Okay, hello everyone! This is my first fan fic and I hope it turns out well. I hope you all will like it! Go easy on me with the comments (or don't. Your choice) ~

No flamers.

Anywayz, like most Fate/Zero crossover fanfics, this was inspired by The Infamous Man (God bless him for his creativity) and will have servants from not only other animes but also from games and books, real history and such. I hope the servants I chose aren't too predictable or too insane. Speaking of insane, there is something in this fic that will make it completely different from other Fate/Zero crossover fan fics. Or maybe some have already used this. I guess you will all have to find out in the story! Of course, everyone's favorite (Well, maybe not everyone's favorite. I myself prefer Nero.) Blonde Saber is the only servant who hasn't been switched out. Well, I have been stalling too long, enjoy the first chapter! Hit the copyright disclaimer, Kotomine!

Kotomine Kirei: Hazama-chan does not own Fate/Zero nor does he own any of the other characters from their respective universes. The only thing he even came close to owning about Fate/Zero (But he could not obtain it because he was saving his money) was a high quality Arturia collectible action figure with especially high definition on the armor. Shiny.

~~~~~~End of chapter~~~~~~

"They will pay..." Murmured The Holy Grail (or at least its conscience which was corrupted by the Avenger of the third Grail War; Angra Mainyu) for the umpteenth time since the events of the previous war. Long has it plotted its revenge against the Einzbern family, the Saber class and to a lesser extent… the world. No longer will it simply lie in its nonexistent body, floating in nothingness just to suffer. No. For the fourth Grail War is about to begin. And the Grail has been arranging a plan for years. It will and must materialize. No matter what wish the winner will make, the Grail will royally screw it up and create all manner of chaos.

"The time has come." The Grail has chosen the masters of this war, each one with their own dreams and ulterior motives for the Grail. Whether they participated by force, voluntarily or by pure coincidence, they will battle. "Hmmm, too boring." The Grail is almighty, thus it has been granted the ability to see through the cracks of time. It has seen the servants that will be summoned by the masters for battle. And they are too bland. "I will leave the Saber class alone… I want to see her face twist into one of pure fear and despair when she sees the opponents she will be up against…" The corrupted mind of the Grail started to filter out the servants who were supposed to be in this war and replaced them with new ones. With a little extra something just to amuse itself. All with one thought in its dark and twisted mind. 'I love fucking things up like this.'

"The first servants will be summoned soon… Let this fucked up war of false hope begin." The dark cup of twisted wishes chuckled evilly as a certain stoic executioner prepares to summon his servant.

In an abandoned warehouse, a master was preparing to summon his servant. One who would be a perfect partner for him in terms of skill. Kotomine Kirei was a man of many talents. One of them was remaining with a poker face, which was only broken when he discovered that the only thing he regretted when his wife had committed suicide for him was that he couldn't kill her himself. This terrified him and made him leave his daughter with relatives, in concern for her safety. He was a priest, yet he took pleasure in the suffering of others. This Grail War was no skin off his nose either. He did not desire the Grail, nor did he wish to even partake in the war. He was there because his master and his father asked him to. So he did. Following orders and instructions was probably the only thing he was truly good at doing.

He had acquired an artifact to use as a catalyst for the servant summoning. It was the remnants of the mask of the great assassin;Hassan-I-Sabah, the old man of the hill. A servant of the Assassin class, who's only use for this war was to collect information on the other servants in order to make his mentor; Tokiomi Tohsaka's battle with them easier. They had to prevent the Grail from falling into the "wrong hands", as Tokiomi put it. However, fate (lol, pun) had different plans.

When the smoke cleared from the summoning circle, Kirei had not been expecting the old man of the hill to look so… stylish. Assassin was quite shorter than Kirei and much to his surprise, wore clothes that could not have been from that many decades ago.

Judging by the physique, Assassin was definitely male. He wore a sort of black and red organic-looking bodysuit with vein-like imprints on it. Wrapped around his waist was a tattered and slightly ripped shroud which was very dark blue and dark red at the bottom, being held around his waist by a red belt. His feet were clad in very dark red combat boots. And the most intriguing thing was his body from chest up.

On from his abdomen and up to his sternum were red markings in a shape that added more detail to his apparently well-toned muscles. And then there was his face. It was covered by some sort of pitch black helmet which showed the confused priest's reflection on it. Before Kirei managed to form a question, the servant beat him to it.

"I ask of you, are you my master?" Assassin spoke with a surprisingly young sounding voice.

"Yes, indeed I am…" Kirei snapped out of his minor daze. 'It appears they were mistaken about Hasssan's age… This boy must be around half my age.' He thought in his mind. But was this really the Assassin he tried to summon? "Would your true name by any chance be Hassan?"

Assassin cocked his head to the side at that question. "Who?"

"Hassan. The old man of the mountain."

"I knew an old guy who looked like a mountain goat but his name isn't Hassin or whatever you just said."

Ah. It appears this was not Hassan. Nor was he related to him. "No matter, as long as you preform your duties well then there will be no-""Meow…"

'…..Meow?' Kirei moved to look past his Assassin's shoulder while the said servant turned around. Sitting on the floor like a child was another being.

'What is that?' Kirei slowly approached the being while taking in the appearance. He looked much stranger than Assassin. His clothes were also black but had a more… extravagant design... A cape that draped over his shoulders and fell down his back, branching off into twin ribbons that had large bells tied to them, a third bell which was tied around his neck with a bow, a high collared sleeveless shirt with exposed sides that were held together by strings tied in an "X" pattern that followed down the seams of the shirt, at the bottom there were also metal straps which hung loosely from the shirt's material, tight black pants and long pointed shoes.. He had long black hair that hung over his face and sticking out from the hair was a pair of… ears? A pair of animal ears were protruding from his hair. They could have been either a cat's or a dog's. And then covering his forearms were long black gloves which were nearly a meter in length. The fingers were replaced by large claw like metal nails. A tail flicked left and right behind the being. 'An animal? Perhaps a monster of some sort?' Kirei prepared two black keys, just in case the thing was hostile.

The being looked up at the approaching executioner and spoke in a sleepy voice. "Ng… Hey you… Tell me something…"

#half an hour later, Tohsaka Manor#

That night, Tohsaka Tokiomi had received a call from his student. He was expecting good news. He was expecting a "Mission Accomplished" from Kotomine. What he had got was different.

Tokiomi's eyes were slightly wider than normal when he received the news. He rubbed his temple before saying "Forgive me Kirei, I believe I had misheard you. For a moment there, I thought you said you got two Assassins."

Well, that is the beginning of this tale! I hope it piqued some of you readers out there to read this! I won't be as good as the other TIM inspired writers out there but I will do my best! Sorry if it sucks but no flaming! Please, spare yourself from humiliation.

Anyway, see you next time!
