As founding members of the Avengers, the husband and wife team of Ant-Man (Hank Pym) and the Wasp (Janet van Dyne) are two of the underappreciated pillars at Marvel. They were there at the dawn of the company’s renaissance, and they have had a consistent presence for about 50 years. Hank in particular has had an immeasurable impact on the Avengers over the years as his split personalities and creation of Ultron have caused Earth’s Mightiest Heroes more indigestion than eating a dozen day old fast food enchiladas.
But despite their problems, this romantic duo has always had one of the more entertaining dynamics at the company. One minute they're at each other’s throats, and the next they’re locked in a loving embrace. And it’s that type of lovable disharmony that has become a trademark of Lee and Kirby over the years.
