I do not own anything in this fanfic.

For reader information.

1. This crossover fanfic took a place when Alex, Clover and Sam are studying in Beverly Hill High ( around second season of their show, roughly)

2. Ben in this fanfic will use Ben in Hero united

3. His omnitrix did not be the same. It does not transform him to be the alien but I give that alien power to him just like Biomnitrix but he cannot mix his alien power yet.

4. I will use every Ben's alien in this fanfic except ultimate form.

I hope you are going to enjoy this fanfic.

Thank you

Ch 1

***Under the basement of government agency house in California***

Sam, Alex and Clover are captured by theirs' enemy, the Computer Home Analyzer and Defender aka CHAD. He came back from IT hell to revenge these girls. He set up this trap by sent a false emergency signal from this house which under WOOHP protection. Jerry received it and sent these girls to look and see what is happening. Those three girls are binding with the torture chair. CHAD is going to torture as a payment for what they did with him.

"How could you alive?" Sam yelled "We thought we toasted you with the house already."

He laughed robotically and said "Oh poor Sam. Since you all going to die, I will tell you how. You see, I have a program name Back up."

"What!" They yelled and stunned.

"That is right" He exclaimed "I was back up myself in somewhere that was totally safe from any of you can detect. I mean how could I be the Computer Home Analyzer and Defender without a backup plan, right? Ha ha ha."

"Where have you been for all this time?" Alex asked

"Oh Alex, you really want to know" He mocked "Why don't you girls try to guess? We have a lot of time. Besides there is no way you girls can escape form here because I destroyed your equipment already. I am talking with you, Clover."

Clover that was doing something secretly, she startled after she heard him. He is right. Theirs' equipment are broken even WOOHP's powder. They cannot contact Jerry or call for a reinforcement. They are on their own.

"We needed to buy time to find an escape" They thought and look each other.

"Alright, let's play twenty questions game" Sam said "But how could you broke our equipment?"

"Yea" Alex yelled "This is not fair for us."

"That's right" Clover supported "To be fair, you should give us a chance to fight back."

He laughed and said "No way girls. I do not want to fail like last time. Come one, let's play a game with me and maybe I will let you go and have a chance to fight for your life."

"Fine" They exclaimed

"Good" He yelled and played a game show theme "Now, let start with our smart girl. Sam what will you guess for my secret hidden place?"

She was thinking before she said "Can I ask first?"

"You got that right" He replied "Your first question is?"

"Is it on the earth?" She asked

He muttered and said "Yes. My hidden place was on the earth. Now, it is your turn, Alex."

"Ummmm" She exclaimed

"Relax" He said "Take your time to think. Make it worth for your question."

"Is it in the USA?" She asked

"Yea" He replied "What are you going to ask for the next question, Clover?"

"Oh I am not good in this kind of game" She cried "I am a beautiful girl. The question is belonged to the NERD."

"Hey, what do you mean by that?" Sam and Alex yelled.

"Sorry girls but I said the truth" She replied "I mean I am the beautiful girl among us, right CHAD?"

"Ummm, I do not think I can answer your question" He said "Let get back to the game, shall we?"

"No" Sam and Alex argued "We are not going to play your game until we settle the problem with her."

"Wow" He exclaimed "I should leave you girls alone. Call me when you done."

He finished and moved his interface away through the tunnel. He is really left them alone. They were arguing about women stuff for a while. They argued each other until they are sure CHAD is gone away.

"Good job, Clover" Sam said "Your plan to make him leave the room, it is totally good."

"Yea" Alex exclaimed "Now we can find a way to escape from here"

"Girls", are you sure he does not have CCTV to watch us? Clover asked

"No, trust me" Sam said "I read a report about this house before we are arrived. They said they have not any CCTV or bug in the basement. Therefore, we are totally clear."

"Give me a minute" Alex said "I think I can break this binding. If I just… got it"

She managed to break her binding. She is freely to move and help her friends. Finally, our girls are freed from those crazy chairs but there is a problem. They are still sticking in the basement. The only exit is the twenty millimeter titanium door that is locked by CHAD.

"Sam, can you hack this door?" Clover asked

"I cannot" She replied "Without our spy equipment; it is too dangerous to hack it without CHAD notices us."

"Great. This mean we are sticking here with a crazy program computer who has a grudge against us. Without spy equipment, food and my make-up how could I live here" Clover complained "I am younger too die alone in here. There are so many things I need to do such as date with handsome guy, eat dinner with handsome guy and see a movie with handsome guy."

