Ben was waking up early one morning as he yawned and looked to the utimatrix, his replacement for his destroyed omnitrix. He thought about his final battle against Vilgax it happened a month about but it was still fresh in his mind.

He rubbed his eyes and got up and dressed as he headed down stairs to see his dad on the phone.

Carl said, "Thanks man." He then looked to his son Ben. And said "Well we have big news for you Ben."

Ben looked confused, "And that is?" Carl then said, "I just got off the phone with an adoption agency, you're getting a new little sister."

Ben looked stunned for a moment as he grabbed the utimatrix, "dad I know adoption is a wonderful thing but you want to bring a kid in to this family, where someone is a literal super hero? "

Carl then patted his son's shoulder, "You saying a super hero wont' be a good big brother."

Meanwhile on a plan was a little girl with orangish brown hair and brown eyes, dressed in a blue sweater, blue skirt, with white kneesocks and brown shoes.

This girls name was Chiyo Mihama, well know it would be Chiyo Tennyson. She looked sad.

Chiyo's point of view.

My name is Chiyo, I'm Ten years old who is so smart she's in highschool, and last month my parents went away one a business trip and never came back. Now I'm going adopted overseas having to leave my home, at lets the air Port is leading me bring Mr. Tadakichi with me.

Before long the plan landed and I got up to the cargo place to pick up Mr. Tadakichi, he barked happily when I let him out of the pet holder and licked my face.

And I hugged my dog, who is so much bigger than me. I then walked out to the airport to see a family holding a welcome Chiyo sign.

I walked with Mr. Tadakichi to them I wonder how this will turn out? I mean I'm in a new country? With a new family? And what looks like a big brother? What kind of adventures await me in America?

I mean I hear they have super heroes and super villains but that can't be true right?

Return to third person point of view.

Ben got down and smiled, "Hi I'm Ben your new big brother." Ben then held out his hand and Chiyo shock it.

A few weeks later.

Ben was at Mr. Smoothie talking to Kevin and Gwen as he said, "I mean it's been a quite week with no problems but I'm more worried about no matter what I try I can't seem to bond with Chiyo. I mean I save the day easy but I can't even big brother."

Kevin then took a sip of a smoothie and said, "Ok Ben stop for a moment and put yourself in her shoes. You're in what is basically a whole new world, in a new family, having left almost everything."

Gwen blinked as she spat out some Smoothie, "that was well thought out for you?" Kevin shrugged and said, "hay I was in plumber juve. They only let you read educational books to try and make you better yourself."

Ben then laughed, "they made you read That had to be horrible."

Kevin then pointed at him and said, "watch it!"

Gwen then said, "Now I think Kevin is making a point!' ben then raised his eye brow as she said, "I know but it's true. Think back to when we were Ten, we didn't get along. Then one camping trip later we were best of friends."

Ben then said, "one camping trip and a summer of super villains later you mean."

Kevin then said, "But she's right it couldn't hurt."

Ben smiled, "Well I'll try to arrange it then."

Later that Weekend. Chiyo, her dog. Ben, Gwen and Kevin were setting up camp.

Kevin then said, "Remind me how I got roped into this?" Gwen then said, "because I asked you too."

In a moment Ben heard barking followed by a "Mr. Tadakichi come back!" they then turned to see Chiyo gone!

Ben panicked and turned to dial and said, "Screw secrete identity! Responsibly wins." He then slammed it down on Wildmutt and ran off like a mad man into the woods.

Kevin then said, "Can't you track her?"

Gwen shrugged, "we got nothing of her's here! But we have something of Bens?" She then pulled out a sumo slammers card, "A little something he brings with him for good luck."

Kevin looked at it, "really I keep the same card in my dashboard for good luck too."

Gwen held the bridge of her nose as she said, "focus kevin Ben will surely find Chiyo and we can now find Ben."

A moment later something fell out of the sky making the ground shake. Kevin then said, "A strange crash on a camping trip, and your cousin is running around as Wildmutt, I bet this brings backs some memories."

In the forest Wildmutt was snipping around he picked up Chiyo and Mr. Tadakichi easily but now he was picking up another scent, Sunder's!

Wildmutt roared as he funded them in the same direction, making him turn the dial on his chest transforming into ultimate Wildmutt who yelled out, "ULTIMATE WILDMUTT!"

He then raced off like a wild animal as he said, "Don't worry Chiyo big brother is coming."

Meanwhile farther in the woods Chiyo had caught Mr. Tadakichi who was barking as she said, "why did you run off," She then looked around to see she was lost and she screamed "AAAA!"

At that moment she heard a voice said, "Shut that dumb animal up!" She then turned to see someone on a glider thing.

he had grey skin white hair a double blade energy Axe and was dressed in red gloves, a red muscle shirt trim, black pants red boards with a black loincloth with a red belt holding it up he held the axe tight as Chiyo's eyes teared up.

Chiyo cried as she said, "eep?" this thing clearly was not human but her dog was barking at him and in a moment he raised the axe, "I guess I'll have to shut it up!" he and he was about to swing it down.

