Clarent Blood Arthur: Rebellion Against My Beautiful Father (我が麗しき父への叛逆クラレント・ブラッドアーサー, Waga Uruwashiki Chichi e no HangyakuKurarento Buraddo Āsā?) is the full power, released form of Clarent utilized by Mordred, a transformation into an evil sword of hatred upon the condition of her holding it.[1][2] It is not the proper nature of the sword, but an effect of the episode in Mordred's legend where she had stolen the sword from King Arthur's armory and then later used it to deal a fatal blow to her father.[2] It is an application of Mana Burst that allows her to force her excessive hatred for her father into the sword in the form of magical energy, and then the sword amplifies it and allows it to be launched as an attack.[3] It manifests red lightning, her twisted feelings for her father that have been amplified by the sword, and directs it at the opponent.[3] Mordred feels the weapon possesses a "curse‐like glory", not allowing herself to be defeated by anyone who is not her father, and even more so, not permitting for the sword that delivered a fatal blow to her father to fail in killing an opponent.[2] Compared to the pride felt by other Heroic Spirits, it being crowned with the name of her father makes it more akin to a grudge in Mordred's case.[4] Should she make peace with her discord towards her father, even one-sidedly as in the Great Holy Grail War, she can still launch the attack regardless of her feelings towards her father as an innate talent inherited from the blood of the King of Knights.[3]

Upon utilizing it, she takes a stance, while at the same time, her helmet, Secret of Pedigree, is removed due to the requirement of it being released before she can use the attack. The space around her and the sword becomes stained with dark red blood, and the blade of the sword, enveloped by the radiance of blood, gives off strange, violent and furious sounds and begins to transform.[2][4] Changing from Clarent's normally pure and beautiful form, her great hatred transfigures the sword into that of a sinister and wicked blade befitting a demon, a "demonic sword of calamity".[1][4] Transformed into a grotesque and unsightly form, red lightning flickers through the surroundings as it is clad in her wanton hatred.[1][2][4] Upon raising the sword, she releases the blood radiance upon the enemy as a flash of light, a surging wave with the simple purpose of destruction. It releases a straight line of crimson lightning from the tip of her sword, destroying all in its path.[2][4] Utilizing it takes a great deal of energy, giving her intense pain throughout her body, but her Master's competency allows her the strength to move immediately after utilizing it.[2]
