A/n: Well you guy sorry for the long delay for the first chapter of my improved welcome to Rapture. So without further ado here it is. I don't own Bioshock and Percy Jackson series along with Heroes of Olympus. They all go to their respective owners. Bioshock goes to Irrational Games while Percy Jackson and the Olympians and the Heroes of Olympus go to Rick Riordan.

*Side note: This story would contain some if not several anime references or scene and skills this type of things, I do not own. They were only use for humor and some comedic effects also added for action effects. This includes breaking the 4th wall

Chapter 1

Yandere unleash and my fight against mother earth

-3rd person POV-

The final chapter of the upcoming 2nd giant war is almost coming to a close. The Demigods of both Greek and Roman decent has set their difference aside for their survival. The seven chosen demigods from both camps are now nearing their final battle. They are now at the foot of the old Mount Olympus, where the final battle will take place. The two camps made a truce as Nico Di Angelo and Reyna brought the Athena Parthenos preventing Octavian's plan in killing all the Greeks .But there is a problem the seven prophesized was missing one member. This member was the one who connects the two camps, the person who had saved their parents thrones. His name is Perseus Jackson, defeater of Kronos, bane of monsters, sailor of the sea of monsters, Savior of Olympus and many more. The Gigantes, Gaea's children, wanted the daughter of wisdom as the sacrifice for the revival for their mother but the Son of Poseidon instead pushed the daughter of wisdom, took the blow, and taken captive instead.

Now the seven prophesized demigods are located under a tree overlooking the battlefield, as they plan for their rescue mission. The one in charge of the said mission is no other than Annabeth chase, daughter of Athena and girlfriend of the savoir of Olympus Percy Jackson.

"How are we going to save Percy?" Frank asked as he looks at the army of monsters in front of them

"We have to save him, if we fail he would die and the fate of the entire western civilization will go with him. Including us, our parents and everybody that we care would be dead." Annabeth said as tears well up in her eyes

"Don't worry Annabeth we would save him." Hazel said as she wrapped her arms around the girls shoulder

"Yeah, we would save him right you guys?" Piper asked the rest

"Hades yes we are going to save him." Leo said as he ignited his hands

"I am in if it involves saving our friend." Jason said

"Yeah!" They all shouted par for Annabeth who was thinking of a plan on saving her boyfriend

"Hey Annabeth, do you have of plan of action in for saving your seaweed brain?" Thalia asked her longtime friend

"Of course I do, you might have heard this from Percy but like I always say Athena always has a plan." Annabeth said

-Percy's POV-

Gods my head hurts like Hades. Try having a full-grown Cyclops tap dancing on your head then add several hammers pounding on it, gods it hurts so much. I tried to get up at least on a sitting position and found myself bound by several pieces of rope.

"Ah finally our little celebrity finally awakens." Prophyrion said

I tried to speak but I noticed that I cannot, which my mouth was gagged by some cloth. Which I was trying to say was "WHAT IN HADES DO YOU WANT WITH ME!" but what came out was a muffled sound.

"What was that here let me remove that gag of yours." He said as he walked towards

When Prophyrion reaches me, he then grabbed my head and the gag in my mouth before yanking it off and punching me in the process.

"What's the matter? Did I hurt you little hero." He said to me

"Oh, go fuck yourself you prick." I said to him when I got my bearings back

"Oh, this one is feisty I like that." Said a new voice

I look towards the sound of the voice and I think I nearly fainted or I became as pale as a ghost did because the person in front of me was Gaia. Well in a form of a teenager that is I thought, I mean she looks like one of Lady Demeter's children but with a huge difference in appearance. She has the chocolate brown hair, forest green eyes and slightly tanned skin. She was also wearing what appears to be a toga and sandals also she was revealing a lot of cleavage.

"Like what you are seeing." Gaea said

If Annabeth were here she would had probably ripped Gaea apart since she is hitting on me.

"No, and if you must know I have a girlfriend thank you very much." I said

"Well here is the thing though, you don't a have a say to this." Gaea said

"You will be my new husband and nothing will stop me not even that spawn of Athena." Gaea said

'Ok that is just fucked up' I thought I mean my great grandmother wants me to marry her. Hades no I am better off marrying Aphrodite than Gaea, even Medusa is better than her.

