Rare Henry W tbh.
Rilliane Lucifen D'autriche from Evillous Chronicles- While technically a queen, Rilliane refuses the title of queen after her mother's death out of respect, so she still fits this trope. Imagine Marie Antionette but amped up to 11 and that's essentially Rilliane, she's tyrannical, she's flagrant with her spending, she enjoys displays of power over others, at one point she even orders an entire country to be ransacked out of jealousy.
Princess Azula from Avatar The Last Airbender- Azula is basically the perfect example of this trope. She's spiteful, ruthless, blood hungry, and utterly bat shit crazy. She very much embraces the fact her father "loves" her more than zuko and has no issue trying to kill the avatar to make him proud. She never really got the chance to be a normal teenager, even compared to other kids in the avatar universe, and thus she has the mind of a blood hungry war general and acts as such.
Mary 1st of England from real life- She was literally nicknamed bloody mary for burning so many protestants at the stake in an attempt to restore catholicism to England and even imprisoned her own sister, Elizabeth because she suspected she was plotting with protestants. She was a complicated lady, and she had her fair share of problems (miscarriage, parents divorced, ect.) but it's hard to not call someone one evil for killing over 200 people over differing beliefs.
I brought up stephen king to him cause he told me his fav author is mo willems so i told him mine was stephen king, and when he asked who that was i pulled up a picture of him. It was a pretty normal photo of him, just him kinda staring off into space lookin old as fuck. He then proceeded to turn his whole body away from me and huddle into a ball and whine "i don't like himmmmm".
Honestly i get it. I always say the scariest part of any king book is the author portrait on the back.
