Leroy & Stitch

After completing their mission, the team is celebrated as heroes by the Galactic Alliance. They are offered prestigious roles: Jumba returns to his laboratory, Pleakley becomes chairman of Earth Studies, Stitch is named Captain of the Galactic Armada, and Lilo is appointed ambassador to Earth and guardian of the experiments. The aliens initially decline the offers out of loyalty to Lilo, but she ultimately allows them to pursue their new adventures.

Before departing, Lilo, Jumba, Pleakley, and Stitch exchange keepsakes that symbolize their bonds. Lilo gives Jumba her Elvis Presley record, Pleakley a small rock as a paperweight, and Stitch a tiki necklace. These gifts reinforce their friendship as they head into new roles.

Gantu breaks Hämsterviel out of prison, abandoning Experiment 625 in the process. Hämsterviel hatches a scheme to build a new Stitch-like creature named Leroy. The plan sets up fresh trouble that will pull the heroes back into action.

On Earth, Lilo attempts to contact Stitch using the intergalactic videophone aboard Gantu's ship. She meets 625 and renames him 'Reuben' after he repairs the device. Lilo finally reaches Stitch through the BRB-9000, but Leroy impersonates Stitch.

Lilo notices that the impostor isn’t wearing Stitch’s tiki necklace, revealing the ruse. Realizing Stitch is in danger, she coordinates with Reuben to help rescue him. The stakes rise as Leroy continues impersonating Stitch to sow confusion.

Lilo has Reuben repair Gantu's ship and head toward a black hole. Stitch breaks free from his capsule and helps the others escape. He disrupts the black-hole's event horizon by tossing Pleakley's rock into it, enabling their escape.

Leroy captures Lilo's scrapbook of the experiments and Mertle Edmonds. Lilo and Reuben head to Turo to retrieve them, but Hämsterviel has already taken over there and orders Gantu to imprison them, discarding him. Gantu, however, eventually helps Lilo and Stitch escape.

After a turn of loyalties, Gantu helps Lilo and Stitch escape and they return to Earth aboard the Galactic Alliance vehicle.

Leroy and Hämsterviel gather the experiments at Aloha Stadium and prepare to kill them with the BRB-9000's cannon. The heroes arrive to stop the attack and destroy the cannon, but Hämsterviel releases the Leroys to overwhelm the other experiments.

Jumba reveals he programmed a secret shutdown into Leroy that activates when he hears Elvis Presley’s rendition of Aloha Oe. The team interrupts the battle to trigger the song, and the Leroys’ command is activated, turning the tide in the heroes' favor.

With the threat neutralized, the group is once again honored by the Galactic Alliance. Stitch, Jumba, and Pleakley ask to return to Earth with Lilo, and the Grand Councilwoman reinstates Gantu as captain of the Armada, with Reuben serving as a galley officer.

Back on Earth, Lilo prepares for one final 'ohana' photo with her family and Mertle Edmonds. The moment underscores the strengthened bonds and the promise of future adventures.

In the closing moments, Hämsterviel is recaptured and imprisoned again, along with the Leroys. The credits reveal an almost complete list of Jumba's experiments, hinting at future adventures.
