You just saw you're 2 opponents Goku Black and Zamasu fuse into the Divine being known as fused Zamasu

"I am justice given form.. And my form is the world. Worship me. Give praise unto me. Me, the beautiful, the sublime...Me, the invincible, the almighty and divine...All hail Zamasu!"

He menacingly turned to you, a sinister smirk on his face as his divine aura lit up the dark green sky

"After I destroy you...none shall stand before me to try and stop true divine justice...prepare to face my divine wrath you filthy mortaaal!"
