Initially, the team was closely associated with the original Superboy character (Superman when he was a teenager), and was portrayed as a group of time travelers. Later, the Legion's origin and back story were fleshed out, and the group was given its own monthly comic. Eventually, Superboy was removed from the team altogether and appeared only as an occasional guest star.
The team has undergone two major reboots during its run. The original version was replaced with a new rebooted version following the events of the "Zero Hour" storyline in 1994 and another rebooted team was introduced in 2004. A fourth version of the team, nearly identical to the original version, was introduced in 2007. In 2019, DC announced a new series written by Brian Michael Bendis and drawn by Ryan Sook.
