Hello my fellow readers, writers, and people who have been enjoying my stories so far, I'm back with not just a new chapter but a new story all together. I was just laying awake one night and decided to scroll the great site for a crossover of Ben 10 and Supergirl from the CW. Imagine my surprise that there was none even though there is so much potential for a crossover between these two shows.

Anyway I'll start out with Kara helping out in the Ben 10 universe and eventually somehow (I haven't decided how yet) Ben will be teleported along with Kara into her universe and pulled into all the craziness that will develop there. Anyway I don't really have anything else to saw at this moment so without further ado let's get this show on the road.

Kara's P.O.V.

It was just an ordinary day in National city which for me, currently in my alias of Supergirl, consisted of fighting off another of the white Martian which had reared it's ugly head. After punching it's lights out I called over the communicator "I just stopped it and I'm bringing it in" and the voice of my supervisor in the DEO J'oon J'onzz who sometimes took on the mantle of the Martian manhunter said "excellent work Supergirl."

After putting the white Martian in a containment cell that would negate it's telepathy powers to prevent it from convincing another member of the D.E.O of letting it out and then it running amuck, I went back out into the main room where a whole bunch of agents were typing in stuff on their own monitors and I walked up to J'oon and said "is there anything else that you need me for today."

He said "no other than that white Martian it seems there's nothing out of the ordinary here so go ahead and enjoy the rest of your day." I flew off the building from the roof as I usually do when I leave the D.E.O. and just as I was wondering what I was going to do with the rest of my day I saw a vortex open up in the sky.

However, at the speed I was flying I didn't just see I flew into it and the last thing I heard before I lost consciousness was J'oon calling out my name with concern in his voice.

(earth 10, a few hours later)

Once I had woken up the first thing I had felt was a massive headache coming on and as I tried standing up if it weren't for leaning on the table where I had woken up it would have fallen from my knees buckling in on me. After steadying myself on my feet I looked around and saw that I was in a non-descript looking warehouse that had pretty much nothing except the bare essentials.

I saw a light coming from another room and using my x-ray vision I saw that there was only one person and after quickly scanning the rest of the warehouse with x-ray vision again I saw that we were the only two people here. As I moved toward the door of the room where the light was coming from, I tripped on my cape and my outfit seemed looser than normal. Just as I was getting up the only other person in this warehouse came out of the room he was in and I saw for the first time that he looked like a fish.

As I got up he asked "how are you feeling" and I responded "pretty good except for this pounding headache" and he said "well that's not too surprising considering you fell from the sky and landed on your head." I said "what happened exactly" and he replied "you would have to tell me since I only saw you slam into the ground head first in front of this warehouse."

I racked my brain even though it caused the headache to intensify slightly and I said "in my universe I way flying over my city and this wormhole or vortex or something opened up right in front of me. I didn't have enough time to stop before I flew into it and almost immediately, I lost consciousness and then I woke up here" and he said "I'm honestly surprised you managed to survive.

With a blow to the head with concrete from what looked like 200 feet up would have normally killed anyone else" and I said "oh it's because I'm Krytonian." He gasped and I said "what's wrong with being a Krytonian" and he said "there's nothing wrong with it in fact I consider it an honor to be in the presence of a Krytonian considering the fate of the planet."

I said "how do you know what happened to Krypton" and he responded with "of course I would know it was news on the galactic scale." He then pulled a what looked like an iPad only with a clear back and he turned it on and tapped away on it for a second and then passed it over to me. I was shocked to say the least from what the article said.

On the article in bold said "General Zod enslaves Krypton" and I said "hold on that didn't happen at the time of General Zod coming to Krypton he was defeated and sent to the phantom zone." He then said "I'm afraid that it's true Zod had enslaved all of Krypton and put up a barrier around it so that no one could enter the atmosphere or leave."

I stated "how is that possible Krypton was destroyed when it's sun collapsed and pulled Krypton into it which caused it to explode in a supernova." He replied "as a plumber I can promise you that Krypton is indeed alive and enslaved and surrounded on all sides by an impenetrable barrier. According the records of the plumbers they tried every kind of tech in the known universe to break through it none of it worked."

