Abilities and Powers
They are a group of powerful Marine soldiers, who practice in G-8 by fighting and singing according to the "Wind of their souls". However, they were easily defeated by the Straw Hat Pirates.

G-8 Arc
They tried to stop Luffy, Zoro, Usopp, and Sanji at the G-8 base while the Straw Hat Pirates tried to escape, but 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 due to Luffy destroying the bridge they were on.

Trivia

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