Cyber "000"

Cyber is an Experiment 000 that is a purple version of Stitch with the same abilities, but he is turning into a black, cyborg experiment, part machine part alien. His alien form resembles a cross between some sort of lizard, and koala (and robot). He's sort of Stitch!'s main antagonist. He has a two cyborg arms, three spider-like legs, and half-helmet with cyclopic-like right eye from some unknown incident. His cyborg arms serve many purposes such as cybernatic wiry rope, laser guns, forked harpoon, and welding tool, and his cyborg eye has zoom functions and improves his aim.

Stitch!
He is an evil experiment that is a cyborg version of Stitch. He then attempts to put an early ending to their emerging rivalry by proceeding in kidnapping Angel in Season 3.
