Fictional character biography
Esper Lass 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.

Esper Lass is later seen as a member of the Legion of Super-Villains. Her last appearance prior to Zero Hour: Crisis in Time! was a cameo during Crisis on Infinite Earths.

She was later seen in Final Crisis: Legion of 3 Worlds #2, once again a member of the Legion of Super-Villains. She is later seen attacking Saturn Girl's mind, along with Saturn Queen. In the next issue, she's been mentally blocked by the Saturn Girl of Earth-Prime, to stop her from aiding Saturn Queen.

Powers and abilities
Like other natives of Titan, Esper Lass was born with a number of psychic powers. She can read minds, and exert some mental control over others. In her initial appearance, she proves to have stronger powers than Saturn Girl, and is able to overpower the more experienced superhero.

In other media
Esper Lass appears in Legion of Super Heroes, voiced by Tara Strong. In her most notable appearance in the two-part episode "The Man from the Edge of Tomorrow", she and Fatal Five member Tharok hospitalize Saturn Girl.
