It's been quite a while. I had this story idea for about two months and never knew if I should consider it for a full story. This one I am excited to attempt in blending a variety of story arcs with the different heroes. The heroes won't be bind to a single universe canon and will use several like the Arkham Series and other canons. If I'm not writing a chapter on my Avatar/ Ben crossover, I'm writing for this story and I hope you like it.

Ben's Omnitrix will also work a little more like Ultimate Ben's version though he won't need to transform into his ultimate form.

A New World

Bellwood hasn't changed in the last five years. That leaves a lot of crime fighting in the hands of Bellwood's, Earth's or the Universe's mightiest hero, Ben Tennyson. Though, the crime fighting hasn't been as…high stakes as the past.

"Are we doing this same song and dance, Zombozo? Been awhile, I thought you retired." The clown from hell was on a tear throughout the city; with an army of zombie clowns now at his disposal and the new experimental clown gas now tested and approved by the frantic clown himself! Now, he was ready to take his show global.

Well, that was until he certain green jacket, brunette, and green-eyed hero came across the clown's gaze both at a stare down on Bellwood's main street. Their gazes were on even eye-level showing the young hero gained some height. Zombozo opened his mouth sporting a tooth-decaying smile.

"I had a little vacation, my boy", Ben could see the nightmarish clown revealing a closed vial of some green liquid, "and you should enjoy a more…permanent vacation." He threw the vial at the hero's direction with the green liquid quickly changing its molecular structure into a gaseous state heading straight at Ben.

"You never learn, Zombozo", he said with confidence showing the Omnitrix on his wrist. The watch had a new look after all those years ago; it had more of a retro look seeing the alien hero wanted to have a reminder of where he came from all those years ago. Of course, that didn't mean its functions were retro.

Terraspin. That single thought resonated with the Omnitrix enveloping the hero in a lighter emerald glow, not enough to blind a person like the original Omnitrixies would, but still enough light to make his transformation known.

Transformation…may not be the right word either. Zombozo felt a strong gust of wind repelling the zombie gas forcing him to shield his eyes from its intensity only to see the brunette wasn't even in is Geochelone Aerio form. He was in his regular human form.

Ben enjoyed seeing the awe-struck nature the sadistic clown, snickering at him. Luckily, for him the show wasn't over just yet.

"Grr! Fine! If I can't make you like your fellow citizens, then I would command them to destroy you!" With that declaration, the zombie clowns sprinted like a pack of rabies-induced animals. Ben didn't look fazed one bit at the new development.

Gutrot. The pack of zombie clowns was at a hand reach from clawing at the young adult until they suddenly stopped at their tracks and fell unconscienced. The climax, the fall action, was so…surreal in Zombozo's eyes.

"If you're wondering why they are unconscienced, slowly turning back to normal, and I'm my regular human self, it's because of my new Omnitrix. I no longer need to transform directly into my aliens to gain their abilities and Gutrot has gotten a few upgrades like being able to expel gases that aren't noticeable to the naked eyes. Pretty cool, ah?"

Zombozo fell to the ground speechless with his only instincts was to run as fast as possible. He quickly picked himself up and bolted the opposite direction giving out a frightened scream.

XLR-8. Not wasting any time, he appeared right in front of the criminal blocking his only escape route forcing him to surrender in fear. Now all they should do is wait for The Plumbers to reach them and complete the arrest. It was the longest ten minutes of his crime fighting life.

"This city never changes. What do you think?" Ben lowered his gaze at the defeated Zombozo currently tied from head to toe. Boredom was setting in waiting for his team as he was trying to strike a conversation. Not having the decency to give a response, Ben just huffed and continued, "I wonder if there still are places in this universe that really needs a hero."

The heavens answered back as a portal suddenly tore the fabric of space-time. "Wait? What?!" He got his answer as it started sucking the unexpected adult leaving no room to utter any more last words.

Zombozo seeing the unexpected turn of events stood there in a long silence until…

"Now…that no one is watching…", he bolted leaving onlookers hearing the squeaking sounds from his clown shoes. The Plumbers arrived on the scene tasked with the transportation of the hardened criminal to appear on the scene just as baffled at the absence of the criminal and the alien hero.

…

"AHHH!"

The blue swirls of the portal were all the hero could see as he felt his body pulled by an intense force. He eventually found a white light at the end of the tunnel or portal and started to see the color of white.

He realized too late it was the color of the floor as he fell, front torso first, causing him to groan in pain. Luckily, the portal didn't drop him too fast or else, he wouldn't have a very good first day in this new world.

Then again, it was too soon to say it wasn't going to be the worst day in this world. "Intruder Alert!" A booming tone, yet still femininely, yelled most likely to alert the other inhabitants in the building while he was starting to be surrounding by these colorful group of people.

