Matter-Eater Lad (Tenzil Kem) is a superhero in the DC Universe. He is a member of the Legion of Super-Heroes and possesses the power to eat matter in all forms, as do all natives of his home planet, Bismoll. He first appears in Adventure Comics #303 (December 1962). Publication history Matter-Eater Lad first appeared in Adventure Comics #303 and was created by Jerry Siegel and John Forte. Fictional character biography Pre–Zero Hour Matter-Eater Lad is the fifteenth member inducted into the Legion of Super-Heroes, joining soon after Bouncing Boy. In his first appearance, Matter-Eater Lad explains his origins, saying that the natives of Bismoll found that microbes had made all their food inedible, and that the populace evolved their ability to eat all matter as a survival mechanism. This gives his teeth and jaws, apparently, the strength and durability to bite and chew through stone, metal, and other hard substances the way that Superboy Mon-el can. Tenzil's mother is named Mitz Kem, and his father Rall (who, curiously, use Tenzil's LSH stipend to buy groceries as told in "The Hapless Hero" in Action Comics #381, despite ostensibly being Bismollians).

He appears rarely in Legion stories, as the writers struggled with the problem of how to make his power useful in a fight and was routinely written out via a plot device where Tenzil was constantly being drafted into his planet's political system due to his fame as a Legion member. During one of his first draftings to be in politics, he put in a good word for fellow Bismollian, Calorie Queen, who had somewhat similar powers as him, but also had the ability to turn caloric energy into super strength. Matter-Eater Lad has one major heroic moment, though, when he saves the universe by eating the previously thought to be indestructible Miracle Machine, though the energies of the device leave him insane for several years. He is ultimately cured by Brainiac 5. He would later avert the conquest of Bismoll by an army of Computo replicas, with the assistance of the Legion Subs (this mission would cause Polar Boy to disband his group, and join the