"No, just no." I said

"Well, time for your nap. You need all your energy later my soon to be husband." Gaea said before kissing me on the lips forcefully then sending me a powerful punch in the case rendering me unconscious.

-Line Break shotgun-

-3rd person POV-

As the seven demigods are making their way towards the throne room of the original Mount Olympus, they came upon a group of monsters that were guarding something.

"Hey Annabeth checked this out." Leo said in a hushed tone and pointed at the group of demigods who appears to be held captive, judging on how tattered their clothes are.

"Let's go free them, maybe Percy is one of them." Jason said

As the remaining, seven along with Thalia and Nico made their way towards the captured demigods. They all managed to get a good look on who they are. They were no other than Luke Castellan, Charles Beckendorf, Silena Beauregard, Lee Fletcher, Castor and Zoe Nightshade.

"It's impossible, how in name of Gods they are here." Thalia said

"I don't know but we have to rescue them they might know were Percy is." Annabeth said

"Right, I bet you have a plan right?" Nico asked Annabeth

"You bet I do." Annabeth said

While the seven plus Reyna, Thalia and Nico starting to set the plan in motion to save their friends. Little did there enemy captors knew that there was a war raging on the ground near the foot of mt. Olympus.

"Hey, ever wonder why we're here?" one of the captors asked its partner

"I don't know. Probably some divine being wants us here and watch over this world as it crumbles into nothingness." The other one said

"No, I mean why are we guarding these unconscious demigods rather than joining the battle." His partner answered

"Oh, I thought you were talking about…SON OF A BITCH!" the other captor said before its head was sliced off and disintegrating to dust

"WHAT IN THE ACTUAL FUU…..ACH?!" the last captor said before disintegrating along with his companion

As the monsters disintegrated into dust, the remaining hidden demigods then revealed themselves and cut the prisoners loose.

"Thalia, Reyna and Nico could you guys watch over them while we try to rescue Percy from Gaea's clutches." Annabeth said

The trio nodded as they tended on the captured and demigods as the remaining seven ran off towards the throne room of the original mount Olympus. When the 7 demigods left the captured demigods were slowly getting their bearings the first one to get his bearings was Zoe Nightshade.

"Woah, easy there Zoe." Thalia said as she helped Zoe get in a sitting position

"Where am I?" She asked

"Safe from Gaea and her goons that's what." Reyna said bluntly as she scans the area her sword at the ready

"Gaea?" Luke spoke this time

"We will explain in later time there is a war going and we need to help the gods." Thalia said

"What war?" Zoe asked

"Oh trust me it's a very long story but now all of you must rest." Nico said

-Line Break-

When the remaining seven, minus Percy, arrived at the throne room of the original Mount Olympus what they found surprised them. In the middle was Percy bound and was wearing only a toga and sandals.

"Percy!" Annabeth screamed along with the rest of the seven

As they tried to ran towards Percy only for them to be held down by an unknown force. Leo face planting, along with Jason and Frank, on the floor as for the girls they were all in a kneeling position. They all tried to move but only to fail badly.

"My, my well this quite a surprise." a very familiar voice said

The seven all faced the sound and saw Prophyrion standing there smugly as he watches the demigods fail on their attempt on getting up and attacking him.

"Fight us you big piece of Minotaur dung!" Leo said

"My, children like you should not use those kinds of words." A new voiced said

Only for them to see a teenage girl around there age and was walking towards their direction. She then suddenly stopped then walked towards a bounded unconscious Percy. When she reached the hero of Olympus she then knelt down and kissed him full on the lips. This of course invokes the wrath of a certain daughter of Athena. This wrath was converted to a power that can only a yandere have. If this was an anime show one could say a dark aura was coming out of a certain daughter of Athena. This change of course was seen by Prophyrion which was slowly moving back as he notices the restraint holding the demigods slowly disappearing.

"Um, mother I think you should stop doing that." Prophyrion advised her mother

"Not right now son, see I am flaunting my new prize and soon to be husband." Gaea said without looking at him only focused on the demigod son of Poseidon who was still sleeping for some unknown reason.

"Mother I think you should look back now." Prophyrion said as he slowly summoned his weapon waiting for a shit storm to start.

