Gorishiro

Gorishiro is a gorilla that is attached to Mizerka's body due to her consumption of a gorilla SMILE.

Appearance
Gorishiro is a standard gorilla from the legs up, growing from Mizerka's hips. Mizerka upper body comes out from his abdomen, with her arms still inside Gorishiro. He also wears a dotted belt with a minimalistic Jolly Roger of the Beasts Pirates, and a stripped set of headphones.

Personality
Gorishiro has a mind of his own, allowing him to act independently of Mizerka. He does share her entuthiasm during the Golden Kagura, and where Queen declared a way for Mizerka to became a Tobiroppo. He seems to behave very much like a stereotypical gorilla would, having a preference for bananas and being a messy eater.

Mizerka
Gorishiro shares a body with Mizerka after the latter consumed a Gorilla SMILE Devil Fruit, and so the two normally act in tandem. Gorishiro lax nature however, sometimes clashes with Mizerka's temper, example by the way he was messily ate a banana while the Beasts Pirates were preparing to ambush Luffy.

Abilities and Powers
Though he is limited by only going where Mizerka goes, Gorishiro was ready to fight Luffy and Zoro at a moments notice, showing he is a capable fighter. Gorishiro's full abilities and Mizerka's application of it in combat have yet to be seen.

Wano Country Arc
On the day of the Fire Festival, Gorishiro was seen with Mizerka taking part in Queen's Golden Kagura festivities. When the Ninja-Pirate-Mink-Samurai Alliance later invaded Onigashima, Mizerka, other Gifters, and Scratchmen Apoo stood in Luffy and Zoro's way. After the Alliance invaded the tower, Mizerka and Poker were stationed on the third level at the base of the stairs to the fourth level, where Gorishiro ate a banana above Mizerka head and drop crumbs on her head, annoying her.

Trivia

 * "Gori" is likely a reference to him being a gorilla, while "shiro" is a male name suffix used for the fourth son of a family.
