Summary- Things hasn't been good for Ben lately. But his life will take an unexpected turn when he's sent to other dimension. The DC earth.

This is my first try at writing a multi chaptered story. Plus, I'm starting in my college. So updates might not be regular. But there will be updates.

I don't know much about DC universe except from what I've seen in JLA cartoon and some basic facts. So some facts might be wrong. I apologize. But I'll try to remain as correct as possible.

Disclaimer- I OWN NEITHER DC NOR BEN 10. But if I did own Ben 10, Ben would be lot like he's going to be in this story.

English is not my first language. It isn't even my second. So, I apologize for grammar and spelling mistakes. Feel free to correct my mistakes in your review.

This story is rated T. There will be some swearing, nothing too serious. Also, there will be some graphic fight scenes.

First of all, I'd like to give a shout out to the author who inspired me to write this. Sandman7734. I'd try to keep this fic as different from his as possible.

To make it clear, Ben is 19 in this fic. He looks like his Ultimate Alien version, only taller and more muscular(kind of like Nightwing). This takes place almost 3 years after omniverse. JLA timeline is end of season 2.

Chapter 1: Arrival

Mr. Smoothies was a lot less busy than usual. There were hardly any people in sight. Sounds of birds chirping in nearby park could easily be heard over the swift breeze. The calmness of the moment was broken by the arrival of a black green car. The driver, a young man, clad in black T shirt and brown jeans started to make his way to the booth. He had a sunglass on even though sun didn't really demand it. The world knew him as their greatest hero- Ben Tennyson.

"The usual?" asked the girl on the booth.

"The usual." Came his simple reply.

Normally he would've talked to her. Asked her about studies. About her younger brother. Normally. But that was hardly a normal time.

Ben took his usual spot. Some other people who were there gave him a glance and looked away. Normally they'd flocking towards him. Normally.

He took off his sunglasses revealing his green eyes. Eyes that were surrounded by dark circles. He hasn't been sleeping much. It's hard to sleep when every time you close your eyes, you're attacked by nightmares.

Ben took a gulp of the smoothie and allowed the sadness to take over him. It was all his fault. It was his fault he was sitting here alone. He was supposed to be somewhere else. But he was too much a coward to be there. He was not ready to say goodbye to her. Not yet. Gwen might have died that night, but he won't let go of her until he had avenged her. Until he had his revenge. By taking him down. Aggregor.

Just then he heard a group of people shouting and heading towards him. Reporters.

"Mr. Tennyson. How was the funeral?"

"Are you going after Aggregor?"

"Is it true that Kevin Levin has sworn revenge on you?"

"Are you single?"

The last question was enough to break the dam of rage filled in him. Ben looked at the reporter who's asked this, a blonde woman, and was standing in front of her in less than a second.

"Am I single? AM I SINGLE?! THAT'S WHAT YOU WANT TO KNOW?!"

Completely taken off by his outburst, she was pale as a sheet. Before she or anybody could react, there was a green flash and Ben was gone in a blue blur.

"That went well."

Later that night…

GWENDOLYN TENNYSON

Daughter and Friend

That's what her gravestone read. It was a pink marble. For some strange reason, that brought a smile to his face. His smile soon changed into a frown. In a flash of green light, Ben was replaced by a tall purple creature which he called Chromastone. He bent on his knees and touched the grave stone in a particular pattern. Satisfied, he stood up. Ben transformed back with another flash of green light. The gravestone now read-

GWENDOLYN TENNYSON

Daughter and Friend (and Sister)

All the strength, all his resolve to not cry left him that instant and he bent on his knees sobbing.

"I'm sorry. I…I should've been there. Its…all my fault."

"Truer words have never been said before, hero."

Ben's neck snapped with lighting fast speed to the source of sound. He never thought he was capable of hate. He didn't like Vilgax and Harangue irritated him at best. But seeing him standing there with a cocky grin on his face, he felt nothing but pure hatred towards the osmosian.

"I had a feeling I'll find you here. Decided to finally pay her a visit?" asked Agreggor, his grin never leaving his face.

Before Aggregor could even react, Ben placed a well aimed kick on his knees followed by a punch to his gut. Even with superior durability, Aggregor was on his knees in a second. Not stopping for a second, Ben kicked him on his face and was very much satisfied when he heard a crunch sound.

For the first time, the grin was absent from Aggregor's face.

"Been training, I see. Who's been training you? Your sister?"

"Don't talk about her! YOU KILLED HER!" Ben was trying very hard to keep his anger in check.

Wiping a little blood from his nose, Aggregor stood up and said, "Did I?"

Ben, who has grown a good deal in last year, was still some inches shorter than the osmosian.

