Idk, nothing I guess. Btw, I think this music is scarier than the original.
Undermetal is my own AU, I've searched it up, and nothing related to Undertale. Either add characters to the AU, make a battle out of this, or make music for the AU. I don't expect anyone to do this, but if you're reading this, I hope you do one of the above. (Scroll to read more)-PVZGW_PRO P.S. I have a skeleTON of other things to do, so this might not be finished in time. The music is from Underswap's Omega Temmie fight: Your Tem Nightmare. I don't own Underswap, as well as Undertale. Undertale goes to Toby Fox.
