How it All Began!

Walking through the streets of a town called Jump City, we find a lone teenage boy. The boy in question looked to be about sixteen years old with tan skin, shaggy brown hair, and green eyes. he was wearing a black and green tee shirt, a pair of brown cargo pants, and a pair of green sneakers. He also had a sleek white wristwatch around his left wrist that had a square faceplate that was black with two green lines that made up an hourglass mark.

This is Ben Tennyson, or Ben 10 as he was well known as in the hero business. However, he wasn't feeling all that heroic at the moment. You see, ever since Ben's secret identity as a hero was revealed to everyone in Bellwood, he's faced quite a bit of prejudice for what he can turn into. Not to mention many ungrateful civilians were always pestering him about property damage.

His team and the Plumbers were of no help with these matters either. As a matter of fact, they were of no help at all! Really, the only two people that Ben could say ever had his back were his cousin Gwen Tennyson, and her boyfriend Kevin Ethan Levin. But they were away at college right now. Not to mention when he got back home, Ben had overheard his parents planning to kick him out of the house to fend for himself.

In light of these events, Ben snuck up to his room and packed up only the most essential things. Mainly his toothbrush, a few changes of clothes, and a couple of framed photos. The first one was of Ben and his cousin with their grandpa Maxwell Tennyson when they went on their second cross country roadtrip, and the second one was of the two Tennyson cousins and Kevin standing in front of Ben's favorite hangout Mr. Smoothy. And so, here he was just walking aimlessly through the streets of a place called Jump City. Ben was by no means stupid. He knew that he would eventually need to hunker down and find shelter.

It was an unfortunate turn of events that he forgot to bring any money with him. This meant that he couldn't stay at a hotel, so he just decided to find a cardboard box in an alley to try and get some shut eye. But as he was searching, he saw something off. Over by a pizza place, there were two girls that were definitely alien in origin smashing what looked like power suppressing cuffs against a concrete support beam.

One of the girls had dark orange skin that was by no means a tan. She had long, straight auburn colored hair that reached her waist, small eyebrows that were of the same color as her hair, and she was wearing clothing that looked like a combination of casual wear and armor. Her eyes were glowing with a powerful green energy similar to what one of Ben's aliens uses. She looked to be the same age as Ben, and had a figure that many girls her age would kill for.

The second girl looked to be the same age as the first one, if perhaps a bit older, and also looked like an almost exact replica as the first girl. However, her hair was black, her skin was lighter than the first girl's, and her eyes were radiating a more purplish black star energy. Ben guessed that they were maybe twins, but as of right now had no proof of such a thing.

Trying to stop the two were three others that looked to be around his age, however, Ben did notice quite a few differences with these guys. For one thing, he recognized the first teen to be a member of the Doom Patrol called Beastboy. Beastboy was about two years younger than Ben, had green skin that was a side effect of his meta human gene, along with pointy ears, green eyes that were darker than his skin, and sharp canine teeth. He wore a purple and black suit with a silver belt that was meant to transform as he did, but was designed to be absorbed into his body when he turned into an animal. He also wore a purple and black mask that had some silver trim. But to Ben, the mask was both unnecessary and ridiculous.

The next was a very tall and masculine african american boy that almost reminded him of his old friend, Manny. He was wearing a pair of black warmups, and a khaki hoodie. However, Ben could tell that much of that muscle was no longer natural due to only one thing. And that was the fact that his hood was down to reveal that most of his head was mechanical with silver and blue armor, and his left eye was a glowing red lense. Ben deduced that this guy was perhaps cybernetic.

Next up was a girl that was wearing a blue cloak with the hood up, a black leotard, blue shoes, and a strange red belt that hung diagonally around her waist. She had amethyst colored eyes, and ashen gray skin. Since her hood was up, Ben couldn't tell what her hair color was and right now he didn't care.

Without so much as a thought for his own life, Ben ran in to try and stop those two alien girls from bringing the building down on themselves and everyone else that was inside. Once he was just a few feet away from them, both alien girls took notice of Ben and just stared at him for a moment. They didn't really register him as a threat, and his threat level only decreased when he approached with his hands held in a "surrender" motion.

"Easy, now. I just want to help." Ben said.

