Unlike the Clark Kent of Earth-One, the Clark Kent of Earth-Thirteen got into comics as a kid. This inspired him into making himself a homemade suit and starting to fight crime. He exposed the criminal activities of Bruce Wayne, who set out to kill Clark. When Earth-Thirteen was destroyed, Clark escaped through a portal to Earth-One. Bruce followed him there and killed him.
- The origin of this Clark Kent is unknown. He was seemingly a being without superhuman abilities. However, it is unknown if he was a human or a powerless Kryptonian.
- Earth-Thirteen's Bruce Wayne refers to Clark as a "pansy". This indicates that Clark might have been gay.
