- “Don't worry about me.”
- ―Kristoff to Anna
Kristoff Bjorgman was an ice harvester who, alongside his reindeer friend, Sven, was raised by the trolls. He generally kept to himself and only interacted with other humans when necessary, preferring the company of Sven. As such, Kristoff only accompanied Anna on her quest to retrieve Elsa strictly as a business arrangement but would eventually develop feelings for the princess; to this end, he strove to ensure her safety as she worked to restore both summer and her bond with her estranged sister. After summer's return, Kristoff and Anna began a romantic relationship.
In the early years of his life, Kristoff mostly accompanied the ice harvesters, working hard in spite of his age to earn his place amongst the grown men. One night when he was eight, Kristoff was following the other ice harvesters back to Arendelle on a small sled pulled by Sven. However, he noticed two horses rush past and was surprised when he saw that there was a trail of ice being left behind. Curious, Kristoff abandoned his sled and mounted Sven in the hopes of seeing where the trail of ice led; the two soon reached the Valley of the Living Rock.
Not wanting to be seen by the riders, Kristoff and Sven hid behind a series of rocks. As Kristoff watched the four figures, he was shocked to see some rocks move of their own accord towards the visitors, though he eventually realized that the rocks were in fact, trolls. To his surprise, the rock he and Sven had been hiding behind suddenly sprung to life; this female troll, Bulda, regarded Kristoff and Sven warmly, remarking that she would "keep" them. Then, the trio watched as Pabbie healed a little girl with his magic.
True to her word, Bulda took in Kristoff and Sven, and Kristoff came to regard the trolls as his adopted family. In this time, Kristoff grew very close to Sven, going as far as simulating Sven's voice so that they could converse.
Thirteen years later, Kristoff had grown into a self-sufficient ice harvester. He and Sven were present in the village outside of the castle on the day of Elsa's coronation, and they watched the various guests arrive in Arendelle for the momentous occasion. However, Kristoff did not stay to witness Elsa's coronation and as such, was not present for the revelation of her ice powers. Sometime after Elsa cast her winter spell, Kristoff was at the North Mountain, where he encountered a magical weather disturbance generated by the queen during her flight. Due the sudden onset of winter weather conditions in summer, Kristoff headed to Wandering Oaken's Trading Post and Sauna to purchase extra equipment.
At night, Kristoff arrived at Oaken's trading post and burst through the door, covered head-to-toe in snow; inside, Oaken greeted him while a young woman, Anna, glanced at his snow-covered appearance with bewilderment. Not interested in making conversation, Kristoff walked right up to Anna, surprising her with his sudden approach, and brusquely asked for her to stand aside so he could grab some carrots. After throwing the carrots onto the counter, Kristoff made for the under-stocked winter department, picking out a pickax and rope while Oaken tried to make friendly conversation, asking about the origin of the stormy weather. As Kristoff replied that the storm was coming from the North Mountain, he brought over the pickax and rope but was dismayed when he found out Oaken was charging four times the amount he had. He pleaded with Oaken, but the trader would not relent, citing "supply and demand" problems, prompting Kristoff to interject that ice harvesting was unprofitable with the current weather.
When Anna heard Kristoff mention the source of the weather, her interest was piqued and she inquired about the nature of the storm, wanting to know if it seemed "magical". However, still irritated at Oaken, Kristoff bluntly told her "yes" and proceeded to insult the store-owner, calling him a "crook". His cheerful disposition evaporating, Oaken became visibly riled, stood up to his full height of seven feet, and violently threw Kristoff face-first into the snow outside. Kristoff regarded Sven with disappointment, stating he was not able to purchase carrots, but brightly pointed out that he knew where they could stay for the night: a small barn located within the vicinity of Oaken's trading post.
Within the barn, Kristoff sang a lullaby to Sven while the two prepared themselves to rest for the night. However, they were interrupted by Anna, who asked Kristoff to guide her to the North Mountain. But Kristoff was uninterested, stating he did not "take people places". At this, Anna threw a sack at Kristoff and with a grunt, he sat upright and looked inside, finding the pickax and rope he was unable to purchase. Realizing Anna was setting up a business arrangement, Kristoff stated that they would leave in the morning and added that she had neglected to purchase Sven's carrots. But Kristoff was surprised when Anna threw carrots at his face; with all the authority she could muster, Anna then proclaimed they were to depart immediately. Unsure what to make of Anna, Kristoff offered Sven a carrot while contemplating his decision.
