This article contains spoilers for the One Piece manga.

One of the many points One Piece constantly reiterates is that no organization can be taken at face value to be purely good or evil. The marines have a lot of nuance past the image they put up. While they are the greatest defense for civilians against dangerous pirates, they're also the tool the Celestial Dragons use to keep power. They keep secrets and are just as likely to order harm to a civilian populace as they are to protect it. The Buster Call is the most public means by which they cause blatant destruction. Civillians aren't supposed to know about them, but Buster Calls are well known within the marines. While Buster Calls have only been shown in three instances in the manga, they are clearly something the marines are willing to use as often as they deem necessary.

Nico Robin also has an important tie to Buster Calls. She has been involved in every instance that has been shown. Plus, all of them have also featured information about the Void Century. Ohara, Enies Lobby and Egghead Island have all been destroyed by the marines, and yet each time the Buster Call fails to fully accomplish its mission. From a narrative view point, the three original admirals have all been defined by their actions during a Buster Call. Their choices emphasize their individual morals and the type of justice they follow. Unlike the destruction of Lulusia Kingdom or even Kizarau's appearance at Sabaody, Buster Calls follows formal procedures that are known to marine personnel.
