It's the startling conclusion to the Team Titans and New Titans war with Lord Chaos!
Total Chaos part 9 of 9. Donna Troy, now the godlike and half-insane Troia, have brought the New Titans and Team Titans to the former site of Titans Tower. They, aided by Aqualad, plan on defeating Lord Chaos and rescue the newborn Robert Long. Lord Chaos, though, has opened a portal to his future, and has brought through his army. The heroes attack, and are confronted by the armies of Lord Chaos. As they fight, the Team Titans are joined by their old drill sergeant, Battalion, who has come back in time as well.
During the fight, the entire structure is teleported to the Planet of the Gods. Once there, Troia and Lord Chaos are confronted by the Titans of Myth. The Titans know that Lord Chaos is not of this world, and they erase him. They also realize that Donna Troy is not ready for the powers within her, and decide to remove them. The Titans remove the powers within both Donna Troy and her newborn son, allowing them to live normal lives. Donna and her husband Terry Long are reunited, and the heroes are returned to Earth.
