The Paul Dini/ Alex Ross origin of Batman does have a panel showing him with extensive scarring across his back, but that visual was taken from a scene in Alan Brennert and Joe Staton's Brave and the Bold #197 "The Autobiography of Bruce Wayne" and is intended to show the effects of a lifetime of hand-to-hand combat, explosions, death-traps, and pushing oneself to the extremes. It does not depict childhood abuse.

The idea has since turned up in other Batman tales as well.

Eric, I recall Mike Baron making the change in Wally's father in the first issue of the Post-Crisis Flash. The father was later revealed to have been a Manhunter.

Captain America recent MarvelNow #1 revealed that his dad was not only alcoholic, which we knew from O'Neil's second run on Iron Man, but also abusive, the point apparently being that Cap learned his concepts of bravery, sacrifice, and heroism from his mother.

The abusive father element of Bruce Banner's backstory was introduced in the Incredible Hulk #312. Of course, Mantlo is considered fair game for charges of plagarism after the "Hero" debacle in which he took a great many elements of Harlan Ellison's story "Soldier." Seriously, of all people, why take from the famously-litigious Ellison...? I cannot fathom it...

Now that Wonder Woman's origin as a figure of clay given life by the gods is a thing of the past and she's just one more of the veritible pantheon of Zeus' bastard children, I wonder if the abuse heaped upon the amazons by the gods now puts her in the "abusive father retcon" category. If nothing else, it does visit the "emotionally distant father" trope upon her, as so many superheroines before her have had done to them before...

I wonder if Plastic Man, now a more gritty and realistic vision of a criminal and a father himself (a couple of times over, if I'm not mistaken), has had this abusive father concept trowelled into his past...

William Messner-Loebs tried to redeem Rudolph West (a bit) by making him more of a chancer and a con man that always failed rather than right out evil which is what happened in Baron's run. He joined the Manhunters and arranged for Wally's mother to have a fatal accident whilst on a cruise. Charming.
