     One day Peter and Tony go to test fly a spaceship that Tony had made. As they walk in Tony makes eye contact with Peter "Alright don't touch anything unless I tell you to do so. Cool? Cool." Tony made sure that he kept an eye on Peter because he knew Peter was going to touch something anyways.
As Tony begins to launch the rocket Peter keeps himself by the back wall to resist the urge to press a button. He also makes sure won't fall over when they get off the ground.
After they lift off into space and run some tests Peter looks around wondering how Tony knows what all these buttons and levers are for. Peter sits down next to Tony wondering why he didn't do that before. Peter then clicked a button next to what looked like the Find My iPhone icon.
"I told you not to touch anything Peter" says Tony without looking from the windshield
"Well technically you didn't hear me agree to not to touch anything sooo..."
Tony pauses "Don't be a smartass that's my job, okay"
Peter stays silent
"I didn't hear you agree" says Tony while holding his hand to his ear.
"Okay"
"At least you only turned on the tracker."
Peter looks at the tracker and sees a dot that indicates that something is there
"Mr. Stark there is a little green thing on the Find My iPhone thing"
Tony looks over at Peter confused and then looks at the tracker making sense of what Peter had just said. Tony knows that the ship works perfectly after all the test and is not surprised because he is a genius and he knows that. Peter then asks if they could look at what it is. Tony makes Peter aware that it could be dangerous but they go anyways.
As they arrive they see a ship that looks like a piece of crap and you could see smoke coming out of one of the wings. They stop the "Stark Destroyer" as Peter called it, in front of the other ship and they see a group of four people inside looking out at the ship.
They get out of the Stark Destroyer with their guard up and in their suits. When they enter the ship the people inside have their weapons drawn and there was also a raccoon with a machine gun.
"All right we won't hurt you if you don't hurt us"
"We sure as hell will hurt you if you don't tell us what you are here for" said some guy with masks with red eye holes and fluffy hair.
"Okay there was a little dot on our tracker thing and it wasn't moving so we moved toward it and- is that a cassette player?" Peter said with his spider eyes narrowing.
"Yeah" they guy in the mask says while nodding his head confidently "do you listen to the real music" he says referring to the 80's music I his "Awesome Mix"
"Sure, yeah" "my name is Spider-Man"
"Mine's Starlord"
Seeing that they are not a threat to each other they introduce themselves and Peter and Quill tell each other their real names and they begin bonding over the music.
" Great, another child to deal with" Tony says under his breath
"Tell me about it" says Gamora "I have four"
Rocket walks in with his gun and asks Gamora where she put his box of prosthetic limbs. Wondering why a talking raccoon would need a box of prosthetic limbs he feels her pain. Being the dad Tony is he is happy seeing Peter happy and taking about Earth, Wind, and Fire.
Tony helps the Guardians fix their ship and Peter and Quill hope that they can see each other again because Quill doesn't know what an iPhone is.

BoNuS:
"My name is actually Peter Quill."
Peter's eyes go wide and Tony immediately knows what's about to happen.
"NO WAY MY NAME IS PETER TOO"
