What is the name of the unicorn-cat character in The Lego Movie?

The unicorn-cat character in The Lego Movie is named Unikitty. She is a pink, highly energetic Master Builder who rules Cloud Cuckoo Land, a fantastical place designed around happiness and imagination.

Unikitty is described as a hybrid of a unicorn and an anime-style kitten. Her cheerful personality has a hidden explosive side: when pushed too far, she transforms into a larger, fierce version of herself. This contrast became one of the character’s main comedic traits in the film.

Alison Brie provided Unikitty’s voice in The Lego Movie and The Lego Movie 2: The Second Part. The character later received her own Cartoon Network series, Unikitty!, which premiered in 2017 and featured Tara Strong as the speaking voice. That television series expanded her world into the Unikingdom and introduced characters including Prince Puppycorn.
