So Hans was this lovely guy during the movie and suddenly he is just evil. Supposedly his plan was to charm the kingdom into letting him be the ruler, but all his nice scenes were basically him faking everything.
Betraying Anna
She explained to Hans that Elsa froze her heart and only an act of true love could save her from the curse. However, just as the two were about to kiss, Hans revealed that he never truly loved Anna and was using her as a tool to usurp Arendelle.
Like many villains, Hans is arrogant and power-hungry, visiting Arendelle in order to rule the kingdom by any means, revealing that his only desire is to become king, prepared to rid anyone necessary in any way he can for his quest for power, making him amongst Disney's more complex villains.
Although he is portrayed as honest and noble throughout most of the film, he is later revealed to be deceptive, calculating, and cruel. Hans' villainy is a plot twist in Frozen, revealed in the film's final act.
Hans knew that as the heir, Elsa was the preferable bride, as his marriage to her would ensure his swift ascension to the throne. But when the prince heard that Elsa kept her distance from others, he realized that he would have to change tactics and had no qualms whatsoever in planning for the queen's death.
But what he didn't realize was that he and Anna really were an excellent match and that he was deeply in love with her! Now, Hans is a sensible man who knows exactly what he wants. He won't let this romance get in the way of his grand coup.
Disney Pixar
Elsa's boyfriend Jack Frost is from another studio.
Frozen's Elsa is a rare Disney protagonist who has powerful magic herself. Elsa's powers give her control over ice and snow. This turns out to have a huge range of abilities. Elsa is able to conjure ice and throw it at her enemies.
Anna and Hans would most likely, have kids of their own in order to keep the Arendelle Royal Family in the castle. There are rumors that, Anna would move to Corona to continue her education (mainly in agriculture or veterinary study) and stay with her relative Rapunzel.
Prince Hans' main motive is to become King of Arendelle. To do that, two things must happen first: He has to marry Princess Anna ('As heir, Elsa was preferable, of course, but no one was getting anywhere with her. ' So he turned to Anna).
There is a elephant in the room named Prince Hans. He was revealed to be a secret villain at the end of the film. His plan was to marry Anna, kill both sisters, and gain power to the throne due to being thirteenth in line in his family not being able to gain the throne in his own kingdom.
Hans spontaneously proposes to Anna and she happily accepts. Anna asks for Elsa's blessing to marry Hans, but she refuses and criticizes her for agreeing to marry someone she has just met.
When Anna first met Hans, she became infatuated with his good looks and charm. As the two became more acquainted with each other and their lonely pasts, they soon shared a romantic duet which ended with Hans proposing to Anna, which she gladly accepted despite having only known him for a day.
Hans is first seen arriving in Arendelle on his horse Sitron, accidentally running into Princess Anna. Using grace and charm, Hans immediately woos the lovesick princess making her his back-up plan, with Anna almost immediately falling for him due to his wondrous looks and undeniable charisma.
Being married to Anna would not give him a claim to the throne. Instead the next in line after Anna would be any brothers or sisters of Anna and Elsas dad, and it would keep going up. If he had none it would then go to the descendants any brothers and sisters of Elsa and Annas grandfather etc.
Elsa Has Magic Powers
Elsa has magic ice powers which automatically makes her cooler than Anna on so many levels. She created an entire ice castle for herself because she wanted to, and there is no fan in the world who could say they wouldn't want this ability.
Despite her daughter Elsa having magic ice powers, Queen Iduna does not appear to wield any sort of magical abilities, making her a normal human being.
We Got This Covered reported, “Disney has plans to give Elsa a female love interest” in Frozen 3. The site reports, “We're told it's definitely happening and again, the intention is for Elsa to have a girlfriend in the prequel, confirming her sexuality in the process.”
Elysium is the first daughter of Elsa and Jack Frost, protagonists in Frozen and Rise of the Guardians. She is also a Princess of Arendelle and Junior Guardian of Winter. She is the older sister to Elise and is the first heir to the Throne of Arendelle.
To this, another child replied, "So does everyone else's." According to Jennifer Lee, Anna is 18 years old in the film, while both Elsa and Kristoff are 21 years old and Hans is 23 years old.
When Anna first met Hans, she was immediately taken by his good looks and charm; after Hans revealed that he had a difficult past due to his twelve older brothers, Anna felt that she could relate and agreed to marry the prince, even though she had known him for less than a day.
