Stitch is fictional character and the main protagonist in the Disney animated movie "Lilo and Stitch." He is an alien experiment created by the evil genius Jumba Jookiba. Stitch is a furry blue creature with sharp teeth, four arms and two antennae. He was designed to be a highly intelligent and destructive creature, but he became endearing to the movie's main character, Lilo, and gradually learns to become a loving and loyal pet.