That's when the black haired alien girl noticed something on Ben's wrist. Her eyes widened in surprise when she noticed what it was.

"Starfire, look at his wrist!" she ordered in her native language.

The auburn haired girl did as instructed, and gasped at what she saw. It may have had a new form, but she'd recognize the power signature of that device anywhere!

"Blackfire! Is that not…" Starfire asked.

"The Omnitrix! HE'S WEARING THE OMNITRIX!" Blackfire cried.

They were about to react violently to Ben, thinking that he was just there to harvest Tamaranean DNA for the Codon Stream. But that's when Blackfire noticed that she could now move her arms freely. She looked down at her feet to see that Ben had removed her inhibitor cuffs.

Her eyes widened in surprise as they stopped glowing, revealing them to be the same shade of purple as her fire. Why would a human who possesses the Omnitrix want to help them. Ben had just finished removing Starfire's cuffs, and now needed to ask a few important questions.

"There. Now that you're free, can you tell me who had you-MMF?!"

Ben was cut off when Starfire suddenly locked lips with him. The other teens were just as surprised by this action, but not Blackfire who knew what her sister was doing. After about ten seconds, Starfire broke the 'kiss' and Blackfire locked lips with Ben for the same amount of time. When they separated, Ben shook his head to regain his bearings.

"Whoa there, we haven't known each other for more than a few minutes and you're already kissing me?!" Ben asked.

"I do not know what you mean. Tamaraneans learn new languages through lip contact with other life forms. What is this 'kiss' that you speak of?" Starfire asked with a tilt of the head.

"Star, you may not have had the chance to study Earth cultures like I have, but surely you must know about how Earthling men and women show affection towards one another when they're dating." Blackfire said.

Seeing the blank look on her sister's face, Blackfire sighed and massaged her temples from the headache she could feel coming on.

"I blame mom and dad for not giving Starfire 'the talk'." Blackfire thought to herself.

"Starfire, when a boy and a girl kiss, it means that they are courting. But when a mother or father kisses their children, it's just a show of parental affection." Blackfire cleared.

Starfire was shocked by what her sister had just told her, but she really couldn't blame the Earthling for jumping to such a conclusion. After all, he knew absolutely nothing about Tamaranean culture to begin with! But before she could say anything, Beastboy realized just who was standing in front of them.

"Wowsers! You're Ben 10 aren't you, sir?!" Beastboy asked.

"What?! No way! That guy with the alien watch that let's him turn into alien superheroes?!" the mecha man asked.

Ben sighed since he knew the jig was up. But he wouldn't be able to tell them the full story of why he was in Jump city in the first place until he knew exactly who he was talking to.

"I think everyone here got off on the wrong foot. Maybe we should introduce ourselves first. You all know me as Ben 10, but my real name is Ben Tennyson." Ben introduced.

"Beastboy, former member of the Doom Patrol, sir!" saluted Beastboy.

"Just call me Cyborg."

"Rachel Roth. Just call me Raven." said the ashen gray skinned girl.

She pulled down her hood to reveal shoulder length midnight blue hair.

"We are known as Koriand'r and Komand'r on our home planet. But in your language, they would translate to Starfire and Blackfire." Starfire said with a light bow.

"Well, now that we all know each other, maybe you and Starfire would be kind enough to tell us what you're doing here on Earth." Ben suggested. "I mean, we don't get very many aliens away from my home town, Bellwood."

Blackfire looked down with her eyes glossing over due to unpleasant memories, and Starfire looked like she was gonna have a panic attack. Just then, a huge hologram of an alien that looked like a cross between a human and a reptile appeared over Jump City. And the guy did not look pleased.

"Attention, humans! I am Zarkon, leader of the Gordanian Fleet! Hiding in your city are two alien prisoners that are to be transported to our planet! You have three Earth hours to turn them in, or your planet shall be destroyed!"

As is to seal the threat, one of the bigger Gordanian warships transformed to reveal a huge photon laser cannon aimed right for the Earth! Ben and the others couldn't believe what they were seeing, or what they had just heard!

"You guys are PRISONERS?!" Cyborg asked.

