Hot Wind Marines

The Hot Wind Marines (熱血特別部隊) are a Marines unit who appeared in the anime only G8 arc, and made their debut in Episode 201. They are a group of powerful Marine soldiers, who practice in G-8 by fighting and singing according to the "Wind of their souls".

History
They tried to stop Luffy, Zoro, Usopp and Sanji at the G-8 base while the pirate crew tried to escape. They were easily defeated. Their main objective was to stall for time, so that Vice Admiral Jonathan could get to the Going Merry before they did, in order to ambush them. However the ambush failed.

Trivia

 * Their singing is similar to the "Duckworth Chant" which is a famous military cadence.
