Berserker
Both members of the Matou clan currently present in the house's basement stared at the Servant that has just been summoned. Apparently, the heroic spirit that Kariya had summoned for the Fourth Holy Grail Was a high-school girl. And she was a Berserker of all classes.
This girl had light-brown, almost blonde hair and amber eyes, both of which were quite uncommon among the Oriental people, but her skin so pale that she could be easily mistaken for a vampire stood out even more. Her clothes consisted of brown knee-high boots; short deep-blue skirt; white blouse with a blue ribbon bow tie; and an orange cardigan – all in all, it was mostly a generic set of school-girl clothes and not something a one could expect to be a heroic spirit's attire.
"And why did I expect a failure like you, Kariya, to summon anything but another failure?" Zouken asked rhetorically. He was about to continue his speech, when the Berserker, who now had a huge tick mark on her forehead, interrupted him
"What did you say, you old piece of shit!" The next moment the head of the Matou clan was hit by a lightning bolt, which originated at the girl's fingertips. The heroic beauty kept shocking Zouken for maybe ten seconds, before seemingly growing bored with this – the master of bug didn't scream or beg for merci or whatever as he was electrocuted. "Let's get out of here. This place is oppressing." And not waiting for her apparent Master to give his OK, Berserker began walking out of the basement also completely ignoring Zouken, who was now dusting his clothes off.
"You aren't the only one who dislikes this house." Kariya whispered under his breath as he hurried after his Servant.

Even though his Servant turned out to be short-tempered, rude, selfish, greedy, domineering, as well as reckless, sadistic and even somewhat homicidal, Kariya, much to his own surprise, managed quite well with her. At least, after he got Berserker to tell him a little about herself and about what she'd wish for once they obtained the Holy Grail. Apparently, for all of her negative qualities, Berserker cared about her younger sister about as much as Kariya himself cared about Sakura – and that was what the two of them had bonded over...

"Two lesser beings claim to be kings, even in my presence?" The new servant spoke arrogantly, as he materialized on top of a light pole. A moment later the very air behind him shimmered into multiple ripples with various weaponry sticking out of those ripples. "Your punishment shall be death." But before Archer could attempt to annihilate Saber and Rider, he was forced to palm away a grenade that being launched towards his head. The grenade had exploded somewhere in the background only scaring the shit out of Rider's Master... "Who dares to attack me?!" Archer – whose true identity was that of the world's King Gilgamesh – asked angrily as he turned to look at the insignificant bug that dared to raise its hand against him.
"I, the Berserker, do, you, golden bastard!" The fifth Servant to enter the battle announced as she stepped out of her hiding spot. While also rearming her weapon and aiming it back at Archer's head... "Now die, Archer!" The second grenade, though, did no better than the first one as Gilgamesh had knocked it away just as easily. In response to this attack on his person, he turned his Gate of Babylon to face her and fired a number of swords and spears.
Once her momentary shock at the Archer's unique way of attacking was over, the girl threw away her grenade launcher and raised her hand towards the nearest light pole. Surprising pretty much everyone who was observing this fight, this Bersreker started discharging a lighting towards that pole from her fingertips. For a moment even Gilgamesh himself couldn't understand why she was doing something seeming so useless when his attack was speeding towards her... But then he saw that all of the weapons he had fired were being attracted to that light pole, with enough force for them all to miss their intended target entirely.
The explosions resulted by the 'treasures' colliding with the ground still threw the strange girl-Servant away, but instead of being killed, she suffered only a few scratches. And once she got back onto her feet, everyone could see an insane, bloodthirsty smile that was splitting her face. That was also the only warning Gilgamesh had before the lighting was thrown in his direction. And, while his majestic armor completely protected him from any damage his body would have suffered otherwise, his eyes still hurt from the blinding electric light that this attack created.
And due to being a bit blinded, the mighty once-King of the world completely missed his intended target when he tried to kill her with another salvo of his 'treasures'... Damn, for an annoying mongrel this strange girl-Servant was surprisingly well at avoiding her death. But, no matter! The Gate of Babylon behind Gilgamesh stretched so with that now literally hundreds of various weapons were sticking out of it. With this much firepower there was no way he'd not annihilate that bitch!
The girl, though, gave a rather-insane smile in response, and the spectral flames erupted from her being. These flames quickly washed over not just the Golden Servant, but over Saber, Lancer and Rider, along with the master of the later, as well.
When the four servants could see something besides the spectral fire again, they found themselves inside a Reality Marble that the schoolgirl-alike Servant had created... They currently stood on an overgrown plaza somewhere in the middle of a desolated suburbs. Somewhere far away skyscrapers could be seen, but those were just as rundown as the three- and four-story houses nearby... A ghost town the size of a Tokyo...
Still, something was off about this eerie place. Even the chattering of crickets and the far-away cawing of crows didn't make this desolated city any more welcoming... Then a light wind blew, raising clouds of dust into the air, as well as carrying a few yellowed from their age sheets of paper. And one of those papers a half-faded but still unmistakable sign of radioactive hazard could be seen.
Before either of the five ...beings trapped within the Reality Marble could do anything in regards to that, the ground under their feet shook as if a giant was walking towards them. A moment later, the ground shook again. Then a building in front of the four Servants and one Master collapsed onto itself as a large mechanical spider rammed through it... The said spider mecha looked like it had suffered quite some serious damage in the past – various wires and strips of metal were hanging loose around the main body. The spider's abdomen also looked like something had exploded inside it. Yet the mecha was moving, powered by the Berserker who stood on top of the machine with multiple wires attached to her fingers, all glowing blue with the electrical power the girl was channeling through them.
"Let's play, bitches!" Berserker yelled as she made the mecha get onto its hind legs. Then the robotic spider slammed the ground, causing it to shatter and quake. In response, Gilgamesh re-opened his Gate of Babylon and aimed an arsenal of various magical weapons at the mechanical abomination that dared to attack him.
"Die." The once-King of the world intoned as he sent his 'treasures' flying towards the mecha controlled by the Berserker. But the spider-thing proved to be much faster and agile than its size led everyone to believe, causing the salvo to miss it completely, destroying a few more building in the background instead.
Meanwhile, the spider raced towards the other three Servants, each step it made quaking the ground. Lancer, being the fastest one, tried to attack, though he wasn't sure how he'd reach the Berserker on top of the mechanical abomination. Any thought within his head, though, were broken into tiny bits when the Irish spearman found himself in the way of the spider's leg's swing. Unable to react fast enough, he was sent flying away into a building. He actually crashed through the wall as well...
Saber, who had been just a little behind Lancer in attacking the mecha, swung her sword at the thing's other front leg, but even with her extreme strength, her Excalibur couldn't really cut the thick armor. It actually got stuck in it. And as the petite swordswoman realized that, Berserker had her 'toy' swing that leg. Saber, though, wasn't thrown away like it happened to Lancer, but only because she was holding onto her sword for dear life.
Suddenly the the mechanical spider went all dead as the girl in control of it suddenly jumped off. A moment later it was blown to bits by multiple weapons that rained upon it from Archer's Gate of Babylon.
"Tch!" Gilgamesh breathed out, annoyed by the mongrel's unwillingness to die when he had ordered her to. At least he had dealt with that disgusting mechanical abomination she had been riding upon. And since this time he really hadn't held back, he managed to wound the girl even it he didn't land a direct hit on her. It meant that she would not be able to escape from his next attack... With that thought in mind, the Golden Servant shrank the Gate of Babylon – there was no need for him to waste that many of his treasures on this mongrel girl.
But before he could finish her, the Reality Marble shattered and he found himself a couple of feet away off the top of the light pole he had been standing upon when Berserker had caught him within that strange world of hers. So surprised by this, Gilgamesh barely reacted to the lack of support under his feet in time: were he even a moment slower, instead of gracefully landing on his feet, he'd have fallen on his ass. Quickly opening the Gates of Babylon to their limits, he was about to atomize the bitch, but before the first weapon could completely leave the Gates, the girl finished astralizing and completely disappeared, and the explosions from the Gilgamesh's attack couldn't harm her at all...

