(Author's note) this is my first attempt at a fanfiction story and I hope you like it.

this is a crossover between Ben 10 and Monster High. Where Ben was sent to another dimension, where it's a world that has monsters instead of aliens.

I'm a Ben 10 fan so I thought this would be good to start my first fanfiction story, although I'm not really a fan of Monster High, I just thought it would be a good choice and to use for this crossover, so without further ado let's begin the story.

disclaimer, I do not own anything Ben 10 related or Monster High related. Both shows are owned by their respected creators.

Prologue

In the Ben 10 universe at around 6:55 AM -

It was a normal morning in Bellwood. The sun was Rising, people were waking up and getting ready to start the day and eating breakfast, people were going to work, nothing at all can ruin a morning like this.

BOOM!

Well almost nothing. That explosion came from a bank that was being robbed by 2 aliens, the 1st out of the two of them was a tall and a bit fat male that had a hat that he wears backwards, a pair of gray goggles with green lenses on his head, on his hands were a pair of yellow gloves, he wears red overalls with the pocket half tired on the chest and a black belt, he has black sideburns, he has yellow eyes and he wears black cowboy boots, this is Boyd a dimwit out of the two. Hay octagon we hit the jackpot didn't we? Said boyd.

The 2nd one now identified as Octagon was the smarter one out of the two, he was a tall but small out of the both of them male who was skinny, who also wears a hat but the right way, he also wears yellow gloves and where's gray goggles with green lenses, he as well even wears red overalls and with a fixed up pocket on his chest, he he also wears a black belt, he also has black sideburns and yellow eyes, he even wears black cowboy, and to top it off he also wears a yellow and black jacket with a bit of red where the elbows are, these two were the Vreedle brothers.

Ya said it brother, said Octagon to his brother. We hit the jackpot indeed, we'll use this money to get us some new toys from the Black mark, if ya know what I mean.

Boyd looked at octagon with a raised eyebrow in confusion. I didn't know they sell toys in the black mark, if ya having trouble sleeping at night I'll lend ya my Mr. Teddy to ya if ya want? Octagon looked at his brother with annoyance. No you idiot, I mean like weapons like blasters. oh said boyd. And once we get the weapons we need, we'll use those weapons to get a bigger score than today, he said to his brother. Now let's get out of here before that boy and his friend gets here.

Hay that boy has a name you know, and that friend isn't just a friend, he's my partner. said a male voice from behind them as they turn around to see two people, a 16 year old and on the teens left was a gray/blue like alien, the 16 year old on the right, was a male teen with brown hair, green eyes, and a black T-shirt with a green line running down the front of the shirt, with the number 10 in the middle of the green line, a pair of brown pants and green and white shoes and on his wrist is a white and green watch with a green hourglass symbol on it, but this isn't just a normal watch, and the boy who's wearing the watch isn't a normal teen. this is Ben Tennyson, the Hero of earth, the Protector of the universe, and the Savior of the timelines, and also the wielder of the most powerfulest weapon in the universe, the Omnitrix.

And Gray/Blue like alien on his left had black tattoo like marks on his face, he had yellow eyes with some orange in it, he had elf like ears, he wore a a black and dark blue armor like suit with a blaster like weapon on his back with the same green hourglass symbol on it like the Omnitrix. This is Rook Blonko, he is apart of an alien species known as Revonnahgander, and he is also a plumber, and no I don't mean the ones who fix toilets or leaky pipes.

Aww man, it's that Tnnyson kid again and his plumber friend, and here I thought this would be easy. said Boyd with some irritation in his voice. That's right you two, we are here to stop you, Ben said with a smirk on his face. By order of the Galactic-Plumbers, you two are here by place under arrest for destruction of public property, and for stealing money from the bank, said Rook with a serious face, while grabbing his Proto-Tool from behind his back and pointing it at the brothers.

Ummm hay Octagon what should we do now? said boyd to his brother. What do ya think ya idiot, blast them, Said octagon with a look of irritation on his face because of his brother's dumbness, as both him and his brother point their guns at ben and rook. Well I guess getting them to surrender had just went out the window, oh well I guess there's nothing we can do now Ben said with a shrug, you ready partner. Ready as always said Rook.