"Give me one good reason why don't I kill you right here, right now?" Ben asked, meaning every word of it.

Putting his cocky grin in place, Aggregor replied with a tone of superiority, "How about, you can't? You couldn't stop me last time and you're not going to be able to stop me this time."

"I won't bet on that." Ben said activating his omnitrix and popping up the logo of Diamondhead.

Aggregor just looked at him making no move to show that he was threatened.

"I am not here to fight. But I don't know about them." With that said, Aggregor disappeared in the thin air.

Ben didn't have much time to ponder on his sentence before he heard a blaster fire from his behind. His plumber training kicked in and he ducked to the ground to dodge the laser which passed harmlessly over his head. Several other lasers were fired in his direction which Ben dodged with expertise.

Forever Knights. Ben thought bitterly. Agreggor had allied with them recently which were a very big surprise since they hated anything alien. Even though Ben couldn't see them, from the laser fires, he guessed there were four. Maybe more. Some might be hiding for a surprise attack. They knew better than to underestimate him even when he was not transformed. Twisting the dial of the omnitrix, Ben selected his desired alien and slammed his hand on the dial. In a blinding flash of green light, a hulking red, four armed creature, Four Arms, was standing in the place of Ben. With surprisingly fast speed for his size, he lifted a knight with one hand and threw him at another knocking both of them out cold. Four more knights came out of their hiding. Ben, in no mood of playing games, took a deep breath and brought all his four hands together for a thunder clap. Shockwave produced threw all four knights to a very good distance, instantly knocking them out. 2 left knights, not used to seeing Ben being this brutal in his tetramand form, decided to retreat. Ben, sensing their motive, lunged at one of the knight who was about to activate his teleporter. In mid air, Ben transformed into Upgrade and quickly covered the Knight. Trying to stop the ongoing command of teleporting them all to their base, Upgrade did nothing but upgrade the teleporter. The teleporter which was meant to teleport to only 20 mile radius, teleported the merged Knight and Galavnic mechamorp to far far away than they'd imagined.

The first thing Ben noticed when he gained his senses were that it was no longer night. And he was not in the graveyard. And he was sleeping in an alley. Getting up quickly, Ben looked everywhere and found nothing but a stray kitten eating from the dustbin. He got up and followed to the road. Seeing all those tall skyscrapers, he concluded one thing- He was not in Bellwood.

Ben tried to remember the last thing. Upgrade, the Knight and teleporter. Great. He was now in New York or something. He must have passed out after the teleportation and the Knight must have escaped. Strange that he didn't try to kidnap him when he was unconscious. Never the one to pay attention in geography class, Ben had no idea which direction Bellwood was. So he decided what any lost person would do. He called home. Popping up the dial of his omnitrix, he tried to contact the plumber station. All he got was static. Confused, Ben decided to call home only to realize that he had left his phone in car. He sighed. Getting out of the alley, the first thing Ben noticed was a huge building with a huge globe on the top of it and The Daily Planet written on it.

Newspaper? He thought. He had never heard of it though. Then again he didn't know many things.

Ben, worried of being recognized here decided to put on his sunglass (which somehow has survived the whole ordeal). He saw a man in blue suit and decided to ask him for his phone.

"Um.. Excuse me. I need to call someplace urgently and I seem to have misplaced my phone." Ben said, slightly modifying his voice.

The man looked at Ben for a second and gave him his phone.

"Sure." He said smiling, adjusting his glasses on his nose.

Ben took the phone and dialed Grandpa Max's number. Apparently the number was not available. He dialed his mother's cell. Same. Frustated, Ben called his father and was relieved to hear a tone. After 4 rings someone picked the phone.

"Hello? Who is this?"

Ben didn't expect to hear a female's voice on the other end.

"Umm.. May I talk to Mr. Tennyson?"

"Who?"

"Mr. Tennyson. Carl Tennyson. The one who this phone belongs to."

"I'm sorry dear. But there is no Mr. Tennyson here and this number belongs to me."

Thinking he might've dialed wrong, Ben apologized and disconnected. He checked the last call and the number was his father's. Growing more and more frustrated now, Ben decided to call his mother again when the man standing in front of him spoke.

"Everything okay, son?"

Ben looked up at him and nodded.

"Yeah, everything is all right. Here, your phone." He said handing the phone to the tall guy. Deciding to stop hiding himself and ask this guy which direction Bellwood was, Ben took off his sunglasses. Ben expecting a look of surprise to pass on the man's face, didn't expect him to just turn and start walking away. Confused by his behavior, Ben called him.

"Hey. Mr…"

The man turned back and said, "Kent. Clark Kent."

"Mr. Kent. You don't know me?"

The guy arched his eyebrow.

