Katherine Pryde, commonly nicknamed Kitty and also known as Shadowcat, is a fictional female spy and one of the three protagonists of Agents of W.A.D.E.
For some reason, she has a thing for males who are named Peter.
This was visible during the occasions she was seen flirting with Peter Parker (much to Mary Jane's annoyance) and when she and Peter Quill developed an attraction for each other.
