Bugby

Bugby, A.K.A. Experiment 128, is an illegal genetic experiment created by Jumba Jookiba. He is designed to turn entire civilizations into harmless bugs. His one true place is helping farmers by turning rocks into aphid-eating ladybugs.Bugby is voiced by Frank Welker.

Bio
Experiment 128 was the 128th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to turn entire civilizations 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.

All of the experiment pods were released and scattered across the island of Kauai, with 128's pod landing in the middle of a farm crop.

Lilo & Stitch: The Series
When the crop was being watered, 128's pod was sprinkled, activating the experiment. 128 was attacked by an eagle, but defeated it by turning it into a dragonfly. 128 then flew off laughing, but accidentally flew into Lilo's jar. Lilo, unaware that 128 was actually an experiment, named him Bugby and took him home, where she put Bugby in her bug city.

When Stitch attempted to eat Bugby, the latter turned Stitch into an ant in self-defence.

Later, when Lilo discovered Bugby in her room outside of the bug city, Bugby turned Lilo into a ladybug.

Jumba and Pleakley shortly after went up to the room to bring Lilo cookies, and the two discovered Bugby.

When Jumba tried to warn Pleakley about Bugby, the latter turned Jumba into a stinkbug, and Pleakley into a praying mantis.

When Lilo, Stitch, Jumba and Pleakley later used a machine to revert to normal (and enlarge three other bugs to human size), Bugby attacked, reverting the giant bugs to their original size. However, Lilo and Stitch were able to capture Bugby before he could turn them, Jumba and Pleakley back into bugs.

Shortly after, Jumba reprogrammed Bugby to turn inanimate objects into bugs instead of people, and sent Bugby onto the same farm where he was activated, where he turned rocks into aphid-eating ladybugs.

Leroy & Stitch
The first 624 experiments, including Bugby, were round 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.

It is unknown whether or not Bugby participated in the following battle between the experiments and the Leroy clones.

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 Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe.
