Remmy

Remmy, A.K.A. Experiment 276, is an illegal genetic experiment created by Jumba Jookiba. He is designed to turn dreams into nightmares. His one true place is sending gamers into virtual realities. He is voiced by Jeff Bennett.

Bio
Experiment 276 was the 276th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to enter enemies' dreams and transform them into nightmares.

276 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, with 276's pod landing in a turtle's nest.

Lilo & Stitch: The Series
When a sea turtle discovered 276's pod in its nest, it threw the pod out, which landed in the path of the incoming tide, activating 276.

276 traveled to the Pelekai household, where he invaded Lilo's dreams.

Stitch, Jumba and Pleakley entered Lilo's dreams to capture 276, who was dissolving Lilo's dream. The four tried to suck 276 up with a vacuum, but 276 was able to use a fire hydrant to block the nozzle. Angered at the four's attempt to capture him, 276 replaced Lilo's dream with a happier one which later turned into a nightmare.

Nani attempted to wake Lilo up, but was stopped by Pleakley, who had exited the nightmares.

When the monsters in the nightmare had Lilo, Stitch and Jumba cornered, Pleakley returned into the nightmare, and gave Lilo a photo of her parents. The photo allowed Lilo to remember the happy times she had with her parents and overcome 276's power, destroying the nightmare and defeating 276, who was shortly after captured and extracted by Jumba.

After 276 was defeated, he was named Remmy and was reprogrammed by Jumba to send gamers at the local arcade into virtual realities of their fantasies.

Leroy & Stitch
The first 624 experiments, including Remmy, 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 Remmy 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.
