Bratzillaz Bratzillaz (House of Witchez) is an American line of fashion dolls released by MGA Entertainment in 2012. The dolls, a spin-off of the company's popular franchise Bratz. Bratzillaz are witches with special powers that make each character unique. The Bratzillaz girls are cousins of the Bratz and most of the characters have a similar name to a Bratz character. Starting with the Summer/Fall 2013 doll lines, MGA began to use "House of Witchez" in the main logo to express the Bratzillaz's "witchy" nature. The commercials for the "Back to Magic" and "Witchy Princesses" lines never said Bratzillaz in them, only "House of Witchez".
