While it's insinuated that Prince Hans (Santino Fontana), the main antagonist and former love interest of Anna (Kristen Bell), will face the consequences for his actions against Elsa (Idina Menzel) and Anna at the end of Frozen, Hans’ fate is never addressed within the sequel Frozen 2. So what exactly happened to the power-hungry Prince Hans after the events of Frozen? The Disney short film Frozen Fever explains that Hans is currently paying for his crimes against Arendelle within his home country, The Southern Isles.
In Frozen, Prince Hans is introduced as the handsome prince who proposes to Anna not long after meeting her at Elsa’s coronation ball. While he first appears to love Anna, it’s revealed later that Hans is plotting to marry Anna in order to become King of Arendelle. After Elsa accidentally freezes Anna’s heart with her elemental powers, Hans convinces the dignitaries from the other neighboring kingdoms that Anna died and married him beforehand, making him the new leader of Arendelle. After Anna saves Elsa from being killed by Hans at the end of Frozen and his plot to take over the throne is exposed, Hans is imprisoned on a French ship heading for the Southern Isles and is never seen again until the short Frozen Fever, which follows Elsa as she attempts to throw Anna a birthday party despite having a cold.
In Frozen Fever, Hans is briefly seen towards the end of the short film shoveling horse manure in the Southern Isles. When Elsa insists that she blow the birthday bugle horn in honor of Anna’s birthday, Elsa accidentally creates a giant snowball with her ice magic, which flies out of the horn and across the ocean towards the Southern Isles. Landing directly onto Prince Hans, the snowball hilariously throws him into a wheelbarrow full of horse manure. While Hans appears to still be wearing his royal garb, the fact that he’s cleaning up after the horses suggests that he may have been stripped of his royal status after the events of Frozen. Alternatively, this scene could also be depicting how Hans is treated as an underling in his own family, which is detailed within the non-canon Frozen spin-off novel A Frozen Heart.
When Elsa's snowball hits Hans, his legs are seen dangling out from underneath the pile of snow and manure, and he isn’t shown to be moving before the frame cuts back to Anna, who puts her feverish sister to bed. While Hans made a brief cameo in Frozen 2 as a memory preserved in Ahtohallan, he is never physically seen within the Frozen franchise after this scene in Frozen Fever, which suggests Elsa’s snowball may have accidentally killed him. While having Hans drown in manure wouldn’t be the most gruesome Disney villain death featured on screen, it would certainly be the most fitting death for a villain such as Hans. As someone who craved power so much that he was willing to kill the two living successors to claim Arendelle's throne, it would be pretty ironic if he were to die doing something as subservient as shoveling an animal’s feces.
While the creation of the snowball first appears to be an accident in Frozen Fever, the scene suggests that Elsa may have intended to hit Hans with the snowball. Unlike when Elsa created the Snowgies every time she sneezed, the snowball is the first bit of elemental magic that Elsa creates under her high fever that is both insentient and begins with an intentional action: to blow the horn in honor of her sister’s birthday. Throughout Frozen Fever, Elsa is determined to give Anna the perfect birthday since she missed out on celebrations in the past due to Elsa’s magic. Since Elsa has been channeling all of her energy into fostering her sister's happiness in her fevered state, it's possible Elsa created the snowball with the unconscious purpose of throwing it at Hans, which is why it was insentient to begin with.
While it’s unclear whether or not Hans was killed by the snowball within Frozen Fever, his fate within the Frozen franchise could still be addressed in the currently unconfirmed sequel Frozen 3.
