Saving Hawkman would be ridiculously easy but I doubt they'd do it my way. All they have to do is slide Hawkworld back a bit (the exact same way they've done Wonder Woman) and then there's no need for GA Hawkman in the JLA or another Thanagarian. I haven't figured out how to undo the Hawk God crap without just ignoring it tho'. And I haven't forgiven Johns yet for ruining the Golden Eagle character from one of my favorite JLA stories ever but that's just random...
Let's hear it
With the Multiverse back, altering Hawkman & Hawkgirl would be easy.
It seems DC has something cooking. I don't remember it, but someone at the Baltimore ComiCon asked about Hawkman, and DiDio wanted to reply but was cut off by Bob Wayne. Maybe that's a good sign. Let's not forget that he's apparently taking part in Final Crisis, so he won't stay off the radar for long.
