Supemran's narrative state is "invincible"
goku's narrative state is "I don't care that it's literally impossible for me to beat you because you're invincible, I'm gonna do it anyway!"
Goku's narrative would take precedent over Superman's simply because Superman's narrative role is shared by the antagonists in goku's stories.
Also, Hakai. Superman doesn't have a defense against godly magic what completely obliterates both body and soul.
