Chat was created by author Paul Tobin as an original girlfriend for the Spider-Man appearing in his Marvel Adventures Spider-Man comic book. She first appeared in Marvel Adventures Spider-Man #53 and appeared in every subsequent issue until the series was canceled with #61. Chat next appeared in Tobin's Spider-Man Marvel Adventures comic-book series, which continue the stories started in Marvel Adventures Spider-Man. These stories feature a teenage Peter Parker/Spider-Man with a supporting cast of revamped Marvel Comics characters, as well as all-new characters such as Chat. Chat was introduced into the mainstream Marvel universe in the 2011 series Spider-Girl #4 as a friend of Anya Corazon's new roommate. It is unknown if she is a mutant or a normal human in this reality.
Little is known about Chat's childhood except that she was raised by an unknown mother and has an older sister. She is secretive about her mother and admits she hasn't talked about her for a couple years. A young mutant, Chat has the power to communicate with animals, an ability that also makes animals act unusually friendly around her. Although this aspect of her power embarrassed her, Chat used her animal affinity to help run a traveling zoo that visited all the New York orphanages. At some point, Chat felt herself "falling apart" and tried to re-establish her life. Becoming a runaway, she met Emma Frost, a teenage mutant with the ability to read and control minds. Self-absorbed and immoral, Emma regularly used her powers to rob stores and learn intimate secrets by peeking into people's minds. Although Chat disapproved of Emma's actions and often tried to stop her, she was too timid to truly stand up to Emma. This began to change when Chat and Emma were saved from a falling sign by Peter Parker, a teenager who was secretly the adventurous superhero known as Spider-Man. When Emma, using her telepathy, discovered Peter's secret, she convinced Chat they could "have some fun" by going to Peter's high school and learning more about his other identity. Through to a mind-link set up by Emma, Chat discovered how Peter became Spider-Man and was profoundly affected by his sense of responsibility, which she found both noble and attractive. Convincing Emma to help her enroll at Peter's school, Chat began dating Peter and would often use her powers secretly to help Spider-Man. Chat eventually told Peter about her mutant powers, and that she knew of his Spider-Man identity. She also joined the Blonde Phantom's detective agency, a firm that employs superhumans, and was even asked to join the X-Men, although she declined. Her relationship with Peter, along with the self-defense training she has received from the Blonde Phantom, has made Chat a much more confident and assertive person and she continues to support Peter in his duties as Spider-Man.
Powers and abilities
Chat is a mutant with the power to communicate with animals, although whether this ability is based on an understanding of animal verbal/non-verbal communication or a form of telepathy is not yet known. Animals sense that Chat can understand them and become very friendly around her. Even when an animal is normally aggressive, Chat can gain that animal's loyalty. Chat often uses this power to calm down nervous and wounded animals at animal rescue centers. Her natural affinity with animals, along with Chat's tendency to feed any stray who visits her, makes animals very accommodating when Chat asks them to do favors for her. In the past, Chat has asked pigeons to eavesdrop on conversations and trail people for long distances. She has convinced birds and dogs to attack criminals, and once mobilized a group of squirrels to steal letters from a mansion. Even when Chat is not around to tell animals what to do, animals who have been around her will continue to act in her interests, usually by protecting her friends. Thus, many stray dogs, cats, and birds in New York now protect Spider-Man..
