A horror + Bad End AU Fawful that nobody asked for, introducing the Fawfulomaniac AU, aka Goggles! Fawful.
No longer satiated by kingdom conquering, this Fawful was successful in absorbing all of the dark star uninterrupted. Unfortunately he was beaten by the bros but the excess power allowed him to escape and bide his time underground. He had rebuilt his strength but the influence from the Dark Star's power changed his body and mind. After successfully taking over many-a kingdom he discovered that it wasn't enough. He became hungry for power and destruction. Letting god syndrome take the wheel he ended his own world and traverses to others to torment.
Enjoy the food cuz you're probably gonna see this guy like a grand total of 2 times. Maybe during Halloween as a treat.