He finally saw who was the woman who gave the alert and found…she was rather beautiful. She had long flowing black hair, and wore a body suit that will eat Uncle Sam's heart out with the bottom sporting the blue color and stars while the top was red mixed with gold. She also had a golden red-star tiara and metal bracelets. The adult hero couldn't also forget her long legs and…assets.

"Who are you and how did you manage to enter the Justice League Headquarters" a deep voice sounding more like a command than a question broke his trance over the woman. He turned his head slightly to see a muscular-fit man sporting a black body suit along with a cape and…is that bat ears on the top?

His curiosity over the man stopped short after feeling a sense of constriction around his body. Ben saw the object looked like a lasso cowboys would use to catch their cattle. Like everything the woman wore, the lasso looked like it was made with quality in mind.

"My Lasso of Truth will compel you to answer our questions whether you like it or not", the woman said with conviction.

The brunette shrugged not enjoying the air of hostility, "I don't mind. I have nothing to hide. Ask me anything." Batman and Wonder Woman were taken back at his carefree nature looking at him with caution.

Bruce Wayne started the interrogation, "Who are you and where did you come from?"

"My name is Benjamin Kirby Tennyson and I'm a hero back in my dimension."

The two looked at each other with Wonder Woman asking next, "How did you come from another dimension?"

"I came from a blue portal sucking me in from my dimension and dropping me here…rather forcibly if do I say myself." The duo continued the interrogation alternating between each other.

"You said you were a hero back in your dimension?"

"Yes, I am the hero who wields the Omnitrix", he began fidgeting trying to direct them to the watch on his wrist, "It's a device which allows me to harness the powers and abilities from different aliens and it has helped me a lot. I have save my dimension from alien armadas, doomsday devices, evil twins, and even recreated the universe after the first one was destroyed by the Anihilaarg!"

The duo looked at each other with their mouth shut, but mentally, they were open jawed by the brunette's tales of adventures. It wasn't only those two, but the rest of the that came hearing the distress as they, too, were hearing the stranger's tales.

Diana couldn't believe the tales coming from the man's mouth, but they were all true. If he would have attempted to lie, he would have showed signs of the Lasso forcing the truth out of him, and he just said it so matter-in-fact like he did all that last Monday.

She was the first one to make the judgement and released the young man from his lasso thanking her with his benevolent smile. She couldn't figure out, but his smile seemed to strike a chord in her, feeling a small flush on her face.

"Let me introduce us. I go by the name, Batman, and I'm one of the founders of the organizations known as The Justice League and we are currently at the Justice League's Headquarters." Justice League? His green eyes looked and saw a spectacle he has only saw in other badass headquarters. He lunged looking out at the wide window displaying a view Grandpa Max, Gwen, Kevin, and himself as seen before, but it still felt incredible.

"Whoa! Your headquarters is a satellite in orbit!" He looked through the glass seeing the planet Earth at this breathtaking view. At least, Earth looked as similar as back home.

"And I'm Wonder Woman. It's nice to meet you." Diana moved next to window offering to shake the ecstatic adult which he happily obliged. "It's nice to meet you too."

The next hero came in a blur through Ben's eyes which surprised him. "Hi! I'm the Flash. It's nice seeing a new hero." The man took the initiative and shook Ben's hand initially startled but then impressed at his magnificent speed. Ben could see he was all speed and all cool seeing his red jumpsuit and lightning symbols over his attire.

"Wow! You're fast. I may have an alien that I can race with."

Flash was pumped up hearing a challenge, but he was always confident he was the fastest man or alien alive.

"Cool watch! Mind if I get a chance to examine it. My name is Cyborg by the way." The next hero the brunette notice was half-man and half robot and it was impressive. Ben notice his enthusiasm over the watch and backed away slowly.

"Sorry, Cyborg, but this watch was engineered by me using the brightest aliens in my arsenal, and I don't have complete confidence I can fix it if something goes wrong." Victor was a little distraught by Ben's rejection, but he honored his reasoning.

The heroes of the Justice League soon made room for Clark Kent as he shook Ben's hand. "It's nice to meet you, Benjamin Tennyson. My name is Superman and would you like a position in the Justice League. We are the foremost defenders of universal threats."

"You can call me Ben, and Yes! I want to join you guys!" Finally, Ben Tennyson has found another hero organization and they weren't The Galactic Enforcers. This was amazing! Batman was the next to speak making sure not to get the brunette's hopes all that high.

"Before we decide to allow you in the Justice League, first we need to test your powers and abilities."

Ben was already liking it. He could use some serious alien hero training, and he can see all these heroes were no pushovers. Diana hearing the chance to test the young adult's abilities was ready to throw her tiara in the ring, but…

She wasn't the fastest.

