Leonardo, Michelangelo, Donatello and…Roseanne Barr?

The actress will guest-star on the season-finale of Teenage Mutant Ninja Turtles, EW has learned. Barr will voice Kraang Prime, the Kraang’s glorious leader from Dimension X, and the first look photo — full of multiple eyes and purple skin — is certainly a bit creepy.

Teenage Mutant Ninja Turtle‘s season finale with Barr will air on Nick later this summer.
