Chessmarimo

Chessmarimo is a fusion of Chess and Kuromarimo, created by Wapol's Baku Baku Factory. Sanji comments that Kuromarimo is simply standing on Chess' shoulders and only their clothes were fused. Oda, however, treats Chessmarimo like it is one entity. They become a stronger warrior with 4 arms, 2 heads (Kuromarimo's above Chess'), and many weapons which allow them to use their powers to the full extent, such as arrows, hammers, and axes. He was defeated by Chopper using his Rumble Ball scope. His weakness, according to the scope, is the section under Chess' chin. He was defeated by Chopper's Kokutei Roseo. It is unknown what happened to him after Chopper defeated him.
