Wildfire and Dawnstar are testing four Legion Academy recruits to see which will join the Legion. As former enemy Blok recounts his origin, the team is called to recapture the escaped Starburst Raiders.

The Legion of Super-Heroes are having tryouts for potential new members and they have four applicants to test: Crystal Kid, Nightwind, Lamprey and Blok. Dawnstar, Wildfire and Sun Boy head the tryout process and inbetween trials, Blok shares his origin with the other applicants. Before too long, the Legion are called to assist in a prison outbreak and the Legion decides this is a good time to gauge the applicants. The only one to do well and defeat those breaking out was Blok, so he is invited to join the Legion of Super-Heroes. He readily accepts.
