This reaction fanfic (watching), is about Percy Jackson in other worlds, taking the place of characters from other franchises, movies, games, etc.

If you don't like it, I have another Percy Jackson reaction fanfic seeing other characters from other media, without changing them, such as: Justice League, Avengers, Team Avatar, etc.

The parts referring to what is 'projecting':

What is said in the projection or if it refers to a fic, which you have permission to use.

What PJ's Characters Are Seeing and Hearing

To differentiate future characters from their past/present counterparts, I will add the letter F to the end of their first or last names, or use P to differentiate the past/present from those in the future

Hearing and remembering that in the future Percy Jackson would end up falling into Tartarus, darkened the atmosphere again in the throne room of the Olympic council, however some noticed that in what was narrated before the projection went dark again, it was said that the son of Poseidon rejected immortality and instead asked for other favors. This caused curiosity to the gods who noticed that detail.

Zeus rewarding a son of Poseidon?...

It was hard to believe... but what did the narrative refer to with immortality, a blessing from the Gods to continue living?, for what favors would the son of Poseidon change it?

That led them to ask the demigods of the future.

The Romans were ignorant of it, but the Greeks knew but did not know who would explain it, so they turned to see each other. But in the end it fell to AnnabethF and Thalia to explain it.

Few realized that the Fates did not interfere with the explanation by blocking the demigoddesses' voice from wherever they were, however many found it hard to believe.

"Was the divinity offered to him?" said Hecate

"And... he rejected it?" the incredulity was clear in Hebe's tone

"A man... "Did he re-reject it?" said Artemis, which annoyed Rhodes and others.

"Yes," AnnabethF confirmed for the umpteenth time

Meanwhile, the young Percy was receiving various views from the Greeks of his time, from the Romans, Amazons, huntresses; which made him uncomfortable, since he does not like attention

"Then what did he ask for?" asked a curious Hades

Thalia sighed before continuing the explanation, that Perseus asked that Hestia and Hades have a seat on the council, that all the demigods be recognized during their first days after arriving at the camp regardless of whether they were children of the members of the Olympian council or not, that the gods outside the council have their own cabin in the camp, etc.

But Thalia and AnnabethF had to swear on the Stygian that they were not lying. And all those who were not the Greeks of the future, along with Leo and Piper were incredibly surprised, they could not believe that the son of Poseidon would not ask for anything for himself, but for others.

Calypso was surprised and happy that Percy asked that those who did not support the Titans but were still punished by Zeus, be released from their punishment.

The minor gods and their sons were surprised that Poseidon's son asked for recognition for them in the camp. As well as those ignored by their parents who would never have been claimed if it were not for this that also benefited them.

But the Romans were even more surprised by the kind of person their green-eyed praetor is.

While young Percy was amazed by what he did in the future, as well as the rest of the demigods of his time.

For their part, Piper, Leo and Jason, had heard the stories about Percy, although they had found them hard to believe, even now, but with the oaths given by the two demigoddesses...

As for the hunters, along with Artemis, they had the biggest shock of their lives, since the son of Poseidon broke any perception they have about men by rejecting divinity, but by having his way of thinking and distrusting men for so long, It made it difficult for them to accept what they heard, especially the most stubborn ones.

However, the king of Atlantis had various mixed emotions, he was somewhat disappointed or rather sad that his son did not want to be a god, which would cause him to one day die and go to Elysium, but he was also incredibly proud of his son, along with several other emotions. And the rest of the Atlanteans shared to some extent some of Poseidon's feelings, even Kymopoleia was really surprised.

"Idiot/stupid" There were also those who thought that Sally Jackson's son was a fool for rejecting divinity, whether they were gods, legacies or half-bloods

And Hestia was also happy and proud of her nephew, thinking that he would be someone she could bless, maybe even make her champion upon hearing that her nephew is or will be a good man.

...

...

