Summary
The year is 1988. Clark Kent is a 14 year old boy living in Smallville, Kansas. He's a quiet, kind-hearted dork who loves comic books and is keeping one of the greatest secrets in human history, namely that he is secretly an alien from outer space. As far as the rest of the world is aware, UFOs and ghosts and all of that "weekly world news" stuff is just as fictional as the superheroes in Clark's comics, and so he keeps his secret, always wondering where he came from and always wondering what he could accomplish if he had the courage to stop hiding and start using his alien abilities to help people, like the heroes in the stories he reads.
One night, Clark is attacked by time traveling villains who seek to wipe him out before he can become a threat to them, and is rescued by J'onn J'onzz, the Martian Manhunter, who received a message from his future self warning of the temporal incursion. Clark must then go on the run, evading the cabal of supervillains who are trying to kill him, and find and recruit other strange kids with strange abilities and backgrounds who will one day join Clark in founding the Justice League of America.
That is, if they can survive.