As I was about to ask about these plumbers, I caught a glimpse of myself in a mirror that was in the corner and I walked over to it and I said "what happened to me." He said "to what are you referring" and I said "I'm a teenager again" and he said "what do you mean you've been a teenager since you landed head first in the concrete."

I said "no this is all wrong when I flew into that wormhole or whatever I was 30 years old and now I'm at the least 14 years old so I've lost 16 years of the life I've lived." He said "I don't understand are you sure that you're not just confused about how old you are since you did hit your head hard enough to leave a small crater in the ground."

I said "no I know I'm not here look at this" and I pulled my wallet out of the pocket that I had Winn sew into my outfit and opened it and showed him my driver's license. After looking at it for a second he handed it back and said "I don't know what happened to make you younger but I'll help you figure it out once I return."

I said "return from where" and he said "I'm going on a stakeout at the house of one of my old partners in the force" and I said "okay when you say force are you talking about these plumbers" and he said "yes the plumbers are the only law enforcement organization that are recognized by all signatories of the milky way treaty or at least in terms of earth we're space cops."

I said "well let me come along and I'll do whatever I can to help" and he looked at me for a second and then held out a disc with a red center and I grabbed it and said "what do I do with this." He then said put it on your chest and press the very center of the disc and you'll be in a plumber's suit since I'm giving you a temporary commission in the plumbers."

I did so and my old outfit disappeared and was replaced with a suit like his only without the water or whatever it was in his helmet keeping him alive. He then handed me another thing which was a mask and he held another one and I said "okay what's up with the mask" and instead of responding he put his on and in a moment with a blue lightshow he now looked like someone in a trench coat.

I said "okay how does that work" and he said "photonic displacement it can make you look like anything you want which in this case since you're insisting on coming with me pick something that can easily blend into the shadows." I placed the mask on the faceplate of the plumber's suit and instead of coming up with my own I went with pretty much an exact copy of what this guy picked only with a black trench coat.

As we were heading out I said "since I don't want to keep referring to you by guy what's your name if you don't mind me asking" and he responded with "Magister Labrid."

(one hour later)

We were sitting in the bushes of a trailer park and were watching what looked like a simple RV and after about an hour of sitting there a teenager with brown hair and wearing what looked like it could be a school soccer uniform came up to the RV we were watching and he knocked on the door and after a moment he said "Grandpa max open up it's me."

He then picked up a rock from the ground and pretty much right after opened the door and walked in and stayed in there for a few minutes. After said few minutes an ugly looking alien slammed through the windshield of the RV covered in white stuff like it was sprayed with a fire extinguisher. After another moment the teenager came out again and picked up his bike and rode off and Labrid said "come on."

We went inside and he started searching for something and I said "so what are we looking for" and he said "a watch with a green hourglass symbol on it and a black strap that would go around the whole wrist and lower part of the forearm." We searched for an hour and he said "that kid must have taken the Omnitrix with him when he left" and I said "so how do we find him."

He responded "we go to the local high school and hope he's there" and we took off in the direction of the local high school.

Ben's P.O.V.

After knocking that alien out of the rustbucket 2 by blasting it with a fire extinguisher I sat down in the driver seat and flipped a couple of the switches on the dashboard. After a moment and some mechanical hissing the clock in the rustbucket 2 opened and revealed a hidden compartment with something in it. I grabbed it and flipped the switch on the device it hummed and showed a hologram of grandpa max.

It started "hello ben" and I said "Grandpa what's" but it cut me off "I left this recording where I knew only you would find it. I'm in a bit of situation but it's nothing I can't handle certainly nothing for you to worry about there's renewed alien activity on earth I'm investigating." It then turned off before turning on again and said "oh and don't worry about the Omnitrix either I have it and it's completely safe they'll never get their hands on it say hello to your cousin Gwen for me love you max out" and it turned off again.