But they were not yet done seeing the different worlds that exist, so they had to continue. However, it took everyone in the Olympic Council room a while to calm down to take in what they learned about the future and Poseidon's son before resuming the screening

He had to be faster, more agile, stronger, more resistant. He had to overcome himself once again day by day, leaving behind his weak self to protect his partner and his desire to return home. He was not allowed to stay on the ground, even if his muscles and bones screamed in pain, refusing the help of water to get used to it. Changing weapons so as not to remain static in a predetermined posture, adapting to the versatility that the hypothetical situation of the place could unexpectedly offer.

"What...?"

"Gods..."

"Ahhh"

"What the Hades..."

"Chaos"

The spectators would have admired, applauded or appreciated the words narrated about Jackson, about getting stronger, but not to desire power, but to help, protect and look for a way home... or at least they would have if it weren't for the fact that they were in total surprise at the level of fighting and training they were seeing.

The blotches that were his opponents gradually became visible, allowing the son of Poseidon to see the faces of others belonging to a historical past that he knew from stories or fleeting sightings. The immeasurable pain told him how real they were, drawing endless crimson lines or purplish bruises on his skin, moistening his hair with sweat to the point that it fell on the bluish-green orbs that conveyed a deep seriousness.

He was barely able to stand, biting his tongue in the face of the brutal attacks that Achilles delivered along with Perseus, denying him access to close range to stop defending himself and go on the offensive. And even if he managed to get it, he was quickly repelled by fast arrows that wounded his legs thanks to the assistance of Atalanta and Chiron, imperatively insisting that he use the deployable shield to contain the avalanche of arrows, as well as the constant tapping of a of a chained dagger manipulated by Medusa Rider.

"Holy Jupiter"

"What the Chaos...?"

"..."

"Oh, my Gods"

The level shown by the Servants, as well as that Percy Jackson, had most of them almost completely stunned, no half-blood, legacy, hunter or amazon could fight like this, even some lesser gods doubted they could do it despite what they are. And those who could express something, their voices came out like whispers or muffled exclamations.

The skill, dexterity, speed, etc. they saw was not something that could be easily attained, only the best fighters that have ever existed in their pantheon could attain.

That Perseus could keep up with several of them at the same time, would stay in their minds, and also made those who still had their doubts about the young green-eyed man being strong in the future, that he could survive Tatarus, face Titans and Giants, diminish those doubts.

Gritting his teeth and closing his eyes to keep his thoughts focused on the fight, Percy Jackson felt his own body scream at him to step aside, immediately after obeying the premonition he saw how sharp claws sank into the ground, precisely where he had previously defended himself, managing to see a white-haired Amazon. For obvious reasons, the demigod rolled back to the ground, perfectly eluding two swords while a third managed to draw a new scar on his right cheek, all before using the shield as a blunt object against Nero Caster's feet, knocking her down and preventing her other counterparts from attacking him further.

"Watch out, Percy," whispered AnnabethP, Grover, and a few others with concern for the on-screen counterpart

But they were not the only ones, Greeks of the future or Romans also did it "Beware, seaweed brain/Jackson"

Because despite the amazement they had they worried about Sally Jackson's son, because of the level of fighting they saw because it was too dangerous, a single mistake and it could be the end of Jackson.

Although the young Jackson in the audience was the most concerned and amazed by what his counterpart could do, who was barely of legal age

Saliva and blood were suddenly spat out when a kick hit the demigod's torso, inflicted by Heracles' generosity, and feeling how two ribs were easily broken, causing him to collide against a pillar found at the end of the room as he desperately sought to recover.

"Heracles!"

"Son of..."

Curses towards Heracles, were said by several members of the public, as well as promises of pain towards this or rather the counterpart of this world.

"Do you give up?" a stoic Gorgon asked from the side next to Gudako, the latter having agreed to Jackson's request to lend him her Servants for a few hours a day for the purpose of training.

"Give up!"

"Don't keep fighting!"

"He can't beat them"

Exclamations could be heard that the various onlookers wanted that Jackson to do, that was more than enough in their opinions, but those who knew the green-eyed demigod best could only hope that their friend's counterpart wasn't so stubborn as not to give up.

