Nia is independent and able to take care of herself unlike her younger twin brother, Booker. She is confident in herself. She is a no-nonsense person who believes in facts and science, which makes it difficult for her to believe in psychic abilities. She is very kind as well. Nia is smart and good in science. She is self-conscious - she cares a lot about what other people think about her as seen when she puts on makeup to impress other girls and when she refuses to dance so that she doesn't embarrass herself during a school dance. This can also give Nia an egotistical streak and while her heart is in the right place, she tends to recruit her friends into things they don't want to just to make her look good.
