The Answer AU - Star-Lord x Gamora ( completed)

Chapter 1: First meetings and encounters

"Titan- 50 years ago"

Thanos gathered his army around the battlefield sitting on his throne, deviously, so far things were getting quiet at first he but at this point he sensed a war to occur. His Adopted Daughter Gamora  stepped forth to his presence appearing in her uniform "Gamora, I am impressed with your combat, tell me, " He asked demanding her " Did you see anything during your training?", The assassin responded "I remember one of the guards reminding me about our preparation for the battle, no matter what it takes I'm willing to take it", Thanos smiled with impress "Glad to hear it, Now go with the other guards and don't let anyone get in your way", "Yes father" She obeyed leaving the room.

Meanwhile, Peter Jason Quill was searching for the infinity stone from being sent by Yondu and the Ravengers. The planet was quiet but too quiet, The cold breeze and dark silence was quite unsettling for comfort by the appearance of the location.  Yondu suddenly calls him out on the tracker in his mask "Quill, do you read me?", "Yes, I can hear you perfectly, encase you're wondering if I've found the infinity stone yet so far no", He looks around the pathways to see if there was anything behind him "What do you mean you haven't found it yet?!" His leader yelled loosing his patience. "Let me finish dammit" Quill Complained "It's kind of hard to concentrate in these conditions on this planet, from the looks of it in my perspective finding this infinity stone is like finding a needle in a haystack, What should I do now?". Yondu answers him "I don't care if you can't find it, Just figure it out!". 

2 hours later, Peter was busy focusing on the mission, so he decided to remove his mask and just as he was about to pull his gun out. a mysterious figure swoops past him causing the gun to fall out of his hand, it happens again but he suddenly gets hit in the face, knocking him out on the floor, Peter trembled slightly trying to get himself back up again "Who are you?, show yourselves!" suddenly Thanos's Assassins charged by, one of them snatched Quill's gun, he turns quickly "Hey!, give that back!", The Assassins shift past him causing him to have a couple of cuts on his face, he groans holding his left cheek so he quickly gets his spare gun out of his pocket "You want to fight fire with fire?, then I accept" he pants, attempting to dodge their attacks.  the first encounters tried to tackle him, Quill grabbed one of them and body slammed the assassin on the ground, Suddenly Gamora charges up to him and kicks him violently causing him to slam into a wall as she stepped towards him "Are you finished yet?" She responded glaring at him threateningly aiming the the tip of the blade against his neck. "Damn she's tough" Peter thought staring at her nervously as he's trying to move away from the blade but since she looked demanded for his response he replies "Me?, Never I'm just warming up" She interrupted him "State your purpose!", Quill stammers slightly "W-Well em.....I was sent here to search for something important" , She started getting more intimidating with him "Tell me, what are you looking for?!" but He refused to tell her because he knows if he told anyone and especially an assassin about the infinity stone, he'll be done for.

Just as he was about to explain to Gamora, Yondu suddenly inter veins through the communicator "Quill, what the hell happened?!" but Peter interrupts him whispering "Yondu, Now's not the time", "What the hell are you talking about boy?!" Yondu yelled, Quill quickly tries to mute the speaker from his ear, before he tried to explain but Gamora known what was going on "You can't lie to me,I've seen what your capable of now, your purpose has something to do with those infinity stones", He was shocked but before they were about to fight, it gets interrupted by an occurred explosion, "Surrender now, or We'll go easy on you!" said the voice in a distance, Thanos suddenly looked upon the distance recognizing the voice, in the smoke appeared a red and golden person in a iron suit known as Tony Stark also known as Iron Man as three other people are behind him, Steve appears holding the shield beside him asking him "Tony, what's your plan?", He looks around "Well Captain, you and Banner take care of Thano's guards while I take care of Thanos", Thanos was furious as he beckoned "New plan, go and get that infinity stone and cease this criminal and The Avengers!".
