Folly wears a white turtleneck sweater with light gray cuffs, black pants with realistic, red-tinted eyes printed on them, black boots, and a white beret. She also wears what is presumably a white mask with a diamond-shaped "eye", part of the mask being shattered. She also has spiky black hair and a glowing bright red left eye with yellow rings as a pupil and red lashes. Her fingertips have a bright red gradient to them. Due to Folly’s height, she looks down at the player when interacted with.  

Folly is intensely cruel, and will often fantasize about killing other NPCS or bring up traumatic events that have happened to them in her dialogue. Folly is also aligned with MR, though this alignment is implied to be less out of genuine liking for MR and more out of her needing something from it. Folly also has the ability to invade other's dreams, and uses this ability to forcefully gather information from others and feed on the fear in their minds. Due to these factors, Folly is disliked among most other NPCs because of her sadistic and mentally invasive nature. Despite this, she appears to get along with Wallter somewhat better than other characters, with them sharing poetry and classical melodies with each other.

Folly apparently dislikes the presence of the beret on her head, and usually reacts negatively when it is brought up. Due to conversations with Split and Wallter, it is implied that the beret is 'chained' to her, in The Cleave it is revealed that it is one of three 'virtues' along with her mask and sweater.

Folly turns away all attempts at compassion, refusing any items given to her. This is implied to be because of the tree falsely offering her 'true freedom' in The Cleave, which resulted in her being infected by the nightmare parasite.

She reacts in a disdained and belittling manner if players shoot at her with projectiles, but will not attack. Folly enters the elevator after completing the boss fight in the Eternal Limbo floor. Previously, she was able to enter during an elevator event where the lights would go dim and she would appear in a cloud of dark mist.

I see folly  as some sort of dark and monotone sounding  female-like character, so try to do something like that!
