I consider myself a pretty big Avengers fan. Sure, there's a lot of holes in my team/continuity expertise, but I'd fare pretty well in any trivia challenges. One of my best NY Comic Con moments was finding the entire Under Siege story arc, where the Masters of Evil attack the Mansion. Pretty good stuff.
What I didn't know was how they got their name.
Janet van Dyne, Ant-Man's hanger-on, floozy, able to shrink down to an even more vulnerable size, maker of moon-eyes at Thor, glutton for Hank Pym's punishment, the Wasp is the one who comes up with the name:
That was...unexpected. Janet isn't taken seriously at all in the beginning, and honestly considering the crap that comes out of her mouth I don't blame them, yet there she is, at the very start of all this history, with some of the biggest heroes in the universe, and she's the one who names them, who creates the iconic, legendary franchise.
It certainly makes sense later on in Avengers history. Post-domestic-slap-abuse, Janet kinda grew up, put herself forward to be Chairwoman, and eventually became a successful team leader. Despite many marriage-related hiatuses, and temporary retirements in which she focused on her (really abysmal and talentless) fashion design career, she was one of the originals and probably clocked almost as much field time as Cap himself.
Eventually the Wasp became known for her clever strategy, leadership abilities, and her unflagging bravery. Some of these mature, solid qualities were overshadowed in Brian Michael Bendis' recent tenure on the Avengers books, returning her to a somewhat snarky and shallow dialogue and thought process, though still a warrior in her own right. Through the treachery of the Skrulls, who had posed as her ex-husband Hank, she was poisoned and turned into biochemical weapon in the final Skrull battle and despite her noble attempts, Thor was forced to really, seriously kill her. With his magic hammer.
Later, Hercules sees her in a kind of limbo realm, attempting to gamble her way back to life at a slot machine. And then Hank Pym, honoring her memory by taking up the mantle of the Wasp, cross dressing, making out with Jocasta the robot built with Janet's brain powers (but also kind of his granddaughter since she was made by Ultron who Hank created) re-formed his own team of Avengers and built something called the Avengers Infinite Mansion, which is just what it sounds like.
Where did Hank find the room for an Infinite Mansion? Why, in the Underspace of course. A realm he discovered that he suspected is where Thor sent the dying Janet, who then became a celestial entity of some kind whose eye was the perfect place to build his new headquarters.
...and also some of those outfits were just plain bad. But otherwise she's a keeper.
