Kronk is the secondary antagonist turned supporting protagonist in The Emperor's New Groove and the titular protagonist of Kronk's New Groove. He is Yzma's former henchman and one of Kuzco's best friends. Because he saved his life from Cat Yzma.
He was voiced by Patrick Warburton who is best known for the voice of Joe Swanson from Family Guy.
In the Emperor's Groove, Kronk helps Yzma to kill Kuzco by poisoning him but instead it turns Kuzco into a llama. Yzma later sends Kronk to drop Kuzco over a waterfall but decides to drop in Pacha's cart thanks to his conscience. He later has a change of heart after Yzma admits that she hates his spinach puffs.
In the TV series The Emperor's New School, he is an anti-heroic character who is both a friend of Kuzco and Yzma's henchman. He eventually redeems himself in the last episode and becomes Kuzco's advisor. Kronk also helps Kuzco.
Kronk starts as Yzma's loyal assistant, helping her with tasks where she is too old to do things herself. Kuzco and Yzma early on discuss awkwardly how he is a young, handsome man in his mid-to-late twenties. Despite working for Yzma, Kronk is not evil, in fact he has a shoulder angel and shoulder devil who appear on his shoulders as his subconscious whenever Kronk faces a moral dilemma. They are smaller versions of Kronk dressed in an angel and devil costume and usually bicker and mock one another. Sometimes, of course, they agree with each other, as they (and Kronk) think a chandelier will trap Yzma for criticizing his spinach puffs.
Kronk is also shown to be Jewish. In Kronk's New Groove, he fantasizes about marrying Miss Birdie in a Jewish ceremony, complete with him, stepping on a glass.