"We're not prisoners!" Blackfire snapped. "They consider us prizes…"

That drew some confused looks from Ben and the others, so Starfire decided to elaborate.

"The Gordanians captured me and my sister during a war on our home planet, Tamaran. We are twin heiresses to the Tamaranean royal bloodline, and as such they plan on taking us to a place on their home world known as the Citadel." Starfire explained.

"What's the Citadel?" Raven asked.

"To be blunt; not a nice place." Blackfire asked.

Ben looked up at the Gordanian warships with a look of anger that could very well put Rath's to shame. He knew that he had to do something to help these two. He wasn't about to let the two of them be sent to a place that would treat them like nothing more than lambs to be slaughtered, and he'd die trying to protect them if it came to that conclusion!

"I had a feeling you'd be thinking to do something this crazy." said an elderly voice.

Ben and the others looked at a nearby crate to see an elderly Galvan standing there with a Polymorphic Crystal. Like all members of his race, the Galvan looked like a humanoid frog that was only about six inches tall, but he had wrinkly gray skin with a few liver spots here and there, and a few appendages on his chin and upper lip forming a beard and mustache. He also had bulbous green eyes, four fingers on each hand, and three toes on each foot. He was wearing clothing that seemed to be a combination of a Greek toga, and an Aztec battle dress with silver armor on his arms and legs.

"Azmuth? Why are you here?" Ben asked.

"You know this guy?" Cyborg asked.

"Who would NOT know him?! Azmuth is a member of the Galvans, and the smartest mind in five galaxies!" Starfire explained.

"Not to mention he's the one who built Ben's Omnitrix!" Blackfire added with stars in her eyes.

The elder Tamaranean princess had always idolized Azmuth growing up, and had wanted to become a great scientist like he was. However, she knew that she would never become as smart as the Galvan, but a girl can dream right?

"While it is refreshing to know that royalty knows of my intellectual ways, I am here strictly on business." Azmuth said, walking over to Ben. "This should help give you a greater fighting chance against those Gordanians."

Before Ben could question what Azmuth was talking about, the Galvan opened up the core to the Omnitrix and inserted the Polymorphic Crystal. After closing off the core, the Omnitrix began to glow a bright green color and started to transform. It shifted from his wrist to his hand, and became akin to a fingerless gauntlet.

It looked a lot like Albedo's Ultimatrix, but there were some minor differences. Instead of being red with black squares on the knuckles, Ben's new Ultimatrix was a metallic gray color with one black square on each knuckle. There were three glowing green lines that went between the knuckles, and the dial was silver with a green hourglass. It beeped and flashed a few times as it finished transforming.

"An Ultimatrix? But why?" Ben asked.

"For two reasons. One; I felt you were ready to handle the power of the evolutionary function of an Ultimatrix. Although I hate to admit it, Albedo was a genius when it came to weapons development. And two; I agree with you that these Gordanians must be stopped! And with this team of young heroes by your side, I know that you will be able to defeat them! Good luck, Ben. Oh and before I forget, there are also a few new Ultimate forms for you to use in that new Ultimatrix." Azmuth explained.

And with a flash of light, Azmuth left for his lab on Galvan Mark II. Looking back up to the gordanian ship, Ben knew exactly what they had to do.

"Well guys, it looks like we have a common enemy. I say we team up to take them down, and protect the Earth and everyone on it from this threat!" Ben declared. "So what do you guys and girls say? Team?"

Ben put a hand out as a show of cooperation and companionship, silently hoping the others would do the same. Looking determined to stop this new threat, the others put their hands in as well.

"Team!" they said in unison.

"So what's the plan, boss?" Cyborg asked.

"We go to the ship with the big gun, we take it out, and take down their leader! That should in turn drive away the rest of the fleet." Ben explained. "Any objections?"

Everyone shook their heads no. It was really the only plan they had, so what else were they supposed to do? Ben activated his new Ultimatrix, and slammed down on the core. In a flash of green light, Ben transformed into…

That's all I've got for now. But I hope you all enjoy the first chapter of this story idea! And if any of you have any ideas as to a new look for Ben, let me know! I'll be accepting ideas until I post the third chapter. Read, review, and enjoy! All flamers will be fed to Trigon!
