Shadow Queen Peach, from Paper Mario: The Thousand-Year Door, trained on animefull. Trigger word is squeenp
Tested at 0.85 weight, but use whatever works best for you.
Since this character is depicted differently from one piece of fanart to another, you get variations on how she looks, most of the clothing is absorbed by the trigger word, so you can either prompt it on its own along with composition/modifiers on the prompt, or mix some tags (like "super crown", "short sleeves", "purple gloves, purple cape") to try and get something different.
