Part Two of the second JLA/JSA crossover!
The story: "The Most Dangerous Earth of All!" by Gardner Fox, Mike Sekowsky, and Bernard Sachs. The JSA fights the Crime Syndicate, but is tricked by them and they get transported to Earth-Three. So the JLA then goes to Earth-Two, and defeats them there.
Realizing they can't return them to their homeworld, Green Lantern uses his ring to place them in an inter-dimensional prison bubble, all alone, covered in warnings to potential visitors(?). When last we see them, they have no water, no food, no beds...the five of them are just in a small bubble. This would inspire the later Marvel series Crime Syndicate Zombies.
Roll Call: Superman, Batman, Wonder Woman, Flash, Green Lantern
Notable Moments: The JLA and JSA barely interact in this story; in fact they only share a few panels together, and most of those are on view-screens, ala Kirk and Khan in Star Trek II.
