Justice League of America, Vol. 1

Earth 3 in the multiverse is very different from Earths 1 and 2. On that world, Columbus was an American who discovered Europe, Abe Lincoln was an actor who shot president John Wilkes Booth, and the reigning superbeings are the Crime Syndicate of America. Syndicate member Ultraman gains a new superpower with each exposure to kryptonite, and the latest exposure reveals to him the existence of Earths 1 and 2. The Crime Syndicate take time to form a plan to take on the Justice League of Earth 1 and prove their superiority. A conflict on this scale cannot be wrapped up in a single issue, and will be concluded in issue 30.
