When Goku Black merged with Future Zamasu with the Potara earrings while in the Super Saiyan Rosé form to become Fused Zamasu, and later (in the manga) transitions into Infinite Zamasu, the result is a being who is constantly and permanently in the Super Saiyan Rosé form, due to fusions created with Potara Earrings automatically assuming the transformed state(s) the fusees were in at the time of the merger, and the resulting fusion being unable to power down from that form. In a close up of Goku Black, his hair looks spikier, however, this is the case for all characters who are zoomed in on, as a result, some have mistakenly stated that the hair spikes up and changes more than it actually does. The aura is more jagged and flame-like than the aura of Super Saiyan Blue. In the manga, the form is differentiated from Super Saiyan Blue in the same way as the anime. Usage of this form also appears to greatly augment Black's techniques, including his Super Black Kamehameha and his signature Violent Fierce God Slicer, allowing him to extend it into various more elaborate shapes his other techniques also change their usual appearance to match the form's coloration.
The aura is a very dark shade of red on the outside, but transitions into a more pinkish color on the inside while the aura is present, Black's clothing becomes brighter, while his eyes appear as pink and the color of his hair and eyebrows become a slightly darker shade of pink (due to him being illuminated by the aura) and he acquires a dark purple glow around his body. In the anime, this state is identical to the first Super Saiyan form as well as Super Saiyan Blue in all but color: Black's hair takes on a pastel pink color with faint white highlights, with his eyebrows matching the color of his hair, and his eyes change to light gray. Super Saiyan Rosé possesses a darker equivalent to the aura of Super Saiyan Blue Goku confused about the transformation's appearance in " The Zero Mortal Project".
