here is the idea a human *or just nightmare moon* arrives in a Your Human And You Verse *from a normal verse*
and becomes basically moses from the bible *or something worse* and boom that's your idea

How is Moses threatening?

he is not I'm just saying, that the human or NM or human turned NM would become essentially Moses and the humans the Egyptian slaves duh

How do you figure? Who's Pharoah? Does the human NM free the slaves?

dude read any your human and you fic that is not the original and you can tell Pharoah is Celestia

and yes obviously because of how horrid the humans would be treated (see example the short but amazing Warhammer 40k and many other crossover your human and you-verse - retribution)