Kristoff decided to follow Anna's orders and the trio departed for the North Mountain using Kristoff's sled. Hoping to strike up a conversation, Kristoff inquired Anna about what had prompted Elsa to go "all ice-crazy". Admitting fault, Anna explained that Elsa had refused to bless her marriage to man she had just met and though she tried to go into more detail, Kristoff was remained fixated on the fact Anna had tried to marry a complete stranger. Kristoff openly questioned Anna's judgment and started to expose gaps in the princess's knowledge of Hans; however, Anna adamantly stated her relationship with Hans was "true love", though Kristoff continued to express his doubts. The two continued to bicker, but Kristoff motioned for Anna to stop talking when Sven suddenly stopped, alarmed about something.
Kristoff gazed into the darkness to see what was distressing his friend and saw the eyes of many wolves. Realizing the danger, Kristoff told Sven to run while he lit a torch to defend the sled from the predators. As Kristoff was battling the wolves, Anna intervened, swinging the ice harvester's lute to bring down a wolf; surprised, but impressed with Anna, Kristoff did not notice another wolf approaching and was pulled from the sled, barely managing to hang on to a piece of rope. Helplessly dragged along by the sled, Kristoff was attacked by more wolves; reacting quickly, Anna set a bundle ablaze, threw it at the wolves, and helped Kristoff back onto the sled. Though Anna had saved him, Kristoff was annoyed that he had nearly been set on fire, but he had little time to dwell on it, as he realized Sven was approaching a massive gorge.
Thinking fast, Kristoff threw Anna onto Sven's back and used a knife to sever the ropes binding the reindeer to the sled. Though Anna and Sven managed to clear the gap, Kristoff was trapped on his sled, and without Sven pulling, it was slowly losing momentum. Kristoff was forced to launch himself from the sled in midair, landing precariously on the other side. As Kristoff glanced sadly at the burning wreckage of his vehicle, he began to lose his grip. But before Kristoff slipped down the cliff-side, Anna threw down a pickax tied to rope; with Sven's help, she pulled the ice harvester to safety.
Disappointed over the loss of his sled, Kristoff laid in the snow and covered his face despairingly. Feeling guilty, Anna assured Kristoff she would reimburse him for his losses and stated that she understood if he no longer wished to accompany her. As Anna started to walk off, Kristoff struggled with how to continue; however, with Sven acting as his conscience, Kristoff realized that Anna would perish without his expertise and that her death meant he would receive no compensation. In the end, Kristoff grudgingly decided to assist Anna for the remainder of her journey.
Traveling by foot
The trio continued their journey on foot through the night. By the next day, they had reached a vantage point from which Arendelle was visible and both Kristoff and Anna looked at the frozen landscape with concern. Though Anna was confident Elsa would thaw it, Kristoff was doubtful.
After some time, Kristoff, Sven, and Anna reached a frozen forest; the three were captivated by the beauty of the ice crystals. However, a nearby voice startled the trio; Kristoff and Anna looked for the source of the noise and were shocked to encounter a sentient snowman. Anna reacted to the strange sight by crying out and kicking the snowman's head, launching it into Kristoff's arms. Unsure what to make of the snowman either, Kristoff tossed the head back to Anna, who tossed it back; after several exchanges Anna threw the head back at the snowman's body, though it landed upside down. Feeling sorry for the snowman, Anna helped him adjust his head.
After having his head righted, the snowman introduced himself as Olaf; Anna introduced herself and her companions to Olaf, though he mistakenly presumed that Kristoff and his reindeer were both named "Sven." While Anna asked Olaf about Elsa's whereabouts, Kristoff examined one of Olaf's twig arms, and was surprised when the dismembered arm slapped him across the face. Now focused on the conversation at hand, Kristoff told Olaf they needed to find Elsa to bring summer back to Arendelle. Despite being a snowman, Olaf reacted quite joyfully to the prospect of summer and enthusiastically led them onward to Elsa.
The ice palace
With Olaf's help, the group progressed quickly, but after some time, they were halted by a steep mountain face. Kristoff noted that scaling the cliff would be a dangerous endeavor, but that didn't stop Anna from trying. However, due to her lack of climbing skills, Anna found herself stuck on the cliff; amused, Kristoff went to help Anna down but stopped shortly when Olaf alerted them that he had found a staircase that would lead them exactly where they wanted. Hearing this Anna decided to swiftly descend by releasing her grip, falling abruptly, yet safely into Kristoff's arms. Despite Anna's recklessness, Kristoff found himself admiring Anna's pluck.
