Stitch was created by Dr. Jumba Jookiba to cause chaos throughout the galaxy. Stitch is characterized by his mischievous behavior, which endears him to Lilo, who adopts him as her "dog".
Through Lilo's beliefs in the Hawaiian concept of ʻohana, which means "family", Stitch evolves from an indifferent, destructive creature into a beloved, more conscious being who enjoys the company of his adoptive family on Earth.
