Doctor Henry "Hank" Pym is an entomologist and physicist who developed the Ant-Man Suit. For a time, he worked for S.H.I.E.L.D. as a consultant and became the first Ant-Man. Later he formed his own company, Pym Technologies and passed the title of Ant-Man down to Scott Lang.
A young promising scientist, Hank Pym was recruited by S.H.I.E.L.D. to work as a consultant. He eventually discovered a type of particles that could shorten the distance between an object's molecules, effectively reducing its size while maintaining its mass. Utilizing the newly-discovered particles, Pym developed a suit that could shrink a human being to the size of an ant, yet maintain his original strength. He also developed a device that allowed him to telepathically communicate with insects, including ants. Through concentration, he could manipulate and control insects into doing what he wished.
In 1975, a group of radicals in the Soviet-controlled East Berlin discovered a piece of an old HYDRA technology; the leaders of S.H.I.E.L.D. decided to send an agent to Berlin and stop them from reverse-engineering it. Howard Stark confronted Pym about giving S.H.I.E.L.D. his Ant-Man Suit. However, Pym was unwilling to give his suit to anyone else, so Agent Peggy Carter had to convince him to go to Berlin personally. To see if the suit actually worked, she fired a few bullets at Pym, and he became small like an ant in the blink of an eye.
In Berlin, Pym successfully snuck past the Berlin Wall only to be spotted by a guard dog. Pym managed to escape however by jumping on an anti-personnel device which then fired him to safety. He made his way into the radicals' headquarters by controlling a flying ant. He discovered that the group had not even built the device yet. He then heard screams and found a group of HYDRA scientists torturing a prisoner. Hank intervened and defeated them, liberating the prisoner in the process. Back at the S.H.I.E.L.D. Headquarters, Stark thanked Pym and told him that was his last mission but Pym refused realizing there were more problems in the world. Still only trusting himself to wear the Ant-Man suit, Pym decided to continue to do field missions.
In 1989, Pym and his partner and wife, Janet van Dyne, were called upon to intercept a Russian ICBM mid-flight. They are unable to break through the missile; this prompted Janet to disable her own suit's safety measures and shrink into subatomic size in order to penetrate the missile. Though she suceeded in disabling the missile, she was unable to halt the shrinking process and was lost in a subatomic "quantum realm" from which there is no escape.
Her loss traumatized Dr Pym, and he soon tendered his resignation to S.H.I.E.L.D. after discovering that S.H.I.E.L.D. attempted to duplicate his shrinking technology. Pym believes the technology is dangerous and vows to take the secret to his grave. He also distanced himself from his 7-year old daughter Hope and sent her away to a boarding school.
many years later in July 2015, Dr Pym returns to Pym Technologies, only to find out that Hope and his protege Darren Cross have forced him out of his own company. Furthermore, Pym is more devastated when Cross unravels his own project; an advanced shrinking suit, named the Yellowjacket, based on Pym`s original suit.
Dr Pym poses as a lawyer, and smuggles the Ant-Man Suit to Scott Lang`s cell to help him break out. Pym explains to Scott that he manipulated him through Luis into stealing the suit as a test, and wants Lang to become the new Ant-Man and steal the Yellowjacket suit from Cross, which Pym considers as an extremely dangerous equipment, literally capable of mass destruction. Scott is then trained by Van Dyne and Pym to perfectly control and manipulate the Ant-Man suit that additionally supplies superhuman strength, while teaching him to control and communicate with ants.
