Lilo & Stitch: The Series S01E30

Experiment #624 - Angel Experiment #624 has been activated by Gantu, and is used as a secret weapon to try to turn Stitch evil. But because Stitch is more advanced than #624, aka Angel, her evil song doesn't work on either him or 625. Her song does work, however, on the other 623 experiments, so she makes up an army of the experiments on the island. Meanwhile, Stitch tries to get Angel's affections, and Lilo experiences jealousy.