In shock and surprise I said "you have the Omnitrix" and I hopped out of the rustbucket 2 and got on my bike and rode back home. As I got off the bike I was running through the house to my room and I heard mom say "Ben don't run in the house" and I called back "sorry mom." I started digging through my closet and said "he says he has the Omnitrix I know it's in here somewhere" and I opened my box that contained my souvenirs from the summer road trip when I had first found the Omnitrix.

I pulled out some sumo slammer cards that had a rubber band around them and under them was the Omnitrix and I grabbed it out of the box and said to myself "what are you trying to tell me Grandpa." I rode my bike to the high school where Gwen went and just barely managed to see her win a karate fight and along with everyone started clapping and kept clapping until she noticed me and when she did, I said "so how's my favorite cousin."

She said "Ben" and hugged me and said "still undefeated compliments mean you want something" and I said "I got a problem I need advice" and she replied "sure just let me change" and after a few minutes I had dozed off and when I woke up again, she was leaning over me and said "well that's attractive" and I said "what I'm awake what" in my half-asleep state.

She said "you needed help" and I said "I need advice" and I showed her the Omnitrix and then as we sat down on the bleachers, I showed her the message from Grandpa. She said "but Grandpa doesn't have the Omnitrix you do" and I said "I know I think he's trying to send me some kind of message I think he wants me to put it on again."

Gwen then said "Grandpa always said that was your choice you don't have to if you don't want to" and I replied "I used to love the Omnitrix it made me feel special" and Gwen said "you know what it wasn't the watch that was special it was you" and when I looked at her she continued "and you earned the chance to have a normal life you put that thing back and that's pretty much it for normal."

I responded "but if Grandpa needs my help" and she said "he said he didn't beside remember how much trouble we had getting off the last time." The door to the gym in the school opened and a deep voice said "the Omnitrix ain't yours give it up" and I said "no way" and we ran toward the other exit.

Kara's P.O.V.

We went to the local high school and by the time we got there it was night out and Labrid said "where would they be" and I said "let me try something" and I pulled the helmet off my head of the plumber's suit. He said "what are you doing" and I said "I'm trying to listen for them Kryptonian's have better hearing than any other species that I know of.

I listened intently and I heard a guy's voice say "I used to love the Omnitrix it made me feel special" and I put the helmet back on and said "this way." I lead him to a metal door and he said "are you ready" and I said "of course" and he opened the doors and there were two teenagers in the room that we had entered. Labrid said "the Omnitrix ain't yours give it up" and the guy in the gym said "no way" and they both ran for another door.

As they got through the other door we both went after them and they got stopped by doors at the end of a hallway and Labrid took the front of our duo and said "give it to me now" and the guy we were chasing said "or what" and Labrid replied "or this" and he pulled off the mask he was wearing and I assumed he wanted me to do the same as well so I did so and the guy replied "oh that's so creepy."

Labrid pulled out his blaster as the kid began running in one direction and blasted the floor in front of his feet and it exploded against the floor but from what I saw didn't leave any damage and he said "don't make me use it on you" and the guy said "who's making" and the girl with him stepped up onto glowing pink platforms under her feet and lit her hands up with the same energy and she said "not fish face here that's for sure."

Labrid shot off 3 shots at her all of which she blocked with a wave of the energy that she was using that disappeared almost as soon as it blocked the shots. She then shot an orb like what was on her hands and it shattered against Labrid which caused him to drop the gun. She then shot a line of energy from both hands and had then hit us in the stomach area and then she lifted us into the air while landing on the ground herself.

The guy said to her "you're getting really good at that stuff" and she said "thanks" and then he turned to us and said "I want some answers right now otherwise" and Labrid cut him off "yeah" and the guy said "I don't know I'll overfeed you." Labrid then said "do I look like someone to joke with I'm a duly deputized agent of plumbers and intergalactic law enforcement organization."

The guy said "I know what they are my grandpa max used to be a plumber" and Labrid replied "Max Tennyson he was helping me on a case when he went missing" and the girl said "we're looking for him." Labrid then said "wait he's your grandfather you're the legendary Ben Tennyson" and the now named Ben said "I guess so."

