List of members/LSH cartoon

The Legion of Super Heroes cartoon premiered on September 23, 2006 on the CW Network (in the US). In the series, a number of Legionnaires travel back in time to recruit Superman to help them in their time, his future. Unfortunately they go back too far and get Clark Kent before he became Superman, before he mastered his powers and moved to Metropolis. In the 31st Century, the Legion teaches Clark to use his powers and Clark teaches the Legion how to be heroes.

The series has thirteen half-hour episodes each in Seasons 1 and 2. This list is complete through the first two episodes of Season 2. The series focuses on several core Legionnaires (noted with an asterisk in the lists below), with a number of members who only show up on occasion. Until the show airs episodes dealing with the Legion's origin and history, the order of joining is unknown up to the point where Superman joins.
