Kristoff in Frozen: Who He Is, His Voice and His Story

Kristoff is a working ice deliverer, voiced by Jonathan Groff. He first appears in Frozen (2013), directed by Chris Buck and Jennifer Lee, where he joins Anna in her search for Elsa on the North Mountain. His companion is his reindeer, Sven, and the pair appear together in Frozen (2013), Frozen Fever, Olaf's Frozen Adventure and Frozen II.

The credits are consistent across the saga. Groff is listed as Kristoff (voice) in Frozen (2013), Frozen Fever and Olaf's Frozen Adventure, and the Frozen II (2019) credits list him for the role as well as for Sven and the reindeer. In the short Once Upon a Snowman, the credit reads Kristoff (voice) (archive sound).

What is his personality like? The films show him mostly through what he does for Anna. He joins her search for Elsa, and when the trolls tell him that only an act of true love can save her, he rushes her back to Hans for a kiss. In Frozen Fever he is among the friends who help with the secret birthday preparations.

What was his job in Frozen? He delivers ice, and at the end of Frozen (2013) he becomes the royal ice deliverer. That title ties him to Arendelle for the rest of the saga. If you want to see how he fits among the others, the Frozen characters page lists every main figure.

The ice deliverer's closest bonds are with Sven and Anna, and the rest of his circle forms around them. Does he love Anna or Elsa? The films answer that clearly: he loves Anna. They share a kiss at the end of Frozen (2013), and in Frozen II he proposes to her. With Elsa, the films show him traveling with her, Anna, Olaf and Sven to the Enchanted Forest in Frozen II, and helping her prepare Anna's party in Frozen Fever.

Sven is the constant. The reindeer is at his side from the first film through Olaf's Frozen Adventure, where Olaf takes both the sleigh and Sven to go looking for a tradition. In the Frozen II credits, Groff is listed for Sven and the reindeer as well as for the human lead.

Olaf is often a companion on the road. In Frozen (2013), Olaf joins the trip up the mountain alongside the pair. In Olaf's Frozen Adventure, Olaf borrows the sleigh and sets off on his own, which is an easy way to see how they get along.

The trolls matter to him, too. In Frozen (2013), they tell him that only an act of true love can save Anna, and in Frozen II the troll leader Grand Pabbie tells the sisters they must find out what happened in the past. The cast lists credit Ciarán Hinds as Pabbie in both films.

Hans is his opposite. The ice deliverer races Anna back for a kiss he believes will save her, and Hans turns out to have no interest in saving her at all.

In my opinion, his best moments are the ones where he does something simple and generous, and four stand out across the five titles.

The first is the race back to Arendelle in Frozen (2013). He drives Anna home because he believes a kiss from Hans will save her, which means he is delivering her to the person he thinks she loves. It could be argued that this is the most selfless thing he does in the saga, and it gives the later kiss with Anna more weight.

The second is the sleigh in Olaf's Frozen Adventure. The sleigh catches fire after a piece of coal from Oaken's sauna, races down a mountainside and explodes. The comedy comes from watching the tools of his trade go up in flames while Olaf carries on regardless.

The third is the secret planning in Frozen Fever. He is one of the helpers, along with Sven and Olaf, in Elsa's surprise for Anna, and it is a small reminder that he is part of the family by that point.

The fourth is the proposal in Frozen II. It is quiet next to the flood, the earth giants and the frozen Elsa, but, perhaps, that is why it works. If you are choosing a first film to meet him, Frozen (2013) is rated PG in the US, and Frozen II is also PG. The Frozen movies in order page shows where each fits.
