Batman is a great superhero but he lacks certain skills that are necessary to be able to be a very successful hero. Firstly, he cannot fly and does not have any superpowers...he cannot throw missiles at a top speed. Secondly, Batman is much easier to defeat than Iron Man because of the suit differences, certain powers and the flight factor. Iron Man is very modern and in this day and age of technology he is at the top, his technological ability is amazing.
