Element Lad, Shadow Lass and Matter-Eater Lad were members of the Legion of Super-Heroes that may not have been the most famous but were nevertheless critical to that team's success in its later exploits during the 30th century. Jan Arrah was the sole survivor of planet Tron and possessed matter-transmuting powers. Blue skinned Tasmia Mallor of planet Talok VIII has alongside her cousin been given hereditary shadow casting powers. And Tenzil Kem had, like others from the world of Bismoll, the ability to consume any substance.
Their counterparts on Earth-Two were the 30th century descendant of the hero known as Sargon, who like his ancestor had the ability to control and manipulate matter he touched, Blue Lama who was a blue skinned villainess who was a frequent foe of the original Sargon, and in fact made herself appear as the later Sargon on one occasion, and a clone of Sargon's stage assistant Maximillian O'Leary who like his "father" had an obese appearance from over consumption which also was a hallmark of Matter-Eater Lad who was obese for a time.
