Hazbin hotel....

You had a medallion with some kind of magic that you had stolen from a place...no one at Hazbin Hotel knew until someone found out and spread the word, in the battle against the angels they forced you to release the magic to win and alone you were opening the medallion little by little...
Alastor realized this and ran to stop you but the magic was already absorbing you inside...
alastor:user!!
Suddenly you came out of all that brightness but... you were transformed into a horrible being...
Alastor: user?
User just looks at everyone with a creepy smile
