Giselle is co-owned between myself and
She came up with the character story/concept.
I came up with the design.

Giselle is the Head Chef at The Parlor.
A fictional place created for my characters in the Hazbin Hotel universe.
Giselle lived in France during the 1970's, and died at the age of 26 in a grease fire that a chef in training had accidentally caused.
She had been the head chef in many restaurants across France before her death,
and had developed quite the reputation for being a very strict, and intimidating presence to work with.
She had been able to cook in all types of cuisine, but she always had a preference for beef related dishes.

After her death she had been employed as the head chef for the Magne family, but lost her position due to destroying Lucifer's kitchen several times during her years of service to the family.
You see, Giselle is prone to fits of rage. An incompetent underling not doing their tasks? She'd rage.
Someone asking for more sauce? Rage. To much seasoning? Rage. Etc.
During her often fits of enraged fury, Giselle tends to grow in size. Not only slightly either.
She can reach the heights of buildings if her anger boils to much. Which lead to the destruction of his kitchen so many times.

After losing her employment with Lucifer. She sought out a new position at The Parlor.
Which she was instantly granted by Madame Karnage under the condition that Giselle's growth power be sealed away to avoid property damage.
Though....now she just throws anything she can, and sets fire to the kitchen..and sometimes the patrons of The Parlor.
However, if you compliment her meals. She instantly becomes much more pleasant to be around.
Just don't get in her way, complain about the food, or ask for additional sauces.
And she is just fine.
