"Ben 10 Omniverse Dimension in Undertown."

-Everything was as normal, the inhabitants were going about their daily lives and others doing their shopping for the day, everything was fine until out of nowhere an explosion originated in a warehouse of a package delivery company called Argistix Security-.

-From the explosion came out 2 subjects, one was a muscular gray alien of humanoid appearance. straight, long and white hair, with an axe in hand and on top of a glider and another robotic subject of purple color flying with a jet-pack, both carrying bags with a few packages and cash.

-A hedgehog/rat alien emerges from the destroyed warehouse along with two security robots.

"Focus only on the robots and forget the elderly Argit and the other characters in the background."

Argit: THIEVES!!!! *looks at his security robots* GUYS, CATCH THEM!

Security Robots: Yes Master Argit *turns their hands into energy cannons and shoots at the robbers*.

-In the midst of the gunfire, the long-haired gray guy known as Sunder spun his axe to form a shield to protect himself, his partner and the merchandise. subsequently, his robotic partner known as SevenSeven pulled pistols from his back and fired back, but with much more power at the guards destroying them in the process.

Argit: Oh no, my guards *worried*.

Sunder: Ha ha, well done SevenSeven.

SevenSeven: fdfkhjdkfhdkf

Argit: Someone catch them!!!! *shouts to the four winds for help*.

-Out of nowhere a blue sports car and an orange and cream colored ship appear with the intention of chasing the thieves.

Kevin: Don't worry Argit, we'll take care of it.

Rook: These evildoers won't get away with it.

-With Sunder and SevenSeven.

Sunder: *looks at the newly stolen merchandise* Ha ha, stealing these proton cannons with a little money was a good idea.

SevenSeven: hifoofkopffkpf

Sunder: Yeah I know, the plasma shields were missing, but we don't have enough room in the bag to steal it too, it'll be for next time.

-Suddenly some gunshots came out of nowhere with the intention of making the thieves fall.

Rook: *draws his microphone* In the name of Galactic Law, I order you to stop.

Sunder: Oh no, the little plumbers are here!

SevenSeven: ddgfjjdjknkjgkg

Sunder: Well remember what we planned, EVASIVE MANOEUVERS.

-Sunder and SevenSeven begin to pirouette in the air, Seven-Seven in turn begins to shoot at Kevin and Rook.

Kevin: Rook, I told you that wouldn't work *begins to accelerate*.

Rook: I had to try, didn't I? *also accelerates*

-Rook and Kevin along with Sunder and SevenSeven were in a very intense chase with many shots, but neither side could get the situation in their favor.

Kevin: This isn't coming to anything, I'm going to put an end to this *pushes a button on his car*.

-When he pressed the button he released some cannons where the headlights of the car were and these gave them intense shots that broke Sunder's glider causing it to fall and SevenSeven went to help his partner.

Kevin: On target *getting out of his car*.

-Kevin gets out of his car, absorbs his own car's matter and approaches the thieves.

Kevin: You guys are done for *turns one of his hands into a giant sledgehammer*.

SevenSeven: Glklkfhllklklñññ

Sunder: Don't worry, I'll be fine *he throws the bags he brings with him to SevenSeven*.

Sunder: Take them and run away, we both knew this would happen, go with the pig man, the lizard girl and the chicken man, I'll take care of stopping these plumbers.

-Immediately Rook arrives, catching up with Kevin.

Rook: I wouldn't be so sure *draws his Proto-Tool and points it at Sunder and SevenSeven*.

Sunder: *looks at SevenSeven* WHAT ARE YOU WAITING FOR? RUN AWAY!

-At that moment SevenSeven escapes flying, Rook gives him some shots to stop SevenSeven, but Sunder makes a shield with his axe protecting him again.

Sunder: I wouldn't do that if I were you Plumber, we have valuable loot that we have to protect, so I would suggest you lower your weapon

Kevin: I don't think so Sunder

Rook: You got here *points his gun at him*.

Sunder: Don't be so sure, plumbers *swing his axe and sets out to attack Kevin*.

