Although time travel stories in comics books are frequent, the series is different from most in that it actually takes place in the 30th Century. Legion of Super-Heroes stories contain more elements of fantasy and science fiction than most American comic books.
The Legion is also known for its sizable roster. Most Legion line-ups include more than a dozen minor and major characters. A common visual associated with the group is a tidal wave of colorful heroes utilizing the group's "flight rings."
The team was originally closely associated with Superboy and was first portrayed merely as a group of time travelers who frequently visited the young Superman. It was several years before the Legion’s origin and back story was fleshed-out and the group's connection to Superboy was loosened. They have since remained a somewhat popular DC franchise.
