Dupe, A.K.A. Experiment 344, is an illegal genetic experiment created by Jumba Jookiba. He is designed to clone individuals into multiple replicas, though the individuals' traits are divided between their clones and originals. It is possible for Dupe to reverse the cloning. His one true place is making half-calorie Shave Ice cones with Slushy. He is voiced by Tara Strong.
Lilo uses Dupe to generate 3 clones of herself to have a group of friends like Mertle has, but Stitch interferes and he gets generated into 3 clones instead. Each Stitch has a fraction of the strength and agility that the original had. His episode also features these experiments: 033 Hammerface, 544 Thresher, 609 Heat, and 617 Plasmoid. In the episode "Snafu", he is shown at the Shave Ice stall working with Slushy (523).
Dupe is shown to be fun-loving, childish and immature, due to the fact he was programmed to be one of the younger experiments (along with Mr. Stenchy and Babyfier). Because of this, he is often treated as the baby of the heroes' side, as his powers are neither chaotic nor destructive. He is also very playful, friendly and optimistic.
Dupe is a small golden-yellow monkey/lemur-like creature with relatively flat ears, a brown round nose, black eyes, a white body, a brown-striped tail and brown-striped prehensile appendage protruding from his head. He stands 2 feet 11 inches tall and weighs 43 lbs.
The ray from Dupe's appendage causes any individual or object hit to split into a varying number of duplicates.
Dupe also has a reverse setting which causes his ray to re-merge clones.
Dupe can make duplicates stronger or weaker than the original.
Despite Dupe's ability to generate clones, all of the original's traits (such as strength, power, calories, etc.) will be divided between the clones, making the original very weak, and resulting in the original and clones having less of everything.
Dupe made an appearance in the Stitch! anime where his tweak was altered by Hämsterviel, so instead of making things weaker once duplicated, the duplicates are made stronger than the original, rather than the other way around.