-Sunder begins to hit Kevin with several hacks with the intention of hurting him, but since Kevin absorbed his own car, he was indestructible and would not take any damage.

Kevin: Come on Sunder, is that the best you can do, I remembered you more.... STRONG *that word he says simultaneously as he kicked him*.

-Sunder resisted Kevin's kick, he immediately got up to continue fighting, but Rook with his fighting techniques was able to take Sunder down and handcuff him-.

Kevin: Good job Rook *turns back to human of flesh and blood*.

Rook: Thanks, but SevenSeven ran away with the packages and the stolen money.

Kevin: That's right let's go *he heads to his car*.

-They both get into their vehicles and drive off after SevenSeven, but not before calling the plumbers to teleport Sunder to the plumbers' base and lock him in his cell.

-Meanwhile with SevenSeven, he was able to arrive at the destination he had agreed upon with his other companions.

-In a hideout in Undertown were Thunder Pig, Liam and Suemungousaur.

Thunder Pig: You're late SevenSeven *annoyed*.

Seven-Seven: Jjkgkdpñfk

Thunder Pig: Yeah, whatever.

-Thunder Pig feel something or someone is missing

Thunder Pig: Hey, where's Sunder?

Seven-Seven: Phfjdkfkfjjjjfd

Thunder Pig: Aaaggghh what was missing *slaps his forehead*, Well stay here guarding the door, I'm going to warn Liam and Suemungousaur that we'll have unwanted guests very soon *takes the bags from the robbery and enters the den*.

SevenSeven: Jkjfjjkfjkfjkfm

-SevenSeven was guarding the entrance until out of nowhere a blow hit him full in the face, knocking him out.

-Inside the lair

Thunder Pig: LIAM!!! SUEMUNGOSAUR!!!!!

-Immediately out comes a Chicken man and a giant lizard woman.

Liam: *cackles* What's up Thunder Pig?

Suemungousaur: Yes... What's all the fuss about?

Suemungousaur: It's the Good Guys, they captured Sunder and they're headed this way.

-This statement surprised Liam and Humongosauria a lot.

Liam: The - the - the good guys?

Suemungousaur: Oh yeah... they'll be coming over so I can play with my fists *clenches his fists*.

Thunder Pig: Calm down both of you, I've tasked SevenSeven to guard the door, if he is defeated and they get in, we must be on alert.

-Out of nowhere one of the metal doors of the lair came off its place with a lot of force, giving the impression that Kevin made of the metal of the door and Rook had already arrived.

Kevin: Knock, Knock, is anybody home? *defiantly*

Liam: *cackles* They're here *shocked and frightened*.

Suemungousaur: O Yes... My fists are going to be very happy *clenches his fists*

Rook: Give up, hand over the stolen items and we'll promise to cut your sentence in half.

Kevin: That's very cliché partner, but I agree with you *turns his hands into spiked balls*.

Thunder Pig: Grrr *looks at Liam and Suemungousaur* PROTECT THE LOOT!!! !!!! *looks back at Kevin and Rook* I'll take care of that pair.

-At that Thunder Pig pulls out his mallet with Spikes.

Thunder Pig: THUNDER, THUNDER, THUNDER PIG ¡¡¡¡AAAAAAAHHHHHH!!!! *he goes to attack both of them*

-Kevin acts fast and blocks Thunder Pig's punch.

Rook: I'll go for the....

-Immediately a giant fist comes out with the intention of hitting Rook, but he narrowly dodges it- 

Sumongosauria: Come on, let's get closer.

Suemungousaur: Come on, come closer blue guy and attack me!

-Suemungousaur goes straight at Rook with the intention of crushing him, but he dodges it very easily.

Suemungousaur: Stay still *angry*.

-In one of those dodges, Rook disappeared from Sumongosauria's vision.

Suemungousaur: Ah? Where did you go, blue guy?

-While Suemungousaur was distracted, Rook loaded one of the wall-destroying projectiles into his proto-tool with the intention of shooting her from behind.

