The continuity of DC makes this type of thing a pain in the ass, especially as I tried to put teams together in their original incarnations. It gets complicated as there are individuals that cross over on teams, or who are originals on Earth-One, Earth-Two, New Earth or on none. Then you have characters with multiple incarnations like Robin, so if I wanted to do the original Teen Titans, I couldn't do the current Titans. So basically I said "fuck it" and just did the teams I liked with the members that I wanted. I did try to stay away from currently "dead" characters, but I still used some like The Martian Manhunter.
So we will say that this is before J'onn died, after the Alpha Lanterns were created, after Barry Allen has returned and before Wesley Dodds died.
Impossible? HA HA SUCKERS! It is DC. 
Oh and these all go together. End to end. When it is done, it will go around in a big circle. So if you wanted to print them out, they would mesh.
Also, I took some creative license with some of the characters and costumes and used a couple incorrect costumes. Most notably The Metal Men, (complete redo), Mary Marvel, (a combination of her old and new personality), Katana (old slutty costume because her new one is butt ugly), Nightwing (added the symbol) and the Sandman (made it a more realistic gas mask).
