 In Morrison's version, the child Damian Wayne is the result of a tryst between Batman and Talia, during which the Dark Knight claims he was drugged when they were at the Tropic of Cancer, though Morrison later admitted the claim of drugging was a canonical error on his part.Since then however in issues of the Morrison penned "Batman Incorporated", the drugging is reaffirmed and is once again part of Damian's origin.The final issue of "52" (2008) designates the "Kingdom Come" alternate universe as Earth-22, thus making the Ibn al Xu'ffasch version part of the DC Multiverse and Damian Wayne's parallel universe counterpart.
