Who is a fictional character with histrionic personality disorder?

Another example might be Norman Bates from 'Psycho'. His intense fear and suspicion of the outside world, along with his strange behavior, could suggest a paranoid personality disorder.

In the TV series 'Skins', Effy Stonem is sometimes portrayed as having borderline personality disorder. Her emotional instability and impulsive actions are some of the indicators.

One such character could be Regina George from the movie 'Mean Girls'. She shows extreme self-obsession and a sense of entitlement.

Sure. There was a woman, let's call her Lisa. She always needed to be the center of attention. At work, she would constantly interrupt meetings to tell dramatic stories about her personal life, even when they were not relevant. She dressed in overly flashy and revealing clothes just to draw people's eyes. When others didn't give her the attention she craved, she would throw tantrums or start crying, making others feel uncomfortable and pressured to attend to her.

In a real story, one common symptom is excessive attention - seeking. Just like the person who always tries to be the center of every conversation, no matter what the topic is. Another is overly dramatic behavior, such as overreacting to minor things. For example, crying uncontrollably over a small mistake.

Well, there's Regina George from 'Mean Girls'. She's constantly seeking attention, believing she's superior to others and has a sense of entitlement.

One example could be Severus Snape from the Harry Potter series. His behavior often shows signs of passive aggression, especially towards Harry and his friends.

Hannibal Lecter from 'The Silence of the Lambs' is another. He's manipulative, has no remorse for his actions, and shows little regard for the rights of others, which are common signs of this disorder.

Well, 'histrionic fictional' isn't a common phrase. Maybe it refers to fictional works that are overly dramatic or theatrical.

I don't think so. Loving a fictional character is just a form of escapism or a way to express one's imagination. It doesn't mean there's a disorder.
