Hi guys! Just want to let you know, but Trials of Apollo is COMPLETELY ignored here. I have read the Hidden Oracle, but I'm gonna ignore it in this story.

-SPOILER ALERT! -

That's because the Seven is scattered, Annabeth is in Boston, Percy is in New York, Frank and Hazel are at Camp Jupiter, Jason and Piper are at school somewhere I don't remember. But I don't own Percy Jackson and his friends or Harry Potter and his friends.

McGonagall's Animagus form is a Tabby Cat, but just Cat is acceptable. Congrats to Risa Silvara, Guest 1, and Guest for getting them right. (::)(::)(::)(::) But, nobody got the three Roman War Gods! Remember, when the Romans converted Athena into Minerva, they took away her "War Goddess" status. The three Roman War Gods that I was looking for are Mars, Bellona, and Mithras. If you remember in MoA, Annabeth has to go through the altar of Mithras, who was originally Persian, but who the Romans adopted as a protector and patron of the Empire. But yeah, nobody got that one.

Risa Silvara: I understand that we've never seen Nico's full potential, but we never really have seen Percy's either. Sure, Percy inadvertently unleashed Typhon, but that was when he was 15! We don't really know Percy's full potential as of him being 17. It never really says in canon. I still think that Percy would beat Nico in a 1v1 duel. It would be fairly difficult, with Nico and Percy landing equally fatal blows, but in the end, Percy would disarm and defeat Nico. Remember, Percy fought for MINUTES against Chrysaor, who had eons of training, while Percy only had 5 years. This is just MY opinion. I perfectly respect that you think Nico is better, and I agree that it's good that Nico is becoming more of a "people person". Thanks for the support, though.

Beckah: Nice, but I'm going for someone else. Sorry!

Chaos239: THANK YOU SIR/MA'AM THIS COMMENT HAS MADE MY DAY! Sorry for the caps, just had to say that. But I probably won't do the part where Percy completely wrecks the wizards faces off. I will probably do a duel between them, for fun, but I won't do a full-fledged smackdown where Percy goes all "Savior of Olympus, Survivor of Tartarus" on the poor wizards. I like writing jealous Harry, too. Glad you like it! Also, thank you for reminding me about Hazel's Mist powers! *mentally facepalms*. I completely forgot! Thanks for enjoying the story!

Annabeth POV:

WHY ZEUS!? WHY!? Why do you have to let our cover get blown.

"A demi-what?" Harry asks.

"Not demi-what, Harry, demigod," Hermione told him, shaking her head.

"What the bloody hell is a demigod?" Ron shouts.

I sigh. "A demigod. A being who is half human, half god. Greek and Roman. What we learned in Ancient Runes," I said.

"So... You are all half god? How is that possible? I don't believe you! Greek and Roman mythology is fake!" Hermione yelled.

In an instance, Percy had Riptide uncapped, and Hermione against the wall. Harry and Ron fumbled for their wands, but I pulled out my dagger.

"Don't even try it," I warned.

Meanwhile, Hermione was flinching under Percy's glare. "It. Is. Not. Fake! We. Are. Demigods!" His voice was steely calm, but it made everyone flinch, myself excluded. Hermione nodded.

"Good," Percy said, more relaxed, and touched the tip of Riptide bringing it back into pen form.

"Question, why are there Greek and Roman demigods at Hogwarts?" Harry raised his hand and stepped forward.

"Because Dumbledore believes that a noseless bald dude, aka Moldyshorts, aka Voldemort, wants to make a comeback soon. So, he called in the cavalry, aka us," Percy explained.

"But what are you supposed to do here?" Ron squeaked.

"According to our mentor, Chiron, we're supposed to protect you three," I told them.

"How? With magic? Demigods don't know magic!" Hermione claimed.

"Naturally, we don't. But all children of Hecate, the goddess of magic, do, and we were blessed by her in order to come here," I responded.

"Still! You come here claiming to have been through more than Harry, now you say your Ancient Greek and Roman demigods sent to protect us from You-Know-Who? What do you have that we don't!?" Ron shouted angrily.

