The thing is that it all depends entirely on how the character is written and presented.EmperorSubcutaneous said:Thoughts? Personal anecdotes? Requests for amazing hot chocolate recipes? Post them here!
Batman, for example, is NOT a strong example of a Mary Sue (the male equivalent, btw, is called a Marty Stu, a perfect example of which is actually Gandalf, who is all-powerful, infallible, always shows up at the right moment to save everyone and is basically a living Des Ex Machina), because Batman is often quite well-written AND ALSO because all of the quoted examples are actually in fact integral aspects of his character, rather than simple flavor-text.
(And also actually kind of dismissively over-simplified, imo, but I am biased, as I am a lifelong Batman diehard.)
The difference is that Batman actually acts like the aloof hardassed asshole hero that his backstory defines, rather than have it just be a handful of extra words that don't matter, if this makes sense.
When he is well-written, batman's past creates his character, as it should be.
(When he's not, it doesn't.)
