Skeletor's falcon, portrayed in the Filmation series as a robot with a display screen on its chest.
Screeech is Skeletor’s falcon and the dark counterpart to Zoar. The Filmation series makes an unusual choice with him: here he is explicitly robotic, with a large display screen set into his chest, where most other portrayals across the Masters of the Universe franchise treat him as a living bird.
His scale is inconsistent, which the series uses freely. In Fraidy Cat he is large enough for Cringer to leap onto his back while escaping Snake Mountain. In Visitors from Earth he is used to carry an explosive to Castle Grayskull. He also appears in The Toy Maker.
He is given no dialogue in the Filmation series and no voice actor is credited for the character.