"Don't do something stupid, Jackson/Percy!"

Not a word answered the question, the stubbornness of the black-haired man being visible as he stifled an agonizing moan and stood up with even more motivation than before, thus demonstrating himself with the opaque gleam of his eyes, transmitting to the Heroic Spirits the stormy mist of the sea about to explode with fury.

"Jackson!"

"Percy!"

"Seaweed brain!"

Sounds of frustration, anger and annoyance could be heard right now due to the stubbornness of the green-eyed man on the screen.

Young Percy Jackson felt offended by the exclamations made about his counterpart and at the same time agreed with them, since the level of combat, even if it was training, was ridiculously hard.

"Mmh... it seems that he won't after all" sketching an anxious grimace, Medusa Avenger muttered, longing for how much longer the son of the sea was capable of withstanding such training.

Various glances fulminated at the Gorgon, as well as a couple of curses.

As if that sentence had been a clear detonator, Jackson's badly wounded body pounced unexpectedly on an astonished Jason, knocking him out with a blow to the head on the flat part of Anaklusmos' blade, and then leaping to where Asterios stood, holding him by the sinister horn and using the force of thrust in his favor to knock him down thunderously.

Caligula quickly followed the fate of the fallen Servants after being the recipient of a diagonal slash, causing his armor to chip from left to right only, but taking the wind out of him due to the force behind the feint. Just at the precise moment he was about to clash his weapon against Julius Caesar's, an unexpected attack made by Leonidas completely destabilized the black-haired man, giving Circe an opening so that she could constantly bombard him with spells.

"That must have hurt," said a demigod who earned dry looks from his companions for stating the obvious

But grimaces of pain were also on the faces of the audience, as well as the surge of growing anger towards the Servants, what kind of training was that?

The Romans would have even called the projected Greeks barbarians/savages for what they made to their praetor's counterpart, if it were not for the fact that the Romans of that world were also involved.

But they were more surprised by the level of skill that the son of the sea showed, however very few noticed anything peculiar about the Servants, when they were fighting/training with the black-haired demigod

"Are they...?"

Fatigued and sore, Percy retracted his sword before putting it in his right trouser pocket, proceeding to extend his upper limbs width wise as he continued on the ground, ending practice.

"Do you give up now?" This time the question was asked by a little Medusa who had previously chosen not to participate in the training, as she did not like to see how a Master bled unnecessarily due to mere stubbornness.

If the Greco-Romans weren't concerned about the green-eyed demigod on screen, they would have been more attentive to the different attitudes of Medusa's counterparts

"Now yes..." with his eyes closed and breathing heavily, Perseus Jackson managed to answer, extremely tired.

"Wow... I never thought that a Master could train on par with Servants" Gudako herself expressed her thoughts aloud.

But that remark ended in a weary playful laugh from Jackson, who could barely move his head to watch an angry Europe kneel beside him with a bottle of water in his delicate hands.

"He's crazy to train like that"

"Did he hit his head as a baby?"

"Is the boy that crazy yet?"

The audience wondered if perhaps the green-eyed lost a screw, or in the case of the Greeks of the future that finally the Jackson, the sanity he had left was lost.

Several made mental notes about talking to their Percy Jackson, both the young man in the room, as well as the one in the future once he arrives or they return to their times. While Sally Jackson's young son wanted to respond to comments made about his sanity, but wondered the same about his future self and his on-screen counterpart.

"Master fool the one who touched me... look at how you train to such an extent..." whispered annoyed the blonde Rider under her breath, uncovering the small container and throwing the crystalline liquid on the demigod's face, reinvigorating him.

"And if I don't train, who watches your back while you fight?" Poseidon's son immediately refuted, smiling gratefully at the beginning before taking the bottle to throw the rest of the water on his torso after discovering it.

An audible crack took Fujimaru by surprise, who unlike the others, it was her first time seeing how Percy was quickly cured with water, thus further strengthening the fact that he is the son of a god as he told her when he met her.

"Doesn't it hurt?!"

"Is it normal in the children of the sea?"

