Beatrice is (seemingly) the main antagonist of the first half of the anime and visual novel Umineko no Naku Koro ni.
Beatrice appears very sadistic and seems to think of things as a game. She is also manipulative as she almost tricked Battler into believing she had redeemed and thus making him sign a contract proving his belief in her existence. However, she and Virgilia cracked there and Beatrice showed her kind and gentle personality had been an act. She doesn't seem to be easily insulted, as when she had given away a witchlike laughter. Her butler commented her "laugh lacks elegance'", to which she replied "Oh, I'm sorry" and gave away a more controlled chuckle.
Her goal is to make Battler accept and acknowledge her existence.
Beatrice has blonde hair in a neat bun with a red rose at the side of her head. Her eyes are bright blue.
She wears a dark violet choker with a lace hem, matching the collar of her dress. The dress is very elaborate, dark violet with golden markings that resembles fire.
Beatrice's symbol are golden butterflies; she is also the Golden Witch.

In the anime, Beatrice is defeated by Battler when he manages to explain her last scenario with human tricks. She is impaled by large, sharp rocks growing from the earth. In the end, she begs Battler to "just... Help me die..."
In the visual novel's sequel Umineko No Naku Koro Ni Chiru, depending if you chose the magic ending, her and Battler attempt to leave Rokkenjima and Beatrice suddenly disappears into the ocean, as she and battler sink down in the ocean and fade into nothingness.
- Beatrice is often depicted as a troll due to her sadistic nature, to the point of being called "Beatroll".
- Beatrice's original name is uncertain, given Virgilia's former name was Beatrice as well and the name was passed down to Beatrice along with the title of Endless Witch. *When Beatrice was young, Virgilia called her Princess, though it is unconfirmed if that was a title or a nickname. When Beatrice passes her name and titles to Eva-*Beatrice, Battler continues to call to her as "Beato", the nickname that both he and Maria previously refered to her as, when she demands that he give her a new name.
- Her nickname "Beato" is actually Italian male name and it can be translated as "blessed".
- Beatrice's name is pronounced the Italian way, as "Be-a-tri-ce" (Be-a-to-ri-che [ベアトリーチェ] in Japanese phonetics) rather than the English way, as "Be-a-triss".
- Beatrice, out of eight characters, has had two portraits of her featured in it.
- The embodiment of Beatrice as Battler's ideal woman is most likely a reference from La Divina Commedia in which Beatrice Potinari is also Dante's ideal woman.
