A fascinating story so far.

This is a really interesting story. Arthur is like a thousand times more interesting than that bland emo Arturia.
I’m happy to see more and more stories with Arthur.
Also, I really liked your iteration of Scathach. I specially love the relationship she shares with Arthur. I think in cannon to, these two will have the potential to be great friends due to similar sense of respect towards knighthood and it’s values.
Arthur and Irisveil’s relationship is really cute to. ‘Unrivalled beauties’ is an really accurate description of Arthur and Iri.

For the longest time, I've been trying to find Prototype Saber/Arthur Pendragon stories, so it came as a surprise to find your story. So far, its been a rehashing of canon with a few changes so far, Kirei summoning a caster, Scathatch being summoned instead of Diarmuid, Gilgamesh being genderbent, etc.

With that being said, it seems odd that Saber seems a bit cold or at least distant towards Iri towards the beginning, seeing how in most depictions so far, he was polite and friendly to his summoner, I can see the same canon coldness with what Arturia had with Kiritsugu, but I can't really see it with Iri?

Most people reviewing are also assuming that Berserker is Prototype Lancelot, maybe, I've been researching a little bit and either the identity of Beserker, who if I believe is Sir Ironside based on his armor, is either Percival, Gawain, or like I said, earlier, Lancelot.

I can't really comment on anything so far except a few errors I saw, I'm hoping a much detailed relationship between Arthur and Scathatch, considering there both some of my favorite characters. I'm not to harsh on critiquing considering its still the beginning and I'm already sure the butterflies and changes to the initial canon of Fate/Zero will be shown soon, with Assassin having a different master and such.

That said, I really hope you continue the story, its obvious your putting a lot of effort into this and I hope this story gets traction, have a nice day!

I was excitedly waiting for ch 4 and I’m so glad you delivered! I really loved this fic—I love your Arthur, his relationship with Irisviel, and overall I think you’re just doing a very good job with this F/Z AU. I also loved how Iskandar is doing some sort of a running commentary during Gil and Berserlot’s battle, it does sound like something he would do. I also appreciate the excerpts from Proto, it’s great.

Thank you for writing this, I’d be looking forward to the next chapter!

Some errors aside this is a good chapter.

Ah after a long time this story finally updated, thank goodness I thought it was dead. I would like to see a love triangle between Saber,Lancer, and Archer if it's possible Xd. Also is this excalibur the proto version or the anti fortress one?

Wow this got update, nice. and it's good that you are still updating this fic. i'll be looking forward to the next chapter.

I'm glad you updated! Looking forward to the next chapter!

This has been a fascinating story to ready keep up the good work!

Yey i want to see more of Gil fem there is not much fics with she or Arthur so am al glad to read this.

Fate zero es in factbmy favourite Fate serie so i like this so much! Is hard see Arthur in this universe. I think that the story can be more interesting with him in middle of this battle.

You finally updated after 3 months, I'm glad you returned since the potential of this story is really good. I hope you post the next chapter soon.

Proto Arthur is the most nicest guy in Fate series. He is very loyal and a great Cook. 10x better then Arturia Pendragon.

Great start

Fem Gil would be pretty interesting, don't see enough of her in my opinion.