Then let's do this, ben said as he Scrolls through the alien selection, IT'S HERO TIME! Ben shouted as he slams his hand on the watch, injecting alien DNA into his blood, transforming him into something else. The veins on his arm where the Omnitrix is, started to bulge and the new DNA flowed through his veins all throughout his body, his arms quickly turn from its normal color to a light blue color, with a spike coming out of the elbow and his fingers transforming into three black claws on each hand, his legs transforming into Raptor like legs and his feet turning blue and his toes fusing together until only 2 are left, were a black orb Sprouts from his feet, where now standing on both of, them a black spiky helmet forming on his head and a face plate with a blue X shape lens went down, blocking his face from view, then a full black suit formed on his body with a green line going down the front of the suit, a black tail with blue stripes then forms on his backside, his face plate then goes up showing off a blue face with gray eyes and lines going through both his eyes and mouth, and to finish it off the Omnitrix symbol forming on his chest, completing the transformation.

XLR8, the Kineceleran shouted in a raspy voice ready to run circles around the Vreedle brothers with his crazy speed. Let's do this, without another word the kineceleran's face plate went down and he ran to Octagon, and then he shoulder tackled him to the ground, then he stopped running to look back and smirked, while Boyd was shooting at Rook hoping to hit the Revonnahgander, rook had turned his Proto-Tool into a some sort of sword so that he can use it to fight , that or deflect the blaster bullets away from him as he charges towards boyd.

Rook seeing a opportunity he deflected one of the Blaster bullets right back at Boyd hitting the barrel of the blaster directly causing it to explode, making boyd with a surprise expression on his face drop the now broken and smoking blaster.

Seeing that his blaster is now unusable, looks up to the smirking face revonnahgander with angry look on his face then started running towards him preparing to punch him, with that rook then stopped smirking turning his Proto-Tool back into a blaster and then putting it back on his back, as boyd got near him and threw a punch, rook move to left and dodged the attack, then he threw his own punch, hitting the aliens criminal in the face making him stumble back a bit, rook threw another punch, but this time Boyd caught the punch, shocking the revonnahgander, with this aliens criminal smirked at him and them punch him in the face while making him hit the ground and go sliding.

With XLR8 and Octagon, XLR8 being to fast to be hit, and Octagon getting irritated at the fact that he can't seem to hit the Kineceleran, and to make things more annoying he is running circles around him, literally.

You're too so pal, try better. Said XLR8 as he run literal circles around him, Octagon was fuming, he couldn't seem to hit him at all, he just kept running and running and running and running and running and running and running and running, and it was getting really annoying but, just then Octagon got an idea, he then pointed his blaster at the ground where the Kineceleran after image feet was at, he them blasted the spot hitting the ground causing XLR8 to fall to the ground and rolled a bit, XLR8 got up dazed a bit rubbing his head, the kineceleran looks up to see Octagon standing in front of him with a smirk on his face where then he back hand the fast alien, making him slide all the way towards where his partner was, then he walked beside his brother who was also smirking.

Both the Kineceleran and Revonnahgander looked at each other. Want to switch? Said XLR8 to rook. Yes let's switch. Said Rook as him and XLR8 got up, and the kineceleran then smiled.

Then let's go. Said XLR8 as he his the Omnitrix symbol forming on his chest, turning him back to normal for a quick second then feeling new alien DNA being injecting into his blood, transforming him into something else. The veins on his arm where the Omnitrix is, started to bulge and the new DNA flowed through his veins all throughout his body, he felt his size get a bit bigger, then he felt all his hair disappear, being replaced by a black line that ran through the front of his face and on top of his head where his hair used to be, then both his eyes split where now he has 4 green eyes on his face, the his toes on his feet then fusing together until there is now 2 toes, he then felt another pair of arms Sprout from his sides, giving him now 4 arms, then a Black and Green sleeveless shirt then sprouted on his body alongside black pants, then his skin quickly turn from it's normal color to a light red color, and to top it off the Omnitrix symbol forming on his left shoulder, completing the transformation.

FOUR ARMS! shouted the Tetraman with 4 of his arms in the air. Let's russell big guy. Is all Four Arms said as he slammed his 4 fists together and then charges at Boyd pushing the alien criminal back a bit, while Rook charges at Octagon ready to fight, not wanting his blaster to be blown up like his brother's blaster, he threw it and brought his hands up into a boxing like position also ready to fight.