Percy's eyes flared. For a moment, I could see the sea in them, but not the kind, friendly sea, but the merciless one that smashes against cliffs and sends ships to the bottom of ocean. Ron shrunk back.

"What do we have? What do we have? We have much more than you could ever dream of. I can control all things water, talk to horses, raise freaking hurricanes, and I'm a master sword fighter! Jason can control the winds, letting him fly, he can summon storms, et cetera. Hazel controls the Mist, the magical veil that keeps magical elements from mortals, and she controls all precious metals, Frank can shapeshift into ANY animal, Piper can charmspeak, which makes people do exactly what she says, Calypso used to be a goddess, need I say more? Leo controls fire, Thalia controls lightning, Nico can travel through the shadows and raise the dead, and though Annabeth doesn't have any external powers, she's one of the smartest people alive and is a master with all weapons. Reyna is also a master with all weapons, plus she can lend others strength! And that's just our powers. If you want to know what we've been through, we'll need the rest of the demigods, because that would take a freaking year for just us to explain! If you want to know all our titles, then that would take another year, because we have so many! So, to answer your question, we have lots of stuff you don't have, plus, we do all of it wandlessly." Percy finished his rant, to which the Brits where backed against the wall, because Percy scared the living Hades out of them.

"I forgot to mention our weapons. I have Riptide, my awesome pen-sword. Annabeth wields her dagger, Jason has an Imperial Gold gladius, Piper has a jagged Celestial Bronze sword, and a knife, Hazel wields a spatha, Frank uses a bow, Leo has a magical tool belt which gives him countless supplies for building, but when he fights, he uses a hammer, Thalia uses bows, hunting knives, her spear, and her shield Aegis, Nico uses a Stygian Iron sword, Calypso was a goddess, so she has magical powers that she can use without a wand, and Reyna has her dogs, Aurum and Argentum, Gold and Silver, plus her Imperial Gold dagger and her silver pocketknife to fend against wolves/werewolves. Are we done here?" Percy finished ranting again.

The wizards nod, frightened out of their minds. Which makes sense, Percy never gets this ticked off unless it's a monster who annoyed him.

Ron, apparently, still doesn't get Percy. He hurls two spells at us, "Impedimenta! Expelliarmus!"

As fast as lightning, Percy whips out Riptide, slicing downward, destroying the spell. I block the charm by simply raising my dagger.

"Whaaaaaaaa? How did you do that?" Ron asked, awestruck.

"Demigod reflexes. We have dyslexia, because our brains are hardwired for Ancient Greek and Latin, not English. We have ADHD, since demigods, or half-bloods, as we're sometimes called, are meant to be on battlefields, leading troops into combat," I explained.

"Oh," Harry responded for Ron.

"By the way, guys, we're sorry for kidnapping you, and waking you up in the middle of the night. We just thought you we're Death Eaters," Hermione apologized, but Percy waved the comment away.

"It's cool, I would have done the same thing if I was in your position," he paused, then started again, "can you shoot some spells at me? I want to show you what we can do," Percy said with a mischievous grin.

Harry shrugged. "Why not?" All three of them shouted magic. Harry shouted Relashio, Hermione shouted Flipendo, but Ron didn't say anything. Percy spun his blade, sending Hermione's spell flying in a different direction. He sidestepped Harry's spell, and repeating the actions, as both Harry and Hermione sent spells in his direction. They looked awestruck at Percy's mobility and skill. I smirked. Typical Seaweed Brain. Eventually, I joined in on the fight, blowing away the jinxes too.

But Ron came in with from the back, firing two spells at Percy. I watched, horrified, as both hit their mark. One gave him a bad burn, while the nearly blew him up. He went flying, while Ron smirked. I started screaming Ancient Greek swears at him, and begun trying to attack him with my dagger. He flung hex after hex at me, but none hit. I glanced back at Percy. He was staggering around, standing up. But he was on fire, and was bruised badly. Hermione looked horrified, while Harry was blinking rapidly, as if he couldn't fathom what happened.

