Beatrix

Beatrix is a young Ever at the School for Good. At first, she was known as the "best" Evergirl at the School for Good, also as one of the most eligible princesses, and a large number of Everboys competed for her attention.

Appearance
In the first book, she is described as the fairest of them all, blond, much more radiant that she sun itself and was considered as the most beautiful Evergirl. Her golden blond hair fell to her waist, she has topaz eyes and succulent lips, and she was "tall and ravishing".

In the second book, as part of the Debeautification process in the School for Girls, Beatrix gives up on her appearance, deciding to shave off all her hair, becoming bald. Later on, she admits that she misses her hair (possibly regrets shaving it off), and keeps hair extensions and other beauty supplies inside a trunk that can be found under her bed.

Personality
Beatrix might come off a stereotypical mean girl who falls in love with the most popular guy at school (Tedros) as a first impression. Supposedly, she's the "ideal princess"- beautiful, kind, loving and anything else that falls under that category. And, like most Evergirls, she puts looks above anything else.

She, among many other characters, had some character growth as the second installment of the trilogy came out. She becomes much more friendly and selfless, yet, like the Beatrix we read about in the first book, she despised men.

In the School for New Evil, she had matured more, and played a somewhat great part in the fight against the School Master.

Sophie of Woods Beyond and Agatha of Woods Beyond
She acted quite nice to Agatha for a while, but didn't really take much of a liking to her. She was upset when she found out that Tedros was interested in Agatha.

She never really liked Sophie, being her "rival" for Tedros' heart. She never really liked either girl and continually called Agatha offensive things, and humiliating Sophie in front of Tedros. Neither girls liked her either, which didn't change until the events at the School for Girls where in she praises them for freeing princesses from princes, girls from boys, women from men.

Neither Agatha nor Sophie like her much, which doesn't change in their second year at the new School for Girls. In The School for Good and Evil, Beatrix is very mean to both Sophie and Agatha, often calling Agatha offensive names and repeatedly humiliating Sophie in front of Tedros. At the School for Girls, however, she praises the two Readers for freeing girls from princes, openly admiring them.

Tedros of Camelot
In the first installment, she constantly flirts and is clingy with Tedros, believing that they are perfect for each other because she is "the most sought-after Evergirl" while he is "the most sought-after Everboy". Albeit her insistent advances, Tedros does not show much interest in her nor does he care much about her and what she does. Despite his dislike of her, he humors her a multitude of times, initially believing that both Sophie and Agatha are witches.

After the Tedros-Sophie break up, she assumes he would want to be with her instead, only to be disappointed at his sulking over Sophie's betrayal and finding an interest in Agatha.

Millicent and Reena
Beatrix is shown to constantly be around a group of about 7 Evergirls, but those closest to her among them are Millicent and her roommate, Reena.
