McKinley

McKinley (マッキンリー Makkinrī) is the Captain of the White Berets (a police force in Skypeia), who tried to arrest the Straw Hat Pirates when they first arrived in Skypeia. He appears to be very devoted to Enel, until it is revealed that Enel planned to destroy Skypeia with his Devil Fruit powers. McKinley then reveals that he only did everything Enel commanded in order to ensure the safety of the citizens of Sky Island. McKinley, along with the rest of the White Berets, then leave Enel's side and choose to help Conis evacuate the Skypeian people.

Anime and Manga Differences
Originally in the manga, McKinley's initial interactions with the Straw Hats when he comes to deal with them are relatively short. Basically he fines the Straw Hats, gets hit by Nami with a waver, sends his men after the Straw Hats, and then sentences them to be judged by Enel's judges. In the anime, however, the interactions are expanded on with additional scenes. In the anime, after he fines the Straw Hats with the first two charges of trespassing into Skypiea and having the broken waver, Usopp and the rest of the Straw Hats attempt to get on his good side by doing relatively innocent and unimportant things. However, no matter what they do, McKinley repeatedly fines them with several more charges as the things they do one after another are apparently against the law. As the number of fines are increased, Nami then comes onto the scene and hits McKinley with a waver. Instead of being propelled into the bushes by the impact as was originally depicted by in the manga, McKinley is instead propelled into a wall and completely knocked out by Nami and is then escorted by his men to Conis' house where he receives some medical treatment. McKinley, however, sees through Conis and Pagaya's attempts to stall the White Berets and apprehends the two. He and his men then go back down to Angel Beach where he orders them to attack the Straw Hats. He along with most of his men however are defeated by Luffy and it is then he when is sent flying off to some bushes. From there he then proceeds to sentence the Straw Hats as he normally did in the manga.

Trivia

 * Mckinley has the unfortunate luck of being knocked into a building by someone riding a Waver that's trying to land, which becomes a running gag.
