"Na na na na na na na na na na na na! Na na na na na na na na na na na na! Na na na na na na na na na na! "
~ Na Na Na (Na Na Na Na) by My Chemical Romance from the album 'Danger Days: The True Lives of the Fabulous Killjoys)

(Song is on the side. It can be found on Spotify (with the rest of the album) and on YouTube)

I didn't count the na's by the way. Could be less or more than in the actual song.
Marvel owns the Avengers.
Rick Riordan owns the rights to the Percy Jackson series. This includes all the books and movies and all related works that involve the PJ-universe.
And I, Maria, owns this story!

By the way, this story happens after Captain America Winter Soldier, but without S.H.I.E.L.D. totally wiped away and Fury is the director, and before Avengers: Age Of Ultron! (Note 09- 10 - 2019: We're working with our own version of the MCU basically!)

3rd Person's POV

Steve Rogers is not an ordinary man. He's out of time, has a big heart and cares for the world and its safety. Nightmares would sometimes plague him, the crashing of the plane in the water, the 'dying' of Bucky, the fight with Bucky...

The loss of a living friend is worse than death. Knowing the friend is alive, but not being able to be in the heart of the friend. No recognition in the face as he looks at you. No memory of you in his mind. No love in his heart as he hits you in the face. All of this while your mind and heart are overflown with many thoughts and feelings. These thoughts would sometimes attack him in the middle of the night while trying to sleep.

Steve had searched for months for his lost friend. Hoping he would be able to help him regain his memory and help him through the process of 'new time'. Help him understand the modern way of things.

Now Steve took one month to set his mind straight after the whole situation with Bucky and what happens? He's working for S.H.I.E.L.D. by kidnapping a teenager with PTSD from a graveyard. Never had he found himself thinking that he was a heartless man by doing something for S.H.I.E.L.D.. But now, he did.

Bruce Banner looked at the screen in front of him, showing Perseus Jackson in the cage of glass and steel while screaming his lungs out and tears streaming down his face.

The man's heart hurt by looking at the traumatized kid. But as soon as he heard the lab's door open, he clicked the screen away. There he was Steve Rogers. "Banner, we need to talk."
Bruce leaned down on his desk. "We need to find more about that kid. There is more to him than Fury thinks. There is just... Something is wrong with the entire situation. It doesn't make sense." Banner nodded at the words. He picked up a notebook, the only thing Fury could not immediately check with S.H.I.E.L.D. As he started writing he said, "We need to find out more about the kid's family, his education and those years he just completely went off the radar. In those years, I think, lays the key."

Time to find out about Perseus Jackson's life.

Percy Jackson's POV

When I woke up from another nightmare, I found myself laying on the ground in some kind of glass cage. I groaned, remembering what had happened earlier. My throat was burning, probably because of screaming. I sat up, looking around, trying to investigate the environment. But all I saw was the ground and glass of the cage and the steel of Stark Tower on the outside. I felt numb as I stood up. There was a tension in the room that could not be explained until Fury came in. His one eye glaring at me, trying to scare me. "So Perseus..." "Percy." "Percy." He said back angry. "Are you a terrorist?" He asked me, standing still and his arms crossed. "No." He smiled half. "You better tell us now before you get hurt." "Why would I get hurt?" Fury walked over to a panel and pushed two buttons. Suddenly I saw a robot come into the cage through the now open roof. Two red eye lights, a round head, six steel arms, and the big triangle body was standing on two titanium legs. What the Hades is this place? "Are you a terrorist?" "NO! Man! You sound like a little kid trying to convince his dad to buy a dam toy!" Fury glared at that and pushed again two buttons. The roof closed and the robot activated and came at me. I looked around, making a plan in my head. As soon as the robot tried to grab me, I jumped up, using his arm as a footstep to get further. As I landed on the ground, I turned back to the robot. Grabbing Riptide out of my pocket and uncapping it. I knew what Fury was doing, but it was either me or the robot. And I'm not giving up that easily.

After about five minutes, the robot was broken in pieces on the ground. I put back Riptide and felt lightheaded. I sat down against the glass, not caring about Fury staring at me in shock and anger. "What are you?" "A happy human. Haha..," I said sarcastically. Fury grumbled. "You know Fury, let's talk more about you. What makes you kidnap teenagers from a graveyard, put them through some tests and eventually put them in colosseum 2.0?" "To protect the earth, mister Jackson," Fury said as he was gritting his teeth and turned away, walking away.