"I'll go!" The Flash zipped past the Amazonian princess who was revealing a pouting face, and appeared right in front of Superman and Ben. Ben immediately accepted the challenge as the heroes made their way to the sparring room.

…

"Think you can land a punch on the fastest man alive?"

"Think you can land a punch on the multiverse's most versatile hero?" Ben retorted cracking his knuckles getting a nice smirk from the speedster. With the countdown beginning to initiate the match, Ben was beginning to glow a light emerald color.

Fasttrack. The spectators notice the subtle emerald light and looked with anticipation with Bruce Wayne looking with the most vigilance at the alien hero.

The bell chimed as both heroes sprinted at each other striking with their elbows, but both were blocked by each other's. The members of the Justice League looked with amazement with Ben's comparable speed against Flash. It was starting to make some sense; these aliens were channeling to his human body granting him their abilities after seeing Ben's extreme speed.

Both were keeping each other first strikes at bay. Wally was starting to get heat up after seeing his first strike blocked. "Not bad for a new guy."

"It's all skill." Ben attempted to make his point by pushing Flash's elbow down creating an opening for the alien hero to land the first punch. Moving one foot forward he lunged at the Flash with his fist aimed at his face.

Got you! ...What!? Ben's fist hit thin air as the hero lost sight of the Flash. A beat of sweat could be seen on his face realizing the worst as he saw Wally reappear right in front landing a devastated strike on his torso.

Ben's reaction time didn't allow him to even raise his arm to cushioned the punch. That was how fast his adversary was! Ben collided with the wall of the sparring room losing all the air in his lungs.

Cyborg, Wonder Woman, and most of the Justice League felt sympathy over Ben's injury knowing full well of Flash's strength augmented by his speed even if he was moving at a fraction of the speed of light. That is still a lot of energy going in a punch.

Diana was about to call the match until he saw Ben pick himself back up spitting to clear his throat. She could see the alien hero going in a sort of Zen mood as he inhaled deep breathes getting in much needed air in his body while another emerald light glow around his body.

Flash notice the green glow and proceeded to lunge again aimed at the same spot hoping to defeat the young adult hero in one more strike. To Wally, time felt like it stopped as he can see the lack of motion from Ben knowing full well he could never out speed the fastest man alive.

True. No matter what alien in Ben's arsenal, he could never match Flash's super speed because of his speed force and faster than light capabilities. That didn't mean he wasn't at the mercy of time itself.

"Looking for someone?" Wally was wide-eyed. No way, he was right in front of me! Ben was frozen from his perspective so how did he get behind him?! Wally quickly u-turned and took aim at the grinning hero again seeing him disappear from his sights.

"What's the matter? I thought you were the fastest man alive?" Flash felt Ben's punch land on his chest knocking the air out of the unexpected superhero. It was only the aftermath did Wally realize something. Ben's punch didn't pack as much force as he exerted in the first few seconds in the match and the only reason Flash's air was knocked right out was because of the suddenness and surprise of Ben's newly gained speed.

The rest of the Justice League didn't know about this revelation and instead were all in awe over Ben's sudden superiority of speed over Flash's. Batman, Wonder Woman, and Superman, the three founding members of the Justice League, were the most surprise. Batman wasn't only surprised, but was also very suspicious over the stranger's true potential and needed to gain more insight about the new hero. It's better safe than sorry just in case if Ben would betray them.

All spectators were glued to the fight. Ben and Flash kept their fist fight with Ben unleashing punch after punch against the speedster while Flash couldn't hit the blind side of a barn.

Ben was getting extremely nervous. His punches weren't getting the results he needed and if things become a war of attrition, he would stand no chance against the speedster. He could start feeling the effects of utilizing the alien DNA far too long, and Clockwork was a very demanding alien all in itself. If he switches to another alien to save on energy, then the Flash would wipe the floor with him, but if he stays in this transformation then who knows how long he has left.

Suddenly, he felt intense pain coursing around his torso, "AHK!" Ben quickly deactivated his Omnitrix while he kept coughing rather intensely. Flash notice this too and stopped the match with the rest of the Justice League looking with concern. Diana was the first to act checking his vitals hoping it wasn't anything serious.

Luckily, it didn't last long, and instead started to subside a little after deactivating the watch. "Hey man, are you going to be ok?" Wally placed a hand on his back in attempt to ease the pain. Ben raised his head and had a rather forceful smile still feeling the aftereffects, "Don't worry, I'm fine. I don't have much time with my new Omnitrix so I need little more practice with it."

Wonder Woman and Superman escorted the new hero to the infirmary making sure there was no hidden consequences as everyone started to get back to their duties. Batman was going to need some time to scrutinize the visual and audio feed on the sparring match. How much are and are not telling us, hero?