"That's unfair!"

"Is it normal in the children of Poseidon?"

There were various comments about the abilities of Poseidon's son and several at the sound of the body of the son of the sea healing made a face, as well as the anger they had increased. But only the Atlanteans realized that the amount of water that remained in the bottle was enough to heal their wounds, both cuts and broken bones, it was a limited quantity, of a bottle...

How strong would Poseidon's young son be?...

They couldn't help but turn to look at the young green-eyed teen boy.

"You kicked him with that force for the beating he and the others gave you before, didn't you?" emulating Europe's position, Medea inquired at the giant Berserker, simultaneously ignoring the Rider's frown because of how friendly she was with the Demigod Master.

"GRRRRROAAAR!" looking to the side and crossing his arms, Heracles grunted in a tone that certainly affirmed doubt, then looking at a thin vertical cut that his left bicep had.

"Very mature of you... very mature" Looking at him with little encouragement, Atalanta dispelled her bow, then kneeling with the purpose of nursing the burning that her knees had after having been initially knocked down by the black-haired man.

"He'll see how..."

"Heracles..."

Promises of revenge were being made against Heracles, even if it wasn't the one on screen who would receive it. Though others like Rhode looked at those who whispered those promises of revenge.

Percy took a seat, hissing in pain at the body's persistent discomfort but smiling afterwards as he learned that it was all for a right purpose. A grimace that calmed the vast majority of those present, who thought they had gone too far in the fight.

The audience had very different thoughts about what they witnessed

"You know Gudako, when I laughed before, it was because of what you said..." retracting the shield to the shape of a watch he wore on his left wrist, the young adult made the attempt to stand, having to do it twice due to muscle fatigue and loss of adrenaline, clearly demonstrating that a simple bottle of water was not enough to make him fully regain.

"What is he talking about?"

"What does he mean?"

The audience wondered what Jackson was talking about, he was fighting with equal skill and against several, but only certain individuals mentally reviewed what they had seen for a few moments, noticing certain details of the Servants' way of fighting, making them open completely their eyes. While the Atlanteans realized that although the bottle healed their wounds, it did not cure their exhaustion and tiredness.

"About fighting at the level of the Servants?" Looking at the masculine figure of the demigod who was slowly walking with the help of his summons to a nearby bag, Gudako inquired.

"Yes, that... It was because I'm not fighting at their level. I'm not even sure I can do it at some point" bending down to take the bag after stopping Europe and receiving a gentle slap for it, Perseus Jackson explained with patience

"He can't be serious!"

"He must be joking"

"That's impossible!"

Most Greco-Romans thought Jackson was joking, that he was too humble or gave too much credit to the Servants, only few realized that he was being completely honest, these Servants were on a totally different level than the demigods and very few could think that only certain demigods of ancient Greece could have truly challenged them.

"But..." wanting to oppose what was said, the redhead with golden orbs murmured.

"He's right, Master. We are holding back a lot with him. However, that doesn't leave aside the fact that his rate of learning and growth is quite great" adopting a meditative countenance, a certain hero trainer gave his point of view.

Stupefaction abounded on the faces of the audience members, they couldn't fight at a higher level... or could they? ...

But if... they could really fight at a higher level then... How strong were those counterparts of the Greeks and Romans from this world's past?

"Will he even have a Noble Phantasm or a Reality Marble?" amazed by what was pointed out, Medea Lily sought to find out.

"Noble Phantasm?"

"Reality Marble?"

No one had any idea what the Servants were talking about

"What is a Reality Marble?" confused by the concept, Percy questioned the Servants with what he previously trained.

"Do you remember the 'world' I showed you a few days ago?" answering with another question, Iskandar reminded the demigod of such an event, who stunned only looked at the huge army that brought the redhead from nowhere.

"World?"

The Greco-Romans still did not understand, but from the narrative... could the redhead bring to life the warriors who fought for Alexander the Great's counterpart?

"Yes... You also told me that place was completely different from the rest of the world. And now that I think about it, it's like the barrier that covers Camp Half-Blood" making use of his intelligence, which would make his girlfriend, Sally Jackson's son, proud.

