While there was no Legion of Super-Heroes on Earth-Two as on Earth-One, both worlds had their own lethal Legions operating in the 30th century simaltaneously. While Talik the Mute recruited his Legon of Super-Villians through his School for Super-Villains to counteract the heroic Legion, on Earth-Two it was the policy of that planet's government to exile certain criminals to the mining world of Vulcanus, these felons becoming a Space Legion of the Lost. This Space Legion was intiailly a threat to Brane "Batman" Taylor and the 20th century Robin, who attempted to track down space pirate Yerxa, although a clever story kept them from such a confrontation with the rogues. Earth-One's lethal Legion, however, was a recurring adversary to the heroic twins from the teen years until they and their opposite numbers had matured to adult heroes and villains.
