Wasp

Janet Van Dyne was the daughter of world-renowned scientist Vernon Van Dyne. Early in her life, she was a flighty, self-centered dilettante living luxuriously on her father's fortune. She had an on-and-off romantic relationship with the world-renowned soldier-of-fortune called Paladin. When an alien brought to Earth during one of her father's experiments murdered the elder Van Dyne, Janet contacted his colleague, Dr. Henry Pym.

She told Pym of her resolve to bring her father's killer to justice. Pym revealed his secret identity as Ant-Man, and Janet underwent a biochemical process involving his Pym Particles that allowed her to shrink to insectoid proportions and implanted Bio-Synthetic Wings. Furthermore, Pym outfitted her with wrist devices which allowed her to discharge blasts of compressed air that she called her "wasp's stings".

Early career
As The Wasp, Jan and Hank tracked down and defeated the murderous Kosmosian, banishing it to its home dimension. Pym and Van Dyne gradually fell in love; Jan reminded Pym of his deceased first wife, Maria. Pym and Van Dyne became crime-fighting partners in their costumed identities, fighting menaces like the Egghead, the A-Chiltarians and their robot Cyclops, the trumpet-playing criminal Trago[10] and the Porcupine.They were two of the founding members of the Avengers (along with Thor, Iron Man and The Hulk) after responding when Hank's helmet picked up Rick Jones' fateful call for help. It was, in fact, the Wasp who suggested the name "Avengers" for the group that had gathered. In a further milestone in Avengers history, Jan and the other founders (minus the Hulk) were the discoverers of the great World War II hero, Captain America, still frozen from the last days of the war. Being a fashion designer, the Wasp would become known for her frequent costume changes throughout her career as a superhero.

Jan's attitude towards crime fighting was, at first, very carefree. She saw it as her way of attracting attention from Hank. Still the shallow socialite early in her career, Jan would often comment on the attractiveness of Thor to try and elicit jealousy from her partner. The studious Pym began to experiment with Pym Particles, and found that he could cause himself to grow beyond his normal height to giant sizes. Soon, both crime fighters had been exposed to the Particles long enough to be able to change size at will rather than rely on gas capsules or potions, and Jan could fire her stinger blasts without the aid of wrist devices. Changing his costumed identity to "Giant-Man", Pym eventually experienced bodily strain because of the process' physiological effects. Because of this, Pym decided to take a break from costumed adventuring. With the stress of constant threats from Pym's enemies such as Egghead, the Human Top (later Whirlwind) and the Black Knight, as well as confronting Kang the Conqueror and the Masters of Evil with the Avengers and surviving a brush with death after having been shot by a Maggia agent, Jan was ready for a break herself. Meanwhile, Thor and Iron Man also took leaves of absence from the Avengers, leaving Captain America to preside over a new incarnation of the team. Jan remained in her civilian career as a fashion designer, with Pym continuing his scientific pursuits.

Sometime later, however, Pym and Van Dyne learned that the Namor the Sub-Mariner was heading for New York City. Fearing trouble, they decided to alert the Avengers. The Wasp was captured by first Namor's foe, the undersea barbarian leader Attuma, and then by the Collector. In order to help the Avengers rescue Janet, Pym decided to use his growing power again, donning a new costume and adopting the new name of "Goliath".

Marriage and divorce
Pym had always loved Janet, but various inhibitions kept him from proposing to her - feelings of inadequacy due to her wealth chief among them. One day, while he had still not fully mentally recovered from the stress of accidentally creating one of the Avengers' greatest foes in the form of Ultron, Hank had a lab accident with experimental gases. These caused a reaction in him that broke his inhibitions down, and induced a severe case of schizophrenia. This was his second breakdown, the first having been after his first wife, Maria, had been killed. Believing he was a new person named "Yellowjacket", Pym broke into Avengers Mansion and told the team that he had killed Henry Pym When the team attacked him, he captured the Wasp and escaped. Soon after, the Avengers were shocked to hear that Janet, who suspected it was Pym all along, was going to marry him. Their wedding at Avengers Mansion was attended by a who's-who of active superheroes at the time. Immediately following, the Avengers were attacked by the villainous Circus of Crime. Janet later felt guilty at having taken advantage of Hank's mental state to finally get married, but the couple was happy... at first.
