It had been roughly 7 years since Ben Tennyson put on the omnitrix for the first time.

3 years since Kevin joined his team and helped stop the highbreed invasion.

30 months since he got the ultimatrix from Albedo.

2 years since he had gotten the final Omnitrix and started saving the galaxy on a weekly basis with his partner, Rook blonko.

And it had been 10 months since he defeated Maltruent, saved the entire universe, and decided to go on a universal roadtrip with Rook, Gwen, and Kevin, which ended 2 months ago.

After seeing the best and worst of the entire universe, Ben Tennyson was

"...So BORED!"

"Agreed. After all that we have seen and been through in our intergalactic endeavors, everything is now seeming, for lack of a better word, super lame."

Ben and Rook were having a break. Bellwood was a quiet place now. Aliens walked the streets along with humans, the Plumbers were keeping the peace, and most of Ben's enemies were either in hiding or behind bars.

"There's litteraly nothing interesting going on!" Ben took a sip of his smothie "I actually envy the No-watch me. He dosent have to be as bored as me because there's still stuff he hasn't done yet!"

This gave Rook an idea. "Perhaps we could pay some of the alternate universe Bens a visit."

Ben's eyes suddenly lit up. "Rook, that idea just gave me an idea! Professor Paradox says that the multiverse is like a giant tree, right?"

"And the Contemelia plant the seeds, yes. Ben, where are you going with this?"

"If the multiverse is a tree, the the omniverse must be an entire forest!"

A portal opened up next to the duo as professional paradox walked out of it, holding a black suitcase in his right hand.

"Benjamin Kirby Tennyson, your ability to understand the vastness of reality truly never ceases to amaze me."

"Professor!" Rook stood up and shook the timewalker's metal hand "To what do we owe the pleasure? Is there some sort of omniversal dilemma in which you require our assistance?"

"Not at all, Rook. Actually, I came to help you. Ben is suggesting that rather than visiting universes similar to your own, the two of you, along with Gwen and Kevin occasionally, should take a few days off each month to visit other multiverses."

Ben looked a little worried. "Let me guess, we can't do it because of time and reality reasons."

"On the contrary Ben. I came here to give you the component that the Proto-truck needs to be capable of cross-dimensional travel. In this case is possibly one of the most versatile tools in the omiverse, made by a child whos' vast intellect and comprehension of the true purpose of technology rivals even that of Azmuth."

Rook shook his head in disbelief "Professor, I know that you are telling the truth. You are the last person that I expect to lie. But I find it hard to believe that a child is capable of making a device as complex as you make it out to be."

"Well you better believe that I made it."

From the portal, a small kid with glasses, a white bike helmet with a cyan gem in the front, and wearing a cyan and white business suit emerged. "My name is Benjamin Henry Garraventa. CEO and sole heir to Garaventa Corp. The biggest and most innovative technology company in the world! At least in mine. It is a huge honor to finally meet you, Ben Ten. Hero-to-hero, I know what it's like to see the big picture, only to go back to normality. Things get a little, well, boring. But that's about to change!"

Ben and rook were speechless. "how did you-"

"Right. 1) call me mastermind to prevent confusion. It's my not-so-secret identity. 2) I posses the gem of thought," Mastermind pointed to the gem on his helmet "It allows me to read minds, use telekinesis, communicate with anything on the psychic and technical level, and I have access to half of all the accumulated knowledge of everyone and every database on whatever planet I'm standing on! Don't worry, the half I have access to does not include any personal information."

Ben smirked "So if you were on Galvan Prime-"

Mastermind chuckled "Yeah, I made Azmuth look normal. Also, fun-fact, he had over thirty failed prototype omnitrixies, and he just let me have all of them! That is, after he took out the cores. I used them to make something for a friend, but that's a different story for another day. As for your third question you were about to ask; if the omniverse is a forest, I came from the oldest tree. Dimensional set 1, universe 1, timeline 1. AKA: dimension 1.1.1.. But enough about my universe, that's not the one that's under inter-dimensional level siege. Now, dimension 5.1.5, that's under some serious siege. Wanna go help 'em out?"

Again, Ben and Rook were silent. They looked at Paradox's briefcase, then at Mastermind, then at each other before nodding and said "Let's/Let us do this!"

Paradox opened the briefcase to show the partners a dozen small, thick disks roughly the size of dollar coins and an inch thick. "These are called 'upgrades'." Paradox explained "They are made up entirely of self-replicating nano-machines that are capable of improving the performance of any machine-"

"Or, in this case," Master mind continued as he took one of the upgrades out of the case "It can give machines additional features, such as inter-dimensional travel." he walked over to the proto-truck and stuck the upgrade onto the hood of the car. The upgrade seemingly melted into the truck and into the engine. "Just press the new button and the coordinates will already be put in. A portal will open, and you will need to fly through it."

Ben nodded "Got it" as he and Rook got into the Proto-truck.

Mastermind stopped them to tel them something. "I almost forgot! The computer also has data on the heroes and villains of that dimension! The villain's weakness is intense radiation!"

Ben gave a thumbs up as Rook activated the dimension jumper. A portal appeared in the sky as the proto-truck transformed and flew into the vortex.

Paradox looked at Mastermind and asked "What exactly is in dimension 5.1.5.?"

"Oh, just an alien species called life-fibers."
