Frozen Sven is a non-speaking reindeer, who has been a companion to Kristoff since they were young. Kristoff understands what Sven communicates through his facial expressions and movements, and he sometimes voices Sven's thoughts. The two of them work together
harvesting ice at the beginning of the film, with Sven pulling the
sled that carries the ice. Following this, they meet several trolls that are disguised as rocks, and a female troll adopts Sven and Kristoff. Years later, the two of them travel together to the kingdom of Arendelle on the coronation day of princess
Elsa. In the forest near Arendelle, they subsequently meet princess Anna, Elsa's estranged sister, who asks them to take her to the North Mountain — Elsa's location after fleeing from the kingdom because of unwillingly placing it under an everlasting winter. On their way, Sven and Kristoff lose their sled after being chased by
wolves, but Sven convinces Kristoff to continue helping Anna nonetheless. Later, they meet Olaf, a talking snowman created by Elsa, who offers to guide them. Sven alongside the others manages to help Anna reach Elsa's newly created ice castle, but after Elsa casts ice magic on her, the group brings Anna back to Arendelle. Soon after they leave Anna in her maids' care, Sven shows his intention to return along with Kristoff to her, and they immediately start heading toward Arendelle once they realize Anna is in danger on account of a
snowstorm that is forming. On the frozen
fjord near Arendelle, Sven then saves Kristoff from falling into the icy water. Because of their actions throughout the story, Sven and the others help overcome
Hans, the evil acting leader of Arendelle, and contribute to Anna's permanent reunion with Elsa and to Elsa being able to bring summer back in the end. As a result, Elsa awards a medal to Sven, and Anna offers him and Kristoff a new sled.
''Olaf's Frozen Adventure'' Sven also appears in the
featurette ''
Olaf's Frozen Adventure'' (2017), at the beginning of which he brings a huge bell to the castle along with Kristoff to celebrate Christmas. He then helps Kristoff to explain a
tradition among trolls to Anna and Elsa. Afterward, Sven and Olaf decide to go in search of family traditions for Anna and Elsa since they do not have any. On their way back to the castle after collecting many traditions, the sled pulled by Sven goes on fire. Following the sled's destruction, Sven and Olaf end up on opposite sides of a ravine. After realizing that Olaf has been approached by wolves, Sven immediately runs back to the kingdom in order to get help. Upon arriving there, he tries to explain to Kristoff what has happened to Olaf, but he manages to understand the situation only after Anna and Elsa correctly interpret Sven's message. They right away begin their search for Olaf, and when they find him covered with snow, Sven catches him by his nose and pulls him out. While heading back toward the castle, Sven stops alongside everyone else at a frozen lake, where Elsa creates a
Christmas tree out of ice. Afterward, she places Olaf between Sven's antlers, and all of them look joyfully at the tree.

Among the Northuldra, Sven encounters other reindeer. After Anna leaves with Elsa and Olaf to find the voice, Sven accompanies Kristoff when he sings about Anna.
