Anna is the main character of Frozen.
When Anna and her sister, Elsa, were little, Anna got struck in the head by Elsa's powers, which turned a string of her hair white. The trolls were able to heal her, but they erased any knowledge of Elsa's powers, while keeping the fun memories intact. Anna grew up wanting to play with Elsa, but since her older sister shut herself inside her room, the two grew more and more distant.
Years later, during Elsa's coronation, Anna met a young prince named Hans, and fell in love with him. She asked Elsa for her blessing, but when Elsa refused, Anna confronted her about being distant all their lives. Elsa, in a rage, revealed he r snow powers and fled. Despite everyone else labeling Elsa a monster, Anna decided to go after her. Along the way, she met Kristoff and his reindeer Sven, and a talking snowman named Olaf.
Anna is shown to be caring and kind, but also full of spunk. She is able to carry her own, but in her heart, she loves her sister very much, even going as far as to give her life for her.

As she once again began to flee the country, she was informed by Hans that Anna had died from a frozen heart. In her despair, she fell to her knees. Unknown to her, Hans wished to kill her, but as he brought down his sword, Anna (who was not yet frozen), ran between them and blocked the blade. Hans became incompacitated, but Anna froze solid.

Kristoff is a main character in Frozen.
He grew up with trolls and his pet reindeer Sven. He sells ice for a living. He first meets Anna when she is out looking for Elsa, and agrees to help her in her journey. He is very critical of Anna's love for Hans; he believes, as Elsa does, that true love cannot appear in a matter of hours.
After Anna is hit in the heart by Elsa, Kristoff takes her to see his troll family. Afterwards, he helps her get back to Arendelle to be with her true love. However, as he is leaving, he realizes that he loves Anna, so he goes back to save her.
Kristoff hates being called "Christopher", and absolutely adores ice. He writes songs and sings them with Sven, his only true best friend.

Olaf is one of the main characters in the film Frozen. When Anna and Elsa were younger, they created a snowman and named him Olaf when they played in the snow.
Elsa created a living snowman as she fled Arendell as an adult, and the snowman based itself on the one she created as a child. Anna and Kristoff encountered Olaf on their quest to find Elsa. He joined them, and later, helped to keep Anna warm after Elsa froze her heart.
Olaf loves warm hugs, and throughout the film, constantly expressed interest in knowing exactly what "warm" was. After Elsa thawed Arendell, he was given a personal cold spot, which hovered above him no matter what, to make sure he would never thaw.
