Esper Lass

Meta Ulnoor is from Titan, the moon of Saturn, in the 30th century. Like other natives of Titan (including Legionnaire Saturn Girl), she is a natural telepath. After being rejected for membership in the Legion of Super-Heroes (due to a rule prohibiting members with duplicate powers), she joins a group of fellow rejects and demands membership. Calling themselves the "Legion of Super-Rejects", they are initially victorious over their like-powered rivals. Esper Lass and the Super-Rejects are eventually defeated when the Legionnaires use teamwork to win.
