Human version of Cynthia Brisby from The Secret of NIMH, for my AU "Mrs. Brisby and the Bund of NIMH". Youngest and second daughter of Brisby Family, Cynthia is four years old little girl with eyes holding innocence and curiosity, also has TREMENDOUS appetite. She still has a lot to understand the concept of illness, life and death, but knows that her father won't return anymore.

Despite her limited memories of her father, she also develop greater understanding of words through reading. Among the siblings, she is nearly the most welcoming and cheerful to meet Imhumans. In fact, she is a second child to recognize the attraction between Justin and her mother Elizabeth. She is excited with an idea of having Justin as new father and possibly visiting Thorn Valley.
