Fused Zamasu

Fused Zamasu (合がっ体たいザマス Gattai Zamasu), (known as Merged Zamasu in the anime and God Zamas in the Viz manga) usually just referred to as Zamasu (ザマス Zamasu), is a Potara fusion born of the union between Goku Black (the original present Zamasu in the original present Goku's body) and Future Zamasu. He is the final antagonist of the "Future" Trunks Saga.

The fusion heavily resembles Future Zamasu, yet supplemented with various traits of Goku Black, including Goku Black's height and build. He possesses Future Zamasu's green skin, gray irises, and white hair; however, his face has more of Goku Black's jawline. He has Future Zamasu's eye shape, but with dark lines under the bottom eyelids and somewhat smaller ears. The fusion's hairstyle looks mostly like Goku Black's as Super Saiyan Rosé (Fused Zamasu himself is in the Super Saiyan Rosé form in all of his appearances in all Dragon Ball media, with the exception of his Infinite Zamasu form in the Dragon Ball Super anime), but with a long protruding bang over the right side of his face, representing Zamasu's mohawk.

He wears the original present Gowasu's green Potara earrings on both ears and Supreme Kai's clothing that is nearly identical to Future Zamasu's, but with Goku Black's color-scheme, undershirt and red sash. He also wears a Time Ring (in the anime only) on his right index finger. Retaining the arrogance and self-entitlement of Goku Black and Future Zamasu, this fusion believes himself to be the embodiment of justice. Reveling in his power, Zamasu openly declared himself the supreme god upon his emergence, repeatedly and consistently vocalizing his divine brilliance and absolute authority. His ego is displayed by how he refuses to even defend himself against Goku and Vegeta, his tendency to hover high over the battlefield to "look down" on everyone both figuratively and literally, and his use of "divine" terms (such as "holy", "judgement", and "absolution") to name his special techniques. However, beneath his calm exterior, Fused Zamasu is just as unstable as his components, if not more so; according to Gowasu, this is the result of Zamasu's obsession and hatred with the contradiction between gods and mortals. He retains his arrogance, openly gloating and overjoyed at his power.
