Star Trek/Ben 10 crossover

Chapter One

Captain Kathryn Janeway stood up from where she had been knocked down when the inertia dampeners had gone off line for a few seconds. Her ship Voyager had been on it's way home when it has struck upon the middle of some kind of spacial rift, which had caused the shields to loose some power and the ships haul to be stressed. Now they were some where else and she needed information.

"Tom, do you have our coordinates? Mr. Kim, how are the voyager's system. Tuvok, what how are the shields and weapons? I don't want to be completely helpless unless I know what is happening here." commanded the Captain as she looked for the information she needed.

"We appear to be... home. We're about a few kilometers from Pluto, or what is left of it. Seems like it's been destoryed by some kind of weapon. But there's trace of Starfleet anywhere. Seems like we've traveled back in time again." answered Lieutenant Tom Paris as he revealed where they were.

"There's some stress on our power supply as well as our hull, but most of that can be repaired in a few hours according to B'Elanna."answered Ensign Harry Kim as he took his post, refering to Lieutenant B'Elanna Torres.

"Shields have some decreases in power but can be repaired rapidly, weapons are functional and online." commanded Lieutenant Tuvok, head of security and tactical on the ship and therefore in charge of the firepower and protection of the ship.

'We're not sitting ducks, but not at full strength. If we're at Earth without Starfleet, the likely answer is time travel. Again. This is going to have me a headache... again.' thought Janeway as she figured out here next move.

"Harry, I need you to scan Earth and see what time period we have wondered into." asked the Captain as she awaited the results.

"Seems to be twenty-first Earth, but the weird thing is there are a number of technological devices on earth which are more advance then it should be for the timeline. As well as a number of unknown alien lifeforms and... human/alien hybrids. Plus unknown energy signatures. From broadcasts on the planet as well as the 'internet', the people on the planet have experienced alien life.

Captain, I don't think we have time traveled. If these scans are right, I think we're in another universe, at least. Assuming we didn't time travel into the past of another universe." answered Ensign Kim as he finished his analysis.

"If we did travel into the past of a parallel universe, it would be a first for Starfleet." commented Commander Chakotay, the second in command for the ship.

"Not exactly sure if this is something I wanted to brag about in my career." she started as there was a beep going off in the bridge.

"We're being hailed." said Tom as he picked up the communication.

The screen before them, once holding a picture of the space by Pluto, was replaced by the image of an older man who looked like he was in a some kind of run down vehicle. He had silver hair and green eyes, wearing a loud hawaiian shirt. He looked surprise to see them.

"I'm Magister Max Tennyson of the Plumbers. Earth is a level two technological society and therefore off limits for most space travellers, which begs the question of why there's a ship full of humans on the outer reaches of the solar system. I'm guessing there's a real doozy of a store involved with this." asked the man who seemed to have access with more advance technology.

"I'm Captain Kathryn Janeway of the starship Voyager. I'm guessing you're not a expert in water systems." she replied hoping to get more information from his first.

"The Plumbers is a intergalactic police force, form to help enforce the law and protect a number of inhabited worlds. Now that I've answered your question, maybe you can answer mine on what it is you're doing here? Especially since the human race is not ready to enter the intergalactic community for decades at least." answered Max, getting to the point.

"I know this is going to be hard to explain, but we are from the future of another universe." started Janeway, before she was stopped.

"Okay, time travel and parallel universes. Done that, got the t-shirts in my dresser. So do you need help getting back, or are you looking for a place for a colony. Because while I can let you settle on Earth, I can see if we can help you find a planet or build a planet if you need one." asked the older man as he looked at them.

Kathryn was shocked enough to stop, as building a new planet rather then terraforming it was impossible by Federation standards. He crew reacted similarly, "We are looking for a way home, but I am curious about what you mean by building a planet. You mean terraforming it, correct?"

"The Galvins have the technology to build a planet, they recently rebuilt their homeworld after it was blown into astroids in the Highbreed wars. They might be able to build you something to get you home. I am going to need to meet with you face to face to get up to speed on the situation. Do you use teleportation devices or shuttlecrafts?" asked the Magister as he was performing his job.

"We have teleporters, but we have to get closer to the planet. We can transverse the distance quickly, but we are afraid of discovery by Earth's governments..."

"Captain, don't worry. The Plumbers have an agreement with the nations of Earth, so you have nothing to worry about as long as you don't reveal you're human. The last part might freak them out a bit. I should give you notice I will be arriving with my grandson and his team. They a little young but experienced plumbers, so there might be a little social shock at them arriving on your ship. Can your transporter long onto my signal if I transfer it to my badge?"

"If it's a similar wavelength to this signal, then yes. Give us an hour and we should be in range." said Janeway as she ended the communication.

"Looks like we have guess to get ready for. I wonder how old he is if he's bring his grandson. He doesn't look that old, a little overweight but not old enough to have an adult grandson." asked the Captain before they prepared for the meeting.

'Max was right, I am a little shocked at this and so are my people.' thought Janeway as Max transported aboard with three teenagers.

One was a young man with brown hair and green eyes like Max's in a green jacket, black shirt, jeans and running shoes. On his arm was some kind of device or watch. Next to him was a ready headed young woman with the same green eyes as the other members of her family from Janeway's guess. Dressed in a red sweater, white dress shirt, grey skirt, black tights and black shoes. Next to her was the only member without a family resemblence. Black T-shirt over a grey shirt, jeans and boots. He was well muscle and his eyes darted around the ship as he looked it over, appraising it from the looks of it.

"The young man in green is my grandson Ben, his cousin and my only granddaughter Gwen and their friend Kevin Levin." answered Max as the commander who had gathered there had to hide the slight hints of a smile at the fact all of their names rhymed.

It was then the device on Ben's wrist began to turn yellow and flash as it spoke, "Large quanities of unknown alien DNA found. Preparing for massive scan in three... two... one."

The whole world seemed to turn yellow as light overwhelmed them, as Max said, "Don't shoot. We can explain. Shoulda known this would have happened."

The room dimmed and she could see security lead by Tuvok had their phasers armed and aimed at the Plumbers. Max had his arms in the air, Ben had his hands on his watch, Gwen's hands were glowing and Kevin... now looked like he was covered by the metal of the floor. Certainly not something human in the last two cases.

"Kevin is half-Osmosian, Gwen is part Anodyte... an energy being and Ben...

Ben is the wielder of the Omni Matrix, or Omnitrix. The most powerful piece of technology known to the universe. Baring beings who live in higher dimensions. It is a device which allows the user to physically change his DNA to any alien lifeform within it's database... and has a tendancy to scan any unknown alien DNA it comes across. Given the aliens in our universe have ability which humans and aliens would be considered superpowers, it is also considered one of the most powerful weapons in the universe." explained Max, trying to defuse the situation.
