The middle child and only female out of the three Russo siblings. She is sly, outgoing, and usually underachieves when it comes to regular high school. She often gets into trouble because of her constant schemes (usually involving magic). She likes to make fun of her older brother, Justin, with whom she has a really close, complex relationship and she gets along with her younger brother, Max, the two of them occasionally being shown pulling pranks together. It is implied that she is her father's favorite child and that she shares a tight bond with her mother, although they sometimes have disputes due to Alex's rebellious and disobedient personality.