With Four Arms and Boyd they where hands at each other punching and hitting one another, at least one of them was hitting his opponent, four arms has the upper hand while the aliens criminal was not, even though he's strong, he isn't stronger then a Tetraman as he thought, and he learned this when he added in his two other extra appendages, making this fight a somewhat one sided fight, and with 2 hits to the chest and a quick upper cut by a 3rd arm, boyd was send to the ground sliding and once he stopped he was out cold.

With Rook and Octagon they were having a somewhat boxing match with each other, both throwing punches at each other, both dogging each other's punches while landing some hits on each other, then the Revonnahgander caught the punch surprising the alien criminal, with a smile he punch Octagon making him dazed which gave rook a opaning the he needed to deliver a spinning kick to the alien criminal sending him flying towards his brother making him laying on the bigger alien, knocking him out

At this, both the Vreedle brothers were now defeated. Well. Said the Tetraman while the Omnitrix symbol was blinking red a couple of times and then Ben returned back to normal. That was that, we stop the bad guys once again ain't that right? Ben asked his partner. Indeed, another good job well done. Said the revonnahgander to his partner. Now we should get them back to plumber base and into a cell. Sure, and we should stop at the Donut shop and get some donuts for breakfast because I'm hungry.

Little did Ben know, that today will be the day that his will change.

In the Monster High universe at around 7:09 AM -

It was 7:09 AM in the morning in New Salem, some monsters were waking up at this time, while some just now are waking up, while some were eating breakfast, and some were getting ready to go to Monster High, a school that is for monsters that want to live a normal life, and to one day live in peace with the Normies, one monster in particular was still sleeping but instead of her bed she's instead sleeping on a desk that is in her room and she's now waking up.

She's a monster with light pale green skin with some stitches on her arms and legs to her neck and her wrist and ankles, she even has some stitching under her right eye on her right cheek, she wears a black with some white school girl uniform with a black tie, she wears black high heel with white stripes, she wears 2 purple skull like earrings, she has 2 screws on her neck, she has red lips, she has black hair with some white strips in it and she has 2 different eyes, a Blue 1 and a Green 1, this is Frankie Stein, the daughter of Frankenstein's monster, and a student of Monster High.

Frankie woke up with lazy and tired eyes, she has been up all night doing her Boo Quiz that she was given from one of her classes, and she had finally finished it. It had been at least 11 days since she started at monster high, when she first started school it didn't turned out good as she wanted on the first day, but it got better on the second.

She made 2 new friends at the start, Clawdeen and Draculaura they became her first friends she had, she also tried out for the Fearleading, it didn't go so well because thanks to a loose thread her foot went flying and Landing into a smoothie belonging to Ghoulia, causing it to go everywhere, including captain of the fearleading team her self Cleo, however the mummy girl had decided to give frankie another chance and as such she was in.

She even became friends with Cleo, a sea monster girl named Lagoona and the zombie girl named Ghoulia, so far the past 11 days have been pretty good. When frankie woke up a bit more see seen the time on her clock, and it said 7:09 AM but then it went to 7:10 AM, seeing what time it is she woke herself up even more and then went to do what she usually does for when she gets ready to go to school.

After she was finished getting ready, she left her room and went to the kitchen, she expected to see both her mom and dad that's or one or the other, but instead she saw you have to Kitchen, with a race eyebrow, she looked at the kitchen wondering where her parents were, then she saw what looked like a note and it was address to her, she opened the note and stated to read it.

Dear Frankie

your father and I left the house because your father was asked by someone to help him with something, I went with him because your father needs to update his license which means he can't drive until he does that, so I have to drive him, and we won't be back until late at night at around 12:30, I made you some breakfast and there is some easy to make food in the kitchen, and please don't say up to late again

Love: Mom

Well at least I know were dad and mom are. Said frankie now knowing where her parents are at. oh well, time to eat my breakfast and then go to School. After eating her breakfast, she then was ready to leave, as she is about to walk out the door, she then looks down and sees what looks like a envelope on the welcome mat, and it's addressed to her, with a confused look on her face she picks it up, then she opens the envelope and pulls the letter out and then starts reading it.

