Batman mostly fits the superhero archetype however does have some differences.

• He has a weakness however unlike the normal superhero it’s not an object like superman as his cryptonite. His weakness is his morals on not killing people.
• He has an alternate persona similar to spider man or iron man. However with Batman’s persona who chooses to wear dark clothing and not typical bright blue, red and gold that is often seen on superheros.
• Last he makes a sacrifice and with all other superheros it messes with there morals. However unlike most superheros, Batman’s choice stops him from being seen  as a hero.

Overall he does fit some of the superhero archetype however tends to change the way we see those elements.  I would prefer to call him a tragic hero that has a superhero disguise over him than anything else. It is his own flaws that cause him to suffer.
