Here we go! An all new fan fiction! This is the first fan-fic I have that contains a Disney XD original series. I hope that you all enjoy it, and if you do, leave a review to let me know what you think. Oh, one more thing, the events in this fan fiction occur before the season 2 finale of Lab Rats, and the season 1 finale of Gravity Falls. This also assumes that Mission Creek is in California. Anyway, without further ado, here's the first chapter of Ultra-Chip. Enjoy!:

One

Adam, Bree, Chase, and Leo entered the Davenport mansion. They had just gotten home from school.

Leo took off his backpack and tossed it on the couch. "Finally, the fun begins," he said. "After a long day of tests, it's time to start the weekend!"

Chase smiled at him. "Not just any weekend, the weekend where we take a road trip to Washington State. I've been waiting for this trip for such a long time."

"Yeah nothing beats riding a cramped rental RV for 12 hours with three dimwitted brothers, a father with an ego bigger than this world, and Tasha, who's not too bad" said Bree.

At that moment, the elevator doors opened and Donald Davenport entered the family room, followed by Tasha. Both of them were carrying suitcases.

"Alright guys, let's get this vaycay started!" said Tasha. "TGIF!"

Leo shook his head. "Mom, please don't ever do that again."

"Oh, come on," said Tasha. "I can be cool."

"Yeah, about as cool as a—" began a giggling Donald, but his wife shot him a withering glare. "I mean… uh…" Mr. Davenport's shoulders slumped. "I'm driving the whole way now, aren't I?"

Tasha nodded.

Donald sighed. "Oh well, either way, I need this vacation," he said. "I've been working on a special project that's been stressful."

Tasha gave her husband a look. "You didn't mention anything about a special project."

Excitement grew over Donald's face. "Okay, I wasn't gonna tell you guys about this just yet, but I'll announce it anyway."

Bree sighed. "Based on the look on your face, this is gonna be great," she said sarcastically.

"For the past two weeks, I've been working on constructing a new bionic chip," said Donald. "It would include all of Adam, Bree, and Chase's abilities, plus more that I never got to add to theirs. I plan to call it the Ultra-Chip."

Leo smiled. "Finally, it's about time you realized that it's time for me to be bionic."

Tasha shook her head. "That's not happening."

Donald nodded in agreement. "She's right. I've already been talking to a cousin of mine who is willing to have the chip surgically implanted inside of him once it's finished."

Leo sulked. "Now I'm not liking this as much."

Bree rolled her eyes. "You're telling me. This means that we'll have another guy on our team. And I've been saying for such a long time: we need more girls!"

"Wait, aren't you worried that your evil brother Douglass might find out about it and try to steal it?" asked Chase.

"It's very unlikely that that'll happen," replied Donald. "And even if Douglass somehow finds out about it, there's no way he can steal it since we have a state-of-the-art security system, Eddie."

"Again, aren't you worried that your evil brother Douglass might find out about it and try to steal it," repeated Chase.

"You worry too much," said Donald. "Besides, this could be a great opportunity! With the new member our team, we could do even bigger things, like protecting small countries from invasion. Then, they can honor me by naming a city after me, or putting my face on their flag!"

"Great, then I'll have a whole country full of kids I don't know that hate me," said Leo.

Mr. Davenport rolled his eyes. "Whatever, it's not like this'll be happening anytime soon. Anyway, I hope you guys packed your bags, because we'll be leaving in a couple of minutes."

Bree zipped up the stairs, filled a suitcase with clothes, and super sped back down to the living room. "Done," she said.

Chase, Leo, and Adam sighed as they jogged up the stairs.

The next morning around ten, Donald finished filling the gas tank and got back into the RV.

"That didn't take too long, right," said Donald as he started the vehicle.

"No, it didn't," admitted Chase, who had been sitting near the front. "But this was our thirtieth stop for gas in nine hours."

"Okay, so maybe this thing has horrible mileage, but at least we're almost there," said Donald.

"I hope you know that we're in Oregon," said Chase.

"I did not," said Donald as he pulled onto a dirt road. "But now I do."

Leo walked over to where Chase was and sat down. "This ride has been so long and there's nothing fun to do on this thing? Where are we anyway?"

Donald glanced at a road sign they were passing. "Some town called Gravity Falls."

"Wow, clever name," muttered Chase.

Suddenly, there was the sound of a small explosion in the engine.

Tasha yelped in surprise. "Donald! Pull over!"

Mr. Davenport quickly turned into the first parking lot they saw. After shutting off the engine, he got out of the vehicle to inspect the problem.

Adam and Bree approached Lee and Chase. "We're gonna go outside to get some fresh air and maybe look around in that tourist shop we parked in front of. You wanna come?"

Leo nodded. "I'm in."

Chase looked out the window and saw that they had parked in front of a place called the Mystery Shack. He wondered what kind of gimmicks they sold to try to rip people off. "Sure, why not?"

Well, what do you think? I know that no Gravity Falls characters appeared in this chapter, but I guarantee you that characters from Gravity Falls appear in chapter 2. But I hope you chapter one, and feel free to leave a review with your thoughts.
