t-mans comments 

having had a third opnion by someone with more knowldge of the subject, what t-mans posted is factually correct even if as pointed out by the editor in need of some copy-editing  

some copy-editing later
an editor came up with this:

Alongside Clayface, a resurrected one-off concept from 1940 (there are 6 resurrections in total).

In the 1970s, new Batman villains begin to adopt influences from horror and realistic crime fiction (secret agent films), first with Man-Bat (who unlike Batman, is a real human/animal hybrid) and the later with the master criminal Ra's Al Ghul and his daughter Talia, the first villains to learn Batman's identity. (very ok!!!)

The less famous villan, but often equally charismatic Ventriloquist, KGBeast, Black Mask and Killer Croc emerged iduring the 1980s.

More common criminals, such as the Gotham mob leader Carmine Falcone were also added to the villain lineup

The 1990s were notorious for the introduction of the Joker's assistant, Harley Quinn who appeard exclusivley in the cartoon series.

Bane, was the only villain to physically humble Batman. Hush and a new Red Hood are the most famous inductees in the 2000s, due to their connections to Batman's past

 

T-Man put his crap back... I will leave it because unlike T-Man, I have a job, and am going to the gym.  I fixed some typos and grammatical errors, but the POV and moronic comments are too numerous to fix easily.  The great wikipedia project... destroyed by the dim-witted.  

At least is the POV of somebody ho actually reads the comic...not from some... well I already said this above. Cut the insults, please.
