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.

A second Blockade Boy did join the Legion briefly, but he was actually Chameleon Boy's pet, Proty II. He, along with Biron the Bowman, were inducted as members in order to discover the origins of various crime machines.[1]


  • This version of Phyl Staad (Pre-Zero Hour) is no longer considered part of canon continuity. All history and corresponding appearances of Phyl Staad (Pre-Zero Hour) were erased from continuity following the events of the 1994 limited series Zero Hour: Crisis in Time.
