Koslov

Koslov is a character from the Disney animated feature film, Zootopia. He is Mr. Big's most trusted henchman, and a member of the Tundratown mafia.

Role in the film
After being captured by some of Mr. Big's henchmen, Raymond and Kevin, Nick Wilde (who Big holds a personal grudge against) and Judy Hopps are taken to the crime lord's lair. When Koslov appears, Judy believes him to be "Mr. Big", but after taking a seat at his desk, Koslov reveals Big to be an arctic shrew.

During the end credits, Koslov is seen enjoying the music of Gazelle's concert with a stoic expression, while Mr. Big and his daughter, Fru Fru, dance together in his palms.

Trivia

 * On some promotional material, Koslov's name was incorrectly written as Kevin.
 * In early drafts and promotional material for the film, Koslov was spelled as Kozlov. As opposed to Mr. Big, Koslov was going to be the antagonist encountered in Tundratown, having a larger role as a Russian gangster and the owner of a restaurant called Koslov's Palace. He was also planned to have a son named Morris.
 * Koslov is shown to be Catholic, as he is seen crossing his chest in prayer during the film.
 * In some promotional materials, Koslov's sweater is colored blue.
