Ant Man + Ants
Dr. Henry Pym, an American biochemist with extensive knowledge in other scientific fields, married Maria Trovaya, a brave and beautiful young woman who had been a political dissident in her native Hungary, from which she had fled. Naively believing that his American citizenship would protect her, Henry and Maria Pym traveled to Hungary shortly after their marriage. The Pyms were confronted by agents of the secret police there. Henry Pym was knocked unconscious and Maria was murdered. Pym was greatly distraught by his wife's death, and decided to do whatever he could in the future to battle injustice and inhumanity.
Back in the United States, Pym discovered a rare group of subatomic particles, which have become known as the "Pym Particles." Pym was able, through the application of magnetic fields, to entrap the particles within two separate serums. One serum would reduce the size of persons and objects, and the other would restore them to their normal size. Pym tested the reducing serum on himself and discovered it was more powerful than he had expected: it reduced him to the size of an insect. Pym became entrapped in an anthill and was pursued by the ants within. He escaped and restored himself to his normal size with his other serum. Deciding that the serums were too dangerous to exist, Pym destroyed both of them.

However, weeks later he reconsidered his decision and began to recreate the serums, whose existence he then kept secret. Inspired by his experience in the anthill, Pym undertook a study of ants, and theorized that ants communicate through psionic / electrical waves transmitted through their antennae. After months of work, Pym succeeded in creating his first "cybernetic helmet," which would enable him to communicate with ants through transmitting and receiving psionic / electrical waves. Thinking that someday he might want to use the shrinking potion on himself again, Pym also designed a protective costume for himself, Unstable Molecules and steel mesh.
