Gantu appreciates his position of authority amongst the military forces of his world, but his great size and superhuman strength often lead him to underestimate those smaller than he is. Lilo calls him 'Big Dummy' for most of the series.
When he is seen by humans on Hawaii, he typically attempts to pass himself off as a Samoan, though Lilo once told Mertle he was a dogcatcher from Nairobi, which the other girl believed. He wears a black battle shirt with black pants and stands 20 feet tall. An extremely large and muscular alien with a gruff, militant personality, Gantu resembles a bipedal whale or shark with grey skin, sky blue eyes, and elephant-like feet. Gantu, also known as Captain Gantu during Lilo & Stitch, the end of Leroy & Stitch, Stitch & Ai, and in other spin-offs, is Lilo and Stitch's former archenemy, serving as the main antagonist of the original film, the secondary antagonist of Stitch! The Movie and Lilo & Stitch: The Series, and eventually teaming with Lilo and Stitch on the hero side during Leroy & Stitch. Being yelled at or insulted (especially by Hämsterviel).
