Legion of Super-Villains(Mainstream Universe)

The Legion of Super-Villains was a group of super-powered teenagers active on Earth-One in the 30th century. Following the Crisis on Infinite Earths, the team's history continued on the resulting New Earth. This timeline was later erased by Parallax during the Crisis in Time. However, following the events of the Infinite Crisis, their history was restored on the newly formed Earth-0. Some time later, Doctor Manhattan altered the past, removing this team from the timeline once again.