Sam and Alex shook their head and sighed after they just heard what Clover talked about but there is a truth in Clover's complained. It is the dead end if they cannot escape from here. Even though, Jerry might notice and send a reinforcement to help them but it might be too late.

"Relax Girls" Sam said "We were faced with so many dangerous situation and we passed it if we worked together. There is also no different in this time. Let's look around the room and maybe we can find something useful."

"Okay" Alex and Clover replied

They were searching and opening every boxes and desk drawer they found in the basement until they gave up because there is nothing left to search. They are sitting in the middle of the room by placed their back against each other.

"What should we do now, Sam?" Clover asked desperately

"I do not know" She replied hopelessly "This is my first time to face with a situation like this."

"Hey, if we die, at least we are together" Alex chuckled "The only way we can survive from this situation; it must be a miracle, right?"

They were going to embrace and comfort each other but something happen up there. They heard explosions from up there. It was louder and stronger enough to feel a vibration. It like the whole building is going to collapse. They looked at each other and thought, is CHAD did this? Suddenly, CHAD was coming out of his tunnel whit the angry face. Our girls do not know what is happening but CHAD did not make explosions definitely.

He said "Huh, I am so surprise in your organization. They always have a little secret. From my information, there is no male spy agent until now. I guess I was wrong but do not worry. I will deal with him and come back to finish you all later. Now, I hoped you are going to enjoy watching me beat the crap out of your friend."

He left the room without listen to them and then a monitor pop up from the wall and something is showing up. It is a live broadcasting from the CCTV around the fence. They looked closer and saw a single male in black leather jacket with black leather pant. He is also wearing cool motorcycle helmet.

"Who is he?" Alex asked

"I do not know but he look so coooool and stylist" Clover replied "Look, he is wearing a black leather gloves and awesome boots. I never saw those clothes until now."

"Clover, this is not a time for this stuff" Sam yelled "He could be another WOOHP's enemy. We do not know his attention."

Then, they saw ten security androids are surrounding him. Normally, people will scare and panic but not for this man. He looked around and waved his hand like there is nothing there.

"He is going to die." Sam said

Even though they cannot hear any sound through CCTV but they saw he was yelling something and was a person who charged those android instead. His first strike landed at the android that was standing in front of him. His right fist punched through it metal body like he punched cake. The metals are scatter behind it like broken glass as the android out of combat in his arm.

"What the?" Ale yelled "Did you see that? He just…"

"We saw that" Sam replied

Other androids found their surrounding formation was destroyed. They changed their plan and scrimmage him like rugby. That man grabbed the android corpse in his arm and threw it away like he tossed a ball. It flew away and hit with one of them but it could not stopped the rest of them.

They threw fists and feet at him but he managed to dodge them and escape from their surrounding formation again. He ran away to make some distance from them. They followed him but they were not together.

He saw it as a chance to strike back. He turned back and faced with the closet android. It threw a fist at his face but he dodged it by spinning around. He used the momentum to increase his karate chop strength.

"Slaaaaaaash" He separated the robot head from the body. Robot head was flying in the air while he grabbed the body and swung it like a pendulum. Other robots are standing still because CHAD does not give them the order or command. He is confusing because he cannot analyze and evaluate this guy fighting skill and potential.

"Who the hell is he?" He thought "This is not WOOHP style."

In the moment robot head fall down to his line of sight, he hit it with the robot body like he is playing a baseball. It flied like a bullet. It hit with one of them. That robot fall down to the ground like a bird who got short. CHAD could not believe in what he just saw. He lost two security android in a few second. They cannot even make him scratch.

"Alright, let see if I am increase their power" He exclaimed

Suddenly, those androids were shaking and screaming like they are breaking apart. They are changing or to be more accurate, they are casting off. They removed their hands and replaced it with sharpen swords.

This time, the mysterious man is stunned and surprised in what he just saw. He looked around like he is finding something until he found the CCTV that is broadcasting him. He looked at it like he knew who are watching him. Suddenly, he did something that was so rude. He showed his middle finger to CHAD.

"YOU filthy and low life human" He yelled "All of you kill him now."

Android eyes turned red as they received their order. They jumped at him together. Our spies thought he was going to dodge them but he did not. Instead, he stands there and waits for it. He did not show any sigh of scare or panic. Their swords are going to stab him like they stab dead meat if he does not do something.

"Stab stab stab stab stab stab stab stab" What our girls and CHAD is seeing, the mysterious man is stabbed by those android's swords. Our girls cannot believe and do not understand why he did not dodge while CHAD is enjoying and satisfying.

He laughed and said "This is your payment for disrespecting me. Now, I can finish those girls."

