Pleakley is the former antagonist of Lilo and Stitch and an ally of the two main protagonists. He is a walking noodle one-eyed alien with three legs, two figured arms and he would wear a orange mumu with leaf patterns, but he used to wear a blue suit and yellow sholder holders. He is flamboyant, funny, witty and a neat freak and is obsessed with saving the mosquitos since he believes they are a endangered species. He is voiced by Kevin McDonald.
In the first movie, Pleakley, seemingly being an Earth expert, is first called fourth by the Grand Councilwoman after the fugitive Experiment 626 crash landed on the planet Earth. Pleakley requests back-up through someone with a strong affiliation with 626 in order for the capture to go smoothly. He is paired with 626's creator Dr. Jumba Jookiba. The duo travel to Earth and land in Hawaii, where Stitch currently resides. They quickly spot him exiting an animal shelter with a human girl named Lilo. Jumba nearly blasts both Lilo and 626 (now named "Stitch" by Lilo), but Pleakley interferes and prevents the blast. He feels the human race shouldn't be affected by the hunt in any way and that they should disguise themselves to blend in.
However, Jumba realizes Stitch is simply using Lilo as a human shield, which he claims is low even for Stitch himself. For the entire day, Jumba and Pleakley followed Stitch all over the island and that night, at a luau, they make their first attempt, using alien bait (a green, amethyst-spotted chicken-like drumstick) to lure Stitch to them, but Stitch bites on to Pleakley's head before he is able to handcuff him. Nani, Lilo's older sister, arrives and removes Stitch. Later on that night, Pleakley and Jumba rested on a hill overlooking Lilo's home where they have a perfect view of Stitch.
The next day, at the beach, Pleakley and Jumba once again make an attempt to capture Stitch but fail yet again. Soon after their latest fail, the Grand Councilwoman contacts Pleakley and fires them. As a result, Jumba now has no restrictions on the capture of Stitch and can cause as much destruction as he wants. After a destructive battle in Lilo's house with Stitch, Lilo is accidentally kidnapped by Gantu, who was hired by the Grand Councilwoman to capture Stitch in place of Pleakley and Jumba. The duo successfully capture Stitch anyway, but are confronted by Nani, who witnessed Lilo's kidnapping and blamed Stitch for it. Jumba agrees to help Nani and Stitch rescue Lilo with Pleakley joining reluctantly. They chase after Gantu with their ship. Stitch successfully rescues Lilo and when they return to the island, the Grand Councilwoman leaves Stitch in the custody of Lilo and Nani. Jumba and Pleakley are also left behind on Earth and become additions to Lilo's "ohana".
In Lilo and Stitch 2: Stitch Has a Glitch, Pleakley (now living with Lilo and Nani) has become comfortable with his new life on Earth, but soon enough, Stitch becomes out of control during a family movie night. Jumba fears the worst and heads to his ship, having Pleakley follow. Pleakley spends most of his time trying to find out what's wrong with Stitch and beholds a chilling discovery: Stitch is on the verge of death. Together, Pleakley and Jumba work together to create a machine to save Stitch.
A side story involving Pleakley revolves around David, who believes Nani is losing interest in him. Pleakley comes to his aid and tries to give advice on romance.
In Stitch! The Movie Pleakley appears in the film, trying to help free Jumba from Gantu and Dr. Hamsterviel. He is now referred to as Lilo's "aunt". At the end of the film, Pleakley tries to return home, but the ship leaves without him and Jumba. He then accepts the fact that he's on Earth and teams up with Lilo, Stitch and Jumba to capture the experiments.
In the television series, Pleakley is a main character, appearing in almost every episode. Like his previous appearances, he is under the guise of Lilo's "aunt" and is rather easily fascinated by what he and Jumba call "primitive earth technology and customs" such as comic books and reality television.
In one episode, he had a brief mock engagement with Nani to placate his pushy visiting mother. In this same episode, he also had a mock engagement to Jumba. Pleakley's mother is concerned that he has not found "the right girl" and that he is not married. Pleakley feels he must pretend to be married for his mother to approve and accept him. When his family arrives on Earth for the mock wedding of Nani and Pleakley, he reveals that he is happy being who he is, which includes being unmarried. After that, his family becomes more understanding of him and loves him for who he is.
