I know it has been talked about elsewhere and I am never one for discussing future developments in comics (I prefer to read them as they come- that having been said there are spoilers ahead) but I suppose as someone who knows a fair bit about Wonder Woman that I should let me own thoughts be known on the revelation that Zeus is in fact her father. I will break this down into pros and cons:
1. This is a story which I have being saying for some time needs to be told. There are a lot of potentially great Wonder Woman stories out there waiting to be told, and I think that this one in addition to her finding a meaningful romantic interest are two of the major stories which could be told. In that I am happy that this story is now going to get told.
2. Another one of the great missed stories in Wonder Woman I always felt was Diana as goddess (this was during the John Byrne run.) This new development will give a new dynamic with the gods, more as equals as opposed to superiors.
3. I think by putting more of a male approach into the Amazons that a lot of the negative associations which they get (accusations of being lesbians chiefly among them) will mostly dissipate. It will no longer be possible to reference some obscure panel from the 1980s to show that all Amazons are lesbians.
1. A lot of great stories now become non-canon, including one of my favourite story arcs, the Challenge of the Gods (well this actually isn't the case, but one scene would lead itself to incest- but then again it is Zeus.)
2. It is not that closely related to any mythology either. The Gallilean satellites of Jupiter (yes I am talking about astronomy again - Callisto, Io, Europa and Gannymede) are so named because of Zeus' relations with them (which were not always consensual.) Regardless there is no Hippolyta moon on Jupiter and that's because there was never a reason to. I don't mind so much updating mythology, but when there is such an overwhelming amount of canon in comics and myths from antiquity which support a claim then there is less reason to back it up.
3. The imposition of a father figure fundamentally alters Wonder Woman's history. This is not so much of a problem (I never really liked the shaped from clay idea) but one of the best Wonder Woman stories is her emergence from the Cavern of Souls. While this is not as prominent an aspect of her origin as it is relatively more modern (from the Perez run) it is maybe not seemingly as important, but in comparison it would be the equivalent of saying Superman did not escape from an exploding Krypton or that Batman was not born in Crime Alley.
One which I am not yet sure of is the association with Zeus. It does fit his profile, but it also seems like an easier story to tell. Another god might have been more interesting, but I am going to give the writer the benefit of the doubt and read the story before I actually judge the choice.