Even though our girls did not know he but they are crying because they saw person got killed in front of their eyes. Alex and Clover were embracing and comforting each other while Sam was the only one who did not leave her sight from the screen

She noticed something and said "Wait girls. I do not think he is done. Look."

Alex and Clover looked at her pointed and saw, something in the middle of those androids is moving. They are surprised and stunned because the mysterious man is not dead. He is preparing to do something. He raised his both hand and smashed at the middle of the circle.

"BOOOOM" He just destroyed those androids with a single strike but there is something else coming up. He is created a mini shockwave which is shaking the whole area around there especially CHAD sensitive and fragile system.

"SHITTTTTT" He yelled while his monitor was blinking like a broken TV. When he back to normal, the mysterious man is gone. He cannot find him at any CCTV he have. This is so annoying and making him mad.

"FUCK YOU" He exclaimed "I do not have a time to play with you anymore. I am going to kill those girls."

Before he left, he saw the mysterious man again at CCTV number 13. The mysterious man is looking through CCTV like he knew CHAD was watching him.

"What the hell are you doing here?" CHAD said and saw the mysterious man touched the CCTV with his hand and then something that is impossible happening with CHAD. He felt electric shock though whole of his system. Someone is firing his electronic system alive. He is screaming with abnormal language. No one could understand him but it must be so painful from his screaming volume.

"Y…o….u….Araaaaaaaaaagh" That was the last thing we heard before he is gone forever.

Our girls do not know what happen up there because the monitor is also gone. They also heard CHAD's voice through the tunnel. They looked at each other and thought, they are going to see and meet the mysterious man but can he pass through the titanium door?

"I am scare" Clover said

"Me too" Alex exclaimed

"Relax girls, we are going to knock him with our teamwork" Sam encouraged them.

"BAM BAM BAM BAM" The titanium door is punched by the mysterious man. Our girls cannot believe in what they see. They saw dents on the door every time he hit it and it is getting bigger and bigger.

"POOOOOW" Finally, he made a hole on the titanium door with his fists. Some part of it flew away and hit with the wall and stuck on it like a wall paper. Our girls are surprised and stunned in his strength.

"Here he comes" Sam yelled as they are prepared to fight for their life.

They saw his hands came through the hole. He grabbed and started tearing it like a paper.

"EEEEEEEEEEK" He was tearing apart and made a bigger hole that was enough for him to walk through it. His right foot is stepped through the door and followed by his body and left foot. Finally, he is standing inside the basement room with our girls. There is nothing blocking him from them except air element.

"We are not scaring you" Sam yelled "If you are going to capture or kill us, it is not easy I can guarantee, right girls?"

"Yea" Alex supported "We are going to break every bone in your … body."

"That's right" Clover joined "We will beat the crap out of you, do you hear me?"

The mysterious man is looked around and pointed at him with confuse. He laughed at them because he knew what is going on. Finally, our girls hear his real voice. It is a normal teenager voice.

The mysterious man said "Take it easy, I am came here to help you and this is how you treat your lifesaver? You are so mean."

"Lifesaver?" They yelled

"Yea" He replied "Let get out of the here first, shall we?"

Our girls did not reply because they are confusing in the situation. The mysterious man sighed and left the room without get closer to them. They looked each other with surprise.

"What should we do?" Clover asked

"Let's get out of the here and figure it out later" Sam suggested "When we are outside, all of us must be on guard."

"Agreed" Alex and Clover replied

When they were outside, they found nothing except scrap everywhere. They did not see him until they heard someone whistle from the front gate way. They saw he is riding the modified Dodge Tomahawk. He painted a whole bike with pure gloss black shadow with the green LED light. It like this bike came from TRON movie. When he accelerated the engine, the green LED light glowing bright and brighter.

"Who are you?" Sam asked

"We will meet again" He said and left the house with his superbike. He passed through WOOHP helicopters and left the area without anyone chasing him. The WOOHP's support teams came out of the helicopters and did their job. Our spies are getting on their helicopter to get back to their house.

On the way back, they were talking about what happened today especially about the mysterious man who saved their life. Who is he or they should asked what he is? They are so sure that he was stabbed by those androids. How could he be alive after he got stabbed? What about his strength? There are so many questions in their mind but they do not know who they should ask with.

***Few days later***

***At Beverly Hill High***

Luckily, their last mission was on Friday. Our spies had a chance to take a rest and heal their wound but that was not a point. For a two whole days, they were talking about that mysterious man. They even used WOOHP satellite to track him but they found nothing. It's like he is a ghost.

"Hey, what is our first class for today" Alex asked while she searched her locker for a book.

