If YOU had switched some Superman, Batman, Wonder Wonder & Hawkman characters with some
Captain America, Iron Man, Thor & Black Panther characters to each others' universes and having
them to never remember everything from there, how different would you have things be?
How many characters would you swap?
And finally, how would you make the characters' Copper Age
origins similar, but not the same as their original ones?
Note: Copper Age is another term used for the era of comic books that existed after the Bronze Age, this scenario won't start out with a Crisis event, you can only have the characters' backstories resemble their
CA ones (like those from our world), those origins won't change at all, this whole thing will take place in
story, the characters will live in each others' cities, all real and fictional american cities will remain in their respective universes, chars who're related to the ones getting swapped can go with them and the non humans races of some chars (related and otherwise) will get swapped too.
Also, Modern Age characters who are related to the swapped ones would have to be
related to somebody else. For example, Terry Sloane
's DNA + Talia al Ghul
