Stitch is an alien (Experiment 626) that was made by Jumba. He escaped from the Intergalatic Federation(IF) and crashed on Hawaii. Lilo and Nani, found him at the pound and took him home. Lilo introduced him to a variety of things on their island adventures. Stitch learned how to be good and the definition of Ohana! Jumba and Pleakley were sent to apprehend Stitch for the IF, but they joined the family instead! There's four movies in the franchise and the second one is my favorite!
