- "All are equal in the court of Camelot."
- —King Arthur to the Legends[src]
Arthur was the King of Camelot in 507 AD. He and his wife Guinevere ruled Camelot together and fought to maintain a rule of peace and justice. Their kingdom's culture and technology progressed far beyond their age due to the guidance of the time traveler Stargirl, who posed as their court mage "Merlin", the chief advisor of Camelot's court. During her time there, Stargirl had fallen in love with him.
Arthur was in the throne room, seated at the Round Table, when Guinevere returned with the Legends. They claimed that they were travelers looking to prevent evil, though he accused them of being in league with the Black Knight who was kidnapping his own knights as of late. He then summoned for Merlin to see if they were indeed trustworthy and the Legends were surprised to see that it was their friend Stargirl, who verified their validity.
Arthur went out on a hunt, and he and his men were ambushed by Damien Darhk. Darhk had him at swordpoint and Arthur claimed he preferred to die then surrender to him. Rip Hunter then appeared and told him that he wasn't going to die and that they had plans for him. He was then fitted with mind control technology from the distant future and made to follow Rip's commands. He led them into his castle where he held a knife to Stargirl's throat as they demanded the fragment of the Spear of Destiny she had. When a fight broke out, he killed Sir Galahad before Rip had him hold a dagger to his own throat, holding him hostage. He was made to fight against his queen and own knights at dawn but Martin Stein and Mick Rory managed to short out the mind control and gave him back control of his senses. He then went out and unhorsed Rip Hunter and helped the Legends take him prisoner. When they were leaving, he pulled Amaya Jiwe aside and told her that their exploits would be forever remembered in Camelot.
Due to the broken time created due to the Legends meeting themselves from different time periods and destroying the Spear of Destiny together, Arthur became an anachronism, ending up in the Spanish Civil War. To prevent time aberrations, Rip Hunter's Time Bureau agents retrieved Arthur and brought him to 2017. Recognizing Rip as the "evil sorcerer" from the times of Camelot, Arthur tried to swipe at him, but was restrained by the agents, before his memory got wiped out.
