Young Justice

Origin

Robin, Superboy and Impulse interceded on behalf of a D.E.O. "cleaner" team transporting a gaseous entity known as Secret to the Wabe Facility for disposal. Working together, the teens were able to rescue "Secret" from her D.E.O. captors.

The teens later found themselves at the epicenter of the conflict involving an ancient Atlantean force which possessed Boston teenager Matthew Stuart and somehow granted him godlike powers. Stuart, calling himself Bedlam, was in fact responsible for transporting our world's entire adult population to a simulated Earth devoid of children. Stuart, while under the mystical influence, allowed the remaining adolescents to have destructive free rein until Robin, Superboy, and Impulse (as well as the aduIt Captain Marvel) defeated him.

Following this adventure, the threesome decided to remain together as a team. Adopting the JLA's " Secret Sanctuary" in Happy Harbor, Rhode Island as their de facto headquarters, the team soon found themselves on their first adventure unearthing an ancient vehicle appearing to be a so-called "Super-Cycle" of New Genesis origin. Meanwhile, former Justice League member Red Tornado awoke from stasis and became the mentor to the fledgling team, who had accidentily acquired the name "Young Justice."

New Members

Soon after, some girlpower was added when Wonder Girl, Arrowette and Secret joined the team. Arrowette left the team after a traumatic adventure while other members would join the teenage team, including the mysterious Empress, the incorrigible Slobo and the Ray.

When Secret was turned to the dark side by the demonic Darkseid, Young Justice was faced with perhaps their greatest challenge. Robin was able to bring Secret to her senses, but the victory was both bitter and sweet; Secret reverted to human form (her fondest wish) but Slobo sacrificed himself to save her from Darkseid.

Graduation Day

Shortly afterward, a conglomerate known as Optitron offered to sponsor the Titans and Young Justice after summoning them to San Francisco. Before any decisions could be made, a mysterious cybernetic girl known as Indigo emerged from the future. Unwittingly, she somehow activated a rogue Superman android, resulting in the apparent deaths of Troia and Omen. At Troia's funeral, Nightwing disbanded the Titans.

At Troia's funeral, Nightwing declared to Arsenal that he is tired of seeing friends die and the Titans are officially over. Meanwhile, members of Young Justice, especially Wonder Girl, felt responsible for the tragic deaths. This led to Wonder Girl, Robin, Impulse and Superboy forming a new group of Teen Titans under the guidance of the more experienced Cyborg, Starfire and Beast Boy (later joined by Raven).
