(A/N: Well I haven't had much time to write in awhile so I did some bits here and there. Suddenly I realized I actually had a whole story written. And since my summers free I decided now would be a good time to start posting it. I'll post a new chapter every three days, provided nothing happens like a dead laptop. So enjoy and review. Hope I haven't forgotten anything.)

Natural Disaster

Chapter One: The Underground Movie

Ben lay on his buck in the Rust Bucket watching clouds pass by the window. It was late in the afternoon and he was almost board enough to go see what his cousin Gwen was doing, almost. They had spent the last three days driving through an endless desert with an air conditioner that kicked on and died sporadically. He looked at the thermostat; it had broken half way through the nineties.

He started fiddling with the Omnitrix playing to go Grey Matter and super charge the air conditioner when the then Rust Bucket shook with a muffled explosion. Ben jumped to his feet ready to go alien and finally see some action. Instead he found Gwen standing in front of the microwave covered in an unidentifiable food.

He doubled over laughing. "That's a good look for you Gwen; you should have the microwave throw up on you more often!"

"Move it dweeb." She shoved past him grabbing some clothes and went to shower.

Their grandfather sighed in frustration "Ben I wish you two could get along. How would you feel if that had been you?"

"But it wasn't me so no problem." Ben said setting at the table.

"Sooner or later you're going to realize that teasing her like that isn't a good idea."

"Come on it was just some harmless fun" He reached over and grabbed Gwen's laptop. She thought it was safe because she had a thumb print scanner on it but Ben had found a way around that in a day. He pulled out a piece of tape with her thumb print on it and a few seconds later was surfing the net.

It didn't take him long to find a leaked trailer for the Sumo Slammers movie. His grin grew as he found out that there were underground showings of a stolen copy. And one was just a few miles from their current route.

Now how to convince their grandpa to stop at the next city. His answer was provided when the Rust Bucket's engine sputtered and almost died. It was always falling apart; one more time wouldn't be suspicious.

Ben went back into his and Gwen's room closing the curtain that separated it from the rest of the RV. He turned the dial on his watch selecting Grey Matter, and hit it. Surprisingly he actually got what he wanted. The five inch tall alien peeked through the curtain to make sure his grandpa hadn't noticed. The older man hadn't, busy tapping out the rhythm to some horrible song on the radio.

"Good, now where to get in?" Grey Matter moved along the base of the cabinets until he came to an outlet. It only took him a second to remove the screw holding the cover on and squeeze into the bowls of the Rust Bucket.

He worked his way along the wires and hoses until he found what he was looking for. Grey Matter started loosening pieces part way then watched to make sure the natural vibration of the RV would finish the job in a few more miles.

"Perfect!" he climbed back along the wires heading straight to his room this time. Just as he got out of the wall a beeping along with red light told him his time was up.

Ben crouched on the floor smiling, until he opened his eyes and saw Gwen on her bunk watching him over the top of her book. "What are you up to?"

"Uh, nothing. I'm not up to anything" Ben said trying to think of a better excuse.

"Sure you aren't." Instead of pressing the subject though Gwen continued studying from her science book.

Ben watched her cautiously, it wasn't like her to let things go. Then again what kind of kid studied over summer? He didn't have much time to worry about it as the desert had given way to lush suburbs. He watched the homes pass by while waiting for his handy work to kick in.

The Rust Bucket shook and died, Ben smiled, right on time. Grandpa Max pulled them RV to the curb and climbed out to check the engine. Several minutes later he came back in shaking his head. "Well I can't see anything wrong. Looks like we'll be here awhile."

So far so good Ben thought, now for the tricky part. "So grandpa, if we're going to be stuck here for awhile can I go to this store downtown with the limited addition Sumo Slammer game?"

"Ben, I can't just let you go wondering around by yourself."

"Why not? I have the Omnitrix incase anything happens, and I promise not to use it unless I have to. Come one we've been stuck in the Rust Bucket for three days. I promise to be good, please?" he gave his grandpa his best innocent pleading smile.

"I don't know." He said.

"What if I went with Ben?" Gwen said stepping out of their room. "I'll keep him out of trouble."

"Hm I guess it'd be alright. But you two be careful and don't stay out late."

"We won't." Ben said shoving Gwen out the door before their grandpa could change his mind. He grabbed Gwen's hand and ran down the street.

Once they were a block from the RV Ben stopped. "Thanks Gwen, see you later."

"Hold on I'm coming too." Gwen said.

"What? No way. You're not coming."

