History: Pym was a brilliant scientist who spent much of his time in his lab. At one point, he met and married the beautiful Maria Travonoya, a political dissidant who had fled to the US. Unfortunately, when honeymooning in her home country of Bratislavia, she was captured by revolutionaries, and, despite Pym's efforts, she was killed. Pym had a nervous breakdown and spent some time in a Bratislavian mental hospital until he was freed by American officials. He became obsessed with bringing his wife's murderers to justice and the creation of his subatomic Pym particles was the result. He found himself shrunk to a fraction of an inch and had to escape from an ant hill. He destroyed his creation after his first adventure for the danger they posed but later recreated them, fashioned a costume that included a cybernetic insect control helmet and began to adventure as the hero Ant-Man. The villain Egghead was his first archenemy. In the meantime, he was contacted by the father of Janet Van Dyne to help Van Dyne in his scientific experiments, and he soon fell in love with Janet, who reminded him of a young Maria. When her father was killed by the aliens he was trying to contact (it would later be revealed that these aliens originate in the dimension of Kosmos, the matter exchange dimension for all size-shifters), Pym as Ant-Man brought the Kosmosian to justice. Ant-Man revealed his identity to Janet, and Pym convinced her to join him as his partner. He engineered her body to become his sidekick as the hero Wasp. Ant-Man and the Wasp were on hand to battle the monster Hulk with heroes Thor and Iron Man, when the Wasp suggested they form a team, the Avengers. About the same time, he created the robot Ultron-1,who brainwashed Pym into forgetting this acheivement, revealing itself many months later as his enemy. Pym continued to fight alongside the Avengers, but soon felt outclassed by the powerhouses of the team and created the identity of Giant-Man. Later still, Wasp, fearing for Pym's health, prompted the duo to leave the team. Pym found himself back in the Avengers when Wasp was abducted by the Collector, creating another identity of Goliath. Although he usually preferred to abstain from adventuring to stay in his lab, he continued to fight off-and-on alongside the Avengers because the Wasp always wanted to. Years later, Pym, who was undergoing severe mental stress, had an accident in his labratory, breathing in chemical fumes. His sanity warped, and created a fourth identity who believed he had slain Pym: Yellowjacket. He returned to the Avengers, kidnapped Janet and forced her to marry him. When he was confronted by the Avengers and brought back to his right mind, Pym and Janet decided to let the marriage stand. They adventured with the Avengers, and later, they enjoyed a brief tenure alongside the heroes of the Defenders. Pym's mental problems continued to worsen. He returned to the Avengers, determined to prove himself alongside the heavyweights of the team, which only added to his stress. At one point, he struck Janet, and later, during battle with the misguided Elfqueen, Pym lashed out at her just as she was about to surrender. The Avengers began a court-martial process for Pym, who, losing his sanity, created a robot to destroy the Avengers but built with a failsafe that Pym would activate to "save" his friends and regain his status. The ploy failed, and the Wasp, who discovered Pym's treachery, saved the team. Pym promptly quit, and the Wasp filed for divorce. Pym was further oppressed as his old enemy Egghead framed Pym for stealing nuclear devices, leading to Pym's arrest. Egghead led the villain team Masters of Evil in freeing Pym from his trial, further implicating him in villainy. Pym soon defeated the Masters singlehandedly, redeeming himself, but he decided against rejoining the Avengers. Pym later would ally with them when his expertise was needed. Over time, his relationship with the Wasp was reconciled. Later still, Pym found his body could not handle the stress of constant size-changing, and retired from costumed crime fighting. He still joined the Avengers, however, when they opened their West Coast branch, in order to oversee the facilities and the scientific research. Growing more despondant as a result of the Whirlwind's prodding, however, he soon decided to commit suicide, but was stopped by their associate Firebird (then Espirita) who helped him to reconcile the two areas of his life--costumed crime fighting and scientific research. As Hank Pym, Scientific Adventurer, he would use the aura of Pym Particles his body produced to to shrink and grow objects around him, and he rejoined the Avengers full time. Although he stayed with the West Coast branch for some time, Pym soon found himself actively adventuring from the New York mansion. Later still, Pym and other size-changing heroes were caught up in an invasion attempt from their mass-displacement dimension, Kosmos. The outcome left Pym able to grow again but not to shrink, and he resumed his old Giant-Man identity. Continuing to adventure alongside the Avengers, his relationship with the Wasp steadily improved, becoming very platonic romantically. Their relationship hit a rough spot during the battle with the time-traveling villain Kang (in actuality, Kang's rival Immortus posing as Kang) when, in order to save the Wasp's life, Pym performed radical life-saving experiments which transformed her into a bug-woman hybrid. Pym was on hand with the other Avengers who seemingly sacrificed their lives to absorb the energies of the being known as Onslaught. In reality, he was shunted to another dimension. When he and the other heroes were restored to Earth, Pym found that he was capable of his full range of size-changing abilities, but rather than return to the Avengers right away he returned to his research.
