An Even Fight
Sounds like everyone is evenly matched:
Superman vs. Icon (same back in Worlds Collide)
Flash vs. Blitzen
Wonder Woman vs. Donner
Hawkgirl vs. Iron Butterfly
If only there were Steel vs. Hardware (rematch from Worlds Collide), Atom vs. Iota, Negative-Man vs. Twilight......
Overall, the fights are good....surprised that Superman and Icon are friends (because Superman does not remember the event after Zero Hour, Icon remembers the event).
And Hawkman coming back to warn everyone of Shadow Thief....might have been or have not been easy to figure out with the keyword 'shadow' for this story-arc.
