Batman, the ultimate Mary Sue?

I refer you to the tumblr of Scifigirl47 (scrolling back to today and yesterday) for her hilarious comments to people wanting her to write about Bruce Wayne and Tony Stark, leading to her broader analysis of Bruce Wayne and Batman.

Some particularly choice excerpts:

"YOU DO NOT WANT ME TO GET STARTED ON BATMAN. YOU DO NOT.

Biggest frickin’ Mary Sue in the history of comics. Rich, tragic past, no powers but able to handily defeat people with super powers, smarter than everyone, tortured mental state, sacrifices himself so that others may live…

Give him a pair of purple eyes and he’s out of bad fanfic."

and

"Pretty sure the backyard of Wayne Manor is filled with unmakred graves of Gotham’s Child Protective Services caseworkers."

Not to mention:

"...any fic I wrote involving Bruce Wayne would be just Tony making fun of his car.

“The Batmobile: made possible by a joint venture of Hummer, Pratt and Whitney, Wayne Enterprises, and the collected tears of a generation of designers and engineers. Seriously, did you get them drunk, slam their faces off the nearest tank, and while they were still disoriented and bleeding out the ears, force them to the drafting table? This is… This is horrific. Do you get laid? I cannot imagine you get laid.”
