A bit like they do with Superman how the hero is tricked/manipulated/warped into being an adversary the other heroes have to stop. Its been suggested that without her cuffs she is much more powerful but it fills her with rage until shes not herself and almost like the Firstborn. No idea what being God of War has done yet but its fair to assume this is to an even greater degree now. I've seen little snipets in the Justice League where they have alluded to something like this being possible. For instance when Batman shows the empty box and says that Superman is Wonder Womans Kryptonite. Theres also the "Trinity War" arc, suggestive name aside, seems to have the Secret Society subtly manipulating the heroes to make them evil; as they seem to have done to Superman.

Incidentally, have they ever done that storyline with Wonder Woman before? I know its been done to death with superman but from what I know evil Wonder Woman is usually a multi-verse story.

She's a vicious bitch in the Injusticeverse....

WW Odyssey, there was an evil version of her.

Crime Syndicate has an evil Wonder Woman.

She's been upgraded to the Olympic pantheon and has proven herself over and over that she is a reactive violence machine. Just a matter of time before somebody pushes the right buttons and she stabs somebody's eye out.

@kapitein_zeppos: Has she done anything villainous since she became the God of War?
