Ben 10 vs The Avengers

Part 1

Chapter 1 – Cross Dimensions

The year was 2019. The world that Ben once new was all, but gone. After the last major alien invasion in 2018 the governments of the world finally had enough. They banned all aliens from the Earth and established the AATF, Anti-Alien Task Force. Large space cruisers form a blockade around the earth, keeping any and all unwelcomed guests from entering the planets orbit.

For Ben, this meant that he was no longer a hero. In fact, he was a wanted criminal. Having over a thousand aliens in the ultimatrix, He was violating Earths laws against alien intruders. For several years Ben, Gwen, and Kevin have been moving from hideout to hideout, trying to keep out of the AATF's watchful eyes. It is now the year 2029. This is the year that everything changed. This is the year that Ben 10, left our dimension…

Ben sat on the grassy hilltop looking over a vast forest of bright green trees. He was currently in the back country of England. His team's latest hideout was an old WWII bunker hidden within the denseness of the woods. The small hill Ben sat upon was only a few feet away from the bunker's entrance, which was hidden within the thicket. His mind was a blur as he gazed out at the horizon.

"Today is the day." He thought. What was left of the Plumbers on Earth were dedicating their lives to helping Ben end the AAFT once and for all. They had tried so many different plans and lost so many good men and women in the process. This was their last chance, though. The final plan to end the AAFT. The Plumbers had been gathering what little alien tech that was left on Earth up and bringing it to the bunker.

There they used it to build a sort of make shift portal. This portal would allow Ben, Gwen, and Kevin to go back in time and stop the AAFT from ever happening.

"Ben its time." Someone said behind him

Ben turned to see his cousin, Gwen, standing behind him. Ben sighed and stood up.

"Then we better not keep them waiting." Ben responded.

They both walked down the hill towards the bunker. The sun fell under the horizon as they did and the sky became dimmer. Once inside the bunker they walked down a long spiral staircase that took them five floors down. On the bottom level was a large room that contained many wires and a large ring-like machine in the middle. Five or six of the Plumbers were there adding the finishing touches to the portal. Kevin stood before the machine and turned towards Ben and Gwen as they walked in.

"You two ready?" he asked.

"I think so." Gwen responded.

"You sure this things going to work?" Ben asked.

"Not even in the slightest, but it's the only chance we got." Kevin said.

"Alright everyone let's get this show on the road!" Kevin yelled to the Plumbers.

They all got into their positions and readied the portal. Kevin, Ben, and Gwen stood before the large ring. Kevin then nodded to one of the Plumbers behind a control consol. The Plumber flipped a few switches and pressed a large button in the center of the consol. The ring shook for a moment and then let loose a few sparks. Suddenly a bright, swirling, vortex appeared within the ring. It glowed a bright blue and seemed to fade in and out of existence.

"The portals not stable! No telling how long it'll stay open. If we're going to do this we got to do it now!" Kevin yelled over the hum of the machine. Gwen looked over at Ben. He gave her a nod, telling her that he was ready. As all three of them gazed into the vortex they made the decision. All three of them stepped into the vortex and immediately vanished. The portal then let out two burst of sparks and suddenly caught fire. The vortex faded out of existence and the loud hum stopped abruptly.

Ben saw flashes of different colors and strange shapes he couldn't explain. His brain began to hurt as he traveled through the vortex. He had to close his eyes to make the pain in his head stop. Without warning he hit something hard. It knocked the wind out of him and forced him to grasp his stomach. When he opened his eyes he realized it was the ground. It had worked, he had traveled through time. Ben stood up slowly and looked around at his surroundings. He was in an alleyway. He could hear car horns and there people walking up and down the sidewalk at the other end of the alley. He slowly exited the alleyway and began to better recognize his surroundings. He was in New York City.

"Where are Kevin and Gwen?" Ben wondered.

He looked back down the alleyway, but saw no sign of them. That's when he noticed and nearby newspaper stand. Ben rushed over to see if his eyes were just playing tricks on him. He picked up one of the papers and felt his heart stop. The date on the paper was the same date from when they left. Ben set the paper down and backup against a wall.

"It's over. The portal didn't work. It just teleported us instead of sending us through time. Who knows where Kevin and Gwen are. Probably already in the hands of the AAFT." Ben thought. That's when Ben realized, no one noticed him. Ben was the most wanted criminal in the world and yet no one on the street batted an eye at him. Ben walked back up to the newspaper stand and said to the man behind the wood desk,

"Excuse me sir, but do you know who I am?"

"Never seen you before in my life, now are you gonna buy a paper?"

Ben backed away from the stand and began to make his way down the street.

"This doesn't make any sense. I didn't travel through time, but I'm clearly not in the same place I was when I left because nobody knows me." Ben thought.

That's when a large crash broke his train of thought. People began to run in the opposite direction, away from the danger. Ben looked up to see flames spewing out of the top floor of a building call the Daily Bugle.

"That's weird. I've been to New York a thousand times and I've never seen that building before." Ben thought.

"Never mind that Tennyson, there are people in trouble up there and if nobody here knows who I am then I guess they won't care if I go hero!" Ben said to himself.

He touched the dial on the Ultimatrix and it popped up allowing him to select one of his many alien transformations.

"I've got just the guy to help put out those flames." Ben said with a smile.

He slapped his hand down on the dial and a bright, green, light surrounded him. When it vanished, Ben was gone. In his place was a flaming alien with molten rock for skin.

"What?! Heatblast! I didn't pick him. I needed Big Chill! What's going on with this thing?" Heatblast wondered.

His train of thought was disrupted again by the screams coming from the burning building.

"Damn! This we'll have to do." He said.

Fire than erupted from his hands and Heatblast shot up towards the building.