The intellectuals, observers, Hecate and her children, tried to understand what they were talking about, but without much success.

"What would that be like?" Chiron, intrigued by this, asked his question.

"Well, mortals see it as a simple strawberry field, while deities, demigods, or those with clear sight may notice that there are huts and people inside. Even the gods control the weather at will there, and prevent strangers from entering unless they have a permit" carrying out a mental comparison of the worlds, Perseus Alexander Jackson explained himself as best he could, seeing as the experts on the subject nodded.

Percy curious that his other had a middle name, although in previous screenings that detail has been told.

Note: Percy is not a wizard, sorcerer, nor a scholar about the magic of his world, much less about the sorcery and magic of Fate, so he does not understand what a Reality Marble is. And the Servants also don't know how the magic of Percy's world works, for all they know Camp Half-Blood could be like a separate dimension in the forest.

"It would be a simple example... but correct since it covers the basic requirements... But if you want to be able to have a Reality Marble for yourself, you will have to train a lot more to start... And let's not even talk about getting a Noble Phantasm..." the hero trainer said, specifically pointing out the facts that intrigued Gudako about the second Master of Chaldea.

Given the lack of knowledge involved in a Noble Phantasm or a Reality Marble, they could only make theories and assumptions, being Athena, Hecate and the children of these two goddesses, who were frustrated.

But few noticed that Chiron's counterpart didn't seem entirely sure about the comparison, as well as that Percy's counterpart would achieve such things, just as he didn't seem entirely sure that Percy's counterpart would get those things. Although even fewer assumed that it was because of the possible differences between universes or something else.

"And there go my dreams of being able to shoot laser beams from my sword..." murmured the Savior of Olympus, dramatically kicking the empty bottle.

The Friends of Perseus only rolled their eyes, at the response of their friend's counterpart. However, questions also began to arise about the ability that this counterpart of Poseidon's son could achieve by training with the Servants with such brutal training

The bottle rolled to where the door of the room was, generating a dry noise that attracted everyone's attention as they noticed that it was open. And a chilling sensation ran down the backs of all those who trained previously, since for a few seconds nothing happened and the silence continued impassively.

Again everyone was confused as to why the individuals at the screening reacted like this, but only a few could get the idea that due to their condition, the fear was due to the appearance of a certain mortal nurse, because of the things they saw before

"PHEW! I thought that..." Jason began to speak nonchalantly, unaware that everyone looked at him with big eyes.

"Shut up"

"Oh, no"

"Shut your mouth"

All those who had been in bad situations that got worse when they thought it wouldn't happen, muttered or thought about Jason to shut up. Although others who also did it were those who knew or already realized the peculiar luck that Percy Jackson has.

"Don't say that! Don't finish that sentence!" wishing he could be close to the blonde Saber to hit him in the back of the head, Percy could only exclaim.

"... something bad would happen" the Argonaut finished his sentence without problems, earning Medea's deadly gaze.

The Greco-Romans on Olympus could only curse the counterpart of the ancient champion of Hera

And as if that were the prelude to a disaster, the catastrophe occurred when a familiar face briefly appeared looking at them through the crack.

"I see you're hurt..." Nightingale's honeyed voice frightened everyone.

"Heracles, block the door. NOW, NOW, NOW!" ordered the Atalanta, at the same time that she instinctively ran up to the son of Poseidon, joining the group that Circe, Penthesilea, and Medusa Rider.

"GRRRRROAAAR!" cried the named man, even using his sword as an aid to prevent the mortal nurse from entering.

"What the Hades..."

"What...?"

Seeing Heracles fearful would not leave the public's minds for a long time

The rest, for their part, had fallen into utter chaos, where they were all quarrelling over the nectar and ambrosia that Percy had deliberately carried, or waiting anxiously for the demigod himself to use his powers on the water as he had done the first time with the white-haired female.

No one in the audience would ever, ever have imagined the heroes of yesteryear acting as they were seeing them...
