Finder

Finder, A.K.A. Experiment 158, is an illegal genetic experiment created by Jumba Jookiba. He is designed to sniff out any missing person or item. His one true place is operating a Lost and Found service. Finder is voiced by Frank Welker.

Bio
Experiment 158 was the 158th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to sniff out any lost or missing person or item.

158 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.

Lilo & Stitch: The Series
At an unknown point, Experiment 158 was activated.

When Lilo and Stitch met 158, the former named him Finder and took him home. Finder demonstrated his skills by finding Nani's keys and several other things around the house, which made Stitch envious.

Later, Lilo used Finder for show-and-tell at her school, where he quickly found all of the hula girls' lost belongings, much to Mertle's jealousy.

The Grand Councilwoman later assigned Finder to find an AWOL Hämsterviel. Stitch set out to upstage Finder and prove he was a better tracker than him. When both cousins each pointed in different directions, debating over which trail led to Hämsterviel, Lilo went with Finder, despite Stitch's protests.

Finder tracked Hämsterviel to the Edmonds' house, where Mertle had found the escaped convict earlier at a pet shop and mistook him for a talking gerbil. She then adopted him, confined him in a hamster cage, and planned to use him for show-and-tell. Of course, Hämsterviel became enraged and had a falling-out with Mertle, but eventually adjusted to his new home.

When Mertle tried to cover up for Hämsterviel (after Lilo questioned about his presence), Lilo was convinced that Finder had made an error. Stitch, who knew the truth, attacked Hämsterviel later that night, but the latter blasted Stitch with a makeshift cannon, knocking him unconscious. The noise alerted Mrs. Edmonds, who noticed Stitch and took him to the dog shelter.

The next day, Lilo and Finder arrived at the dog shelter to retrieve Stitch, who revealed to them that Finder had indeed tracked down Hämsterviel.

Lilo, Stitch and Finder returned to the Edmonds' home to discover that Gantu had fled with Hämsterviel in his ship, but also kidnapped Mertle. Stitch and Finder then decided to team up to rescue her. Using his helicopter-like flying ability, Finder tracked down Gantu's ship while carrying Stitch, who then disabled the ship, thereby saving Mertle.

Due to Gantu's blunder, the Grand Councilwoman (who had offered Gantu an opportunity to capture Hämsterviel earlier) did not reinstate him to his former position.

Shortly after, Finder was found a one true place operating the beach Lost and Found service.

In "Drowsy", Finder's picture was seen in Lilo's experiment scrapbook.

In "Skip", Finder was one of the wanted fugitives in an alternate future where Hämsterviel ruled Earth.

In "Ploot", Finder was one of the second team of experiments (along with Babyfier and Drowsy) formed to try and stop Ploot. However, Ploot was easily able to defeat them.

In "Snafu", Finder was one of the experiments who joined Lilo and Stitch on a mission to rescue Gantu's captive experiments. Finder helped break into the ship and free the captive experiments.

Leroy & Stitch
The first 624 experiments, including Finder, 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.

Finder 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.

Personality
Finder is a resourceful, helpful and beneficial tracker. He is also friendly, innocent and brave.
