The first time this connection was made, was when Hulkling was a member of A.I.M.. He was kidnapped by the "Knights of the Infinite", an analogy to the Arthurian "Knights of the Round Table" and told, that he was the prophesied ruler of the united Kree/Skrull Empire. He was then told to get a sword out of a light beam and announced "King of the space". That's an obvious adaptation of the famous Arthurian legend of the sword in the stone. Hulkling even named his sword "Excelsior", Arthur's sword was named "Excalibur". Two of the knights seem to be named after characters of the Arthurian Mythos, Lan-Zarr (after Lancelot), Mur-G'nn (after Morgana, also an Magic user). There is also M'ryn the Magus (named after Merlin), an old Magic user, who spoke the prophecy.