Liam: *cackles* Sue-Sue-Suemungousaur CAREFUL!!!!

Suemungousaur: Ah?

-Suemungousaur realized it too late, as Rook fired his powerful shock projectile straight at Sumongosauria's back, causing her to crash into a wall causing it to destroy itself and knock Sumongosauria out.

Rook: Okay, one down, now I'll help Kevin with...

Kevin: No need Partner

-Rook finds Thunder Pig already defeated by Kevin.

Kevin: Now all that's missing is the Chicken man *looks at Liam*.

Liam: *cackles in fright* I-I-I-I.... *raises his hands* I GIVE UP!!!!

Kevin: Well that was easy

-After all this an hour passed, The packages and money were returned to Argistix Security the criminals were teleported to the plumbers base and arrested.

-Minutes later Rook and Kevin arrive at the Plumbers' base via Rook's ship.

-They arrive and park in the garage of the base where Gwen was waiting for them.

Gwen: Hi guys, how did it go?

Kevin: Fine as always beautiful

Rook: Although with a little difficulty

Gwen: I guess, I'm sorry for not going with you to help, is that I was trying to investigate the whereabouts of Dark Star.

Kevin: I see, after he transported Ben to a place we don't know about, That damn is very, very well hidden *crosses arms*.

Rook: Besides, without Ben's help, these last few missions have been a little difficult to accomplish.

Kevin: Although they are not impossible, I still don't understand who was the snitch that reported Ben's disappearance, since Undertown found out, all the criminals have started to come out of their dirty hideouts to commit their misdeeds.

Rook: We're getting a lot of calls from various citizens of Undertown who feel unsafe and alarms about robberies at Argit's company.

Kevin: You know, I'm starting to wish I wasn't helping Argit, although at the same time, I don't mind doing it, because we're doing him a lot of favors by returning his stolen packages, he knows he's going to have to pay me a lot for this.

Gwen: Yeah yeah whatever you say

-After that small talk, the three of them headed to the living room of the plumbers' base.

-In the living room

Rook: I still don't understand how Dark Star was able to hide his trail to avoid being tracked down.

Gwen: He can't do it, because he'd be relatively dead.

Rook: So I guess he's gone off planet then?

Kevin: I don't think so, Michael has nothing to do off planet, and if anything, if he had things to do, he can't afford any spacecraft to get off Earth.

Gwen: Then how come he could disappear?

???: With a portal

-These words made Gwen, Kevin and Rook look surprised.

-Suddenly Magister Patelliday appears in the Living Room.

Mgtr. Patelliday: The way that Dark Star disappeared from all radar is because he went through a portal.

Rook: Magister Patelliday, are you sure about that?

Mgtr. Patelliday: Of course, are you doubting what I'm saying?

Kevin: If so, how do you prove that the bastard went through a portal?

Mgtr. Patelliday: I knew you would say that, *turns around* follow me guys.

-At that moment Magister Patelliday leads Rook, Kevin and Gwen to the Plumbers base mainframe.

Gwen: Magister Patelliday, can you tell us how you deduce that Dark Star went through a portal?

Kevin: I'm curious too

Rook: Me too, Magister

Mgtr. Patelliday: Look at the screen guys.

-The three of them look at the screen that Magister Patelliday shows and indeed, on one of the screens there is a recording of Dark Star entering a portal at night.

Kevin: Hey it's true he went through a portal.

Rook: I'm sorry I doubted you Magister.

Gwen: How did you get those images?

Mgmt. Patelliday: Miss Tennyson, we are plumbers, it is normal that we have cameras strategically placed and well camouflaged throughout our sector to locate any crime or suspected criminal, we are space police, or did you forget?

Gwen: Ok maybe that proves he went through a portal, but he wouldn't go anywhere else but anywhere on Earth.

Mgmt. Patelliday: You have to be more observant Gwendolyn, look.

-Magistrate Patheliday plays the recording again and stops it at the exact moment Dark Star enters the portal.

Magistrate Patheliday: Do you notice anything unusual about Dark Star?

