Stitch — Lilo & Stitch (2002)

Six limbs, four arms when he wants them, and absolutely no respect for personal property. Stitch arrived on Earth as Experiment 626, a genetically engineered chaos machine built to destroy everything in his path. Instead, he found Lilo, learned about ohana, and became the kind of little blue troublemaker people would defend with their lives. That's what makes Stitch dangerous in this competition. He's hilarious, ridiculously cute, surprisingly powerful, and capable of delivering an emotional gut punch when you least expect it. E.T. might be the original alien you want to hug, but Stitch brings a completely different kind of energy. He's got mischief, heart, and a face you recognize instantly. Can the galaxy's biggest troublemaker win the whole thing?
