AN: Percy will be extremely OP in this because he's genetically superior to even the best hunters and hunteresses. So naturally the only thing to do is make him more OP, Percy went to Tartarus alone and Tartarus erased his mortal blood and replaced it with corrupted angel blood, also I'm shit at explaining stuff so just go with it.
Also why do people think Percy's extremely strong because of him holding up the sky, that's stupid, Annabeth, Luke and Artemis all did it for a longer time than him even though Annabeth is probably weaker than him, the only evidence he is physically powerful is that he can parry blows from titans and giants, beings born to fight gods and the stuff gods are made from. Oh yeah, I made this a Percy/Ruby because why not and I haven't seen any of these so I shall make one.
Percy/3rd person POV
When Percy woke up, his head hurt like shit and the moon looks like it had part of it missing so he decided to look down and try to remember what he could.
Me time skip
It was all going so well, the crew of the Argo II had gotten to Greece and, despite the long and perilous journey they were ready to fight and beat the shit out of giants, also the gods had decided to pull their heads out of their asses and join their children in fighting the annoying stuff that their children shouldn't even have to fight.
Naturally it all went to Hades.
The moment they saw the giant monster army they knew it would be stupid to try and fight the giants whilst not having blood spilled and, instead of asking one of the gods to go into their divine form and obliterate them all, sent Leo, Frank and Hazel in their stead. Even after sending out three of the most destructive members of the seven (Percy can cause earthquakes powerful enough to erupt a volcano and make hurricanes powerful enough to fight titans on even ground after having been destroyed before.) The monster army seemed to only get bigger.
It would take most of the seven to hold off or destroy all of the monster army, but someone was needed to fight the giants, who did they send you may or may not be asking yourself.
Percy
Yup they sent Persassius Jacksasson to fight an army of giants.
And this is where we enter.
I'm terrible at fight scenes so this could be really bad.
Percy subdued Polybotes in his fathers element whilst waiting for someone to kill it.
He wasn't Hera waiting for Zeus to come to his palace on Olympus.
In other words he was not disappointed.
Percy watched as a stray silver arrow pierced the head of the idiotic giant who thought he could kill Persassiuss Jacksasson.
Percy rushed over to Artemis, where she was having some semblance of trouble against Gration.
He slashed the Achilles Tendons of the giant before stabbing it in the head with Riptide. Artemis released an arrow before the giant crumpled to dust. She nodded her thanks before we turned our separate ways, Percy to help Hephaestus, who was starting to lose against Mimas, and her to do whatever the hell she does.
Percy, as I was saying before, rushed off to fight Mimas, he summoned water and splashed it all over the giants head, promptly shocking him enough for Percy to make a spear of water and pierce the chest of the Giant, consequently giving the big H time to smash his brains head in.
By this time, Percy was completely focused on the battle and started to gain blessings. Mars decided to bless the Greek Praetor giving him a major boost in all his physical attributes as well as a complete set of knowledge on all forms of martial arts and weapon styles. Athena, deciding it safe quickly sent her blessing to the boy allowing him to form battle strategies and tactics a lot easier, it also made Percys ability with knives and spears much better. Hermes' blessing made Percy able to lie much better, it also gave Percy the ability to move faster and nearly silently. Percy can also read, write and speak any language now.
Apollo also blessed Percy allowing him to assess wounds and the best ways to heal them with but a glance. His blessing increased Percys accuracy with non-archery long-range weapons, like a sniper or any other gun, or throwing knives. Demeters blessing made Percy amazing with a scythe and scythe-like weapons. Aphrodite blessed Percy allowing him to have a weak version of charmspeak, made him irresistible to anyone who was into boys, made him able to change his appearance at will and sense all forms of love, not that any of that was important in battle.
Percy rushed over to where Apollo was fighting Leon and went for the same tactic as he did with Artemis' bane.
Percy looked around, observing the battle ground for the biggest threat, he saw Athena was holding off Enceladus pretty well, Periboia was basically just having a beauty contest with Aphrodite and Hermes' bane was neck and neck with him, and Porphyrion was holding off Dad and Uncle Zeus pretty well.
Percy sped off towards them, forming a plan in his mind. When Percy was in Tartarus he learnt that he could control Ichor so he controlled Porphyrions, stopping him and giving Percy the time he needed to form a spear of water and pierce the head of the giant king. Percy slowed down, for the first time noticing the electric blue and sea green glow around him diminish.
"What... was... that?" Percy panted out to his father and uncle.
"You haven't noticed? Some of us deities blessed you as you began fighting, from what I saw, Hermes, Apollo, Athena, Mars, Aphrodite, Demeter, your father and I have blessed you." He expained what the blessings did." From your father it should just give you a major power upgrade in your birth powers as well as another form of travel, another gift we discussed was that we have imbued the power of the golden within you, you now have the ability to heal anything by merely rubbing your hands together and placing them on the wound. From me you have better control over the winds and lightni-"
Zeus was cut off by an outraged roar of disgust.
