But how can she be Ares' daughter when Ares has been locked up in a prison beneath Themyscira until a few years ago? Unless, as some people suggested, the prison was majorly insecure, and he could sent out his astral, ectoplasmic, and/or, at some level, physical self into the world without anyone noticing, I'm not sure how he could manage it.
(Swamp Thing had a daughter with Abby Arcane - at least, in some continuity - through the stratagem of possessing John Constantine's body and using it to make love to Abby, because his Swamp Thing body didn't have the capability to conceive a child. While he was in John's body, he had a tree tattooed on his butt. Strange story, but interesting!)
