Janet van Dyne was a shallow, self-centered, flighty heiress, daughter of wealthy scientist Vernon van Dyne. During an experiment, however, an alien monster was unleashed and Dr. van Dyne was killed. Her father's associate, Dr. Henry "Hank" Pym, had created a substance called "Pym particles", which allowed the user to grow or shrink in size, and had become the superhero Ant-Man; when Janet's father died, she convinced Pym to help her, and he gave her a supply of "Pym particles" and subjected her to a procedure which granted her the ability to, upon shrinking, grow wings and fire blasts of energy, which she called her "wasp's stings".

As Ant-Man and The Wasp, they defeated the monster and sent it to its own dimension, and had several more adventures together. Soon afterwards, the superhero team, which Janet herself dubbed the Avengers, formed, and the pair was among its founding members. Although they took occasional leaves of absence, the two have almost always remained members; during the course, Janet grew as a person and several years later would be elected leader of the team.
