Behind the scenes

  • In the DC comics, this item is called the Legion Flight Ring, engraved with the signature "L" of the Legion of Super-Heroes, a superhero team from the 31st century. Its wearer gets the ability to fly in both atmospheric environments and outer space. In many stories, Superman, as a former or reservist Legionnaire, is also seen having in his possession a flight ring, keeping it in his Fortress as a reminder of his time spent in the 31st century.