To: Frankie Stein

if you are reading this then you must go into the woods near your school, there you will find another Envelope with another letter it is important that you read the letter. I've given you directions to the specific area were the envelope is and you'll find, good luck.

Heroes come in all shapes and sizes and they aren't born they are made, but sometimes they are born, when it's there destiny.

Frankie was now confused, where did this come from, who send her this and who wrote the letter, she then shut the door and then went to school.

A minute later.

Frankie had just got to Monster High, she was now looking for her two friends, class is about to start and she needs her friend's opinion the letter that she got. Hay Ghoul over her. Said a female voice shouting to her and got frankies attention, there she sees two of her friends standing there waiting for her.

On the left was a monster with light brown fur, she wears a small jacket with long sleeves, she wears a purple skirt, she wears a pink shirt with black stripes, on her neck is a black choker and a gold and brown necklace, she has wolf ears with 2 earrings in each ear, she has red lips and and she also has wolf like fangs popping out, she wears purple and black high heel boots, she has brown hair and she has brown eyes, this is Clawdeen Wolf, the daughter of the Werewolf Man, and she is both a student of monster high and a friend of Frankie's.

The second one on the right is a monster with pink skin with a dark pink heart on her left cheek underneath her eye, she wears a white dress with a dark pink Fest, she wears drak pink and black high heel boots, she has black hair with dark pink strips in it tied up in two ponytails, she has paper clips as earrings, she has dark pink lips with vampire fangs popping out, she a black and gray umbrella with a witch hat as the handle and a gray skull on top and she has purple grayish eyes, this is Draculaura the daughter of Count Dracula, and she is both a student of monster high and a friend of Frankie's.

Hay ghouls. Frankie said waving at her friends. I've been meaning to talk to you guys about something. What is it frankie? Asked Draculaura. Well I found this letter in front of my house just laying there and it's really weird.

Let me see it. Asked Draculaura wanting to see the letter, when she read it she raised a eyebrow out of confusion, yeah that's really weird. Do you know who wrote it? No, however wrote this didn't want to tell me exactly who they are. Frankie said wondering who exactly ruled her this note and why does she need to go to the woods to look for this other letter.

Hmmm let me see it. Said Clawdeen as frankie hands her the letter, clawdeen then starts sniffing the letter to try to get the scent of who wrote it. Well Draculaura asked. Nothing, I can't seem to smell the scent of who wrote this thing, with that she then handed frankie back the letter. Who even send you that? I don't know clawdeen, maybe we should go to the location. Said frankie to her friends. Are you sure Frankie, I mean for all you know who ever wrote it is messing with you. Clawdeen said. Or maybe this normie or monster wants to be mean. Said Draculaura with worry. Well probably but how would we know if we don't find out?

Clawdeen sighed in defeat.

Fine frankie we'll go during lunch, because I'm not wanting you to try to do it during class. Alright then it's settled we could maybe get cleo an ghoulia in on this if it's possible, although I really don't know if getting Cleo involved. Said Frankie with a sigh.

Back in the Ben 10 universe now at around 8:55 AM -

At Plumbers base, the Vreedle Brothers were being take there cell's buy some plumber agents, while Ben Rook and Max watch as the brothers get placed into cells.

Good job you two, you managed to stop those two. Said Max to his grandson and to the revonnahgander. Yeah well grandpa, they are sometimes difficult to deal with at times, but we always beat them no matter what. Said Ben with a proud smile.

What if Dr. Animo worked with them? The Revonnahgander asked with a raised eyebrow.

Then we deal with the three of them. Ben said

what about Albedo? He asked again.

HA I doubt that would ever happen.

What about Vilgax? He asked once more.

Ben raised eyebrow at that. Why would vilgax ever work with those two, I mean I get if it was Albedo, but why those two. Who knows ben it doesn't hurt to think of the possibility. Rook said to Ben making him think a bit.

Hmmm, okay probably, but I still doubt it. Well as much as I want to talk about more about possibilities or what ifs I have to get going. Said Rook. Huh wait why? Asked Ben in confusion. You see ben it's because my sister finally graduated from the plumber academy here on earth, and I thought it would be a good idea to take me and her back to are home planet to celebrate her graduating from the academy by doing a celebration with a family or the Earth term for it, a small party, plus it's considered my vacation week. Rook said with a smile on his face.

