Science Adventurer. Biology Guy. Moral Compass.
Scientist Hank Pym is one of the smartest men on the planet, specializing in biochemistry. He is a man of science, and never intended to become a Super Hero, but adventure tends to find him. Outfitted with this cybernetic helmet, the microbiologist Hank Pym can communicate with insects and shrink himself to microscopic scale as Ant-Man.
When tiny, he still packs the punch of a full size man, but he can also use his power over matter to grow 20 feet tall as Giant-Man. Which means he's a good friend to have in a fight, and is a fearsome part of...THE AVENGERS!
