Family
Stitch, also known as Experiment 626, was created By scientist Jumba Jookiba and considers Lilo and Nani to be family. He also has 627 "cousins", Alien experiments created by Jumba before Stitch.(with the exception of 627 and 628 which Jumba made when he was annoyed at Stitch's arrogance.)The green, one-eyed alien named Pleakly is also considered family.

Initial Programming
While explaining his creation to the Galactic Council early on in Lilo & Stitch, Dr. Jumba gives the following rundown of Stitch's powers: "He is bulletproof, fireproof, and can think faster than [a] super computer. He can see in the dark and can move objects 3,000 times his size. His only instinct - to destroy everything he touches!"

Stitch was created to destroy, hate, and kill. Jumba's reasoning for his creation and purpose are unknown. He gathered DNA from the most ferocious creatures and fused them together. Unfortunately for him puppy DNA was accidentally mixed into the machine and made stitch koala-like.
