This character is in S02E06 and S03E01. Dot Beatty-Simon is a brilliant but mentally ill young woman who is infatuated with Doctor Calculus. She is the inventor of his suit and the co-inventor of its power source. She is hypersexualized and at the same time a bit childish and childlike. Like Doctor Calculus, she was a child prodigy. She met him in college when they were both too young to handle the emotions and hormonal urges they were feeling. They had a tumultuous relationship. Her physical maturing brought on both the development of her superpowers and the onset of her dissociative identity disorder, both pivoting on their break up.

She hints at abuse in her family by her father toward both her mother and her. This is not corroborated by her mother or her father, but may very well be the truth. She experiences life like someone thrown in a pool and told to swim, only she has a weight strapped to her ankle.
