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.
Gorishiro has a mind of his own, allowing him to act independently of Mizerka. He does share her enthusiasm 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.
Gorishiro shares a body with Mizerka after the latter consumed a Gorilla SMILEDevil Fruit, and so the two normally act in tandem. Gorishiro lax nature however, sometimes clashes with Mizerka's temper, example by the way he 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 possesses a notable degree of strength, being able to unleash powerful punches which can overwhelm lower-ranking members of the Beasts Pirates.
Mizerka and Gorishiro later went to the Live Floor, and the latter attacked some of their crewmates who had defected. However, Tama then ordered the Gifters she had tamed with kibi dango, which included Mizerka, to fight against Kaidou, causing Mizerka and Gorishiro to defect to her side.
