Unikitty is a half unicorn and half kitten (hence her name) who wants to help Emmet, Wyldstyle, Batman, Benny, Metalbeard, and Vitruvius to save the Lego world from the Evil Lord Business. She usually tries to be sweet all of the time, but when she gets mad, she becomes crazy and deadly. She is a major character of The LEGO Movie and The LEGO Movie 2: The Second Part, and the main protagonist of the TV show of the same name.
She was voiced by Alison Brie in the films, The Lego Movie: 4D – A New Adventure, and LEGO Dimensions.
