How Batman Would Defeat Each Member Of The Avengers
6. Wasp
When talking about Ant-Man, particularly in regards to being a founding Avenger, it's impossible not to talk about Wasp.
Like Hank Pym, Janet van Dyne is another who founded Earth's Mightiest Heroes, and similarly she has the ability to shrink in size. Granted, Wasp does have the ability to fly and to project energy blasts, but those additional powers wouldn't cause Batman all that much grief.
For a Batman vs. Wasp fight, the Dark Knight would very much pull on the same plan of attack that would be used on Ant-Man. Janet has no way to get under Batman's skin due to how solidly built and protected the Batsuit is, and the small stature that Wasp has so often used to her advantage wouldn't be a problem for Batman - with him able to track her and keep a constant monitor on her whereabouts.
When it comes to any attacks Wasp launches his way, Batman has proven time and time again that his reflexes and dodging ability is enough to outmanoeuvre some of the most powerful beings in the galaxy. Throw in how the Caped Crusader has used his grappling gun to evade otherworldly beasts, such as Doomsday, then he would stand a fine chance of avoiding any of Wasp's attacks - to the point where Bats could edge in closer to Janet, which would then be game over for her.
Should Wasp foolishly decide to go toe-to-toe with Batman, that would obviously end in utter failure. Not only has Bruce got the physical advantage and exceedingly better fighting skills, even the skills that make van Dyne so unique would be rendered useless by the technology that the World's Greatest Detective has to his name.
