This is "Always Kind of Wondered," a feature spotlighting instances from comics where a comic book writer has clearly said, "Hey, why doesn't Character X ever do Action Y?" The sort of things that typically occur when comic book fans grow up to become comic book writers, which wasn't really a thing until the mid-1960s.
Today, we look at how Ant-Man learned how to grow, but it took ages before it occurred to anyone to have the Wasp grow, as well.
In Tales to Astonish #44, Jack Kirby and Stan Lee added a new partner in crimefighting for Hank Pym (Ant-Man) in Janet Van Dyne, the Wasp....
Five issues later, though, in Tales to Astonish #49 (by Kirby, Lee and Don Heck), Hank used the growth capsules that they used to go from their tiny sizes to normal size to take him from normal size to GIANT-size...
But what about Hulk?
About a decade later, in Marvel Premiere #6 (by Mike Friedrich, Herb Trimpe and Mike Trimpe), Hank was trapped in his shrunken size and he tried to come up with an antidote working with Jan. She tried it out on herself and she shot up in size to the point where she knocked herself out...
Years later, in the Giant-Man miniseries by George Perez, Jerome Moore and Tim Dzon, anyone who had ever grown on Earth started going haywire, including Jan...
However, it really wasn't until Avengers #77 (by Chuck Austen, Olivier Coipel and Andy Lanning) that Jan finally truly used her growth powers...
A few issues later, she noted that she was still getting the hang of the new powers...
Still, someone finally decided to have Wasp grow the same as Hank, which is really something that you would have thought that another writer would have come up with at some other point in the history of the Wasp. Obviously, these new powers went poorly for her later when she essentially died during Secret Invasion as part of her growth abilities (which is likely why she hasn't really used the powers since then).
