Phyl Staad was one of several super-heroes that were captured by Nardo, the warden of a prison planet. The Legion of Super-Heroes were also prisoners of the planet. The various heroes made several attempts to escape, and finally succeeded. Unfortunately, Phyl gave his life in order to protect Matter-Eater Lad during their escape.
