AN: Hello my readers this is Trmiku, and this is my first time writing fanfiction on this site... or anywhere. This is going to be a set up chapter and will not contain the smutty goodness yet. Next chapter will though. Also, HoO events that occurred after PJO doesn't happen in this story. So in other words, please be gentile. I know I will not please everyone, so any criticism is welcome, but I ask that you do not do it in an offensive way. (Ex. I think your work is pretty good but needs improvement such as...) Or you could ignore that and flame away. (Ex. Your work is totally shit and you should go kill yourself...) Please don't do that.

Anyway enough of my rambling, and time for the disclaimer:

I by no means own Percy Jackson or Marvel they belong to their respectful owners.

This is going to be a Percy POV only story unless stated otherwise.

As I was running through New York fighting of the Draken, I stepped in a small, strange puddle of blue, black and orange sludge that was stuck to my foot for the rest of the battle, but I didn't pay it any attention because it did not get in the way for the duration of the battle. As I was fighting the many battles after I stepped in the sludge, I started to feel slightly more energized, even with Achilles blessing working its magic. As soon as Luke sacrificed himself in such a noble way, and the events that followed occurred, I started to feel strange and I needed to get back to camp and rest inside of my cabin.

As soon as we all returned after the battle and Olympus, everyone started celebrating, and I passed several people who were trying to stop me and congratulate me, but I kept walking. When I finally went inside I instantly passed out and fell onto my bed.

For once in my life as a demigod my dream was not some subliminal message about tragic events that were supposed to happen to me or my friends. I was flying through New Yo- wait, scratch that. I was swinging through New York on what looked like webs that were half orange and blue with a thin black line sticking out wrapping around the main line. Look at the webbing of symbiotes and imagine something like that. I felt so alive and powerful as I flung myself through the city. When I landed on a window I looked in the reflection but I didn't look like me.

I was in a strange suit that looked like Spider-Man's, but instead of red orange replaced it. The suit looked like the suit was moving and where the two colors met in different areas it swirled and little splotches of miss-matched colors in the different areas. The black details in the suit looked like they were moving and, occasionally in different places, they would become wavy with a symbol that looked like a wave in a circle on the center my chest.

I started to hear a female voice in my head. I then realized it wasn't in my head but was the suit talking to me. She said, "Hello Percy, you are probably wondering a lot of different things right now."

I said, "Not really, I mean I am dreaming."

"That would be where you are wrong," she said. "You are not dreaming. You are really in New York right now."

"Now you see, that is not possible. I passed out the second I stepped foot in my cabin."

"You are right there but when you passed out I took the liberty of taking over and bringing you here."

"Why would you take me here?"

"New York is my birth place."

"Yeah that's where I lost you. Suits cannot be birthed, and the fact that I am not frickin' Spider-man!"

"Hey calm down, I understand your confusion. If you remember while you were battling that Drakon and you stepped in something, that something was me."

"Wait, wait, wait, wait. I stepped in a living organism that can change into a suit that has the power of Spider-man?"

"Yep that just about sums it up."

"Mkay, just wanted to make sure we are on the same page."

Just as I said that, about five blocks down from the building I was perched on, or I guess we if you count the living suit, an explosion burst out into the street. I saw that it was a bank where the explosion came from, and so naturally I sprung into action. I immediately regretted that decision due to the fact I had no idea what I was doing or how to operate the suit.

I started hurtling towards the pavement when the suit noticed I had no idea what I was doing and shot a web that latched onto a building and I was swinging through the air again. 'Just follow your instincts,' a voice in my head said. 'Wait a sec, you can talk in my head, too?' I thought. I took the suit's advice and I flipped gracefully in the air as I detached from the web and shot another myself 'Yes we are linked both physically and mentally.' the suit informed me. 'Great just what I needed, to be linked to Suit Lady.' I thought as I neared the bank. 'You don't need to call me that,' she said, rather irritatedly I might add. 'Well then what should I call you?' I mentally asked as I landed in an assassin's creed pose on one of the cars that was in the street outside of the bank. It was stopped due to the explosion. 'Hmm… you could call me Vapor due to your water affiliation.' Vapor said after some thought.

I looked inside the bank to see that a large man in a rhino suit broke open the vault with everything scattered around inside like he cleared a path straight from the street. 'Wait you know about my powers?' I thought a little shocked. 'I know everything about you' Vapor said a little snarkily. My heart dropped, 'W-w-wait… e-everything?' I asked very scared of her answer. 'Yes, that includes your - ahem - nightly activities.' Vapor sounded like she was, if she had a face, smirking.

Just as that revelation hit me the rhino guy looked at me and said, "Hey Spider how the fuck did you get here so fast? Oh, it doesn't matter. I'll still crush you like the little shit you are."

"Wait, who?" I asked bewildered. Then the I remembered my resemblance of Spider-Man "Oh, right. Hey man I'm not Spider-Man."

"Then who the hell are you?"

"I'm - uhhh - Vapor, yeah Vapor." When I said that I heard 'Hey, did you just steal my name?!' Vapor asked in outrage.

"Huh, never heard of ya"

"Well I am still going to stop you, uh, rhino guy."

"Arghhh!" I heard him bellow as he began to charge at me. For a second I didn't know what to do when I remembered what Vapor told me and I followed my instincts. I jumped, did a half flip, used one arm to push off of his head with my fingertips yelling "Torro, torro!" and landed gracefully on the bank sign in the same pose I began in. 'Very good.' I heard Vapor praise me in my head.

Just then I saw a red and blue blur go by and Spider-Man landed about twenty yards away with his usual quips. The rhino guy said, "There you are you little shit. Why are there two of you now?"

"Well I don't know, Rhino," Spider-Man said to I guess Rhino (makes sense). "Hey new guy, who are you?"

"Well I'm Vapor." I informed him.

"Well kid, I like your style, although you look just like me, I'm flattered," Spider-Man said. "You should probably head home kid, I can handle it from here."

"I can handle myself," I informed him. 'Actually I agree with him, I haven't reached my full potential yet. After all, I was born yesterday." Vapor told me.

"Actually I will take your advice. Anyway have fun with horn face over there." I joked.

"That's right coward, r-," Rhino began but was immediately silenced by some of my webbing.

"Hey thanks for shutting him up for me. Hope I see you around kid." Spider-Man shouted as I swung away, and he sprung into action against the Rhino.

I went to the water to swim home to Camp-Halfblood because it would be faster than walking with my powers. When I touched the water though My body dissolved into it and I moved extremely fast toward camp. 'Woah, I didn't know you could do that!' I thought. 'Neither did I.' Vapor informed me. 'Remember I was born yesterday. I do not fully know the extent of my powers either.'

I quickly arrived back at camp and went straight to my cabin. I began to reflect today's events and all that happened. I think I am going to like having and being vapor.

AN: Well that was the first of many chapters of Percy Jackson and His Symbiotic Relationship. Don't worry we will get to corrupting our young hero here very soon. Please let me know what you think and feel free to give me any advice. This will contain sex with many different characters and suggestions are welcome as to who you would like to see with Percy.