"CURSE YOU! MY CHILDREN!" The voice was clearly Gaias, looking around he saw Jason and Piper both had blood dripping from their arms.
"FUCK! EVERYBODY GET READY! JASON! PIPER! BANDAGE YOUR ARMS YOUR BLEEDING!" I screamed at the top of my lungs as crazy laughter sounded all around us "Fuck, Dad, Uncle I need you to evacuate everybody. I'll hold her off as long as possible- Dad no. Just go. Ive already killed a Primordial and held another at deaths door. I'm the most suitable for this. Storm or fire, I can be the storm, ask Hephaestus if he can give me partial control of fire so I have double the chances, you need to get away and gather your strength."
Without waiting for a reply, Percy sped of to what looked like the physical form of Gaea, taking a glance back he could see his father and uncle helping the other seven away from the destruction about to happen , aswell as Hephaestus throwing a red glowing orb at him, assuming it was fire he started up the biggest storm he could and redirected the power he felt in the orb into the storm. Making a literal fire storm. Percy leapt at Gaia, clashing his sword against hers in a mass struggle.
The fighting went on for a while, before Percy had an idea, he had minor control of the winds even before he had Zeus' blessing, Percy flew up for a few seconds and made two spears of water, one piercing Mother Earths head and the other her stomach, after this he used his control over the winds to force her away from her domain.
"CURSE YOU JACKSON! I CURSE YOU!
SHOULD I FALL TODAY YOU SHALL AS WELL! NEVER WILL YOU SEE YOUR FAMILY AGAIN! A NEW DIMENSION! A NEW TIME!" Her wailing was cut off by an explosion, her exploding actually, the fire that he kept pumping inside of her wounds had finally built up and detonated, completely destroying her and scattering her like how he did to Kronos. Percy had passed out in the fall, but knew well enough that a curse from a deity as powerful as her would come true.
Unknown to the demigods, the gods opened up an iris message to camp half-blood, thus stopping the war between the Greeks and Romans, causing a peace treaty. Said gods assumed they would have 5 minutes to quickly give anything they thought Percy would need, and that they did.
Apollo and Artemis quickly blessed a sniper so it would always hit its mark, and fused it into Riptide, allowing it to be accessed by a button on the side.
Demeter did the same for a scythe. Hera gave him 15 golden apples, for any friends he may make and their partners. Poseidon gave his favourite son a replica of his trident and fused it into Riptide like Demeter and the archer twins.
Finally Hestia gave Percy the ability to control hope, and different types of fire (Normal fire, Greek fire and a fire specific to him.)
Not a moment too soon were these gifts received than a portal opened up beneath Percy and took him away.
"Sally... how will we tell Sally?" Poseidon whispered incredulously...
When I came back to reality, a voice echoed through my mind, "Child," It said, effectively causing me to fall on my butt. "I must educate you about this world, it is both very different and very similar to your own."
"Who are you" I asked out loud, "And what are you doing in my head?" I felt what I assumed was amusement from the being in my head.
"I'm in your head because I need to be," She, I was pretty sure it was a she, said with a slight chuckle "As for who I am you may call me Miss. C." I thought about this for a second.
"Ok Miss. C, what do you mean by the 'this world is both very similar and very different to the world you knew." I asked concerned.
"Well," She said, "There are many different factors to this, including..." She then explained, in-depth, the concept of aura and dust, and the history of the world known as Remnant, she also went on to describe the significant figures of the four kingdoms. She then discussed the topic of weapons, "I will make some modifications to your weapons and armour to help you fit in if you don't mind." She said.
"What's wrong with my weapons?" I asked, my hand twirling Riptide in my pocket.
She chuckled, "They scream magic, and magic isn't really well known around here."
I huffed, "Alright, make the changes you want." There was a pause, and then it started to glow so brightly I could see the light even when I closed my eyes. When I saw that the glowing had stopped, I opened my eyes. My armour now had a general theme of black with gold lining, the armour seemed to be one piece, allowing more movement, while at the same time leaving no weak points, on my left arm was a watch face that looked suspiciously like the shield Tyson had made for me, on the right arm was what looked like a scream, I would play around with that later. My helmet had an electronic heads-up display that identified things that ranged from the temperature to the types of trees around me. On my left hip was a sword and scabbard, the sword, I realized, was Riptide with a thicker pommell, what looked like a trigger under the guard and 3 buttons on the sides of the hilt, I killed it out of the scabbard and, to my surprise, it was just as balanced as ever, but the blade was no longer bronze, it was black and silver.
"What do the trigger and buttons do?" I asked, no longer stupid enough to test it.
"The trigger" she said" infuses the blade with dust, which is loaded into the bottom of the pommel, I also made the blade an Adamantine silver and Ebony alloy, so be careful not to kill humans, the button on the bottom part of the left side of the hilt turns it into a trident, the button on the top part of the left side turns it into a scythe, the button on the right side of the hilt turns it into a sniper which will never miss, now shut up and let's begin the training."