Labrid in understanding now said "I thought you just some kid who snatched it from the rustbucket I guess I owe an apology" and while gesturing at the energy holding both of us in the air he added on "if you can get us out of these things maybe we can find your granddad together." Ben then nodded at the girl and she lowered us to the ground and the energy around us disappeared as if it was never there."

The girl then looked at Ben and said "Are you sure" and he then put this Omnitrix on his wrist and closed it so it looked like a perfect loop and he turned to her while holding the wrist that had the Omnitrix on it and said "I'm sure."

(2 hours later)

We went to what looked like an abandoned train yard and were crouching behind some crates on a raised up part of the yard. The girl who I later learned was named Gwen said "so what are we doing here" and Labrid said "stakeout according to a tip from your grandfather the forever knights a group of criminals" and Ben cut him off "trade in alien technology I know we've went up against them before."

Labrid then continued "they're supposed to show up here tonight to receive a shipment of illegal alien tech" and Gwen asked "who do they get it from" and Labrid replied "don't know max was going to tell me but then he disappeared" and then we heard a rumble of a truck and he said "someone's coming." It was revealed the sound was 2 trucks that when they were both facing each other they both turned the lights off along with the engines.

Then there was another rumbling that was a green sports car with 2 black stripes on it pulled up and the engine turned off. A guy in a black muscle shirt, blue jeans, and what looked like combat boots stepped out of the car. Obviously Gwen and Ben recognized him by the look on their faces and Gwen proved my suspicions when she said "that's Kevin."

Labrid asked "you know him" and Ben said "Kevin levin he's got superpowers I fought him all the time when we were kids" and Gwen added on "he ended up trapped in the null void a kind of interdimensional jail." One of the guys who was wearing robes walked up to Kevin and handed him a briefcase and he opened it and turned to the other group and said "money's here."

Labrid stated "well he's brokering the deal" and Ben said "why not you said it's illegal and the guys who were selling the weapons rolled a cart with crates on it and Kevin opened one after handing the case back to the forever knights and pulled out one of the weapons and said "As promised 4 dozen factory new laser lances.

Ether point energy module, antennae focus emitter, it's good for 35 minutes of continuous fire at .6 terawatts is that good" and he then powered it up and shot it at an abandoned train car and after a few seconds it exploded in a violent burst of fire and he finished his pitch "you tell me." Labrid then said in a raised voice "those lances are level 5 technology earth had only level 2" and Ben said "what happened to the whisper."

Labrid slid down the side of the raised up part we were on and we followed and held his blaster and his badge out and said "hands above your heads airbreathers by authority of the plumbers you're all busted." All of the ones selling the weapons reached their faces and pulled off masks like Labrid and I wore and they were revealed to be exactly like the one that Ben had blasted out of the windshield of the rustbucket 2.

As they started moving toward us Gwen said "oh that's just creepy" and I said "not to mention ugly" and Labrid said "Back off" and he shot the wood of the train tracks in the abandoned train yard and they caught fire. The aliens started backing away and I said "so what now" and he simply said "standoff" and Ben said "uh I don't think so the other guys are behind us."

They removed their robes and were revealed to be wearing armor under said robes and they were advancing toward us with the laser lances ready to fire at us. Gwen said "We are toast" and Ben said "no we're not it's hero time" and he activated the Omnitrix and slammed it down only for nothing to happen" and Gwen said "Ben" in an alarmed tone and in a annoyed tone he replied "Watch."

I said "we can't stand by and watch for you to do whatever the Omnitrix does" and I ripped the plumber's suit off and ran at the forever knights that were coming at us while my normal outfit was absorbing the shots from the laser lances and I punched each of them hard enough to send them flying into the walls behind them.

One of them got in a good shot at my back and sent me flying behind the aliens and Labrid was constantly changing his target between the knights and the aliens all the while the flames he had created were dying down. Gwen said "Ben seriously" and Ben replied "this is a really bad time for a reboot" and after trying turning the dial more he said "I got nothing" and Gwen said "maybe I do."