"Oh? Then I suppose you want me to tell grandpa what you did to the Rust Bucket?"

"What? I didn't do anything. That piece of junks always breaking down."

"Right, and I'm supposed to believe that you just happened to be Grey Matter and the Rust Bucket just happened to break down a few minutes later?" Gwen asked, hands on her hips.

"Fine, what do you want to keep quiet?"

"Two things. One I'm coming with you."

"Why?" Ben asked. Gwen never wanted to willingly spend time with him.

"Because I've been stuck in the rust bucket just as long as you and the Sumo Slammer movie is better than spending the night with grandpa." Gwen said grinning.

"Don't be silly Gwen, that's not out yet." He said giving a nervous laugh.

"Oh really? I thought you were going to that secret showing of it."

"How'd you know about that?"

"I checked my browsing history; you never bother to erase it after you use my laptop. So I've seen everything you've done when you took it."

Ben gulped, "everything?"

"everything." She confirmed.

That was a lot of black mail material she had on him then. "So what do you want to keep quiet?"

"First off I'm coming with you. Better than sitting in the Rust Bucket all night."

"And the second thing?" he asked hesitantly.

"After the movie you buy me a pizza."

"That's it?"

"That's it." Gwen said.

Ben thought about it. Really it was a better deal then she normally gave him. And not to bad considering he'd agree to be her slave for a week to see the Sumo Slammer movie. "Alright deal."

He led them down street after street. The homes turned into apartments and the buildings grew. Finally they were in a back alley, trashed clogged the gutters. Cracked lights were flicking on as night fell. They stopped in front of a ruined brick building.

"Ben, are you sure this is the right place?" Gwen asked glancing at the dirty cracked windows

"Yea, quiet being a baby."

"What did you call me?"

"shh." Ben went in and Gwen followed keeping a wary eye on their surroundings. It was the perfect place for an ambush.

Bare bulbs illuminated a dank hallway, there was quite a bit of fire and smoke damage on the walls. "I swear Ben, if we get attack by aliens I'll get you."

"Relax, were here." He opened a heavy door and Gwen gasped. They were in an empty factor, giant Sumo Slammer banners hung from the ceiling to floor. Movie screens showed the Sumo Slammer trailer and a mass of people crowded around the center of the floor dancing.

A DJ stood on a raised platform spinning neo colored records. The crowd was a little intimidating, ripped t-shirts, black and silver jewelry and spiked green Mohawks. Everyone seemed to be having fun though and Gwen started to enjoy it moving along the edge with Ben.

The pulsing beating music died down and the DJ leaned over the mic. "hey hey all, this is DJ Spinner. In just a few we gonna start the sumo slam down! So get ready to hit the floor!"

The music started again and the crowd surged around them. Suddenly a girl detached herself from the mass and ran towards Ben and Gwen. "Oh my god Gwen is that you?"

"Jen?" Gwen asked shocked.

"I can't believe it's you Gwen! It's been forever!"

Ben looked between the girls. The new one had black hair with two colored highlights in front. He also noticed Gwen's reaction, after fighting aliens together he'd learned to read her body langue. When she saw the other girl she'd tensed.

"So Gweny, whose this? Your boyfriend?" Jen asked.

"Ew no, this is my cousin Ben."

"Shame, he's kind of cute. Well I hope to see you after the movie." She grabbed Gwen in a bear hug. Ben noticed Gwen looked ready to bolt and didn't return the gesture.

When she left Ben gave Gwen a quizzical look. "Ok who was that and what just happened?"

"That was Jen, she's an, old friend."

"Really? You didn't seem to excited to see her."

"What do you mean?"

"Come on Gwen, I know you well enough to see how tense you were."

"It's, complicated." She said looking away. Before Ben could try and get anything else out of her the lights dimmed and the music stopped.

"Alright everyone, I spun the disks now it's time to bring the show. Settle in and enjoy!" all the screens went black, a moment later the Sumo Slammer movie started. Ben grabbed Gwen's hand and pulled her to a less crowded area.

The first few minutes played, then the screens went black again and the lights snapped on. The main doors burst open and a fully armed S.W.A.T team ran in. "No one move! You are all under arrest!"

(hm should I end it here? No I have a much eviler spot to do so)

For a heartbeat no one moved, then they screamed and ran. The crowd moved in every direction trying to escape the police. They slammed into Ben and Gwen forcing them apart, elbows and feet stabbed them. Before Gwen had time to react someone hit her from behind and she fell forward.