Kevin: Mmmm... He seems to be dirtier and uglier than usual.

Mgtr. Patelliday: WHAT? NO

Rook: Did he lose more hair?

Mgtr. Patelliday: NO

-Gwen analyzes the frame well and sees Dark Star is holding a very suspicious book with him.

Gwen: Is that the book he has in his hand?

Mgtr. Patelliday: FINALLY, if it is the book, we suspect that thanks to that book he was able to open the portal.

Rook: You know, now that I remember, in the last confrontation Ben had against Dark Star, he had a book in his hand.

Kevin: Now that you mention it, it's true, he did have a book with him.

Gwen: But Dark Star doesn't need a book to open a portal to go to another part of the earth.

Mgtr. Patelliday: It's not our Earth.

Rook: What do you mean Magister?

Mgtr. Patelliday: Look at the frame again, but this time at the portal.

-At that moment, Gwen, Kevin and Rook look at the frame again, focusing more on the portal.

Rook: It appears to be Undertown

Kevin: No, it's not Undertown, that neighborhood is underground, and that town seems to be in the open air, although by its facade it doesn't seem to be very modern, has it traveled to the past?

Gwen: Guys, take a good look, there seems to be life there.

-Rook and Kevin analyze Gwen's observations and look at a white dwarf creature with red hair and a big nose, a boy who seems to be a human with a kind of robe and a huge foot.

Rook: What are those creatures?

Kevin: Well, that rules out my theory that he went into the past.

Mgtr. Patelliday: Apparently, he not only used that book to open the portal, but to open it in the direction of what appears to be another world.

Gwen: Another world?

Mgtr. Patelliday: Yes, another world, why do you think we didn't detect Dark Star all over Earth and our sector?

Rook: Well that explains why we couldn't find Dark Star anywhere, he went to another world.

Kevin: And why did you tell us about this until now?

Mgtr. Patelliday: The recording of Dark Star entering the portal turned out to be of very poor audio visual quality, I called Blukic and Driba to improve the quality of the video, but you know how they are.

Gwen: Yes, it's understandable

Mgtr. Patelliday: I'm sorry to let you know about this information too late, when Magister Tennyson alerted us of Ben's disappearance, we had to search through all the monitors to find this Dark Star, don't think it has been easy.

Kevin: Well, we have a clue where Ben might be.

Rook: Magistrate, do you know where Dark Star opened the portal?

Mgtr. Patelliday: Indeed, we discovered that he opened it just outside this earthling educational center.

-On one of the monitors, the magister places an image of Friedkin University-

Gwen: It's my university

Rook: And the book I stole seems to be from there.

Kevin: Well, what are we waiting for? Let's go

-The three of them immediately leave the center of the base with the intention of going to the barracks garage.

Gwen: Thank you Magistrate Patelliday *runs off*.

Mgtr. Patelliday: It was a pleasure to help you guys, I hope you are successful in finding Ben.

Will Gwen, Kevin and Rook be able to decipher Dark Star's whereabouts and find Ben in the process?

Will they figure out where in the Multiverse Dark Star went when he opened the portal?

Find out in the next chapter.

I hope you liked the chapter.

-------------------------------------------------------

It should be clarified that this and the next chapter will replace the chapter of The Owl House that follows the previous chapter of the original story, «Sense and Insensitivity», I decided to omit that chapter, as I felt it was unnecessary for the story, it focused too much on things that had nothing to do with our hero and also, there would be no way for Ben to interact so much and make him use more than one alien.

If there are people who had still expected to see that chapter in the fic, then take it that everything, absolutely everything happened as in the original story and that Ben would have stayed in the Owl House because little and nothing had to do with him. I hope you respect this decision I made. And that instead, I wrote 2 totally original chapters from the Omniverse dimension not to leave aside the attempt of Gwen, Kevin and Rook in rescuing Ben, I hope you liked this effort :D

-------------------------------------------------------

Remember to support the chapter by giving them lots of stars and encouraging comments, with me it will be until next time.

Bye....
