Caitlin Jones is the eldest daughter of Adam Jones and Janine Walker. She has two younger siblings, a brother and a sister, and she was the first to manifest her ability out of the three. She is currently about 15 years old. She lives with her father and siblings in a house in the suburbs of New York City.
Caitlin originally looked older than her age, while she was in her early teens. She is only 5ft 7 in height. She has the characteristic dark brown eyes that are common in her family, with the dark tanned skin that's very similar to that of her Aunt Liz. Her hair is lighter than the normal nearly-black, and is merely a pretty brown. She is quite vain, and is not seen without her make-up. She showers every morning, and her taste in fashion is very up to date on the latest fashion must-haves.
Caitlin has the ability of Telekinesis, which allows her to move objects with her mind. She hid this ability at first, until she learned that other members of the family also had abilities. Before this, her aunt Liz had mimicked the ability.
