Agravain is the son of Morgan, making him the brother of Gawain, Gareth and Gaheris, and half-brother of Mordred. He was also an assassin employed by Morgan le Fay to serve as one of the knights. Acting as the secretary of the Round Table, he was one of the few to find out the secret of the King's gender. The affair between Lancelot and Guinevere was discovered by him, and he used the secret of the king to threaten the queen. This act was, however, also his undoing, as Agravain was killed by Lancelot, who was overtaken by rage.
Serving on the Round Table, Agravain often advocated more so than the others of the King's inhuman nature. He often pronounced to the other knights that, "The King is not the incarnation of the dragon; his heart is a single dragon. His magical power is of a level beyond ours. I ask you not to seek the same values as ours from one possessing magic like the gods."
He is calm, calculated and even cruel, always going for the best option at hand. He believes his purpose is to assist the appropriate King of Britain, thus despite Morgan's order, he claimed that he helped Artoria willingly, believing her to be the best king Britain could have. He, however, hates women due to Morgan and was shocked to discover Artoria's gender when exposing Guinevere's affair.
When he is about to die, however, he confesses his real wish was to build a perfect kingdom for his king. It wasn't that he served the king for the kingdom, but the kingdom for his king. The only person he doesn't want to be hated by.
Agravain, along with the other Knights of the Round Table, is summoned by the Lion King in the "Camelot" Singularity. The Lion King gives the knights the option to either aid her with her "Holy Selection" or side against her, giving them a half a day to decide. Agravain ultimately chose to side with the Lion King and, along with Lancelot, Gawain, Tristan, Gareth and Mordred, defeated and killed his fellow knights., forming the Knights of the Lion King. The Lion King then gave them each a Gift, though Agravain refused to have one, claiming he had no need for one. He also didn't want to completely submit to the Lion King, due to the possibility of having to face her in the future.
Agravain and the other knights then overtook on the "Holy Selection", killing all that stood in their way throughout the Holy Land. They engaged in battle with the False Crusaders, easily defeating them until facing their leader, the Servant calling himself Richard I. The knights were at a disadvantage in the battle, due to the great strength of their opponent, until Gareth grabbed hold of him, restraining him with her own body and giving the others a chance to strike. Agravain prepared to deal the finishing blow, but Gawain attacked before him, killing both Gareth and their opponent. This caused the Holy Land to fall into the hands of the Lion King and her knight, who established the Holy City.
Camelot: Sacred Round Table RealmEdit
Although he rarely fought on the front lines, he gained the moniker "Agravain who knew no wounds" because would always return uninjured whenever he went to battle, no matter the strength of the opponent. He is a very capable fighter, defeating and killing even Lancelot who was summoned as a Saber, but only after drugging himself and boosting his capabilities in a manner similar to Mad Enhancement, and is left mortally wounded afterward. Agravain is mentioned being infamous for his capabilities in interrogation and torture, said to be skilled enough to even make a hippopotamus squeal for mercy in human language. He also possesses chains called the Iron Commandments, that are specifically made to bind Servants.
As part of the Round Table, his attitude earns him general dislike, but no doubt excels as the king's secretary. Bedivere notes that Camelot's fall accelerates only after his death, and he may be the most important person holding the Table together, a sentiment Mash agrees with, as her Saint Graph remembers, causing her to feel that "If this man is around, then the King will be alright".