Ben looked at rook and smiled. That sounds good to hear, well all I have to say is congrats to your sister and have fun hanging out with your family.

Rook smiled back at ben then he held out his hand in a fist, wanting to give him a fist bump, then Ben gave him a fist bump, with that rook then walked off leaving ben standing there watching the Revonnahgander leave.

And there he goes for his week vacation with his sister. Said ben. Maybe you should have a break today, you haven't had a break in a while. Said Max to his grandson.

Ben thought on that, it has been awhile since he had a normal day were he didn't have to fight, his last time he tried to have a break from his job of being a Hero was 4 months ago, he was hanging out with rook at Mr. Smoothies, but then his future self from the future showed up asking for help with dealing with Maltruant. Maltruant was going to use his own version of the Anilarg, he wanted to go back in time to the beginning of time to use the anilarg to recreate the universe in his own image and rule over it, even though he stopped Maltruan with rook, after that he really hadn't had a good break since.

Yeah your right grandpa, I haven't had a break in a while, I'll take a break. Said Ben with a smile. Well then I'm off, bye grandpa. Bye ben, have fun with your break. Max said to Ben while waving goodbye to him.

A hour later.

Ben was currently sitting at a seat at Mr. Smoothies enjoying a smoothie on his day off, at least he is trying to enjoy it without having to worry about saving the day, however the universe has other plans for him, he had to stop 2 criminals from stealing some rich kids car, he had to stop a purse snatcher, and then he had to stopping escaped Criminal from plumber base, now he is sitting down drinking his smoothie while wearing both his greenish jacket (it's the one he wears in omniverse) and he's wearing over it his green jacket (it's the one from both Alien Force and Ultimate Aliens), a bit tired.

Man and here I thought I was going to have a day off from hero stuff and it's now 11:10 AM, well I'll go get some chili fries for lunch and hope no one will try to do some bad guy stuff. Ben said with a sigh.

DING!

Hm, I got a text, who texted me? Ben asked himself when he got out his phone to see who texted him. Oh it's gwen let's see what she said.

Phone Text Messages

Gwen: Hay ben how are you doing?

Ben: Well I'm doing good, what about you?

Gwen: Well me and Kevin are at some burger joint that kevin suggested, we're currently eating right now and once we're done I'll be heading back and get ready for my next class after lunch.

Ben: Man lucky for you, your just eating and not dealing with any criminals whatsoever.

Gwen: Having hero problems?

Ben: In a way yeah, I'm trying to have a day off for today but I have to deal with things like 2 criminals trying to steal some rich kids car, a purse snatcher and I had to deal with an escaped criminal from the plumber base, so in a way yeah I'm not having the best day off.

Gwen: Yeah sounds like it.

Ben: Well enough about my hero life, how's college going for you?

Gwen: Well it's okay, I'm passing my classes and I've decided to join the chess club.

Ben: I didn't know you liked chess?

Phone text messages ended

Well I guess it's time to go get myself some Chili fri- . Before ben could finish what he was going to say, a portal appears right in front of them. Wow what is this, is...is this a portal? Ben said in confusion.

Then all of a sudden the portal started sucking him in. Oh crap I'm getting sucked in. Said ben trying to keep himself from getting sucked in. I know I'll turn into XLR8 and try to- . Before Ben could finish what he was saying he them starts getting into the air and quickly flying towards the portal.

What the- , is all he could say before he was sucked into the Portal and then the portal closed, and just like that Ben Tennyson was gone.

In the portal tunnel.

AAAAAAAAAAAAAAA, WHAT IS GOOOOOOING OOOOOOOOOOOON! Ben said in panic.

In the Monster High universe a few seconds earlier.

It's now lunch time at monster high, every Monster is eating whatever they have in the Creepateria, however some monsters aren't in the creepateria, that being a group of 5 monsters.

Okay Ghoul's it's up here. Said Frankie being the leader of the group.

Aaahhiaa? Said a monster that was a zombie. She had grayish skin, she has dark and light blue hair, she wears a small red and white shirt with cherries on it, under a red and black striped shirt with the sleeves of the shirt stopping at her elbows, she wears a fish net like under her shirts, she wears crimson red pants and black high heel boots with red shoelaces with the monster high logo on it, she has a green headband in her hair, she has red zipper as earrings, she has red lips, she wears white glasses and to top it off she has blue eyes, this is Ghoulia Yelps the daughter of a zombie, she is a student of monster high and a friend of Frankie and she is a smart zombie.

