Chimpy

Chimpy is the main character of the spinoff manga Chin Piece.

Appearance
Chimpy is a young boy who greatly resembles Monkey D. Luffy, wearing a tattered open vest and shorts held together by a rope. He also wears a sleeping tanuki on his head to resemble Luffy's straw hat.

Personality
Chimpy seems to be very bold and brash, having no issues with displaying his stretching penis in front of people he just met.

Abilities and Powers
Chimpy has the ability to stretch his penis, attempting to emulate Luffy's stretchiness. He can stretch his penis to great lengths and manipulate its shape, allowing him to wrap it around objects. His penis is strong and can lift weights as well as hang on tree branches.

Techniques

 * Chin Chin no Chinko Pistol (チンチンのチンコ・): Chimpy stretches his penis forward with great force, similarly to Luffy's Gomu Gomu no Pistol technique. He first did it for show in front of some kids in town.
 * Gomu Gomu no Poop (ゴムゴムのウンコ): After eating gummies, Chimpy can shoot out a long strip of poop, similar to the Chin Chin no Chinko Pistol; unlike the pistol, however, the poop will follow its target until it hits.
 * Rubber Poop Dragon Tornado Hold (ゴムウンコ・トルネード・ドラゴン・ホールド): Upon the poop reaching its target, it will wrap around them, essentially locking them into place.

Past
Chimpy looks up strongly to Luffy, and tried to train his body to stretch as well; however, he realized that the only stretchy part of a human is their penis. He then began working on strengthening his penis, increasing its power and capabilities.

Chin Piece
Chimpy came to a village, where he met a group of kids led by Kusopp. There, he demonstrated his powers in front of them.
