In August 1941 a team debuted that would endure for decades to come. As high flying aviators combating the Nazi regime and other treats to humanity, the Blackhawks consisted of the following:
Blackhawk - The group's leader, Bart Hawk, a Polish American
Andre Blanc-Dumont - He is a French member of the this group.
Olaf Bjornson - He is either from Norway or Sweden.
Chuck Wilson - He is an American from Texas.
Hans Hendrickson - He is a Dutch member of the team.
Stanislaus - He is another Polish member.
Chop-Chop - Named Liu Huang or Wu Cheng
And, of course, their unofficial member Lady Blackhawk- Zinda Blake, the counterpart of Dinah Drake Lance whom we previously considered.
And yet, their multiple appearences in latter years beside various superheroes from different eras, and different worlds, caused no shortage of confusion as to whether there was more than one set of seven such soldiers. And indeed there were, for the first such team (appearing in Quality Comics) resided on Earth-Two, that is until Uncle Sam recruited several freedom fighters from that world to the parallel planet of Earth-X in 1942 with no resident heroes up to that point. When the Freedom Fighters reappeared in 1973, only six costumed crusaders remained on that world (Firebrand would show up later), stating that their fellow Quality comrades who aided them against the Nazis had perished. Specifically spotlighted were the Blackhawks and Plastic Man. A second set of Blackhawks, the ones who appeared when DC Comics acquired the Blackhawks' title from Quality in January 1957 onward, resided on Earth-One. Those tales chronicled their modern day adventures, while a latter reappearence of their publication in the 1980's showed their tales during the 1940's (confusing isn't it)? However, two oddities have thus far not been reconciled, until today. First, the Earth-One Blackhawks, who battled during World War II, appeared unaged and still in their prime alongside the Justice League... in the modern day... decades later! And the Earth-Two Blackhawks appeared alongside that world's Batman in September 1944, two years after they supposedly left for Earth-X!
This can be explained a few different ways. First, we may postulate that during the Crisis on Infinite Earths which distorted space and time (at which point Earth-Two's team left for Earth-X), perhaps the Earth-One flying aces were plucked from the 40's ending up in the 60's/70's to work alongside the League. The second possibility is that the original teams inspired copycats to duplicate their idols, even going by the names of the first Blackhawks on each world. It is known that Kid Eternity pulled the Blackhawks from "Eternity" to his native Earth-S where they operated at through the mid-1950's.