Well ghoulia she says the letter just showed up and clawdeen said she couldn't seem to smell the sent of whoever wrote it. Draculaura said to the zombie girl.

Yeah well let's hope this isn't a waste of time. Said Clawdeen with a sigh.

Yeah because I wanted to spend time with with Deuce at lunch. Said a monster that was a mummy. she has tan skin, she has brown hair with what looks like a golden Tiara of shorts, she wears a silver bracelet on her right wrist and she has some mummy bandages wrapped around her left arm, she wears mummy bandages like a sleeveless shirt and pants, she wears a small blue sleeveless jacket she wears brown mummy like high heels, she wears a golden belt and a golden choker on her neck, she has a small blue diamond on her face under her left eye, she has big golden earrings, she has red lips and to top it off she has light blue eyes, this is Cleo De Nile the daughter of the Mummy, a student and friend of Frankie and a princess of the De Nile family.

I just want to see why I was asked by the mysterious person to look for this other notes and see what's so special about it. Said Frankie.

Aaaaaahhaa? Ghoulia said with a race eyebrow. Yeah I have to agree with ghoulia on this, should we trust this this person. Said Clawdeen. We don't even know if person is a Normie or Monster? Maybe but I want to take the chance and see if it's bad or not. Frankie said with a determined look on her face.

With that the Ghoul's continue on their walk to the spot for the map leads. Okay we are here now where is that other letter. Clawdeen said looking around in the opaning of in the woods. Oh look there it is right there, in the middle of the opaning. Said draculaura pointing at the letter laying on the ground. Fang-tastic, now let's see what the letter say. Frankie said.

Now hold on frankie, clawdeen smell the air and tell us if there's anyone in the area. Cleo asked the Werewolf girl to make sure that there isn't anyone here watching them.

Sniff sniff, Clawdeen smells the air to see if anyone else was in the area besides her and her friends. I smell no one else besides use ghoul. Says the Werewolf girl to cleo.

Okay now I'll get the letter. Frankie said bending down to pick up the letter.

To: Frankie and friends

Wait did who ever write this knew that we would join Frankie in finding the letter? Asked Draculaura in a surprise and scared voice.

Okay that is really to suspicious. Says Clawdeen. Who even wrote this letter? I guess we'll find out. Frankie said as she opens the envelope and starts reading.

Dear Frankie if you and your friends are reading this letter that mean you chose to find out what is in the letter, well you must take the paper from behind this letter and reading it out loud, once you do something special will happen.

(turn the paper)

Frankie then turns the paper around and starts to read what's on the back.

A Hero is always saving the day, but a real hero is someone who would save everyone and anyone even if they have to give up something.

Okay that's really confusing. Says cleo with a confused look on her face. Who even is this and mystery person, and what does it mean something special will happen? I guess we will find out. Says frankie.

Are you sure about this frankie? Draculaura asked her friend. Yes I'm sure. Frankie says as she takes the paper that she was told read it.

Written backwards.

I ksa rof eht rewop ot nommus a noipmahc on a oreh enoemos ohw lliw pleh su ot taefed live.

The wind started to pick up and blow faster and faster.

Won I ksa rof ot nommus eht oreh ew deen os I llac htrof A OREH!

Just then the wind stopped blowing. So wait that's it clawdeen ask after a second. Aaahhiighaa. Says the zombie girl seeing that nothing happened. Well that's just great, this was a waste of time. Cleo said and very annoyed town. Come on Ghoulia let's go back to the creepateria and get something eat, there might be something good there. Aaaah. Said ghoulia as she starts to follow the mummy girl.

Well Frankie, I guess you were being messed with since nothing happened. Clawdeen shrugs as she walks off with Cleo and Ghoulia. Aww man I guess you're right, and here I thought we were going to see something special. said frankie with sad sigh.

Well at least we now know that it was fake right. Draculaura said try to comfort her friend. Yeah I guess you're right let's just go. Frankie says as she and draculaura walk to try to catch up with the others

CrAcK!

