Pix

Pix, A.K.A. Experiment 214, is an illegal genetic experiment created by Jumba Jookiba. He is designed to take bad pictures of people. His one true place is with Mrs. Hasagawa as one of her "cats." When not residing with her, he apparently works as a street photographer. Pix is voiced by Frank Welker.

Lilo & Stitch: The Series
Experiment 214 was the 214th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to take pictures of people in which they look awful. 214 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. Against statistically unlikely (but not impossible) odds, several experiment pods landed in one location: Mrs. Hasagawa's yard, 214's pod being one of them.

At an unknown point, Mrs. Hasagawa mistook 214's pod for an apricot and washed it, activating the experiment. However, as 214 was not a very evil or destructive experiment, he was able to live a peaceful life with her, due to the latter seeing the former as a mere stray cat who needed a home.

When Lilo and Stitch discovered that Mrs. Hasagawa kept several experiments as pets, they thought they were a danger to her and along with Jumba and Pleakley, tried to capture them all. While Pleakley was backing away from Experiment 358, he bumped into 214, who then proceeded to take his picture. He then stuck out his tongue, revealing the developed photo. Pleakley was at first surprised that he looked bad in the picture, with cracked skin and a bloodshot eye, but Jumba then explained that 214 was designed to take bad pictures of people. Stitch then slammed a container over 214, capturing him.

214 and the other experiments were about to be taken away, but were returned to Mrs. Hasagawa when Lilo and Stitch saw how much she cared for them. 214 was then named Pix.

Leroy & Stitch
The first 624 experiments, including Pix, were rounded 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.

Pix participated in the following battle between the experiments and the Leroy clones, but it is unknown what he did.

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 fail-safe.

Stitch! anime
Pix made an appearance in the Stitch! anime along with Frenchfry, Squeak, Tickle-Tummy, and Houdini when Hämsterviel kicked them out for being considered useless. It is shown that he can use his abilities to distort his photos like a funhouse mirror. He makes a second appearance along with Boomer, Slushy, Blowhard, Kixx, and Slugger when Yuna and Stitch visit Tokyo Disneyland.
