Hey guys, I've been a long time reader on fanfiction, I've just never written anything on it since I didn't really felt the need to. But this was stuck in my head for a while now, and eventually I just gave in and decided to try my luck. I'm not sure if anyone else had the same idea that I did, and if they did please message me so I can move away from what you're doing. I've read all the Percy Jackson books up until the Blood of Olympus, which I will not read since my best friend told me the book pretty much ruins Percy and Annabeth's role in the series, as well as making the fight with the giants and Gaea very anticlimactic and short. So I'll just stick with the story until House of Hades, and then my story changes completely. Only a couple of things for you guys to know: the giant war has ended, and the greek/roman pantheon has been completely wiped out with the exception of Percy. Before the gods faded, Poseidon passed on a bit (and I stress a bit) of his powers to Percy since he will be the final representative of the greek pantheon: Increased power over water and earthquakes (no water vapor travelling or using water without getting tired unless in a body of water), higher physical abilities (lower than captain America by a lot except when in water, then it's pretty much the same). He gets a slightly longer lifespan (life expectancy is about double that of a normal human being) as well as one major power boost that I saw in house of Hades and don't know if he actually uses in blood of Olympus: the ability to control the water in all liquids like what he does to akhlys (blood is included in the power upgrade, but he can't do it for a long period of time). The timeline differs a bit since this story starts at the end of Captain America: Civil War (so spoilers if you haven't seen it) and Percy is 29.

Here's a rough summary of the ages of the cast (not necessarily official to marvel, just how old I imagine them to be):

Tony:45, Cap: 96, Natasha: 88, Percy:29, Wanda:28, Clint:45, Banner:47, Thor: Unknown (and honestly not really important to me), Falcon:38, Vision: 1 (?), Ant man: 39, Spiderman: 16, Black Panther:34, Bucky:96.

SAM POV

Sam was honestly getting really tired of staying in the underwater prison. He was starting to feel cramped in his small prison cell and watching Wanda trying to get more comfortable in her straightjacket was painful to watch. The whole team that supported Steve was starting to get restless, not in the least because everyone in the facility seemed to be constantly on edge, and he would bet it was because of the cell that was right next to his and that had the lights turned off. Someone or something was definitely in there since the guards kept checking the locks, and every question about what was inside was met with anxious stares between the guards and silence, so you could forgive Sam for starting to get nervous and expecting a three headed monster to just get out of the cell and kill everyone. So to say Sam was happy to see Steve was a big understatement. As soon as Steve opened the door to his cell, he literally jumped out of the cell and was ready to just get out as fast as possible, which was apparently not in the cards since apparently, curiosity had gotten the better of Barton who just needed to see what was inside the cell, despite everyone else not agreeing with him. A small argument formed between the team members, and that's when Steve decided to intervene:

"Guys, come on! I didn't get you out of here so you could argue the second you were free! And Clint, think for a second, if what you said was true, and the guards were nervous even with the door kept constantly locked, do we really want to see what's inside that prison cell?"

"Let me think for a second… Yeah I really do". Clint was really getting on Sam's nerves, and apparently he was wearing down Steve's patience since the embodiment of Patience sighed and pinched his nose:

"You do realize that whoever or whatever is in there is probably a criminal and extremely dangerous right?" While Steve had a point, Clint quickly countered with the argument that Sam already had in his head: "Oh like we were criminals? Gee cap, we really were the most dangerous criminals on the planet, so I completely understand why they locked us up in here. Besides, it's not like we can't take care of ourselves, we have a pretty powerful group here so I'm sure we could handle whatever came out of that room." The group started nodding their heads in agreement with Clint, since apparently curiosity had gotten the better of them, and Steve finally relented and opened the door to the blacked out cell.

If you had asked Sam what he would've thought was in that room, the absolute last thing he would've guessed was a normal looking person kept unconscious by fluids being poured into his system thanks to an IV bad that contained anesthesia to keep him out of the loop. That person was a man who looked like he was in his late twenties or early thirties with messy dark black hair that looked like it hadn't been cut for a couple of months since it was about shoulder length, and lying down, he thought his height was around 6'1 or 6'2. The man looked well-built and relatively normal, so the only thing that Sam could think of that put that guy in this prison was one of two things: that person was either a serial killer that did a lot of damage, or the more likely option was that that person has powers that were scary enough to keep him unconscious so as to not risk having them unleashed on the world. Wanda broke everyone out of their stares:

"Well? Are we going to wake him up or not?" she said, looking at Steve.

"Not right now, that man probably has powers and I don't feel like dealing with him if he's hostile while escaping this prison. Anyone have any objections?" Everyone shook their heads.

"Good, we'll just carry him until we get out of here and reach the safe house. Then we can wake him up and see what the fuss about him was. Any idea why he was here?" That last question was directed to Sam.

"None, but I do have one question: where's the safe house?" Steve gave a small smile at that:

"Wakanda, T'Challa has generously accepted to hide us there and protect us until the government clears our name, so please don't create any problems while we're there, I feel bad already that we're implicating him and risk bringing him down with us." At that last point, most of the team looked at Clint, who just shrugged his shoulders:

"No promises there, I'm still going to explore the area surrounding us and may or may not play any pranks."

Everyone just rolled their eyes at that and Steve just sighed and went to unplug the man from the machines. Being careful as to not wake him up, he picked him up gently and started moving out:

"Come on guys, let's get out of here, this guy is not going to stay unconscious for long and I'd rather be a long way from here before he wakes up."

With that, Steve started to move out, with everyone else following him and ready for the trip to Wakanda. Unbeknownst to them, the man they had just picked up was going to affect their lives in a very big way.

Well, here's the first chapter everyone, hope it interested you. I'm not sure when the next chapter will be posted, as I am in college and have a pretty busy schedule, so I'll write whenever I can and post the chapter as soon as it is ready. Also, I'm not a big fan of author notes, so don't expect me to write another one that big at the beginning of the chapter. Let me know what you thought of the idea/story, good or bad. Any criticism of my writing is also welcome as I'm always looking to improve.