"Let me check my class schedule first" Sam said and opened her smartphone "It is Miss Colligan's history class at room 1215. We should get going or we are going to be late. She is so punctuality."

"Miss Colligan!" Clover yelled "I hate her so much. I wished, we have a mission right now."

Unfortunately, nothing happen as she wanted. She looked sad and grabbed the history book from her locker and left to the class but they cannot go yet. They heard a person who they hate so much especially Clover. She hates her so much, more than any teacher in Beverly Hill High. That is right. We are talking about Mandy.

She is talking and laughing with her friends, Caitlin and Dominique. Our girls knew what is going to happen. They wanted to avoid the argument especially on the Monday morning but here they come.

"My my Clover, is that you?" Mandy mocked

"Hey, Mandy" Clover replied "I am right here. Are you blind?"

"Silly, I am not blind" She said "I thought you were hillbilly because your fashion is so out, right girls?"

"Yea" Caitlin and Dominique supported

"What?" Clover yelled "This is the newest fashion. It came out yesterday. How could it out?"

"Duah" Mandy mocked "The newest one is here. It came out today morning."

She showed her the newest pink handbag which looks exactly the same as Clover's handbag. The only different they noticed is the accessory on the bag.

"Let get out of the here girls or you will get a hillbilly disease from them" Mandy mocked

"What!" our girls objected and they were going to kill her but something interrupted them

People are talking and looking at someone on the hallway. It managed to stop their cat fight because they wanted to know what they are looking at but there is too crowded. They tried to break through human wall but they could not. Therefore, Sam asked people around there.

She asked "Hey, what is going on here?"

"Do not you know?" Female student replied "Today, we got a transfer student from Bellwood. The best part, he is a teenage boy who looks so handsome and cool. He also has his own superbike. I saw it by myself."

"Really" Clover and Mandy yelled unison.

Without a thought, those two girls used an emergency strength to penetrate the human wall and moved to the frontline and see how this new student cool is. The rest also followed them as they wanted to see him too. It like they are in the grinning machine.

People wave is crushing them one by one. Caitlin and Dominique were given up in a few second after they were in the human wall. Finally, the rest of them managed to stand at the frontline as they wanted. They are stunned after they saw him.

The teenage boy is wearing blue jean and green jacket with white stripe over black shirt. He made side part hair style. He is carrying blue rucksack and bright green motorcycle helmet. He is walking through people like a normal even though people are gossiping about him and his cloth especially "Number 10" on his left chest. Does it have any meaning to put that number on his cloth?

"He is so cooooooool" They exclaimed as he heard them.

He looked at them before he smiled and winkle his eye to them. They are startled and stunned like a stone. They are charmed by his personality and mystery aurora especially Sam. She felt like she saw him before but she did not know where. In the end, people are fading away when the new student is in the principal room as our girls realized something

"God damn it" Sam yelled "We are too late. We need to run, now."

"Oh he is so handsome" Clover exclaimed "I am going to talk to him today and no one can stop me."

"Except I did it first" Mandy argued "He will be my next boyfriend without doubt."

"No, I saw him first" Clover yelled

"You snooze you lose" Mandy replied and ran away with her friend

Clover was going to say something back but Alex and Sam stopped and pulled her away. They are dragging her to the class. During the way, Clover was the person who talking about him all the time. Alex and Sam also wanted to say about him but there is no time for women talk.

When they are at the class room, they found Miss Colligan was not here yet. They did not know why but it make them escaped her complain hell. They took their usual seat which located at the front. Sam and Ale grabbed the book and prepared to study while Clover was doing her makeup.

After five minute, Miss Colligan came into the class and told her students about why she late. She said the principal called her to pick up the new transfer student. Students are surprised and excited to meet this new student especially our girls.

"Girls, did you hear that?" Clover excited "This is my destiny to meet him here, right? Oh this is so romantic like a princess story."

"We heard it" Alex said "Take it easy, Clover. If you expected him too much, you will sad when you disappoint in him especially a new guy who just transferred here"

"No way" She argued "There is no way I am going to disappoint in him except…"

"What do you think, Sam?" Alex asked Sam who was thinking something "Sammy?"

"What?" She startled because Alex poked her waist

"I was talking with you" Alex said "Are you feeling okay?"

"Sorry, I was thinking something" She replied

"Alright, everyone quite" Miss Colligan yelled "Please come in, Mr.…Pennyson"

The door opened as the new student walked into the room. He stopped when he was at the teacher desk. He stood properly and smiled to everyone in the room before he introduced himself.

He said "Good morning everyone. My name is Benjamin Tennyson but you can called me, BEN."
