Agravaine de Bois

Lord Agravaine de Bois is a major antagonist of BBC's Merlin, serving as the secondary antagonist of Series 4. 
He is the brother of Ygraine Pendragon and, therefore, Arthur's maternal uncle. He seeks revenge on Uther and Arthur, believing them to be responsible for his siblings' deaths. He allies himself with Morgana Pendragon and assists her in her goals to take over Camelot as its Queen. 
==Trivia==
* In the original stories, Agravaine's relationship with the other characters that is vastly different than the portrayal in the TV series. 
**In the original stories, Ygraine, spelled Igraine, is Agravaine's maternal grandmother and not his sister like the series. 
**Agravaine was the second son of Morgause and King Lot, additionally being Arthur's and Morgana's nephew and Gwaine's brother. In Merlin he is unrelated to all the aforementioned characters except for Arthur.
**In some versions, Agravaine is either Mordred's brother or cousin depending on if Mordred's mother was Morgause or Morgana. However, in the Merlin, retelling, Agravaine has no relation to Mordred.
**Along with Gwaine, Agravaine also had two other brothers, named Gaheris and Gareth, though it is unknown if this version of him is related to them, or if they even exist in this canon.
