Black was confused to say the least one minute he fuses with his future counterpart to become the ultimate divine being to destroy those annoying saiyans and finally achieve his perfect utopia but ultimately failing due to trunks slicing merged Zamasu in half then he sees a bright light.
Eyes open to see a black sky with a white moon in a vast grey desert.
Black struggles to get up.
"Where am I?" black says before he notices a big difference his arms and the rest of his body is covered with some white bone structure and he feels a mask over his face.
"What the fuck happened to me!"
Black ignoring his new appearance he tries to sense his counterparts ki signature but cannot find it anywhere he can't even sense trunks or goku even vegeta.
Black also notices a strange feeling on his lower back to his surprise he sees a tail his surprise is short lived though he knows the strengths and weaknesses of thee tail he did do his research before taking goku's body as his own.
"I must find a way out of this wasteland I must finish my mission."
Black tries to summon his ki to fly but he cannot.
"Damn this casing is somehow stopping me from using my ki. Is this some kind of Punishment GOWASU!!!!"
Black suddenly senses something behind him.
"oh you're a big one aren't you."
A large Meno class hollow has appeared and tries to punch black.
Black sees no reason to dodge he will show this creature not to attack its betters.
