Lancelot is one of the knights of the Round Table, and Suzaku is knight
They are all betrayal knights, who are not understood or even spurned by the world for various reasons, but it is understandable that their beliefs are all good.
Just like DK, they were great guardians at first, because the inner darkness was exploited by the Lich King and they betrayed the people they guarded. Now he betrayed the Lich King because of Fording and Ashbringer and regained his former glory. Although they are still not understood and accepted by people, although they are still called "traitors" by people, DK people still stick to their beliefs to protect their loved ones (people).
DK requiem!