Gwen then shot two orbs of the energy she used at the knights and sent three of them flying to where they landed on their backs. Labrid was blasting the ground in front of the alien's feet to stop them from advancing and the knights had gotten up and started firing at us. Gwen put up a transparent shield made of the same energy which broke in 4 shots from the laser lances and I got up fairly quickly.

One of the aliens then got in their back to back formation and went after Ben while a few more were coming at me and I ran at them only for one of them to shot slime from their mouths which stuck my feet to the ground. Once they had gotten me complately covered in slime I used my ice breath at the slime which quickly froze it and I broke out of it and started blowing the aliens back with my ice breath.

They however didn't seem to be effected by my ice breath and I said "so you can handle cold what about heat" and I shot them with my heat vision which knocked one back a shot and they were struggling to get up." I then remembered how they all backed away from the fire when Labrid set the wood of the train tracks on fire and I called out "their weakness is heat."

While some of the remaining aliens had slimed up Labrid I went over to where Gwen seemed to only be able to shield herself from the forever knights. I then sent them flying into the air with my ice breath on them which froze the joints for the most part of their armor. As I landed next to Gwen she looked up at me and we both started running only for both of our feet to be slimed to the ground.

Instead of repeating what happened the last time the aliens then shot slime over my mouth to prevent me from freezing their slime before they continued sliming us both us. After a bright flash of green light a plant like being came out and of the way that Ben had been chased into and I saw the hourglass symbol on the chest.

He then stepped in front of the aliens that were guarding us and he said to them "get away from my friends" and he hit one with a left hook, another with a right hook, and third one with an uppercut which sent the rest of them fleeing having seen their comrades be defeated so easily. As they got in the truck and started driving off he ripped a pole out of a support and swung it at the truck like a bat and tipped the truck over on it's side.

He chuckled and said "I forgot how much fun this is" and the forever knights then started shooting at him which he said "hey cut it out that tickles" and they continued firing. As he tried advancing toward them one of them got lucky and sliced one of his arms off and he said in shock "hey" after a moment he managed to reattach the limb as if it had never happened.

He then ran forward and knocked them out and I had finally managed to get enough air in my lungs through my nose to use my freezing breath on the slime over my mouth. It instantly froze and broke apart and I used my freezing breath to freeze the rest of the stuff around me and broke it easily. I then did the same for everyone.

As he was about to charge after the retreating forever knights Kevin got in his way and said "hey Tennyson." Ben responded "what do you want" and Kevin replied "let's see you trap me in the null void for all those years" and Ben cut him off "you did that to yourself" and Kevin continued "and you ruined my deal today I'm thinking I want revenge.

The good news is since I can absorb anything I have more than enough power to take it" and he touched the metal of one of the train tracks and after a moment he was completely covered in metal. Ben said "that's new" and both of them ran at each other and tried to punch each other although Ben's punch went over Kevin's head and Kevin's punch went right though Ben's plant like body.

As Kevin was struggling to get his fist out of Ben's body Ben spread his arms out and slammed them together on either side of Kevin's head which seemed to cause him some discomfort and Ben then kicked him in the stomach with enough force to send him flying into another train car. Kevin quickly recovered as he got up and picked up the train car and threw it at Ben which hit him head on.

Kevin seemed to think he was victorious as he walked up to the train car and said "and that's what happened when you mess with me." Ben then popped up behind him as a vine that was quickly reforming his whole body and Kevin said in shock "hey what" and Ben said "peek-a-boo" and landed a double punch on his face which sent him reeling back toward another train car.

As he lifted it above his head ready to throw it at Ben, he lit his hands on fire and shot them at the train car which exploded and knocked Kevin down for the count. As the metal left his body Labrid walked up to him and pulled a device out of a pocket of his plumber's suit and pointed it at Kevin and cuffs that looked like they were made of energy appeared around his wrists.

