544 - Thresher

Thresher, A.K.A. Experiment 544, is an illegal genetic experiment created by Jumba Jookiba. He is designed to smash up crops with his mace-like tentacles, although he can also use them to attack and battle enemies. He was captured by Gantu, but was rescued in "Snafu". His one true place is working at the Keo Farm with the local farmers, using his tentacles to chop the sugar cane stalks. He is voiced by Tom Kenny.

He was stolen, named and trained by Gantu, along with Hammerface (033), Heat (609), and Plasmoid (617), turned into an army of 100 weaklings by Dupe (344), and rescued by Lilo's rescue team in "Snafu".


Thresher is a small purple, roughly slug-like experiment with a slim body, a wide mouth, two light green eyes on two stocks, six spiky mace-like stretchable tentacles and three short legs. In his mutated form, he looks more muscular and has bright orange eyes.

Special Abilities

Thresher can thrash crops or beat his victims up using his six extendable, mace-like tentacles.

Thresher has shown to be skilled in playing the marimba.


Like other experiments, when Thresher is divided by Dupe into a hundred replicas, each one will be virtually harmless.


Thresher made an appearance in the Stitch! anime where Hämsterviel used him to attack Stitch during a magic show. In this episode, he looks more muscular and has bright, orange eyes.
