What if Shirou was raised by...Gilgamesh?
xXx
The armour clad body of the legendary King of Heroes had no problems repelling the heat of the flames that had surrounded him, in the midst of the destruction he had helped create.
Walking through the piles of corpses, and rubble, he nearly growled aloud, nobody could kill his subjects but him! That bastard Kotomine was lucky he was so good at amusing him, other wise he would be dealt with like any other who challenged his reign.
Turning his head, he noted the struggling form of a child, his body covered by the corpse of his beloved Saber's former Master.
Had it been a normal day, Gilgamesh would have simply killed the boy then and there, but he saw something in the boys' eyes, something that had been missing in the eyes of almost every living creature he had come across.
There was power there, and steel of the finest quality.
Gilgamesh grinned, the boy would make a fine subject, and if he proved himself to be as great as the King of Heroes believed he could... Then he would make for an excellent squire.

Shirou bowed in his king's presence; his training in magecraft completed for the day.
10 years previously he had been rescued from the flames by the ancient Sumerian king, and as such, had pledged himself to his service.
He himself held no memories beyond his name, and his experience in the fire, an almost blank slate, moulded into the perfect subject for his King's rule.
As a bonus to the training his king had granted him, the mage Kotomine, had also been teaching him magecraft, after grafting the family crest of the man who had been called Emiya, in addition to Shirou's natural 27 circuits, he had done well in learning the basics but had been unable to grow beyond that, before the discovery of his talent.
The ability to reproduce any sword, any blade, any [I]weapon.[/I]
It was an ability that seemed to be unique to him, and while Gilgamesh would insult and belittle it, he knew that it would be incredibly useful in his service.
"The war for the Holy Grail is about to commence, are you ready?" While Gilgamesh would never admit it to anybody, he was proud of his servant, and glad he had plucked the boy from the fires that had almost claimed him so many years ago.
"Of course, you highness, I am merely looking for the correct catalyst to use in the summoning." Shirou himself knew that the only positions left were for the Saber and Archer class, he was also keenly aware that if he summoned Arturia Pendragon, his king would not hesitate to kill him.
"Then be gone from my sight, and do not return till you have the grail." Gilgamesh knew the boy would be victorious, even without the aid of a servant, the boy had been trained well, and had has magic amplified by the many different elixirs that Gilgamesh held in his vault.
"By your leave." Bowing once more, Shirou left the church, preparing to head into the heart of conflict, and claim the grail in the name of the greatest of kings.

Bah, this one is too short, but, I'm having trouble with the other one, so enjoy this until I can finish it. Or until I get a good suggestion.