Frankie just heard of the sound of crackling lightning in the air. Ummm ghouls did you hear that? What do you mean frankie I didn't hear any- . Is all the Werewolf girl could say before she also heard what her friend heard.

CrAcK CrAcK!

What was that. Draculaura asked also hearing the sound.

Aaahhhiigghhaaa. Ghoulia says as she points behind the group making them turn around. Wwwwhat is going on. Says draculaura getting scared

CrAcK CrAcK...CRACK CRACK CRACK CRACK CRACK CRACK CRACK.

The Lightning started to get bigger then the wind started to pick up again becoming faster and faster.

Ummm Ghouls remember what the letter said that something special will happen, well I think that something special is happening. Frankie says as the Lightning stopped crackling and the lightning is now in the form of a lightning ball the the ball of lightning started to spend in a big circle.

Swish...Swish...Swish..SWISH SWISH SWISH SWISH SWISH SWISH SWISH SWISH SWISH.

the ball started to pick up speed.

SWISH SWISH SWISH SWISH SWISH SWISH SWISH SWISH SWISH...VOOOOOM!

Then right before them was what appeared to be a portal of sorts. Oh my Ghoul, wwwhat just happened. Draculaura said a bit scared. Aaahhiighaa. Ghoulia said with her confused look on her.

What a portal are you serious? Cleo asked the zombie girl. Aaahhaa. says Ghoulia. Well if it's a portal then who's coming through it? asked Clawdeen as the portal then turned sideways, then it floated up until it was 7 feet in the air. Now what is it doing? The Werewolf girl asked wondering what the portal is doing.

Then a sound came from the portal. Aaaaaa.

What is that sound? Draculaura asked. Aaaaaaaaaa. I think it's coming from the porta. Frankie said pointing at the portal. aaaaaaaAAAAAAAAAAAAAA. Then someone came out of the portal. AAAAAAAAAAAAAAAAHH.

THUD!

Then the person who came through the portal had landed with a loud thud, bringing up a big dust cloud where he landed, then the portal started to close.

ZZZZOOOOOOOOOOMMM!

POP!

And just like that, the portal is gone.

Well that happened. Said Frankie still looking at where the portal used to be. Hay ghouls look who ever came through the portal is now getting up. Draculaura said pointing at the dust cloud, that is hiding who ever landed there.

Oh man, that hurts, what even happened. Said the person in the dust cloud. It's a boy. Said Cleo in surprise. cough cough cough, man where did I land at, better yet, where am I? He asked himself.

Frankie then decided to ask him if he is okay, Hay are you okay? Ummm who is there? The boy asked. I'm Frankie and these are my friends, who are you?

Ummm you don't recognize the voice of the one and only Ben Tennyson? Ben asked from the dust cloud.

Frankie and the rest of the group of ghouls looked at each other confused on who Ben Tennyson is. Ummm sorry but we never heard of you before. said draculaura.

Wait what? Said ben confused, as he walks out of the dust cloud causing the ghouls to gasp in shock. What do you mean you have never heard of my name Be...fore, is all Ben could say, as he looks at the group of girls.

Both Ben and the Ghouls look at one another, ben looking at the Ghouls, as the ghouls look at Ben, the entire area was silent, but then the silence was broken.

What the? Ben and the Ghouls say at once.

End of Prologue

(Author's notes) And that's the Prologue of this story everyone, man it took me forever to make and finish this prologue, I thought it would take a lot longer but I've finally finished, I thought at first I was going to make a part 2 prologue, but I decided against it.

At first I thought of using Dr. Animo as the ben 10 villain, but then the Vreedle brothers came to mind, so I used those 2 instead of the Dr. Animo, but don't worry he'll be in the story at some point.

At first I didn't know how to start the story, I thought of having him end up in the Monster high universe where he either had to disguise himself as one of his alien form, that or have them just go to school the Normie, but having him meet the Ghoul squad like how I had him meet them in the story was better.

You might be wondering who is this mystery person who left Frankie the letters you may have some theories you may have an idea but I won't say until I'm ready to tell you in the story until then you're going to have to be patient that or wait to see if you're right or not on who wrote the letters.

Next is Chapter 1, ben meet's the Ghoul squad, ben finds out that he's not in his universe, ben goes to Monster High, ben becomes friends with Lagoona.

Next chapter, Chapter 1 - A new world.
