XYZ, A.K.A. Experiment 153, is an illegal genetic experiment created by Jumba Jookiba. She is designed to unzip people's pants while they are being worn. Her one true place is at the fashion store, opening pants zippers for people.
Experiment 153 was the 153rd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to unzip people's pants while they are being worn.
153 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.
At the unknown point, she was activated, captured, tamed and named XYZ.
- XYZ was mentioned in the anime by Pleakley as a pant zipper opener.
