A legendary king of Britain. Also called the King of Knights.
Artoria is a childhood name and, upon being raised as a king, she began to be called King Arthur.In an age when chivalry had lost its beauty, with a holy sword in her hands, she brought about a brief moment of peace and final prosperity to Britain. A man in historical fact, but it seems that in this world she was a cross-dressing beauty.
Strenght
- Easily flung a stone slab weighing several tons into the air.
Along with her roar, the clump of air pressure—which had the momentum to sweep away an army of thousands and was supported by the release of prana – impacted heavily on the top of the stone slab; the slab, which looked as if it must weigh at least several tons, was easily flung into the air. It completely defied the laws of physics that the slender wrist of a young girl could carry out such a grand feat; this was the godly skill transcending normalcy that only a Servant could possess.

Destroys the surroundings fighting against Lancer
The wind that followed the swinging of weapons crudely severed the lamp post in half. Irisviel could no longer see the movements carried out at such high speeds. She was only feeling the after-shock of the conflict between the two.
The peeling sheet iron on the outer walls of the warehouses was ripped away by the wind from Irisviel’s side as if it was a piece of coiled tin foil. She could not comprehend how the iron can be torn away. Perhaps it was Saber’s sword or Lancer’s spear that brushed against its adjacent hollow space. Apart from that, she could not come up with any other explanation.

Speed
Overwhelms Lancer who trades 100 blows with Archer in an instant
Deflects arrows that can cross four kilometers in less than a second
Passes the speed of sound while fighting Lancer:
The clash between the precious artifacts of legend, driven by strength and speed far beyond that of a human, passed the speed of sound, nearing the speed of light. Observation had long since lost meaning in this momentous battle. Those divine skills, pushed to the limits at the point of this fierce battle, were having a supreme contest between the two.
An unknown number of rounds had been fought; perhaps tens of rounds, perhaps hundreds of rounds. It was simply impossible to determine with a mortal eye. After the lance and sword of the two clashed, they finally separated, and moved away from each other.
By good command of footwork as a Servant, Saber would be able to rival a jet fighter in speed and galloped on top of the water. However, this vast river surface, with no obstacles at all, was undoubtedly the best hunting ground for the black knight who strafed down from the air above.
The bullets pouring out like torrential rain swept behind the galloping Saber, missing her by a hair, and scattered raging sheets of water like the streams of an upward waterfall.
Regardless of the size of the caliber, something on the level of mere cannon shells pose no threat to Servants at all. This is especially so with Saber, whose physical abilities would also her to evade them with no difficulty, and even deflect the shots back with the blade of her sword if she wanted to. However – no matter how extraordinary the Heroic Spirit may be, the 12,000 rounds-per-minute of the pride of America’s General Electric, the M61 autocannon, presented an unmanageable amount of shots. Worse yet, as a weapon carrying the properties of a Noble Phantasm due to Berserker’s prana, a single shot would instantly be fatal.
Durability
Materializes her armor:
Saber cannot dematerialize, but she can materialize her battle outfit and then cancel it. In other words, Saber’s armor is knit out of prana, and it is not material in the present reality like the clothes Irisviel bought.
Very high magic resistance (Most of her stats are lower than usual because Emiya is a terrible Master)
Fights for hours, fearlessly, against Vortigern the Dragon after Excalibur’s light had been almost completely taken:
The battle raged several hours. The throne room caved in, and the dragon summoned dark clouds with its roar and increased its size to great proportions, destroying the citadel in the process. The neck of the dragon manifested, engulfing weapons, corpses, and wreckage of the citadel in its wake.
The King must have known that Vortigern was Britain itself. The Usurper had appeared as the will and avatar of the island. The ruler of a small tribe who drank the blood of a dragon had lost his humanity long ago. The King’s magical power may be great and his holy sword able to burn the land, but all of the island of Britain was the body of his adversary.
It would have been apparent to anyone’s eyes that victory was futile. It was like an ant challenging a person. Once I recovered, I advised the King to retreat while guarding his back. The King like always embraced his fear and looked up into the sky.
Noble Phantasm
- Can create a wall of air
- Strike Air
- Uses wind as speed boost
Without it, Excalibur’s sharpness is increased by almost over 10x:
Higashide: Incidentally, does the sharpness of Excalibur vary when covered with and without Invisible Air?
Nasu: It varies considerably. The destructive power of this golden version is overwhelmingly superior. If the power when in Invisible Air is 80-90, the golden version is about 1000.
- Covers a city and destroys thousands of black creatures
At least as powerful as a nuke as the heroic spirit Karna’s Brahmastra Kundala (which is like Excalibur) is likened to a nuclear weapon with a A+ rank while Excalibur has A++:
■ Brahmastra Kundala: O Brahma, Curse Me
Rank: A+
Type: Anti-Country Noble Phantasm
Range: 2~90
Maximum Targets: 600 People
The Anti-Country Noble Phantasm Karna got from the Brahman Parashurama.
It is a bow if his class is Archer, in other classes it manifests as a projectile. Granted Karna’s fiery attribute, one blow is likened to a nuclear weapon.
It was –
“Ex – calibur!!!”
Light galloped.
Light roared.
The prana, accelerated by the factor of the released dragon, became a streak of light, a swirling and surging torrent that devoured the sea demon together with the dark night.
A silent scream rose within the river water evaporating in an instant, as every single atom composing the body of the giant sea demon that had been the embodiment of terror were exposed to the scorching impact.
-Fate/Zero: Act 10
Can do a quick Excalibur blast that is able to kill Berserker
Avalon – Unactivated, unless Saber’s head is crushed she can regenerate from any wound and negate magical afflictions in the matter of seconds. When activated, Avalon forms a small barrier which displaces Saber from reality and puts her in the world of Fairies. In short it renders any physical attack useless, as well as capable of nullifying all the five True Magics and even Gilgamesh’s Enuma Elish, a dimension-splitting attack. It is unknown exactly how long it can be activated but avalon is a bounded field which means that the field lasts as long as it can be sustained without breaking down from its own construction.
