O.P chapter 1 - Gamora

A.N: Hi guys. A short while ago, I posted a poll for which story I'd do next. One of the options was an OC arriving in the marvel universe with Ben 10's omnitrix attached to his wrist. This idea was based off of the phenomenal fanfiction story 'Dial'. Now, the story wasn't chosen but I sincerely hope to write it in the future. One idea I've come up with is a collection of short stories (kind of like my test chapters) where I write him with different potential love interests for the fic. Not supposed to be quality content, just a little time pass and making some ideas for a potential fic. Pairings will mostly be from Marvel but one of my ideas for the story will involve the multiverse so I will also be posting some characters from other fandoms like Elastigirl from Incredibles, Starfire from DC comics or Thalia Grace from Percy Jackson. Basically anyone who I think could potentially work as a good pairing for the story.

Any pairing suggestions are welcome, I plan to post this in between stories (mostly when I don't have too much time to write). Hope you enjoy the chapter. For this first chapter, I'm going to start with Gamora of the Guardians of the Galaxy. This story's name will be OP (short for Omnitrix pairings) and the chaacter's name in this fic will be Harry, simply because I'm honestly just used to writing the name 'Harry' in all of my fics, if I ever truly write this story then I'll probably come up with a different name. Hope you all enjoy.

Chapter 1 - Gamora.

Scene 1:

"Okay, got to admit, this was not how I thought that this would work out." Harry thought out loud as he walked down the hallway of the prison he was in.

The last few days had been a bit of a rollercoaster for him personally, more so than the rest of the year had already been. It started when Loki, Thor's evil brother, decided to invade the Earth. Harry had joined the Avengers in fighting him off, along with his invading army from outer space. And then at the end of the battle, he ended up being shot off into space, where he arrived on some random planet in the middle of space where some tall blue woman tried to squash him between her thighs for some reason. He managed to escape and ended up on another planet, where he managed to spot a fellow human, a man he would later learn was named Peter Quill. He was fighting a beautiful green skinned woman, who he would later learn was named Gamora. Harry had went to help when Rocket and Groot (a talking racoon and tree) decided to jump in and soon all of them were arrested.

Harry wasn't the biggest superhero nerd in the world (even though he wished he was), mostly because cartoons existed as a kid and by the time he took an interest in comic books, his parents didn't want to buy him any, so his superhero knowledge was limited. But he still knew quite a bit, which had helped him so far. He knew he was in some version of a world based off of Marvel superheroes, the people who he was walking with weren't just any ordinary aliens, they were the Guardians of the Galaxy, only they didn't appear to have even met each other before today. Which kind of sucked as all they really had done was fight each other and then get arrested, along with him, which was why he was now walking down the hallway in handcuffs along with them. His own cuffs had been designed so they covered the omnitrix completely, preventing him from transforming.

"So, want to tell me what exactly all this was about?" He asked the others as they walked.

"It's simple, Human," Rocket snorted. "Groot and I were on the way to a very nice payday when you put your ugly face where it didn't belong and interrupted."

"I could have escaped the pair of you," Peter said in an amused voice.

"I am Groot," Groot replied gruffly, earning a barking laugh from Rocket.

"Yeah, Groot, you're right." Rocket cackled.

"Anyway," Harry ignored him in favour of speaking to Gamora who was walking in front of him. "What about you? What's your part in this?"

"I don't see how that's any of your business," She said at once, not even turning back to look at him. "You interfered in my matters without even knowing what I was intending to do."

"I saw you try to steal something from a fellow human, I wasn't about to let that slide," Harry replied easily.

"Appreciated," Peter spoke up. "But something tells me you're no ordinary human. I mean, I haven't been on Earth in a long time, but I'm pretty sure that we can't turn into giant furry dogs."

"It's a speciality of mine," Harry replied as they stopped at a checkpoint, the guards grouped together to discuss something. Leaving Harry free to lean forward so his head was right behind Gamora's. "I'll make you a deal," He whispered. "Get these cuffs off of me, and I'll get you out of this prison." For the first time since they got here, her head spun around, and she looked at him. 'Why do all the dangerous women have to be hot?' He mentally wondered.

