Fullbody

"Double Ironfist" Fullbody is a Marine lieutenant commander serving under Rear Admiral Hina. He was a Marine Headquarters lieutenant at the start of the series, but was demoted to seaman recruit as a condition when he helped the former Black Cat pirate, Jango, get acquitted for his past crimes (in the anime, it was after getting into a fight with Sanji on the Baratie). During the timeskip, however, he rose back through the ranks to become a commissioned officer once again, being one rank higher than he was to begin with in the series.
