Stitch (also known as Experiment 626, pronounced "six-two-six") is a fictional character in the Lilo & Stitch franchise. Originally created to cause chaos across the galaxy, he is marked by his mischievous behavior, traits that endear him to his friend Lilo (who adopted him as her "dog"). He is voiced by his creator and the film's co-director, Chris Sanders, in almost all media that the character appears in.
