Issues

 * 1) /I'm Just A Kid, Part 1/ - all across America, adult superheroes have gone missing, ranging from well knowns such as Batman and Superman, to lesser knowns such as Icon. It is up to the teenage heroes to find where their mentors have gone. Mysteries, horrifying discoveries, and misunderstandings are a plenty.
 * 2) /I'm Just A Kid, Part 2/ - Superman has appeared on live television and announced that the Justice League's new primary function will be the eradication of mankind. While not officially a team yet, the teen heroes are still doing their best to figure out the origin of Superman's new mindset while also dealing with their former mentors, who have begun hunting them.
 * 3) /I'm Just A Kid, Part 3/ - in the conclusion of Teen Titans' opening arc, the teen heroes are forced to work as a team for the first time when they are trapped inside the dungeons of Dark Opal's palace in Gemworld. However, even if they manage to make it to Dark Opal's throne room, they must still defeat his personal guards: the Justice League themselves.
