Experiment 283 was the 283rd genetic experiment created by Jumba with Hämsterviel's funding. He was designed to be as strong as 626.
283 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, 283 was activated, captured, tamed, and named Quarklifter.
Quarklifter is orange, and looks like a mix between some kind of mole and a rhinoceros. He has big, pointy, buck teeth, small ears, and no nose. He has three fingers on each hand and three claws on each foot.
He is designed to be as strong as Stitch.
