Arthur Pendragon vs. Hendrickson

Arthur Pendragon vs. Hendricksen is a battle fought between Arthur Pendragon, king of Camelot and Great Holy Knight Hendricksen.

Prologue
As the entire order of Liones' Holy Knight focused all their efforts to prevent three of the Seven Deadly Sins: Meliodas, Ban, and Gowther from breaching into the kingdom, a large force of Camelot's Holy Knights appeared out of nowhere massing outside the walls of Liones with the new king of Camelot Arthur Pendragon leading them fully-armored and riding a large warhorse accompanied by a mysterious cloaked person.

Great Holy Knight Hendricksen decides to confront Arthur by himself while Dreyfus deal with the Seven Deadly Sins after convincing the latter that they'll discuss the matter between themselves later.

Accompanied by two Holy Knights, Hendricksen remembers the time when a sword fell from the heavens and stuck itself in the stone at Camelot and every Holy Knight attempted to pull it out, only to fail until Arthur managed to pull it out and became Camelot's new king. Adding to the fact that Camelot is a growing power over the past few years and has yet to be on par with Liones but has sensed multiple powers among the Camelot army much greater than those of Liones' Holy Knights themselves. After ordering that the gates be opened, Hendricksen faced the Arthur and asked of his presence in Liones with an army. King Arthur revealed that it was a ruse in order to get the Holy Knights' attention as the cloaked individual removed the illusion, shocking the other two Holy Knights and surprising Hendricksen. When Arthur requested an audience with King Liones, Hendricksen lied that their king is unwell and is treated by the kingdom's finest mages. Arthur then humbly asked the Great Holy Knight that his cloaked friend will help curing the king's illness but Hendricksen wouldn't allow that, while trying to hide his frustration in dealing with a foreign king. Demanding that Arthur should leave, the latter insisted that he's not leaving until he meets King Liones and offered the Holy Knights assistance in dealing with their little problem whilst removing his helmet.

Reluctantly, Hendricksen led King Arthur and his cloaked friend into the castle followed by two Holy Knights. As they walked, Hendricksen questions King Arthur how did know of the problem they were having, only for the king of Camelot to reveal that he made that up. Suspicious of his care-free nature, the Great Holy Knight asked King Arthur again, this time what was he after, but the latter playfully refuses to tell him. The Holy Knights surrounded King Arthur and his cloaked friend as Hendricksen states that they killed every foreign messenger who came to visit Liones even if he was the king. A mysterious female Holy Knight appeared and informed Hendricksen of the situation. After Hendricksen gave orders to the female Holy Knight to retrieve their target no matter what as she teleported away and bade Arthur and the cloaked person good luck and good bye, King Arthur asked if that Holy Knight was a Liones mage only for the Great Holy Knight to attack him, stating that he won't live to find out as he performed a huge slash that sent the young king flying into the building. Hendricksen soon received damage and realizes that Arthur's reputation wasn't for show as the latter is revealed to be unharmed, blocking the attack with his Holy sword while at the same time, wounding Hendricksen. Arthur then comments the powers of the Great Holy Knight as he prepares for battle. The two Holy Knights expressed their wish to support Hendricksen, but the Great Holy Knight calmly tells them that their opponent is above them as Arthur's cloaked friend floats behind them.

Battle
The clash between the king of Camelot and the Great Holy Knight in form of huge explosions round buildings was seen by the three Sins to which Meliodas quickly assumed that Elizabeth is there and immediately proceeded to that area followed by Ban while Gowther heads to aid Diane against Dreyfus and his subordinates.
