(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. He notably shows no tolerance for failure, ensuring that underlings do as they're told.

Gantu is a gigantic whale-like/shark-like, grey-skinned alien who towers over most beings. He is also extremely muscular with a perfect and very humanoid body. Dressed in a sleeveless, black captain's uniform with red lining on the uniform's shirt and trousers, this uniform includes a small gold badge, which Gantu pins to the left side of his chest. He also wears black gauntlets over his wrists. Gantu has three fingers on each hand and elephant-like feet with three very short toes and black toenails on the end. His head has some fish-like qualities, an example being a "dorsal fin" on the top of his head's center and a noseless face. Twin, fleshy, curved "tusks" also protrude from either side of his head. His teeth are quite small and come to a slight point. Gantu lastly has slanted blue eyes that lack pupils. A teal holster, strapped to a belt around his waist of the same color, holds his blaster when not in use.)
