If it's anyone's story, it's BMWL's. Only read some of this and she's had a bigger role here than in other events but she's largely a commentary piece/pep-talk giver here. It'd be like calling Blackest Night a Flash event. The only references to her world I can recall coming up amongst others is the Amazons are in some prison dimension and the chainsaw is made from parts of her jet/lasso.
Said it before but I really only think this she has a bigger role here is because WW'84 would have been coming out sometime this started.