As Kevin regained consciousness Ben had just transformed back and he tried struggling against the cuffs and Labrid said "energy cuffs you can't escape ain't nothing there to absorb." Ben then said to Gwen "you still got some of that stuff in your hair" and Gwen put her hand through one side and Kevin said "other side" and she put her hand on the other side and after a disgusted look on her face she quickly pulled her hair out and pulled the rest of the slime out of her hair.

Labrid then walked closer to Kevin and said "time we had a talk tough guy" and he held up one of the laser lances and said "these weapons run on either point energy cells, a technology way to advanced for humans, they shouldn't even be on this planet." Kevin said "so how's that my problem" and Ben said "while we were fighting the forever knights got away with a crate full of them."

Labrid added on "you're in a lot of trouble son I'm giving you a chance to help yourself here" and as it seemed like Kevin was going to be unresponsive to this Gwen kneeled down next to him and said "Kevin people could be hurt." He got a smirk on his face and said "you don't have to convince me those guys ran off before I got paid I'm happy to help find those deadbeats."

They all got in his car and I was flying above it and I was able to hear the whole conversation with my advanced hearing and so far it seemed to be silent and Labrid started the conversation with "still think I should drive" and Kevin said "nobody drives the car but me" and Gwen said most likely to Labrid "you were telling us about the aliens."

Labrid said "I don't know anything about the ones we fought today never met that kind before" and Ben who I could see going through the Omnitrix said "I don't see them in here not that I know how to work this thing anymore." Kevin got a jibe in at him "maybe after you get your license pee-wee" and Ben retorted "oh who won our fight again oh I remember me."

Labrid cut into their confrontational discussion and said "there's been a lot of alien activity on Earth lately don't know why your grandfather thought maybe the weapons deal would lead us to whatever is causing all the interest now he's missing." Gwen then cracked a joke "knowing Grandpa max he's in a restaurant somewhere enjoying a roasted cockroach salad it's a wonder all that weird food didn't kill him." Ben however didn't react well to that "he's not dead stop making jokes about him" in a raised voice.

Kevin then pulled over and pointed to him while looking back "don't talk to her like that" and Ben started to retort "I'll talk to her however I" but cut himself off. He then continued "you're right I'm sorry Gwen" and she responded "I know you're worried about Grandpa" and he said "I just wish he were here he would know what to do he always knew what to do."

Labrid then said "well he aint you're the one with the Omnitrix you're going to have to figure out how to get things done on your own." Kevin then continued driving and it seemed to be in silence until they pulled up to a castle and Ben said "subtle nobody would think to look for knights in here" and Kevin said "you didn't" and as they got out of the car Labrid said "how are we going to get inside" and I said "I've got this" and I forced the drawbridge down and we all started walking in.

Gwen then lit the way with energy that she formed around her hands and said "there's no one here are you sure this is the right place" and Kevin said "there's a hidden door keep looking." He then went and observed some of their treasures and he pocketed a few necklaces and Ben caught him in the act as he was observing a chalice and he said "maybe you should have brought a shopping cart."

As he was looking at suits of armor as if they were combating each other Ben said "I don't like the looks of this." He backed away into another suit of armor which caused it to start falling and the sword it was holding was about to hit him if it weren't for his quick reflexes and as the armor and sword clattered to the stone ground Kevin asked "come on man what are you doing."

Ben then replied "sorry guess I'm just a little paranoid" but the last word came out as a slightly higher pitch since he only just then looked behind him and saw a dragon towering over all of us.

Yet another chapter done in the next chapter we'll be going over the events of the episode of Ben 10 Alien force titled Ben 10 returned part 2. As I said this is to make up for the communities lack of Ben 10/ Supergirl crossovers. I know that Kara would normally be considered overpowered in the Ben 10 universe but that's why I had the vortex age her down.

While it isn't stated in this chapter while she knows how to use her powers since this takes place in at least the middle of season 2 of Supergirl maybe even season 3 I haven't decided yet. However the kicker in this case is that her power such as her ice breath, laser vision, and flying and everything else is nerfed by the fact that I had the vortex that she flew into de-age her into her 15 year old body.

Anyway I don't have anything else to add so until next time this is Diamondholder signing off.
