Unikitty

Unikitty once burst, unexpectedly, out of the Doctor's TARDIS, shortly after the Twelfth Doctor had stepped out, with colourful stars appearing around her. She was later jumping excitedly in front of a LEGO Gateway while a child was placing Scooby-Doo and the Ecto-1 onto the gateway. She usually had an overly pink, white, and blue colour scheme but, when angry, she had a more red and yellow appearance. (NOTVALID: Endless Awesome)
