Mordred

"You must never remove that helmet."

The child of Arturia's sister, Morgan. A masked knight that came to Camelot with only the recommendation of Morgan and by presenting his awesome swordsmanship became one of the knights of the round table. He was given his sword despite his unknown origins because of his abilities and his straightforward mental chivalry.

In Fate, actually a clone created by Morgan from Arturia. A homunculus, but also a rather complete son of Arturia. Morgan used sorcery to enchant Arturia, who had become a pseudo male, extracted sperm and developed it in her own ovary.

"My son, you have the right to inherit the throne, but for now, hide your status and obey the King. And one day....you will defeat the King and take his place." He bore that obsession of his mother, but before that ambition, was Mordred's adoration of King Arthur.

Being a homunculus, his speed of growth was faster than a human being, and his life span far shorter. Feeling shame at his twisted birth, he was unconsciously jealous of normal people and due to the special innocence that children have, worshiped King Arthur, the "perfect king".

While hiding his dislike of others, he protected the way of the knights in such a way that could only be found in picture books and worked hard daily in being the ideal knight.

But, even that innocence was shattered by Morgan. Not having the slightest feelings of rebellion on him, he was spurred on by Morgan who told him the truth of his birth.

That Mordred was a child born between Arturia and Morgan.

That King Arthur didn't know that Mordred was his own child and that even if he did, he would never accept such a filthy child.

While shocked by this, he was at the same time wrapped in joy.

Despite not being a proper human, he was a child having the same blood as the King. No, as the son of a king that was superior, he should be proud of the fact that he was not human. In name, reality, mind, and body, he was fit to be the successor of the King.

Mordred approached the King with delight. This was because to Mordred, who had no father, King Arthur was the very form of godlike "father".

However, Arturia rejected Mordred very clearly.

"I see. Even if you were born my sister's plotting, you were certainly born from me. However, I will not recognize you as my son nor will I give you the throne."

Arthur hated his sister Morgan. How could the son of that person be accepted. "It makes sense.... I finally understand why my title was the weakest."

Despite how hard he tries. Even if he excels over anyone, the moment he was born from Morgan, the King would look down on him as a forever as a dirtied child.

Because of the love he had up until then had been so great, the hate of the rejected Mordred burned.

As a result, the distrust of the Round Table towards King Arthur spread and the reigns of power of Camelot were seized once Arthur departed for the Rome expedition.

He would become the leader of the rebellion representing the national discontent towards King Arthur, after finally returning after a long and tiresome battle.

Mordred raged, claiming that he hated King Arthur, that he was fit for the throne, but the truth was that he only wanted to be accepted by Arturia. He only wanted to be called "son" by the King.

The final fight.

With both armies dying, the two faced each other on a hill of swords.

"Look around you King Arthur. Your country has ended. Which ever one of us emerges the victor, it matters not. As you see before you, everything is gone. You should have known it would come to this. Had you given to me the crown, this would not have happened. Did you hate me, the son of Morgan, that much?!"

King Arthur emotionlessly replied back. "Not once did I despise you.

There was only one reason I would not give you the throne.

You didn't have the capacity of a King."

Mordred ran forward, driven on by passion.

Defeated in single combat, Mordred collapsed while still impaled by a spear.

"Never remove it before other people." Freed from that mask his mother forced on him, and with a face identical to Arturia exposed, he said,

"....Fa-ther,"

He reached out to touch the King with his blood-soaked hands at least once, but not even that wish was granted as he fell.
