King Westergaard

King Westergaard is the overarching antagonist of the 2015 novel A Frozen Heart based on the 2013 Disney film Frozen. He is the tyrannical ruler of the Southern Isles and the abusive father of Prince Hans.

History
As the ruler of the Southern Isles, King Westergaard was known to be a despicable ruler due to his treating his subjects (including his own royal family) like trash, nothing more than to expand and secure his power of his country. To that end, he has extorted heavy taxes and executed those who resist his laws or criticize him in person.

Being the father of 13 princes, King Westergaard molded his sons to become as greedy and ruthless as himself through torture and abuse; even forcibly having them to collect from delinquent taxpayers. He was also indifferent to wife Queen Westergaard as he completely ignores her and treats her as a trophy queen, and she would drown her sorrows by drinking wine while being forced to watch her husband torment their sons. Because of this treatment, most of the princes became so self-obsessed and started tormenting each other. The youngest of the princes (Hans) was considered the black sheep as Hans was unwilling at that time to share King Westergaard's views of Social Darwinism, and as such, King Westergaard orders all his older sons to torment Hans for their own amusement in hopes of toughening him up.

The older princes (under King Westergaard's watch) played pranks on Hans during their childhood, even mocking him for being their mother's favorite during her birthday party, with the exception of the third oldest prince Lars, who is exceptionally kind to Hans. It is also revealed that King Westergaard also forced his sons into arranged marriages in hopes that he would produce new heirs for the kingdom, and that many of the princes' wives are miserable; even Lars and his wife Helga feel that they are unhappy with the relationship that King Westergaard forced them into.

Because of King Westergaard's treatment, Hans vows to move out from the Southern Isles and find another kingdom so that he can become a better ruler than his father himself. He senses an opportunity when Princess Elsa is about to be crown Queen of Arendelle. Upon hearing of the imminent event, King Westergaard reluctantly allows Hans to attend the event, on the condition that he return back so that he can watch over his brothers' children.

Formulating a plan for power due to the trauma inflicted by King Westergaard, Hans tries to get himself into marrying either Elsa or her sister Anna so that he could kill them and secure his new power as the new King of Arendelle. However, he is foiled and ends up being sent back on a ship to the Southern Isles for punishment. It can be implied that King Westergaard has subjected Hans a severe punishment for his actions.

Trivia

 * King Westergaard can be considered the Greater-Scope Villain of the 2013 film as his treatment towards Hans is what shaped the latter into becoming the villain of the film. What's even more upsetting is that King Westergaard got away with his actions towards Hans.
