User blog comment:Artoria's Bike/EMIYA Alter Theory/@comment-29543192-20170113123003

(This is an interesting topic about alters. I must apologize, but I went deep into alters and not just about Emiya. I do return to Emiya, but you must understand everything else I talk about first)

Isn't Cu alter darker than his normal self? There is also Devil Saber, Counter Guardian, who is called but not confirmed to be, Okita alter. She has darker skin.

While Corrupted Ushi does have darker skin, but she was affected by Tiamat's Sea of Life. In a way, it was a forced alteration that might be artificial.

Cu alter was also forced to become an alter. "the twisted form of the Hound of Culann wished for upon a Holy Grail by Medb" This can also be a forced alteration to his actual nature as a heroic spirit by the use of the Grail.

Do know that both have something in common. Their eye color. The normal eye color of an alter is gold, not red. Cu's original eyes are red but Ushi's are blue. Cu alter may have red eyes because of his Berserker class but this is not likely.

Even Emiya alter shows gold eyes in the trailer. Visibly so, as if they want to tell us that he is Emiya alter. I do believe This is Emiya alter who became an alter based on the impression he left onto his enemies.

So you know, color means things in nasuverse. Both gold and red are representatives of the demonic. However that does not mean that all alters are evil. Like Arcueid Brunestud. Her Mystic Eyes of Enchantment are gold.

You might argue that Jalter is an artificial alter because she is "an existence encapsulating much of the corrupted Gilles's biases and feelings". However she is not another aspect of Jeanne. So she cannot be a true alter or an artificial alter, but rather a fictional alter due to her fictional existence.

I believe there to be 3 types of alters:

Original Alters - Servants who were corrupted by Angra Mainyu from the Holy Grail.

Artificial Alters - Servants who were corrupted by another entity or power other than Angra Mainyu (Holy Grail wish, Tiamat's Sea of Mud)

Fictional Alters - Alter Servants who shouldn't exist but do exist due to a strong belief.

Also, the No-name Assassin in Fate/strange fake. She is described as having a "pale skin complexion and golden eyes" This is very similar to an alter. But she couldn't be a Original Alter or an Artificial Alter. Then this line from the TM wikia made sense:

She was known a particularly faithful girl in a certain country whose existence is referred to as "merely a story."

"Merely a story". And who else could be merely a story? A fictional servant like Jalter. But the possibility that she existed as a real person is high. So how? What if her servant form took on her "story like existence" rather than what she was actually like? This would make her an altered version. The difference is that Jalter's story was changed in Gilles's mind. While No-name assassin's story was forgotten.

Her alter part could also come from simply being a Hassan while not getting the seat of Hassan-i Sabbah. There is also her being called a zealot by other believers of the same faith and despised as well. She was a fanatic of fanatics.

Since we are on the subject of stories, let's talk about Jack the Ripper Berserker who is "the embodiment of the mystery behind the legend of Jack the Ripper"

Being summoned with a replica of Jack's knife rather than the original summoned a servant based on their myth or rather stories about them. "Due to the identity of Jack the Ripper having never been discovered, he is "nobody", so he is able to transform into a myriad of different people with the ability to "become anybody.""

He might qualify as a Fictional Alter, but having no form and transforming to any form makes it impossible to call him an alter.

Back to Emiya. This Emiya alter I believe to be a Fictional Alter who was altered by those who feared him. They saw him as a frightening monster who killed mercilesly on the battlefield. Perhaps he only attacked people at night, causing them to see his already dark skin as darker which would explain why his alter version whould take on such an appearance if he is the manifistation of their fears and hatred. He is what they thought to be evil and what they saw as evil created a new Emiya. An Altered Emiya.

Two sides of a coin. One being a savior of lives. One being a reaper of lives. In order to save lives, Emiya took lves.
