A small corollary before we start: there has yet to be a division between Fate/Zero and Fate/stay night fics in Fanfiction.net. The yardstick that if it uses Fate/Zero characters as the main driving force of the story, it belongs here. If it crosses with Fate/stay night, please note so.
Well then, with that out of the way... Proof that the remaining 10% is worth dying for here, provided you don't die when you are killed:
These are recommendations made by Tropers for Fate/Zero fanfics, all of which have to be signed to stay on the page. After a few samples, you will be able to judge whether you might be interested in the 'fic, based on who recommended it. No-name recommendations will be zapped. Nobody would back up the rec.
Discussion of the recommendation is welcome on the discussion page. As such discussion is important, do remember to add the discussion page to the watchlist, if need be. You can also add to the current recommendations if you want. You can do it by leaving a review, but please make sure it is substantive, or if you do not wish to leave a review by simply adding your handle to the recommended by line. Refrain from posting Conversation in the Main Page though; that goes in the discussion page.
Do warn when a fanfic may head into non-canon territory. Some people just don't like it, and as we all know, Shipping is Serious Business.
Add new examples at the bottom of the section, please. Oh, and definitely Needs More LovingWiki Magic.

Comments: Ongoing For Want of a Nail story based on switching around Servants, focused primarily on Waver and Lancer.

Sypnosis: Taken from the summary provided: Chiron always said thereíd be legends about him one day. He hadnít thought thatíd result in him fighting to the death with other Heroes, though. Percy Jackson and the Olympians/F/SN.
Comments: Thread 2 can be found here, and the third here while the current one is here.
Synopsis: Author's Summary: Years after his parents survived Heaven's Feel, the son of Kayneth and Sola-Ui finds himself in a different sort of supernatural tournament. But can he survive superpowered alien females, scheming businessmen, and his own partner's urge to strangle him?
Comments:Somehow, Kayneth Archibald El-Melloi and his wife Sola-Ui survived the fourth Heavenís Feel ritual. Their son, Meriwether, seems like a chip offtheoldblock when he travels to Japan to research the Fourth War. Unfortunately, his short layover at Shin Tokyo takes a little longer than expected when he accidentally wings Benitsubasa and gets dragged into the Sekirei Plan. Benitsubasa soon finds to her disappointment that her Ashikabi has lived a rather...shelteredlife. Not that this will stop our protagonist from making the Sekirei Plan a whole lot bloodier...
Synopsis: The Holy Grail War is taking place in Fuyuki at the same time Kallen's resistance is stealing CC. When Lelouch protected that purple-haired girl from the fighting between terrorists and Brittanians, he didn't think he will be able to seize an extraordinary opportunity. Lelouch, as Master of Lancer, will try to grasp this wish with his own hands and to destroy Britannia. And doing his level best to put some more 'war' in the Holy Grail War.
Comments: A newborn fan fiction who shows great promise. Some original flavor, good characterization, good use of drama, and really well-paced action.
Synopsis: All of the sudden, seven girls among the cast of Yuru Yuri found themselves in control of the seven Servants of Fate/Zero. Everyday life continues more or less as usual, but will it last?

Comments: Warning for NSFW danbooru ads! Well, this is an excellent series with good pacing and significant volume. The melding of the universes could be smoother, but it suffices. It is Lighter and Softer on the Fate/Zero side, but things do take a bad turn midway...
Synopsis: Kotomine Kirei is a troubled man that only participated in the Holy Grail War to serve Tohsaka Tokiomi and meet Emiya Kiritsugu. In order to do both, he attempted to summon Hassan-I-Sabbah as the Servant Assassin. The Grail heard his plea and instead gave Kirei a rather... unorthodox thief. Gilgamesh better keep his Gate of Babylon locked at night...
Comments: It's about time the Lupin III series got some love. Not only does this fic keep Lupin in character, but it also keeps the dark elements of the first and most recent Lupin anime along with the matureness of Fate/Zero. If anyone is a true Lupin III fan, this fic is for you.
Synopsis: In a war where the good must fight each other only the one who fights hardest will survive! Every Servant is a Rider, summoned from the throne to heed the call of the Holy Grail. Some fight for themselves, some fight for others and some don't need a reason. The Holy Grail is filled with many heroes, many of them are Riders.
Synopsis: The Grail is bored and decides to spice up the 4th Fuyuki War with different servants than the Masters intended... save for Kiritsugu's Saber. Berserker is vocal and wants to fight, Archer's a pacifist, Caster is disturbed rather than disturbing, Lancer is a timid kid in a suit, Rider thinks he's the coolest servant around, and Assassin casually demolishes the fourth wall by asking if he was in "the Visual Novel or the anime" the moment he's summoned. No one knows what to expect from these wild cards, not even their own masters.
Synopsis: Instead of allowing fate to run its usual course, the corrupted Holy Grail decides to mix things up a bit. This one action will throw the Fourth Holy Grail War, and fate itself, into utter chaos. More directly inspired by The Infamous Man's "Fate: Zero Sense".
Comments: Not the first fanfiction where every Servant but Saber is replaced, but it is still an enjoyable read.
Synopsis: Once again, the Grail decides to mess with fate and summons some new Servants. Assassin's scary intelligent, Lancer's more than eager to fight and break things, Berserker's sane and actually the nicest of the bunch, Caster's a hot head in personality and power, and Avenger likes to take enthusiastic walks through the woods at night. Inspired by The Infamous Man's "Fate: Zero Sense".
Comments: Slightly subverts the usual formula of replacing the Servants by keeping not only the canon Saber, but also the canon Archer and Rider. The Masters and Servants get along rather well and the confrontations are both very similar to the canon at times and yet unique. An interesting read.
