Kelex is a fictional robot appearing in American comic books published by DC Comics, commonly in association with the superhero Superman. Publication history Kelex first appeared in The Man of Steel #1 and was created by John Byrne. Fictional character biography He first appeared in The Man of Steel #1, in which he was one of Jor-El's Kryptonian Service Robots on the planet Krypton. Presumed destroyed along with Jor-El and the rest of Krypton, Kelex has nonetheless returned as Superman's primary robotic servant within the Fortress of Solitude where he works as its property caretaker. When Kelex first appeared in The Man of Steel, he was only in one page of the first issue, greeting his master, Jor-El, upon his return. Jor-El then orders him to bring the baby Kal-El (who would become Superman) in his birthing matrix. It is revealed in conversation with another of Jor-El's servant robots that Kelex had served Jor-El for all of his life, much longer than the other robot had, and had never seen him like this. The robot didn't appear for the rest of the issue, nor for the rest of the miniseries. He was presumably destroyed along with the planet Krypton. Later, when a Kryptonian device known as 'the Eradicator' was obtained by Superman, it tries to recreate Krypton on Earth, beginning with the South Pole in the Antarctic. Superman stops it, but the attempt had created the Fortress of Solitude. Along with the fortress had been created a group of robotic servants, one of which was a recreation of Kelex. He is largely indistinguishable from the other Kryptonian robots who maintained the fortress. He attends the false Eradicator version of Superman who had taken up residence in the Fortress. Kelex is used as a framing device for a tour of a redesigned Fortress of Solitude. The Fortress of Solitude is dramatically redesigned when Dominus took mental control of Superman. It is then destroyed by Lex Luthor, severely damaging Kelex. When Superman returns to the fortress, he repairs the robot enough to enable him to speak. They were both sent to a ghostly replica of the Fortress, complete in every detail. Superman is able to keep a link to the ghostly fortress through Kelex, now reduced to a head. The robot then assists Superman in a crisis; an android double, programmed to protect Lois Lane, had become defective. Kelex is vital in
