Aliens Assemble

Chapter One

"So let's get me this straight. We're heading out into the Middle of Nowhere USA to find some kind of advance power source. Which either means alien or Hydra, why?" asked Hawkeye as the full company of Avengers were heading o this spot in the middle of the midwest.

"Because most of the advance energy sources are monitor by different groups, but especially groups like S.H.I.E.L.D. or people like me. So any kind of energy source we don't know about is usually aliens or some kind of supervillain, usually HYDRA related. Usually, which is why we're doing the big exam of the area." said Iron Man, as he flew in his power armor next to the quinjet as he spoke over the radio.

"Which is why we're here... in Nebraska, in a place which looks like a cattle feed field. With a crater. Okay, this looks more important then I thought." answered the archer as he looked at the field, which had a dent in the centre of the place. Which is where they landed as close as possible to.

"JARVIS can you do a scan of the area. See what happened here." the billionaire in the armor asked his computer manservant.

"The field seems to have elements of energy, which is vibrating at a different quantum frequency. It suggests extra-dimensional incusion. I am also detecting elements of unknown genetic material in the crater. Which could hint at an ultra-terrestrial being, but somehow the genetic material vanishes close to the hole. All that remains is some traces of human DNA." answered he machine before adding one little twist, "One of the human samples seem to begin where the alien DNA ends."

"So some kind of alien shapeshifter who can take on human form? One which would make infiltration much easier for an invading force." said the Black Widow as the female spy was looking at he potential threat assessment.

"Unless it's an extra-dimensional human who can become an alien, and he transformed back." said Falcon, poining out another outcome from the data. Many of his other Avengers looked at him like he was being nutty, he answered them back, "It's not likely, but still possible with that data we have."

"Yeah, but let's look at the more obvious one. Where we have a potential alien invasion from another universe. So we have an idea where this shapeshifter went?" asked Tony as he looked at the field as he computers traced down the path of the human elements.

"Looks like they was wandering around this field looking for something, then headed off towards what signs of civilization they could find. Which seems to be a road." said Natasha, the Black Widow, using the skills she had trained as a spy and assassin to track their subject.

"From the GPS and online maps, the closest place of civilization on the road is a truck stop dinner. Not to far from here. If we get moving, we might be able to reach it. The other direction has miles before it hits a town. If he heads there, we can get the police there to keep and eye out for us while we check the dinner." said Falcon as he used his own power armor to plot their course.

"So we have a plan. Let's get to it so we can see what this thing really is." continued the man in purple with his quiver of arrows. Which is when the Avengers moved out.

At that time, in a dinner stop...

Ben was glad his money was good where ever it was he had ended up. Which seemed to be a place in the rural American, which might explain why his money had been taken. He was glad as he enjoyed his chili fries and milk shake, which he might not have had otherwise. He was trying to figure out where he was, given he believed he was not in his home universe.

'Given the fact even in the trailer parks, like the one Jennifer Nocturne's mother lives in, knew who and what I am... Entering this dinner would have had at least one person to comment on The Ben Tennyson being here. Instead, nada nothing zilch. Like it was in Rex's universe. So what kind of universe am I in, that's the question?' he thought to himself as he waited for anything on the new which could help him. There had been a little to given him clues as to what kind of universe this was.

'An awesome one, since it seems to be filled with superheroes. Course, the downside is there is supervillains as well. It seems like this S.H.I.E.L.D. group is kinda like a mix of the FBI, the CIA and the Plumbers. Responsibile for the superhuman population. Which means they will likely be looking for me. Either them or one of the hero teams like the Avengers.' Ben debated what was going to happen. He hoped it would be peaceful and uneventful...

'But all of the comics I have read always has a hero showdown where they good guys kick each others butts before they discover they're on the same side. Which might be just fiction. Except for the fact the same thing kinda happened when Rex and me met. So got to get ready for a knuckle-bruising fight if and when it comes. For now, chili fries and shakes till that happens. The question is how long before someone discovers where I am.' he continued to work on what was going to happen as he ate the last of his fries, soaking up the chili which had been on them.

It was then the door jingled with it's little chime, and the unusual customers entered the stop as the people in the dinner stopped what they were doing. The Avengers had come in to the little restaurant and store. Ben thinking to himself, 'Not that long it seems. Now what happens?'

He waited for the heroes to get past the admiration of the workers and the others, as the group spokesman in most things known as Iron Man or Tony Stark said, "We were in the neighbourhood and the Hulk wanted a good piece of pie. So we decided, why not? So what's new with all of you?"

Ben noticed Iron Man was taking a deep look at him. Which given the brain the man had could be compared to a Grey Matter or Brainstorm with the tech skills of Upgrade and Jury Rigg, meant the hero was likely scanning Ben to discover the alien shapeshifter's origins. Likely from the nasty crater which Ben had left when he landed from where he had entered this world.

'Likely an energy sensor or something, even if it can't detect the Omnitrix it could detect the energy to get here from home. Then a DNA scanner to see where my trail went. Likely based on where I could find what I need, food for example. So what are you Avengers plan on doing?'

In the same dinner...

Iron Man had been scanning the dinner for the human DNA which had had found on site, and was finding it in a young dark haired man in brown pants with a green and black shirt. Finishing a plate of chili fries and a milkshakes. He then made some less then obvious signals which would point out who it was in the building who had landed in the cattle field.

Tasha was the first to notice and keep a hidden eye on the young kid, either in his late teens or just leaving them. Assume he was a human being. Not sure why he would take the form of a kid, but if he was an alien invader he had to have some reason. The other Avengers followed depending on their skills in keeping observations secret. Which Caps, Falcon and even Hawkeye were skilled in. They tried to avoid having Thor and Hulk watch the mark, given subtle was not a skilled they perfected. They were better at attracting attention so no one noticed the others.

'Much like I am. Outside my stealth armor.' thought Tony as he figure out the alien's angle.
