Brilliant but unstable biochemist and robotics engineer Henry Pym never really intended to become a Super Hero. When a group of spies captured his assistants, he was forced to use his inventions to save them. That is when he discovered his true calling. Since that day, he has been one of America's foremost heroes, adventuring with various groups of AVENGERS. Though he has suffered many tragedies over the years, he has never stopped trying to be the best hero he can be.