Scene 2:

"I need to get this straight, I leave Earth for a second time to find you guys and I barely get time to take a shit before I have a whole army chasing after us?!" Harry blurted out, holding tight to the chair in front of him as he stood in the cockpit of Milano, Star Lord's ship. Rocket and Quill were copiloting the ship as it dodged, ducked and dived out of the way as what appeared to be a few dozen ships chased after them.

"At least we ain't boring!" Peter said as he blasted one of the chasing ships with the ship's cannons. Many of them tried getting past them and were blasted straight away. Drax laughed as the ship blew up, the alien warrior stood next to Harry and watched with great interest while a baby version of Groot played with his ear.

"We can surely fly faster than this!" Harry pointed out.

"We can't," Drax told him. "The batteries are unstable, they'd explode."

"Explode? Batteries? What batteries?" Harry asked quickly.

"The ones Rocket stole, that's why they're chasing us," Drax explained.

"Dude!" Rocket said whilst grappling with the steering.

"I mean, no batteries, there are no batteries here," Drax said quickly.

"Screw this, I'm going to go out and blast them then." Harry decided, turning around and walking down to the ship's hanger where he saw Gamora standing along with her captured sister, Nebula, who was tied up. "Hi Gamora, hi Gamora's murderous sister," Harry said casually as he stopped in front of them. "Can you open the drop zone, please?" He asked Gamora.

"What's the situation upstairs?" She asked as she pressed some buttons on the side.

"Rocket messed up, and we're still getting chased by hundreds of ships. I'm going to blast a few." He explained as a glowing blue circle appeared behind him, the circle flashed and suddenly became transparent with a blue sheen over it. "So, what's new with you?"

"Currently dealing with my crazy sister," Gamora explained with a shrug as she walked over to him, ignoring Nebula as she spat out a rather rude curse. "Yourself?" She asked, stopping in front of him.

"Dealing with the dramas of my planet," Harry sighed as he activated his omnitrix, the green hologram appeared and he circled through it until he found the one he wanted. "It's good to get away. I'm glad I've got to see you again."

"Same," Gamora smiled up at him as she stepped in closer. "You're a valued ally,"

"Oh, is that all?" Harry asked, smiling back at her.

"Wouldn't you like to know?" She smirked before pressing down on his Omnitrix. A green flash enveloped him just as she pushed; he fell through the blue circle and out of the ship, his body transforming as he did so. What was once human was now a red, humanoid, manta ray-like alien with green eyes. He had black outlines on his face, yellow horns extending from his nose, gills underneath his arms and yellow patagia.

"Jetray!" He cried out before flying towards the ships, dodging and ducking as he started blasting them to pieces.

Scene 3:

"Peter," Gamora's voice called.

"Come in," Peter said, sitting up on his bed and removing his headphones. Gamora walked into his room, ignoring his nude posters and general mess with ease of practice, she stopped in front of him.

"Peter, I have a matter I need your assistance with," She said, taking a deep breath as she sat down next to him. "You are an expert on Earth matters, right?" She asked, staring at him.

"What? Oh, yeah, yeah," He quickly agreed. "I lived there for years. Don't mean to toot my own horn, but I know my stuff."

"Hmm, would you say that I am...' attractive' by human standards?" She asked, leaning forward slightly.

"Um...I...yeah," He said, his face flushing slightly as she got closer.

"And you know exactly how a man would approach a woman on Earth?" She asked, leaning even more forward. "A woman he was interested in?"

"Oh yeah," He breathed out as he stared at Gamora. For the longest time, he thought that she was out of his range for a long time. The girl just seemingly wasn't interested in him, which was vexing, as he never really had problems with flirting with girls. But now, it appeared she was changing her tune.

"Then I need your help," She said in a low voice. "Harry slapped my ass," She said suddenly.

"Wait," Peter blinked, leaning back and staring at her. "What?"

"He slapped my ass," She repeated. "I need to know, how do I get him to do it again without him knowing I like it?"
