Tony POV

"Vision, can you go make sure that FRIDAY is operational?" I yell over the sound of my music.

"Of course, sir."

Vision comes back a couple minutes later with interesting news.

"Sir, FRIDAY has scanned the city as one of her routines, and she has detected some life forms that are extremely powerful. Almost as powerful as Thor."

"Huh," I say as I turn off my music. "FRIDAY!"

"Yes Tony?" FRIDAY answers.

"Call the Avengers for an emergency meeting."

"Very well." FRIDAY replies. I head upstair with Vision, and I see the Avengers already sitting at the conference table. Fury, Coulson, and Hill are here too.

"So, Stark. What is it this time?" Clint asks lazily.

"Well, FRIDAY has scanned the city, and 11 VERY powerful people showed up. I think they could be threats. Fury?" I start off the meeting, then look to Fury for how we advance.

"Well. We may have to question them. Lets just see how they do. Clint, Nat, Stark, Wilson, and Rogers. Follow them around the city. Station at exits of the city, and follow if near." Fury instructs.

"Yes sir." We all say, then get up to go outside. I, however, will be watching from my lab.

PERCY POV

"Annabeth!" I groan.

"What Seaweed Brain?" I hear her melodious voice answer.

"What are we going to do?"

"Ideas?" Annabeth answers as she looks around at the 11. Everyone shrugs.

"We could go sky-" Leo starts, then is punched by Nico.

"We are not doing anything that involves going through the sky at high speeds!" Nico snaps.

"Hey Neeks, calm down." Will whispers, rubbing Nico's back.

I look around us to scan for monsters, and I see a dude in a black coat and a WW2 Veterans cap. Odd, cuz everyone from that war is either dead or almost dead. I look the other way, and I see a woman with a clipboard, bright red hair (Like, ARES RED), and sunglasses. She is heading this way.

"Hey guys! 12:00, woman with a clipboard. 6:00, man in a WW2 veteran cap that looks legit!" I tell the others.

The woman arrives at our table.

"Hello! I am with the Strategic Homeland Intervention Enforcement and Logistics Division. We are taking a survey for all of the teenagers in the city about what they think of the security here." She says.

"Wow. I guess they just wanted it to say SHIELD." I say sarcastically.

"I guess." She replies. I hold a finger up, and turn to the others.

"Should we trust her?" I question.

"Well, nothing bad has happened so far." Annabeth points out

"Yeah, let's just be cautious." Piper adds.

"Okay." I say, turning back to the woman.

I see her finger up to her ear, then I hear screams and then pain racked through my body. I convulse to the ground, but still awake. The fountain explodes, but I am hit on the head. I see darkness, then I see the 11. We are connected by Nico.

"WHAT JUST HAPPEND?!" I scream.

"We don't know!" Jason says, apparently the first to be knocked out.

NATASHA'S POV

The teens collapsed, and then Steve helped me put them in the van. The shadows seemed to darken around us when the goth kid got knocked out. The boy with blonde hair and freckles freaked out over him, then collapsed. The boys with blonde and black hair were the heaviest. We lugged them into the van, then drove them to Stark Tower. When we got there, we put them in the interrogation room. After a couple minutes, which was extremely fast, the boy with jet-black hair and green eyes woke up first.

"ANNIE?!" He screamed as he shook the blonde girl. She was next to wake.

"Percy! Where are we?!" She asked. The blonde muscular kid woke up next, and then he woke up the brown-haired burgle with a choppy haircut and feathers. She then screamed at everyone to wake up, and then did. I decided to walk in, along with Clint and Stark, to question them.

"So. Who are you?" I question, getting right to the point.

"YOU!" Percy shrieks, not seeing the piece of plexiglass in-between us. He smacks into the glass, while I just wait for them to calm down.

"Sorry, but we found that you were extremely powerful, and we weren't sure if you were a threat." Stark says, trying to reassure them.

"Oh yeah, we have heard that more than enough times." The blond girl, Annie, snapped.

"Annie..." I start, then she screams, "DO NOT CALL ME THAT. My name is Annabeth."

"Okay, Annabeth," I try again, slowly. "Who are the rest of you?"

Percy looks murderuous, until the girl with the feather in her hair tells him to answer.

"I am Percy Jackson," He starts. "This is Annabeth Chase," he points to the blond girl. "This is Jason Grace." He points to the blonde muscular boy. "This is Piper McClean." He points to the girl with the choppy hair. "This is Frank Zhang." He points to the burly Asian boy. "This is Hazel Levesque." He points to the African American girl with gold eyes. "This is Leo Valdez." He points to the Latino boy. "This is Calypso Kipouros." He points to the girl with almond shaped, brown eyes. "This is Nico di Angelo." He points to the goth kid. "This is Will Solace." He points to the other blonde kid who is sitting with Nico. "And this is Reyna Avila Ramirez Arellano." He points to the girl who looks very fierce. "There. You happy?" He spats. "Now who are you, and where are we?"

"Thank you. We are the avengers. I am Natasha Romanoff," I say. "This is Clint Barton," I say as I point to Clint. "and this is Tony Stark." I point to Tony. "There are more of us, but we are the calmer of the rest of them. You are in Stark Tower."

"WHAT?! I LOVE THIS PLACE!" Leo yells.

Percy then gives him a glare, and Leo shuts up.

"So, why did our radar show that you are so powerful?" I question further.

"We can show you. can you take us to a place where we won't blow this place to rubble?" Percy answers, giving a look to Jason.

"I guess, um. How's the roof?" I reply, not knowing what to do, since they could try to escape.

"Great! We are going to need a gallon of water, a piece of jewelry with a gem on it, a part of the balcony with shadows and light, two packs of pipe cleaners along with a rubber band, a plant, and room to move around." Percy replies.

I take them up to the roof, so that they can't run away or jump off without dying.

"Okay. Here are your materials." I say as Clint and Tony bring up the materials.

"Percy, go first." I intsruct.

FIRST CHAPTER DONE!