"Oh don't be such a pansy my child the demigods won't be able to…" Gaea said in mid-sentence as she turned around only to see the demigods free but were moving slightly backwards from the daughter of Athena. As the daughter slowly got up, her hair covering her eyes, she was suddenly laughing uncontrollably like a maniac while slowly posing like that one pose on a certain anime called Mirai Nikki .She suddenly unsheathed her bone dagger courtesy from her time from Tartarus.

*Insert Mirai Nikki - Battle Theme, theme song for Annabeth*

"Oh I can't have that, Percy is mine and mine alone." Annabeth said as she suddenly lunged at Gaea

As the two duked it out Percy started to get up and the first thing he noticed that he was wearing a toga. So like a good magician he suddenly disappears and got change real quickly before anyone can notice and come back. After five minutes he manages to get changed into a more comfortable clothing mainly a black under shirt, black boots, a black cloak, black fingerless gloves and a black sword on his back.

"Um Percy, where did you got that Kirito outfit from?" Frank asked who manages to watch the anime show before this entire prophecy

"Oh, you mean this thing? I found it inside the box over there." Percy said as he pointed a very convenient looking crate with Japanese writing on it near Apollo's original throne

"Percy before you go all out otaku on us would mind helping your girlfriend?" Piper said as she was helping Jason up

When Percy saw Annabeth fighting Gaea, he knew to better stay away. He knew so well that he should not let Annabeth watch that anime. And now here is the result of it, he made her girlfriend a Yandere, though it's better than having to marry Gaea, her great grandmother which he shuddered from the thought of it.

"SWEET MOTHER CHAOS!" Gaea screamed as she evaded an axe wielding daughter of Athena as she tries to behead her.

'Where in Tartarus name did that girl got that axe?' Prophyrion thought as watches his mother evade the craze looking daughter of Athena

"You know what fuck this shit." Jason said he then charged at Prophyrion

Percy then draw riptide along with the black sword on his back then charged at Prophyrion along with the rest.

"NOBODY EXPECTS THE SPANISH INQUSITION!" Apollo barged in first in the throne only to watch a fight that might as well came out from an anime show. When the Olympian arrived they practically have their jaws on the floor.

The fight was weird in the sense because the older Olympians were watching their grandmother was being chase by the daughter of Athena with an axe in her hand while the remaining seven was fighting Prophyrion. Apollo and Hermes were currently looking at the black clad swordsman and knew it was Percy but there were two things running in their minds.

'How in Hades did he got that outfit?' Apollo thought as he suddenly has the urge to cosplay as an anime character for the fight.

'Oh shit I forgot to deliver that to Apollo.' Hermes thought

"I have enough of this." Gaea said as she suddenly disappeared only to reappear beside Prophyrion and sending a power blast sending the demigods flying towards their godly parents only for them to catch them.

"Gaea surrender now, we have you surrounded!" Zeus thundered

"Never, also nephew please don't use those lines." Gaea groaned

"What?" Zeus asked not even sure what her grandmother was trying to say

"Screw this." Percy said and charged at Gaea bring swinging Riptide, the black sword was broken earlier when he swung the blade at Prophyrion. Apparently the blade was not made of metal but instead it was made of wood. He was expecting it to be metal but of course he forgot that its purpose was just a prop.

When Percy swung Riptide it was intercepted by Prophyrion with his own weapon and soon the two clashes. Upon seeing the two fighting the rest of the Olympians and demigods soon joined the fight against Gaea and her son. Percy was soon joined by Jason and his father fighting against Prophyrion. Prophyrion manages get a lucky shot with his weapon and sent crashing to Gaea who was pulling a Gilgamesh gate of Babylon attack. Percy got back up and started to fight Gaea instead. As the two clashing the rest of the Olympians tried to help the son of Poseidon to no avail as they try to get close they would just be swatted by Gaea and her Earthly weapons. When the two weapons clashed Percy was smirking slightly while Gaea was glaring very hard on the son of Poseidon that is when a scream pierced the tension. When Gaea looked at the direction of the scream she was filled with rage as she watches her son turn into nothing but dust and his essence returning to Tartarus. In her rage she unleashes her semi-divine form. (A/n: this form, I thought about, is basically that all immortals are capable in tapping in their divine form getting only a small amount only for them to access their powerful weapons, armor and powers. Almost like a noble phantasm in Fate/stay night)

In a brilliant bright light, when the light died down the saw Gaea wearing a bronze armor, with a leather skirt, a shield strap to her back and a sword sheath on her hip. This time Gaea opened her eyes she then focused on Percy eyes fuel with anger. Percy then raised his blade for him to block a sword only by mere inches from severing his neck. Only for him to be kicked by Gaea towards Annabeth and the two of them ended up crashing on top of each other, Gaea then decided to beat the living Hades of the remaining Olympians in her enraged state leaving only a bloody mess in the throne room. Annabeth and Percy got up only to see their friends and family in a bloody wounded mess and Gaea standing in the middle.