While Kariya had been quite angry and Berserker for using so much of his quite limited prana, in the end he just had her promise to be more thrifty in the future. After all, even if she had failed at eliminating Archer right now, she still managed to take down Rider: her Reality Marble had left his Master dying from radiation sickness within mere eighteen hours from the battle and with how honorable his Servant, mighty Iskander, was, he didn't seek out another master for himself, thus fading away once his prana reserves ran dry.
And from what the young Matou was able to gather through his bug familiars, Lancer and even the Golden Archer himself seemed to be affected quite badly by their time within the Reality Marble as well. And while he was unable to spy on Saber, he could guess that she wasn't faring much better than the other two knight-class Servants...
While this strange Berserker was from what the old bastard Zouken had in mind for him to use in this war, he was sure that the two of them will be able to obtain Grail. And then he will be able to save Sakura from whatever corruption the head of the Matou clan was defiling her with!

Noble Phantasms:
Coppelion doll: C++, passive, support. A permanently active Noble Phantasm. As a Coppelion, Kanon is completely immune to radiation of all types; she has enhanced toughness and passive self-healing, as well as a slightly-superhuman strength. Furthermore, since she was gene-spliced with an electric eel, Kanon has a number of electricity-based powers, including but not limited to: discharging powerful electric blasts, creating electromagnets and sensing electric currents in living things in a wide range. Due to the damage her electric powers do to her own body, Kanon is unable to feel pain or tactile sensations. And as a Coppelion, she is unable to conceive.
The queen of the ghost town: B+, offensive, anti-unit, anti-army. A reality marble Noble Phantasm that manifests as the endless desolated suburbs of contaminated Tokyo. Even the most enduring enemy without complete protection from hazards will eventually be killed here... While within this reality marble, Kanon rides a husk of a three-stories tall mechanical spider that she powers up with her electric powers. And should it be destroyed, Kanon can continue fighting on her feet... This reality marble would have been kill-or-be-killed one if Kanon could maintain it for long enough. Alas, she can't support it for long, and tougher opponents can outlast her there. Even then, had they been affected by radiation, they would get minus rank to endurance, agility and strength for 24 hours, while their prana consumption would go rank up for the same duration.
