecure princess. The first reprise happens after Hans has been left in charge of Arendelle; he uses the song to gain the townsfolk's trust, and claims that he and Anna will lead them back to summer should Elsa turn out to truly be a monster. The final reprise is briefly performed when Hans betrays Anna.
In the moments leading into "Love is an Open Door", Hans claims that he wants to start a family. During the song itself, he and Anna share a legitimate kiss, something that doesn't occur at any point during the film.
