WARNING: This is my first fan fic so don't kill me. I had always wanted to do crossovers and always had ideas in my head but I never bothered to write them down. This is going to be Fate/Zero fanfic but with my own holy grail. I wanted to do my own Holy Grail fanfic after reading other people's interpretations of the Holy Grail war. (Don't worry I won't steal from them). This is will take place during the 4th Holy Grail war. If this becomes popular enough, I might do one based on the 5th Grail war. I don't know if it will take place after this. Note: I only saw the anime and did not read the visual novel. Also you have to be familiar Fate/Zero because I am not going to explain some of the characters here.
Now i present you
The not so holy grail war
(At the Eiznberg residence)
Kiritsugu is have fun with his daughter IIlyia outside the mansion looking for pine nuts. "Look daddy, I found one!" "Good for you" replied Kiritsugu. Irisviel is in the mansion looking through the window, smiling as her husband and daughter is playing outside. However they are called back by the head of the Eiznberg family, Jubstacheit von Einzberg.
(Inside the mansion)
"Do you have it?" Said Jubstacheit. No replied Kiritsugu. "Unfortunately the transporter got into a car crash and it got destroyed." Damn it! Cursed Jubstacheit. "How are we going to find another servant at this point!?" What they were talking was Avalon, the artifact that was needed to summon the servant they wanted. Or really what Jubstacheit wanted. What Kiritsugu said to him was a lie. Avalon wasn't destroyed at all. He told the guy transporting it to take it back to the warehouse to hide it. He did this because he didn't want King Arthur as his servant. Despite her being one of the most powerful servants, however since its King Arthur, you would expect a holy knight to have these 2 things: Honor and Chivalry. Kiritsugu was opposite of those. He would do anything to win, even if it's low. King Arthur wouldn't sit well with that so he figured he needed a new servant. "Don't worry. I got a replacement" said Kiritsugu. "It better work" replied the headmaster. It was a grey disc with 3 knobs on top. It happened to be with the guy that was transporting Avalon. He found it in a black market. It was not some toy or brand so he thought it be of some interest to Kiritsugu. As he gave it Kiritsugu, he left. Little that they know, they were being watched. Back at the mansion, Kiritsugu placed the disk on the circle on the ground that he prepared earlier. Illyia, Irisviel, and the headmasters are all watching as he said the chant. Suddenly the circle started to glow. Then in an explosion of light, the servant appeared. It was a girl who looks a couple years older than Illyia. She had long black hair. She had the disk on her wrist. The headmaster was baffled at this. Kiritsugu looked at her and noticed something about her. It was hers. They are not like any other child's eyes he seen. Hers looked dead. As if she had no soul. The girl looked at him and said "are you my master?"
(Later that night)
The man was at the warehouse like he supposed too. He was eating McDonalds and watching TV with the crate containing Avalon. As he watching TV, the lights suddenly turned off. The man groaned. "Does he ever pay his electrical bills?" As he was about to get up, he heard a loud thud behind him. He slowly turned around just to see a shadowed figure. Before he can scream, the figure grabbed him by the shirt and yelled "WHERE IS HE! "The man replied "I don't know who you're talking about!" "THE MAN YOU MET TODAY!" said the shadowed figure. "Kiritsugu? What do you want with him?!" "ITS NONE OF YOUR BUSSINESS!" said the shadowed figure as threw the guy across the room. The lights turned back so the man can see the figure now. As the man tried to get up he said "You're- "before he can finish saying it, the figure interrupted and yelled "I'M BATMAN!" Batman went towards the guy and picked him up again. "If you don't help me, I'll put you in Arkham Asylum! The man agrees to cooperate. Batman dropped the man and goes the crate containing Avalon. He opens the crate and sees it. Batman thinks to himself, "What does he want with this?"
That was my first chapter. I hope you guys liked it. I would like some constructive criticism so I can improve this story.
