Kaliko is a fictional character from L. Frank Baum's Oz series. He is a nome and lives in the Nome Kingdom, where he is, at least to start off with, the Chief Steward to his sadistic master, the Nome King Roquat the Red.
Kaliko is first encountered in Ozma of Oz, though he is identified only as the Chief Steward. The character of Kaliko is in his prime in Tik-Tok of Oz. Kaliko become king after old Ruggedo (whose name was changed from Roquat) was expelled from his kingdom by the Great Jinjin Tititihoochoo for tipping some members of a Resuce Expedition from Oz down a Hollow Tube and straight into the Land of the Fairies, which is under the governorship of Tititihoochoo. Kaliko promises to become a good king and offers to assist in rescuing the Shaggy Man's brother. Ruggedo returns to the Nome Kingdom, and Kaliko takes him in upon Ruggedo's promise to be good.
Kaliko has a brief role in The Emerald City of Oz and Rinkitink in Oz. He also makes appearances in the later Oz books of Ruth Plumly Thompson, where he appears to have changed from a 'good' Nome into a cruel Nome who harbours plans to rule Oz for himself, and adds himself to the list of Princess Ozma's enemies. He is afraid of eggs; and once he becomes king, he is a self-confessed 'powerful sorcerer'.