"WWWWWRRRRRYYYYYYYYYYYYYYYY!" Gaea said posing like Dio Brando

"Hey Annabeth you okay?" Percy asked

"Yeah I am okay." Annabeth said as she got up she notices a very well placed short sword right in front of her

The sword was celestial bronze but shape into a more of a French Rapier than the standard issue Greek sword.

"Arigato Assassin-sama for this gift you gave me today." Annabeth said as she unsheathed the celestial bronze rapier and placing her dagger back in its sheath

"Um, Annabeth who are you talking to?" Percy asked

"Oh, just the author for placing this very convenient looking sword right in front of me." Annabeth replied

"Okay…" Percy said while having an anime sweat dropped.

"Are you going to stand there or what?" Gaea asked placing her hand on her hips tapping her foot impatiently

Annabeth decided to shrug off the unusual conversation before taking her combat stance. Percy of course lunged at Gaea first without even thinking what she is capable of. Gaea blocked Percy's sword swing with her shield and pushed him and slammed her shield harder making Percy face plant on the floor. Annabeth then lunged at Gaea with incredible speed trying to impale Gaea but only for her to block the attack and retaliate by swing her spear at her. Annabeth manages evade the attack by ducking and then lunged at Gaea hoping it will distract her till Percy manages to flank her. This of course was true enough Percy manages to flank Gaea from her Right and swung at her which only grazes her Armor which only made Gaea angrier at the duo. Gaea then threw her shield at Percy while swiping her spear and sending her flying to Percy's side. The duo then stood up and saw Gaea drew her sword now.

"This is where it ends now demigods." Gaea said making a stance raising her spear slightly in her left hand. (A/n: basically Hilde's stance in soul calibur)

"Alright let's end this fight." Percy said taking his stance

The two stared at each other until a disembodied voice can be heard throughout the entire throne room.

"THE FATE OF THE WORLD NOW LIES IN THE HANDS OF THIS TWO COMBATNANTS. GO ALL OUT AND GIVE IT YOUR ALL FOR ONLY ONE CAN CLAIM VICTORY IN THIS ANCIENT LAND!" the voice said

"FIGHT!" it continued

*Insert a fighting music here*

Then within a blink of an eye Percy then charged at Gaea with speed that can rival Hermes, but he was not that fast. Gaea responded by thrusting her spear only to be blocked by Percy's sword in which Gaea then swung her sword. Percy then jumped back to evade the attack only for him to be hit in the gut by the blunt edge of Gaea's spear. Making him stagger a bit this opening was utilize by Gaea in which she thrusted her sword hoping to stab Percy. This attack was countered when Annabeth switch with Percy in which she parried and manages to get a hit on Gaea but only giving her a minor scratch. Gaea then swung her spear at Annabeth knocking her back and sending her flying beside the fallen seven and Olympians as they slowly got up. Percy watching the love of his life getting hurt made him very angry. With a bit of in human speed Percy manages to close in the gap between him and Gaea. There Percy made a sweep using his sword only to be blocked by Gaea's spear then she swung her sword for an overhead arc in which Percy dodged by rolling to the side. Percy then swung his sword and manages to catch Gaea's spear and sever it in half, leveling the field to him. When Gaea notices her spear was spit in half in which she threw the other half of her Percy only for him to side step and letting the spear fly by him. The spear that Gaea threw impaled my mere centimeters from Ares's family jewels. Percy then used the hilt of his sword hitting Gaea's armor and making a dent to it. She tried to block it but failed and which allowed to Percy to dent her armor. The dent soon became a crack in which Gaea's armor soon shattered. "ARMOR BREAK!" the disembodied voice said making the entire fight some sort of fighting game. They ignored it and continued on fighting with the advantage to Percy. Gaea decided to pull out a trick that she knew might tip the scale of battle. She brought her hand and raised it making the ground where she was standing rise up a little. This caught Percy by surprise only for him to be hit by the raised platform in the gut before the platform stopped abruptly and sending the hero of Olympus in the air. This opportunity was utilize by Gaea when she lunged at him in which she swung the blunt edge of her sword at Percy and in which sent him sliding to the center of the raised platform. Percy then stood up raising his blade preparing for another attack only for him to roll to the side when a rock spear came down trying to impale him. Percy then looked at Gaea and notices several rocks have formed into spears and it was aiming at him.

