Agent Wendy Pleakley hails from Plorgonar, originally employed as the Galactic Federation's Earth expert. His physical form features a slender beige-green body dominated by a large central eye, three legs each ending in two-toed feet, three elongated fingers per hand, and a single antenna serving as both ear and nose. Internally, he lacks a skeletal structure and possesses an extremely small brain. Tasked with capturing the fugitive Experiment 626 (Stitch) on Earth, Pleakley partners with its creator, Dr. Jumba Jookiba. His proclaimed Earth expertise proves largely theoretical and frequently incorrect, exemplified by his belief that mosquitoes are endangered. To blend in, he adopts a human disguise including a brown wig and women's attire. Repeated failures to apprehend Stitch result in both Pleakley and Jumba being fired by the Grand Councilwoman and stranded on Earth. Marooned in Hawaii, Pleakley integrates into Lilo Pelekai's extended ʻohana, becoming a permanent resident with Jumba and Stitch. Contrasting Jumba's mad science inclinations, Pleakley exhibits a gentle, nurturing disposition, assisting with domestic chores like cooking, cleaning, and childcare. He develops a deep appreciation for Earth's culture and environment, though sometimes criticizing its "primitive" technology, and misunderstands the frequency of Thanksgiving, preparing monthly dinners. His character development involves reconciling his identity with familial expectations. When his mother visits, he stages mock engagements with both Nani Pelekai and Jumba to address her concerns about his unmarried status, ultimately declaring his contentment with being single and gaining acceptance. Exposure to a fear-inducing experiment reveals his worst fear is disappointing his mother. In later adventures, Pleakley relocates to Okinawa's Izayoi Island with Jumba and Stitch, joining Yuna Kamihara's household. Within this continuity, he and Jumba are initially stranded on an asteroid in Saturn's rings before reuniting with Stitch on Earth. Pleakley aids Stitch's quest to accumulate good deeds using Jumba's "Good Deed Counter," supporting Yuna and Stitch against experiments and threats like Dr. Hämsterviel. Pleakley accepts a position as Head of Earth Studies at Galactic Alliance Community College but resigns due to dissatisfaction and loneliness, returning to Earth to rejoin his ʻohana. His consistent traits encompass loyalty to his found family, comedic panic during crises, and a blend of emotional vulnerability and resilience across all appearances.
