When 626 soon after saw Lilo looking for a pet dog, he saw her as an unaware hostage and altered his appearance to look less otherworldly and pose as a dog in order for her to adopt him. When 626 awoke, he attempted to escape the shelter but was forced to retreat back inside by an attack from his own creator. Shortly after landing, 626 was run over by a convoy of trucks, knocking him out, and taken to the local dog shelter. 626's cruiser was soon fired upon by a fleet of police cruisers, and, in an attempt to escape, 626 activated his cruiser's hyperdrive, but the damage inflicted on the police cruiser by the fleet caused it to exit hyperspace over Earth and crash on the island of Kauai. However, 626 was able to escape his detention cell (thanks to the incompetence of the lieutenant left to guard him) and steal a federal police cruiser. When 626 replied to the Grand Councilwoman's attempts to reason with him with an obscene phrase, he and Jumba were declared guilty, and 626 was escorted by Captain Gantu to be exiled on a desert asteroid. Jumba and 626 were taken to the planet Turo to stand trial. Shortly after his creation, the intergalactic police arrived to arrest 626 and Jumba, preventing 626's molecules from being fully charged in the process. Jumba Jookiba from six or more of the galaxy's deadliest predators, though instead of him appearing vicious, he appeared to be cute and fluffy.
He was designed to be virtually indestructible, fireproof, bulletproof, shockproof, think faster than a supercomputer, have super sight and hearing, and lift objects 3,000 times his own weight (but not an ounce more).
