Wrapper

Wrapper, A.K.A. Experiment 521, is an illegal genetic experiment created by Jumba Jookiba. He is designed to mummify people in tape. His one true place is with Mrs. Hasagawa as one of her "cats."

Bio
Experiment 521 was the 521st genetic experiment created by Jumba with Hämsterviel's funding. He was designed to mummify people alive in tape.

521 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.

All of the experiment pods were released and scattered across the island of Kauai. 521's pod was one of the many experiment pods that landed in Mrs. Hasagawa's yard.

Lilo & Stitch: The Series
521's pod was found by Mrs. Hasagawa along with numerous other pods.

When Lilo and Stitch visited Mrs. Hasagawa, she, mistaking the experiment pods for apricots, offered them to Lilo and Stitch, but not before washing them and thus activating the experiments.

Lilo, Stitch, Jumba and Pleakley captured 521 and the other experiments, but returned them to Mrs. Hasagawa when they saw how much she cared for them.

Leroy & Stitch
The first 624 experiments, including Wrapper, were round up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.

It is unknown whether or not Wrapper participated in the following battle between the experiments and the Leroy clones.

The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song Aloha Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
