Look up Bowletta. They're an official character from Mario and Luigi Superstar Saga and are the closest we'll probably ever get to an official 'Bowsette' type character, though more on the horiffic monster side of things.
Helps to portray her evil side. Maybe using Harley-Quinn as a bit of inspiration; axe instead of a mallet
What’s more interesting about this thing is she is seen to be having axe attached to her right hand
I wonder what her lore is going to be like if she doesn’t get scraped and ended up making it into the final game…
