Hans is Anna's false lover. When Anna goes off to find Elsa, she leaves Hans in charge. Anna's horse runs back to Arendelle, and this leads Hans to round up some volunteers to come with him to the North Mountains to rescue Anna. After a fierce battle with Elsa's colossal bodyguard, Marshmallow, Hans succeeds in capturing Elsa. In the castle dungeon, he convinces Elsa to stop the winter, but she tells him she can't. However, when Anna's heart is frozen and she is brought to Hans to receive a kiss from him, just before the kiss he pulls back, chuckles, and says "If only there was someone who loved you." He then reveals his true motives: Hans wooed Anna for the purpose of marrying into a royal family and becoming king, because he has no chance of inheriting the throne of the Southern Isles as thirteenth in line. Instead of saving Anna's life, he deliberately leaves her to die. Hans sentences Elsa with a death charge, but Elsa's powers become strong enough for her to break out of the castle dungeon and escape. Later, when the two sisters are outside in an uncontrollable blizzard caused by Elsa, Hans confronts the queen. She asks him to take care of Anna, and Hans goes as far as to lie to her that Anna was killed by her magic. While Elsa is busy grieving her sister's death, Hans prepares to finish her by striking her with his sword when Anna leaps in front of Hans just before freezing solid to save Elsa. The recoil from hitting the frozen Anna was enough to shatter the sword and knock Hans unconscious. Anna's sacrifice also allowed Elsa to realize that it was love that could reverse her devastating ice powers and revive Anna. Hans awakens to find that the eternal winter has ended, and is shocked when he sees Anna alive and well, since he thought her heart had been frozen. Anna walks over to Hans, and, telling him that the only frozen heart was his, feeds him a knuckle sandwich and knocks him off the boat they're standing on. Afterwards, he is put in the brig on a ship and sent back to his own kingdom to face his brothers for his behavior in Arendelle.
