Janet van Dyne is the wife of Hank Pym and the mother of Hope van Dyne. She operated as the superhero Wasp in S.H.I.E.L.D. until she sacrificed herself to save the lives of millions, becoming lost to the Quantum Realm.
Real Name: Janet van Dyne
Portrayed by: Michelle Pfeiffer
Janet van Dyne married Hank Pym, a scientist who developed a way to shrink a human to the size of an ant and maintain their strength. He also discovered a way to communicate with ants. Together they had a daughter named Hope.
Janet van Dyne convinced her husband Hank Pym to let her join his missions for S.H.I.E.L.D.. With her own shrinking suit, she became known as the Wasp alongside Hank as the Ant-Man.
The duo undertook many S.H.I.E.L.D. operations, until a mission in 1987 to disarm a Soviet ICBM en-route to the United States. In order to stop the missile, Janet disabled her regulator to shrink small enough to enter the missile and though the mission was successful, Janet was lost to the Quantum Realm.
To protect their daughter, Hope, from the horrifying truth, Hank told her that Janet had died in a plane crash. He finally told her the truth in 2015. Seeing that Scott Lang survived and returned from the Quantum Realm after a showdown with Darren Cross, Pym wondered if his wife was still alive as well.

After Scott Lang entered the Quantum Realm, van Dyne was able to send a message to him, causing him to notify her family. They then began working on a way to retrieve her from the Quantum Realm, something Pym had been desperately trying to do for some time, having been given hope that she was alive. Their ambitions succeeded, and she was freed from the Quantum Realm as an evolved human with superhuman powers, and she temporarily healed Ghost after reuniting with her family.

Van Dyne then worked with her family to send Lang into the Quantum Realm in order to fully heal Ghost. However, when Thanos snapped his fingers to erase half of all life in the universe, van Dyne, alongside her family were among those who died, leaving Lang trapped in the Quantum Realm.
Fortunately, she was resurrected in 2023 along with every other individual who had been eliminated during the Snap, and later attended Tony Stark's funeral.
