It only sounds "cool" because of familiarity; it's engrained into your head and a natural part of your psyche now. There are plenty of "goofy" words that sound completely ordinary to us. "Movie" and "computer" being two prime examples.But, see, that's what I don't get: Stan went to great lengths to come up with a name that sounded cool for "Spider-Man", and not goofy.
Crows are arguably just as cool as bats. But "Batman" sounds cooler than "Crowman" simply because of the aforementioned reasons. Whereas in reality they're both pretty stupid.
