Tyrannko the Dino-Czar was the leader of the Subterranosauri people, and father of the Subterranosauri warrior Krull. As Dino-Czar, Tyrannko was the head of all law enforcement as judge, jury and executioner. When Krull attacked Metropolis, he was quickly stopped by Samson and Atlas, Superman returned Krull and his warriors to the underground, seeking audience with Tyrannko for the attack. The Dino-Czar revealed that his people had always held a deep respect and fear for the Man of Steel, and that Krull claimed he was goaded into attacking Metropolis by Samson himself, though the Dino-Czar revealed that his son would still feel the full wrath of the punishment of the Subterranosauri law system.
