*One year after meeting the Legion, Supergirl is once again invited to try out for membership. In the 30th Century, she is told that new rules allow two new members to join each year, and meets several other applicants, including Brainiac 5, the descendant of the original Brainiac, one of Superman's greatest foes. She distrusts him until, after her own initiation test, he risks his life by giving her his force-shield belt to protect her from a giant Kryptonite meteor.

Along with Brainiac 5, who allows her to keep the belt, Supergirl is inducted into the Legion. She returns home confident that she'll never have to worry about Kryptonite again; however, an explosion damages the belt beyond repair, and she is vunerable once more. *Source: The Official Legion of Super-Heroes Index #1 - Published by ICG.
