Iron man has like a impenetrable suit. Missiles. Guns. Bombs. Batman has skills, bat strap thing and nothing else. Easy win? Ironman picks up batman and flies into space.
You know what I thought was an easy win? Iron-man vs. Magneto from the X-men. I was like " It's obvious that Magneto is going to win. Where's the competition? " Turns out I knew who Iron-man was but, I completely misjudged Tony Stark. He beat Magneto in a way that made sense and it was convincing. Same falls for Batman. You know who Batman is but, do you understand who Bruce Wayne is? Don't count out someone because their opponent looks superior because, they just might surprise you.
Considering that Bruce Wayne and Tony Stark are genius billionaires, I gotta say that I'm a little disappointed in Bill Gates.
You guys brought up that Iron-Man have pulsar rays and he can easily take down hulk with his new designed suit but let me tell u bunch of noobs go watch Dark Knight anime, in that anime Batman beats Superman and Let u all know Superman is stronger than Hulk so yes Batman can win against Iron-Man
