Prince Grus is a Marine Rear Admiral posted at the G-14 Marine base and serving in the covert SWORD unit. He eats the Gunyo Gunyo no Mi to mold and command clay golems, and his colleagues address him by the separate honorific "Prince" even though it is not his surname.
Green, fluffy, and shaggy hair sits atop Grus, a well-built young man whose eyes are purple. A brown fur coat drapes across an open red shirt baring his chest, the shirt bearing two vertical white stripes along its left flank, plus a golden chain ringing the collar. He pairs red trousers, secured with a black belt and gold buckle, with black laced footwear. His most striking feature is a Marine cap fitted with an enormous bill that is red along its underside, and he slips rings onto each of the four fingers of his right hand. At first he sports the coat slung across his shoulders, later wearing it properly with both arms through the sleeves.
Level-headed and composed, Grus sticks to standard Marine procedure and steers clear of needless risk no matter how others push him toward rash action. A streak of jealousy surfaces, however, whenever a peer outshines him in renown; he found it hard to accept Koby being hailed as the Marines' hero and resolved to undermine him.
Grus comes from a wealthy household in the West Blue and is 29 years old. Throughout childhood he kept his gaze fixed downward and constantly collided with walls, livestock, and passersby, so his mother gave him a long-visored cap to stop the accidents. He entered the Marines more than two years ago, training in the same recruit class as Koby and Helmeppo, and was eventually raised to rear admiral and folded into SWORD, a unit free to ignore orders from above. He commands clay through the Gunyo Gunyo no Mi, chiefly by sending out golems he controls from afar, and he also wields Observation and Armament Haki along with the speed technique Soru. During the Levely, while patrolling Dressrosa, he seized Charlotte Lola under the false belief that she was her twin Chiffon, then beat back Gotti when the Fire Tank pirate tried to free her, though Lola slipped away in the end. Later, after Koby was abducted by Marshall D. Teach, Helmeppo and Hibari begged Grus to intervene, but he held back, citing protocol and SWORD's paralysis with Drake missing. He ultimately joined Garp's strike on Hachinosu, spinning a web of clay to shield their vessel from debris while Koby shattered Pizarro's giant island hand. When Garp stayed behind to die so the rest could flee, naming them the future of the Marines, Grus was moved to tears.

The transformation everyone knows, the follow-up question nobody would touch. Why we made a smooth R&B track about the golden glow Dragon Ball never talks about....
