Me in FNF

Shattered form colors switches from purple to orange.

Samantha appears after Arekkusu turns back to normal and falls over, sleeping.
She thinks boyfriend beat Arekkusu up, so that leaded to a rap battle.
(Songs: Arekkusu, forget.
Shattered Arekkusu, Exorcism.
Samantha, Samantha battle. (It's actually ultra Necrozma battle, but it has a different name and Samantha battle is faster.)
(Forget by pogo.
Exorcism by Cree-p.)

I get Nightmare Sans and Shattered Dream Sans vibes from the second photo.

That's the point.