Finally catching sight of Elsa's ice palace, Kristoff and Anna were captivated by the frozen marvel; when Sven was unable to find traction on the icy steps leading to the palace doors, Kristoff decided to have him stay behind while he proceeded onward with Olaf and Anna. As he ascended the staircase, Kristoff marveled at how it was flawlessly constructed from ice. Kristoff regrouped with Olaf and Anna at the palace doors; Anna seemed reluctant to knock but eventually summoned the courage to do so. To her surprise, the door opened, and before heading inside, she asked for some privacy and requested that Kristoff and Olaf remain outside for "a minute." Though Olaf was initially disappointed, he took Anna's request literally and proceeded to count out sixty seconds; seeing no other alternative, Kristoff decided to count alongside the snowman.
As he reached sixty, Olaf eagerly burst through the doors; however, Kristoff remained outside. Eventually, he too entered the palace and went up the stairs to the top floor just in time to see Anna on her knees, struck by Elsa's magic. Kristoff rushed to Anna's side and helped her up, asking if she was all right. Alarmed by Kristoff's appearance, Elsa told everyone to leave her palace. However, Anna stated that she would not leave without her; at this time, Kristoff noticed dark shadows appearing behind the walls of the palace and sensing danger, he suggested to Anna that they leave. But when Anna refused again, Elsa created an enormous snowman to escort Anna, Kristoff, and Olaf outside; after he tossed Kristoff and Anna down the ice steps, the snow monster tore Olaf into separate pieces and threw his parts at Kristoff and Anna. Riled at this rough treatment of Olaf, Anna turned to confront Marshmallow but was restrained by Kristoff, who insisted that she "let the snowman be." Though she appeared to calm down, Anna suddenly whirled back and threw a snowball at Elsa's guard, to Kristoff's dismay. The snowball did no visible damage to the snow monster, yet he was enraged, and after roaring, ice spikes erupted from his joints.
Realizing the danger, Olaf volunteered to distract the snow monster to provide Kristoff and Anna with an opportunity to escape. The duo slid down a steep slope but Elsa's guard managed to keep pace. As he ran, Kristoff noticed Anna breaking away and though initially confused, he was impressed when Anna managed to slow down Marshmallow by causing a snagged tree to snap upright into the monster's path. However, this elation was short-lived, as the two were trapped at the edge of a cliff.
Realizing going down the cliff was the only option, Kristoff prepared himself and Anna for descent by tying a rope and making a snow anchor. But Elsa's snow monster was catching up once more and threw a tree to signal his approach. Moving fast, Anna launched herself from the cliff, pulling Kristoff with her. At that moment, Olaf reemerged, believing that they had eluded "Marshmallow". However, Marshmallow was directly behind his smaller counterpart and stepped towards Kristoff's snow anchor, despite Olaf's attempts to stop him. After flicking Olaf from his leg, Marshmallow grabbed the rope and began to pull Kristoff and Anna to eye-level, smashing Kristoff's head into the cliff in the process. Dazed by the blow, Kristoff dangled uselessly from the rope while Marshmallow told them not to return. After relenting to the demand, Anna grabbed a knife and cut the rope, enabling them to escape Marshmallow's clutches. Though Kristoff and Anna fell two-hundred feet, the soft snow below cushioned their drop.
At the bottom, Kristoff burst out of the snow and helped Olaf reassemble his body. To Olaf's delight, Sven managed to find the group, and the snowman regarded the reindeer warmly. Seeing Anna still trapped in snow, Kristoff went to help and promptly pulled her free. Grateful for his assistance, Anna asked Kristoff about his head, though he dismissed it as nothing and proceeded to ask Anna what they were to do next. As the implications of her failed mission started to set in, Anna began to panic and wondered about Kristoff's ice business. After telling her not to worry about him, Kristoff noticed that Anna's hair was slowly turning white and reasoned it was an effect of being struck by Elsa's magic. However, Kristoff believed his friends could help, claiming he'd seen them heal someone before.
Trying to find a cure
The group made their way to the Valley of the Living Rock, but during this time, Anna's curse was strengthening, causing her to shiver. Concerned, Kristoff brought Anna over to a steam vent for warmth.
