Bugby, A.K.A. Experiment 128, is an illegal genetic experiment created by Jumba Jookiba and a character in the Lilo & Stitch franchise. He is designed to turn entire civilizations into harmless insects. Those turned into bugs can understand all other insects and arachnids; only Jumba's technology can reverse the process. His one true place is on a farm, protecting farmers' crops by turning rocks into aphid-eating ladybugs.
Experiment 128 was the 128th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to turn people into harmless insects. 128 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
When the crop was being irrigated via sprinklers, 128's pod was sprinkled, activating the experiment. 128 then took flight and traversed the island of Kauai aimlessly.
128 was soon attacked by an eagle, but defeated it by turning it into a dragonfly. 128 then fluttered off laughing, but accidentally flew into Lilo's jar. Unaware that 128 was actually an experiment, Lilo named him Bugby and took him home, where she placed Bugby in her makeshift bug city, Bugopolis.
When Stitch grabbed Bugby and attempted to eat him, the latter turned Stitch into an ant in self-defense.
Later, when Lilo noticed Bugby in her bedroom outside of Bugopolis and went to check on the other bugs, Bugby turned Lilo into a ladybug.
Shortly after, Jumba and Pleakley went up to Lilo's room to bring her gravel muffins (which Jumba deemed inedible), and the two discovered Bugby loose, which actually intrigued Pleakley. When Jumba then tried to warn Pleakley about Bugby, the latter turned Jumba into a stink bug and Pleakley into a praying mantis.
The four later befriended a dung beetle, spider and caterpillar, though the trio believed Stitch was evil since he ate insects like them. However, when the three bugs were in danger of insect-hating Nani and the exterminator, Stitch rescued them and eventually had a change of heart about eating bugs.
After a few setbacks, including a tussle with an aggressive wild cat, the gang used a special machine on Jumba's ship to revert to normal (and enlarge the three real bugs to human size). When the exterminator showed up, thinking the vermin crawled into here, the leader of the giant bugs told the exterminator off, scaring him away.
Bugby then attacked, reverting the giant insects to their original size. However, Lilo and Stitch were able to recapture Bugby in Lilo's jar before he could turn her, Stitch, Jumba and Pleakley back into bugs.
Shortly after, Jumba reprogrammed Bugby to turn inanimate objects into bugs instead of people. The latter was then found a one true place on the same farm where he was first activated, where he turned rocks into aphid-eating ladybugs, thus helping farmers protect their crops from unwanted pests.
The first 624 experiments, including Bugby, were rounded up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.
Bugby participated in the following battle between the experiments and the Leroy clones probably by turning attacking Leroys into insects.
However, the Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song "Aloha ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
Bugby is a small green, mosquito-like experiment with four purple eyes, four wings and six teal legs.
Bugby can fire a purple laser from his stinger that causes people hit to turn into bugs and giant insects hit to revert to the normal size of bugs. Anyone turned into a bug can communicate with all other insects and arachnids. His ray can also, if reprogrammed, turn inanimate objects into bugs instead of people.
The only way to reverse Bugby's effects is with a machine built by Jumba. The machine can also enlarge normal-sized insects to the size of average human beings.
- Bugby is one of the only experiments that Stitch didn't instantly recognize as a fellow cousin.
- Bugby is essentially reprogrammed to create life out of inanimate objects.
- Bugby's pod color is purple.
- In his debut, Bugby's eyes are purple, but in Leroy & Stitch, they are black.
- Bugby is one of the few experiments to not appear in the group photo at the end of Leroy & Stitch.