But Percy, being the Seaweed Brain I know and love, got his sword out and with a defiant yell, plunged it into the ground. A crack spread, and the entire floor shook. I stood fast, but Ron wasn't so lucky. He stumbled and fell into the crevice. He grabbed the ledge at the last second.

"Please! Help me!" He whimpered. Hermione and Harry got up, but they fell again. They crawled over to the ravine and pulled Ron out of it.

They all looked at Percy, who was bruised, scarred, on fire, and bloody.

"YOU TRAITOR! We should just go back to America, then. We'll let you win this war on your own then. When you die to Voldemort, and he comes to America, we'll destroy his army, and kill him, but you will still be dead!" Percy screamed so loudly, the ground shook. Literally, he restarted the quake.

Ron whimpered, "I-I'm s-sorry."

"You better be!" Percy's glare weakened, and it turned back to it's normal state. But he was turning pale from the blood loss and the fire. He then collapsed.

Oh gods, Percy, you're still on fire! I ran over, and tried to pat the fire out.

"Wise Girl, I'm fine! Gods, a little beat up, but it doesn't hurt much, after Tartarus," he whined.

"Wait, you've been to Tartarus? HOW!? That place is literally hell! Nobody has ever survived going down there!" Hermione backed up, terrified, while Ron looked guilty.

"Oh, so that's how you've been through more than me. But I apologize for being jealous, it's just that you seemed so happy, so carefree that I couldn't believe that you could've been though more than me," Harry told us, looking down.

"It's cool bro, I completely understand," Percy said looking him in the eye.

"But, Ron, please try to be smarter next time, don't anger the most powerful demigods of this millennium," I told him. At that, he turned pale.

"Ok, I'm really sorry Percy," he mumbled.

Percy narrowed his eyes, "I'm watching you Ron, but you're ok for now," Ron looked relieved at that.

"Anyways, Hermione, can you summon some water for Percy to heal himself in?" I asked, to which Hermione looked confused, but nodded.

"Aguamenti!" She pronounced, causing water to spew out of her wand.

Percy lifted his hand, and the water obeyed, forming ball. He did a circular motion with his hands, and the water spun around him, dousing the flames, and healing the scars and bruises. The wizards watched in awe.

"Well, that was fun. Also energizing," Percy announced.

"How-How did you do that?" Ron asked.

"Ron, didn't you hear them earlier or do you have short-term memory loss? They-" Hermione started, before Ron interrupted her.

"What's 'short-term memory loss'?"

"When you forget something right after you hear it," I replied.

"But, they're demigods, and Percy already mentioned their powers. He can control water!" Hermione raised her voice.

"Oh yeah, and how did you do the earthquake? Blimey, that was cool, even if it nearly killed me!" Ron said, excited.

"It comes with the 'Son-of-Poseidon' package. I forgot to mention that. I'm a son of Poseidon, Annabeth is a daughter of Athena,-" Percy started, before Hermione interrupted him.

"But how are you two dating? I thought Athena and Poseidon are rivals?"

"Yeah, Athena kind of hated me, until I gave up immortality for her and joined her into Tartarus," Percy waved the question aside, then tried to continue, before Ron interrupted.

"You gave up immortality? You could have been a god?" Ron asked, flabbergasted.

"Yes! Why is that so surprising?" Percy asked. Of course, the Seaweed Brain I know is always clueless. "But anyways, Jason is a son of Jupiter, Piper is a daughter of Aphrodite, Frank is a son of Mars, Hazel's dad is Pluto, Nico's dad is Hades, Thalia is a child of Zeus, Reyna's mom is Bellona, Leo is a child of Hephaestus, and Calypso is the Calypso from the myths, who Leo rescued from Ogygia, her prison/island/home. So yeah," he said, not knowing what else to say.

"Can we go back to bed now? I would like a night of rest without anything that will annoy me, like nightmares and getting kidnapped," I told them. They all nodded.

Together, we walked back upstairs to the Gryffindor tower.

Phew! That was a long one! But it was needed. I hoped you enjoyed it!
