Stitch is a blue koala-like alien, a fictional character in Disney's Lilo & Stitch franchise. An illegally-made, genetically engineered, extraterrestrial life-form resembling a blue koala, he is one of the franchise's two title characters, alongside his human adopter and best friend Lilo Pelekai, and its most prominent protagonist. Within Disney's Lilo & Stitch franchise, Stitch was created by Dr. Jumba Jookiba to cause chaos across the galaxy. But after being adopted by Lilo, he evolved from an uncaring, destructive creature to a loving, more self-conscious being who enjoys the company of his adoptive family on Earth.