You can say all you want, but I make more sense than him. Seriously, first off, because he's the leader (obviously), has me kidnapped while grieving on a cemetery, gets me tested for stuff I don't understand and then tries to kill me with a bloody robot. Well, that last one didn't work out the way he wanted. I think...

Bruce Banner's POV

As Steve and I walked into the room filled with files, we heard footsteps. We then saw Natasha and Clint. "What are you doing here?" Steve asked. "We want to find out more about that Jackson kid, what are you doing here?" Clint answered and asked. "The same." We walked on as a group of four instead of a duo this time. And as we got to the door, we saw Thor and Tony approach. "What are you guys doing here?" Natasha asked them. "Curtain and I want to find more about that kid that cap brought in," Tony said. "The better question is, what are you doing in front of the file room?" Steve lifted his shoulders for a second. "Uhm, the same. Now, instead of talking the whole time, let's open the door." We nodded in agreement and Clint pushed the button, revealing a trashed file room. We walked in step by step. "What happened here..." Natasha asked to no one particular while looking around the unit. "Come on, we should not be discouraged, we are the damn Avengers if we can beat some aliens, we can do this," Steve said.

So there we went. We started searching, putting the files that were not needed on piles on the empty tables. So many files, so many people, lives, souls, all kept in one room. It was weird and fascinating, that with one glance into one of these files we could find out a lot about the person with his or her name printed on the front.

Eventually after many hours, I saw Perseus Jackson printed on top. I yelled happily, "Guys! Found it!"
They sighed in relief and I picked up the file, revealing a photo from a security camera in... Greece? His figure was blurry, but you could recognize his face if you looked really good. "What does it say?" Clint asked.
I started reading. "Terrorist actions, kidnappings, disappearings. It started getting rocky when he was twelve. He was involved with a volcano eruption. He blew up a lot of schools, not being able to stay in one for longer than two years." I said out loud while reading on. "What does it say before he was twelve?" Natasha asked. "Well..."
I read it and my body and face got more serious. I read out loud, "When Perseus was around five, he started getting new scars and bruises every day, suspecting an abusive parent. Although teachers, other parents, and the police were familiar with this case, no action was taken, because of his stepfather, Gabe Ugliano, always interrupting investigations and reassuring the police more than once nothing was going on in his household. It is believed his stepfather is the person who has abused him from age five to twelve. Mister Ugliano mysteriously disappeared then and has not been seen 'til this day."

Silence fell in the room as we all thought about the kid's past. "What about his mother..." Stark said, or asked, softly. I looked at the file once. "We should inform her!" Steve said while standing up. "That is not needed..." I said, almost in a whisper. "Sally Jackson passed away about three weeks ago." Steve looked at me in shock. "There have to be other relatives, right?" "According to this, his father is unknown because he is lost at sea, probably drowned. No grandparents, no aunts, no..." "Guys..." We all looked at Tony. Shocking us all, he was crying. Thor walked over to him and patted his back, a little too hard from my perspective, but Tony didn't seem to care. "What is wrong, Man of Iron?" "Sally Jackson... She was my sister..." We were all silent. "Tony, I'm so sorry for your loss..." Natasha said.

"She just disappeared one time... I... I didn't understand... I thought she was living her dreams... She was such a lovely person... She could bake like a goddess... Oh god..." His sobbing started to get worse. "I just wish I knew... My sister... With that monster Ugliano... I... I... I need a fucking drink..." He stood up and started walking toward the main room with the view over New York City.

3rd Person's POV

It took Tony Stark a while to return to his normal self. His sadness getting blessed by the alcohol in his system. But for once, he didn't drink until he was numb and sick. He drank one drink. One. Remembering his younger sister in memories that were lost a long time ago. His eyes shifted to a little cupboard, next to the alcohol. He stood up and walked towards it. Opening the cabinet he felt many emotions running through his mind. He picked up one of the only old things in Stark Tower. A wooden box. He picked it up and closed the cabinet, walking over to the couch and putting the box on the table. The man who was normally so harsh and sarcastic was crying. He opened the box, revealing some little stones, a bracelet, a necklace and a lot of pictures.
