Rosie/History

Past
Not much is known about Rosie aside from the fact that she is an Overlord and is one of the most powerful demons in Hell.

However, from what is seen in the pilot it seems that she owns an emporium.

Hazbin Hotel pilot
In the opening of the pilot, Rosie is seen crossing out the name "Franklin" from the emporium's sign since Franklin more than likely perished from the extermination and was subsequently eaten by Rosie's minions afterward.