Ben fought against the mass of bodies to where he had last seen Gwen. For a few panicked moments he couldn't find her. Then he saw her back, just as some slammed into her. He watched as she pitched forward, he knew if she hit the ground she'd be trampled.

He shoved someone out of the way and grabbed her arm pulling her to his chest. Ben did his best to shield her from the mob, an elbow slammed into the side of his head. He staggered but refused to let go of Gwen.

They we being pushed along with the crowd now. Ben tried to steer them out of the panicked mass but the police were wading into the crowd now, weapons drawn sending everyone into a frenzy.

Ben and Gwen were shoved from all sides; someone's leg shot out and tripped them. As they fell Ben twisted to that Gwen was under him in the hopes of being able to protect her from the stampeding mass.

He braced himself for the crushing blows, but there were none. He could still hear the panic though; DJ Spinner was shouting something trying to control the mob. Ben lifted his head and looked around. They had been pushed into a shallow alcove along the wall. A painting tarp hung against the wall, the rioting teens had over looked it completely.

Ben sat up realizing he was still holding Gwen to his chest, he hastily let go of her. "Sorry. You alright?"

"Yea, thanks." She looked out at the confused mess of people, they were just running in circles now. Police were coming through the other exists. Some of the teens chose to try and fight and were actually managing to hold their own because the officers weren't using their guns yet, just riot sticks.

"Great Ben, I'm going to get arrested because of you!"

The painting tarp shifted and Jen stuck her head out. "That won't do, come on they missed this way."

She grabbed Bens hand and yanked him through, Gwen hesitated a moment but Ben reached back and took her hand.

Jen pulled Ben down a corridor that had been freshly painted, through a side door and down a set of stairs. Finally Ben pulled his hand free from hers. "Thanks for the save but where are we going?"

"The police have the streets covered, so we'll go under them." Jen said picking the lock on a door.

"So we have to go through the sewers?" Gwen asked.

"No, the cities drainage system. Its dry right now so it's just and bunch of cement boxes."

They followed her to a maintenance room and down a ladder into the drainage system. There was no light in the tunnel and Gwen felt Ben put his hand on her should so they wouldn't be separated. Jen pulled out a pin light, it wasn't enough to really see by but they followed it since she seemed to know the way.

A few hundred feet into the tunnel something stirred in the shadows. A homeless person suddenly appeared reaching for Gwen. "Pretty!"

Before Ben could act Gwen brought her foot down on the hobos head sending her staggering away. They started moving fast incase the homeless man had friends. Ben smiled in the dark, how many girls did he know who could do that. "Good job. Gwen Tennyson, Hobo thrasher."

Not long after that they heard running farther down the tunnel and two strong lights nearly blinded them. "Police! Don't move!"

"Shit." Jen broke into a run, Ben and Gwen followed. With the light from the officers illuminating the tunnel Ben let go of Gwen so they could move faster. The tunnel floor was cracked now jutting up in spots. One of Gwen's feet hit a raised spot wrong and she tumbled to the ground. The police were on her in seconds, the end of their guns in her face. "Stay down!"

Ben saw Gwen fall and turned to help her. Seeing the officers hovering over Gwen, guns drawn and trained on her. Something snapped in him then.

Ben hit the Omnitrix and jumped. Diamondhead landed between the police officers and Gwen. His hand shot out and grabbed one of the officers guns crushing it. "Don't ever point a weapon and her!"

The second officer grabbed his taser and fired at Diamondhead, the prongs bounced off him. The officers backed up unsure how to proceed. Ben didn't wait for them to decide; he spun around and scooped Gwen up in his arms running down the tunnel.

They caught up with Jen in moments, but the officers were following them again. Gwen leaned to the side in Bens arms and held out a hand. "Camafelt Vaporis!"

A wall of steam filled the tunnel hiding them from the police officers and covering their escape.

After a few more turns they came to the end of the drainage system. Twenty feet up in a dried river basin. Across from them was another pipe and the only place they could hide. Diamondhead set Gwen down and laid a hand flat on the cement. Crystal shot across the gap forming a bridge.

"Hang on ladies." He said grabbing one under each arm and running across the bridge.

On the other side he set them down and slammed a fist into the bridge shattering it. At the end of the tunnel the two officers watched them. With a beep Ben changed back into himself and gave the officers a cocky wave.

As he turned to follow Gwen and Jen a gun shot rang out in the open space, Ben spun once and collapsed to the ground.

(A/N: Ah yes that's a nice spot to stop it. See you all on Friday.)