Gaea then launches all her rock spears at Percy in which Percy started to run towards Gaea while evading the projectile weapons in the way. There were been several close calls from Gaea's attack but thankfully Percy manages to get close and manages to stab Gaea in the gut. Percy then pulled Riptide out and then sliced Gaea's sword arm off before kicking her off the platform. With that Gaea then fell down from the raised platform making a loud thud that echoed throughout the throne room. The entire occupants of the throne room looked at Gaea's fallen body and then towards Perseus form standing on top of the raise platform in the middle of the throne room.

"FATALITY!" Leo shouted in the same way the disembodied voice said

Everybody and the disembodied voice then looked at the young Latino boy like he was some sort of deranged lunatic from the land were Mortal Kombat exist. The awkward silence lasted for five minutes till Percy decided to break it by coughing a little from the top.

"Okay…Leo that was uncalled for since this is not Mortal Kombat also I did not killed Gaea in a very brutal way." Percy said on top of the raised platform in the middle of the throne room

Gaea who was still conscious rolled to a prone position and looked at the Olympians and the Hero whom beat her. She was so close in winning the battle if not for those damn Olympians, that Spawn of Athena and that handsome son of Poseidon. If she would have won that child of Poseidon would had been hers alone. With her little bit of strength she reached out and made a crushing motion in her hand to make the platform were the child of Poseidon was standing. There was a deep rumbling sound emitting from where Percy was standing and all of a sudden the raise platform was soon crumbling. Percy fell from the place where he was standing was closing was fast on the cold hard marble floor of the throne room. In order to slow his decent Percy started to jump from the pieces of falling debris and holding on to it. Once he reach the right height he jumped of the debris he was holding on and did a combat roll in order to limit the amount of force. The direction of Percy's roll was towards the direction of his demigod friends. After Percy's roll he made a pose while on a crouching position with one hand up in the air and the other on the ground with his head down.

"Show off." Leo muttered

Percy then slowly stood up and looked at his friends and family. He got up and looked at Annabeth with a smile on his face. Gaea on the other hand was not yet finish she made a rock spear and aimed it at the daughter of Athena. 'If I can't have him then neither can you have him.' Gaea thought as she lunched the rock spear and prepared another trick. Percy saw this and pushed Annabeth away and he instead got impaled by the spear. Then the place where the daughter of Athena was standing would collapse sending her to Tartarus if Gaea's spear failed to impale the daughter of Athena. Now Percy was hanging on the edge of the hole that Gaea made, that would send him back to Tartarus. Annabeth on the other hand was holding Percy's hand. Percy on the other hand was sure he cannot hold on for much longer with spear still impaled in stomach and was sure neither can Annabeth support the both of them.

"Annabeth you have to let go." Percy said to Annabeth

"No Percy I will not let go." Annabeth said to Percy

"You know you will not be able to hold the both of us." Percy said

"I will not let go if you go I will go." Annabeth said

"Annabeth I will not let you go to Tartarus again." Percy said as his hand was slowly slipping from Annabeths grasp

"No Percy, please don't let go." Annabeth now begging as she tightens her grip on Percy's hand

"Annabeth please let go…" Percy said still pained since the adrenaline was wearing off

"Percy please holds on a little longer." Annabeth said still struggling on holding Percy

"Goodbye Annabeth and I love you." Percy said as he slipped from Annabeth's grip

"PERCY!" Annabeth screamed as she tries to jump with Percy only to held back by her own Mother

Percy only looked at Annabeth one more time knowing that the love of her life would live. As he plunges once more to Tartarus he closed his eyes accepting his fate but little did he know that his life would shape the foundation of a long forgotten city in the depths of the ocean.
