Cyber, A.K.A. Experiment 000, is an illegal genetic experiment that is the first and oldest experiment created by Jumba Jookiba before he began numbering his creations. He is designed to be the ultimate killing monster and appears as an antagonist in the second season of Stitch!.
He was the first experiment created before Jumba started assigning numbers to his experiments, though Jumba later refers to him as "Experiment Zero" in his eponymous debut. Jumba was attempting to create the ultimate killer monster, and he was successful. However, his success also resulted in him being unable to control the experiment. Eventually, Jumba was forced to suspended Experiment 000's cell activity and imprison him on an icy planet. Experiment 000 was eventually able to escape and acquired mechanical body parts, making him even more powerful, and became a ruthless warlord with a cyborg army in the galaxy. When Experiment 000 targets Hanpipi Nebula, the Grand Councilwoman contacts Stitch to help defeat him. Experiment 000 puts up a fight at first, but he was eventually defeated and captured by Stitch. Once restrained, Experiment 000 reveals he has a supernova warhead and then initiates its launch toward the Grand Council's headquarters on Planet Turo, threatening the entire galaxy. Stitch was able to redirect the warhead into a black hole forming nearby, saving everyone. It is unknown where Experiment 000 was taken after his defeat.
Experiment 000's resemblance was close to a purple version of Stitch. Originally 100% organic, Experiment 000 is now a cyborg, part machine, part alien. His organic body now black while the rest is mostly metal alloys and reinforced plastic. His form resembles a cross between a type of lizard and koala (and robot). He has a two cyborg arms, three spider-like legs, and half-helmet with a cyclonic-like right eye from some unknown incident. His cyborg arms serve many purposes such as cybernetic wiry rope, laser guns, a forked harpoon and welding tool, and his cyborg eye has zoom functions and improves his aim. In cyborg form, he is missing his nose.
In his original form, Experiment 000 has all the powers of Stitch. In his cyborg form, his cyborg arms serve many purposes such as cybernetic wiry rope, laser guns, a forked harpoon and welding tool, and his cyborg eye has zoom functions and improves his aim. He can manufacture many weapons such as android minions, spaceships, and a doomsday device (supernova warhead).
