Hammer Troop

Hammer Troop (ハマー トルプ, Hamaa Torupu) are a group of Marines assembled by Vice Admiral Hammer with the expressed purpose of hunting down any pirate crew that has avoided Marine capture for over a month. In reality, their real purpose was to destroy The Marimo Pirates and kill Dhahaka D. Knave (who Hammer has a personal grudge with). They act as the main antagonists of the Hammer Saga in Grand Voyage, and are eventually disbanded.
