This is the list of Legion rejects at the time of the latest issue of the retrospective that I have reviewed.
Please note that members who are rejected but join soon after (people like Supergirl, Bouncing Boy or Wildfire) are excluded.
Note that several rejects join during the “Five Year Gap”, the period between volumes 3 and 4; we learn about their membership only through vague references and quick flashbacks, so their membership is a little questionable.
I’m also tracking whether they become supervillains (many join the Legion of Super-Villains, as noted in the table). A couple of them are villains only in the continuity after Infinite Crisis, which is kind of the same continuity of pre-Crisis, except not really.
NOTE: this does not include the 5YL era.
