Arthur (Circle) (Earth-616)

Arthur was the leader of The Circle, a group of mercenaries based on Arthurian ideals, with the main purpose to defend Symkaria from Doctor Doom and Latveria. During an auction run by A.I.M., the Circle bought part of the replicated Extremis technology, creating new and better exoskeletons for their own purposes.

After they noticed Iron Man was in the search of the Extremis which A.I.M. stole, he proposed Stark with a wager, if Stark defeated the Circle's Extremis-enhanced pilots, he would be free to retrieve the Extremis. During the battle, Stark noticed that the Circle's force field, which protected their sample of Extremis, was light-permeable. Stark was able to destroy their Extremis using a potent U.V. laser causing the loss of all the Extremis they had left and rendering them unable to continue producing new technologies of their own.^[1]

When the powerful material Phlogistone was found on the Moon, the Circle was sent to Tranquility Gulch, the human colony from which the Phlogistone was studied, as representatives of Symkaria.^[2] They later helped Iron Man attack the embassy of the country of their common enemy, Doctor Doom, in an attempt to prevent any Phlogistone from reaching Doom's hands.^[3]