"No. Should I?"

Getting more and more confused, Ben asked a question which he hoped the man could give the answer to.

"Which city is this?"

A look of concern passed over the man's face.

"Metropolis. Are you lost, son?"

Metropolis? He knew his geography was not that good, but he had never heard of Metropolis before. Seeing that the man was waiting for him to reply, he shook his head. This was not good.

"Are you sure you don't know me?"

This time the man seemed to actually try to remember. After a good 10 seconds, he shook his head.

"I'm sorry, I don't. You sure you okay?"

Not sure of what was happening; Ben turned and started walking in the opposite direction. He heard the man calling for him, but he ignored him.

Okay. He was on earth. Judging by the accent, he was in America. In a city which he didn't know existed and where people didn't recognize him. Had he somehow time travelled to past? Running to the nearest magazine store, he grabbed a newspaper. 15th August 2011. Nope. No time travel. That's when the headline caught his eye.

JUSTICE LEAGUE PREVAILS; ENDS THANGARIAN DICTATORSHIP

Reading the article, Ben found out about a superhero organization called The Justice League. Apparently, they had just thrown out some alien invaders.

Ben frowned. There wasn't any Justice League as far as he knew. And there hadn't been an alien invasion recently for sure. That could only mean one thing. He was not on earth. Not on his earth at least.

"Oh, boy."

He was in an alternate dimension.

Ben sighed. Well, not like this was the first time he's been in a parallel dimension. He had to find a way to get back. Things were not looking too good back home. Aggregor was rising. Plumbers were corrupted. Kevin was in no shape to take the role of a leader. Age had finally taken its toll on his Grandpa. Yep, he needed to get back home. And the best way to get back home was to find the Knight. He knew it could take some days.

But first, he needed to find out some info on this so called Justice League.

Finding a library was harder than he thought. He thought of transforming into XLR8 once but quickly rejected the idea. Here people had no idea who he was, and he wanted to keep it that way. After all, Gwen would probably have been alive if his identity was not public. He forced those thoughts out of his mind. He needed to focus.

Grabbing a seat in the café, he opened the search page. Seeing the familiar logo of Google brought a smile to his face. This place was not too different after all. Typing "Justice League" in the search box, he hit the search button. He was surprised to see so many results. Apparently they were very famous. There were three web sites claiming to be official JL website. Ben clicked the first one.

After almost 2 hours, Ben was walking out with a bundle of print outs. Luckily he had good cash on him. More luckily, this version of America used dollars too. Finding a decent hotel, he rented a room. Getting inside the room, he stared reading.

Justice League was a super hero organization created by 7 superheroes. They didn't have an official leader, but everybody thought Superman was the one.

Superman, an alien with immense power. From what Ben could gather, he was extremely strong. Strong enough to hurl a tank in the orbit. Almost invulnerable, capable of flight and lasers. Talk about being overpowered. Ben looked at omnitrix and smirked.

"Overpowered. Yeah, right."

Next was Batman, who some people thought was the leader of the team. Ben was surprised because he seemed to be only human in the team, Hence, least threatening. But he knew never to judge someone by what they seem to be. If so many people thought he was the one leading a team with that Superman guy in, he was dangerous. He operated in some island city Gotham and was known as World's greatest detective. And he dressed as a bat. Well, at least he was creative unlike that Superman guy.

Other members were Wonder Woman (seriously?)- Almost Superman. Flash- Fastest Man Alive. Green Lantern. Now that caught his attention. He was human as well but was given a device which many people thought was "universe's most powerful device." Being the holder of the omnitrix, Ben didn't agree with that. Not until he can see what that ring can do in person. Martian Manhunter was another alien and was from Mars. And he was green. Ben almost laughed. In his world, there weren't any Martians. His most prominent power was telepathy.

The last member was Hawk Girl. Though she was an ex member of the team. She betrayed the league giving her people info about them so they can invade. That sounded cold.

Ben looked at the clock. 4:12 PM. He was surprised how much time he's been here. He was feeling hungry. Getting out of the hotel Ben found a restaurant and was to enter it when he heard the explosion.

Author Note

I know it's slow and there was little action in it, but this is just the beginning. What happened to Gwen will be revealed in later chapters. And no, we've not seen last of Aggregor. PM me if you want to know something about story.

League will be in next chapter, I promise. At least Ben got to meet Superman. Technically. Like you saw, this isn't much similar to sandman's version. But I won't deny he inspired me.

There will be at least one more update this month. After that my college starts, but I'll try my best.

Anyways, please do review. I probably won't continue if not many people are interested in this story. Constructive criticism is welcome, but please no flame. And feel free to point out grammatical mistakes in your review.
