Oimo

Oimo and Kaashii are the two giants that guard the front gate of Enies Lobby. They fight against the Franky Family, Straw Hat Pirates, and Galley-La foremen as soon as the three groups invade the island. Kaashii falls first against the combined effort of the group and Oimo is defeated when Rocketman, the prototype Sea Train, jumps the gate and crashes into him. The two are left as the protagonists press forward.

However, Usopp (still disguised as Sogeking), who had been accidentally left behind, hears them lament about their tragic existence: They had joined and worked for the Government for 50 years only because they thought that the leaders of their clan were being held captive in prison. Oimo and Kaashii were promised that by serving the World Government, their leaders would be released. Their leaders were none other than Dorry and Brogy, whom the Straw Hats had met during the Little Garden arc (This revelation was met with some concern, considering that the entire Little Garden arc was cut from the American dub). When Usopp realized this, he told the two the real truth and how he had met them.

Angered at being deceived for 50 years, Oimo and Kaashii switched sides and swore vengeance upon the World Government and Naval forces that had kept them in the dark for so long. They arrived just in time to save the Franky Family from being overwhelmed by the marines when Yokozuna gets knocked out, as well as take over it in guarding the door to the inner courthouse, keeping the marines out — But not before flinging Sogeking up to the rooftop to rejoin the Straw Hats.

After the main battle is done, they carried Sodom and Gommorah and the Franky Family out of the path of the inpending Buster Call, and manage to escape on the Puffing Tom.
