Body of Proof (2011)

S1E19 627

Stitch has been enjoying great success in capturing and modifying the Experiments, leading to an inflated ego and a tendency to be insufferable. However, the situation shifts when Pleakley discovers a pod labeled '627' aboard Jumba's spaceship. It turns out that Jumba has been working on a new experiment, but before they can contain it, it escapes! Now in Gantu's grasp, Stitch feels compelled to show he's superior. Unfortunately, he finds himself outmatched, and with 627 proving impossible to rehabilitate, Lilo and Stitch face a dire predicament.
