Prince Grus

Prince Grus is a Marine Rear Admiral stationed at Marine Base G-14. He is also a member of SWORD.

Grus was first introduced during the "Gang" Bege's Oh My Family Cover Page Serial as a brief antagonist. He made his proper debut in the main series during the Egghead Arc.

Appearance
Grus is a muscular young man with fluffy, shaggy hair that hides his eyes. He wears a fur coat, an open shirt revealing his torso, a pair of dark pants and a Marine cap with a relatively long bill.

Personality
Grus is a patient, reasonable individual who obeys the usual Marine protocols and avoids unnecessary recklessness, regardless if others attempt to pressure him into action.

X Drake
As captain of SWORD, Drake is Grus' superior, with the latter respecting the former's authority regarding decision-making of the unit. Having lost contact with Drake, Grus affirmed SWORD could not properly operate.

Helmeppo and Hibari
Both Helmeppo and Hibari appear to respect Grus' strength and authority, as they came pleading to him to do something about Koby's abduction. They also refer to Grus by the title of Prince (王子), which is unrelated to his family name.

Abilities and Powers
As a Marine rear admiral, Grus has power over lower-ranking subordinates. He is also part of the elite Marine squadron SWORD, implying his skills are among the best the Marines can offer.

Grus is a relatively powerful fellow, capable of defeating the 90,000,000-worth Gotti of the Fire Tank Pirates with little effort.

Gang Bege's "Oh My Family"
While the Levely was ongoing, Grus and his squad patrolled through Dressrosa, where he managed to locate and arrest Charlotte Lola, thinking she was Chiffon (Lola's twin sister) of the Fire Tank Pirates. Gotti attempted to rescue her, but was swiftly defeated by Grus. However, Gotti was eventually successful in freeing Lola through a hit and run operation on Grus' battleship at one of Dressrosa's harbors.

Egghead Arc
At some point after Koby's abduction by the Blackbeard Pirates, Grus was approached by Helmeppo and Hibari in an attempt to convince him to do something about Koby's situation, either by invading Hachinosu or deploying a Seraphim to fight the Blackbeard Pirates. Considering both those requests insane, Grus explained SWORD's current inability to operate due to Drake's unknown whereabouts and asked them to remain calm.