But out of nowhere there was a blinding Red Flash as Ben in human form jumped in grabbing Both Chiyo and her dog and bringing them with him as he slid out of the Axe's path.

The Axe hit the ground as Ben Got up and forced Chiyo behind him, "you leave my little sister Alone Sunder!"

Sunder smirked as he feared his Axe, "Ben10 has a little sister you learn something new every day." He then altered the button half of his axe's handle into a rope and swung the weapon like a fail at their way.

Chiyo's point of view.

I chased Mr. Tadakichi out here, meet something not human who wants to kill me than my new big brother rushed out like a hero and saved us. And he knows its name? What's going on?

I then Noticed big brother messing with that thing he wears on his arm, what is it anyway I saw little holograms of things appear on it, and I knew them form news reports, those are those Alien super heroes.

In a Flash I heard him say, "Chiyo I'm sorry I couldn't keep you out of this!" in a moment he slammed it down as the Fail like axe came our way.

In a bright Green flashed I watched as my big brother turned into a four-armed Monkey, grabbed me and Mr. Tadakichi and jumped pulled us out of the Axe's way by spinning a web form his tail, and using the tail to pull on it as a rope, to get us to the top of a tree.

He then said, "Spider-monkey." My eyes widened as my jaw dropped. As I put it together the thing on his wrist turns him into things, so he's all the super heroes! I have a super hero for a big brother."

Return to third person point of view.

Ben quickly used web to make sure Chiyo and her dog would stay safe in the tree top as he said, "I'll explain later little sister right now I have to do hero things."

Spider-monkey then jumped down and said, "Hay Sunder! I've Gotten some new tricks lately!" He then turned the dial making four points pop out transforming him into ultimate Spider-monkey.

Sunder looked stunned as ben said, "Ultimate Spider-money!" the ultimate Alien unhooked his jaw and fired off a massive Webbing bullet.

Sunder jumped from his Glider so that only it got webbed to a tree, he then whiched his fail back to an axe and tried to Swing it down at ben.

One of Ultimate Spider-monkey's spider-legs blocked the Axe and held it back as Ben Punched Sunder in the Stomach so hard he let it go as he said, "you can mess with me all you want but you leave Chiyo alone!"

In a moment Sunder found himself stuck in a web cocoon as the ultimate picked him up and throw him across the forest saying, "I don't care where you go you just can't stay here!"

Once he was out of view the utimatrix timed out returning Ben too normal and he looked to see a stunned Chiyo who's jaw was dropped.

Chiyo blinked and asked, "how?"

Ben then climbed up and untied them before heling her and her Dog down as he said, "Well it all started when I was Ten, when this thing called the omnitrix fell out of the sky."

At that moment Kevin and Gwen arrived.

Later on they were walking to the crash site as Ben finished telling his origin story, "and that's my origin Story Chiyo.

Chiyo's jaw was dropped, "I have a super hero for a big brother!"

Gwen then looked to kevin, "ok now why are we heading to a crash site instead of Getting Chiyo to safety?"

Kevin then said, "simple Gwen. One if Sunder wants something here we can't let him have it. Two Chiyo is Ten, you faced super villains at Ten without super powers and look how you turned out."

Ben then added "three if Chiyo isn't with us she might end up alone with Sunder again." Chiyo shivered

They then came to a white pod of some kind as Ben said, "ok we were on a camping trip, I was wildmutt and we found an alien tech pod that fell from the sky, it's official I'm Ten again."

Gwen then walked over to the pod and touched it giving her a shock as she jumped back, "ouch!"

The pod then opened to reveal a blond haired young human lady with green mist being let out by the pod with covered her.

Kevin and Ben quickly turned around blushing. Chiyo blinked and asked, "Why is a lady with no cloths in the space pod?"

Ben removed his jacket, "good question but for now Gwen please hand her my jacket to cover with."

Later at the camp site the Woman adjusted her hair and said, "once more all I know is my name is Eunice. I don't know why I was in that pod."

Chiyo was blinking as she ask, "then do you know what happened to your clothes?"

Eunice shrugged again as a happily little bird land on her shoulder. She smiled and petted the bird while smiling.

Kevin then said, "This is weird even for us." He then noticed something on Gwen's hand and said, "wait what's that."

Gwen looked at her hand the one she touched the pod with there was a small burn, "it looks like a small burn."

Kevin rubbed his chin as he said, "I heard old DNA scanners give shocks and burns Wait I have an idea, just hold up here I'm going to go head back to my car to get something. No one move!"

Ben then said, "Like we could?"

Kevin then ran off and as soon as he did Sunder now covered in mud walked up holding a laser gun and he opened fire, Making Chiyo scream.

But Gwen protected him with a wall of Mana. Ben then quickly transformed into Swampfire as he said, "Swampfire!"

Ben forced Chiyo behind him as she held her nose and said, "so stinky!"

Sunder growled as he turned a switch on his laser gun and said, "I want the Unitrix!" he then fired the gun this time it's blast was stronger.

So strong it shattered the Mana wall and send Gwen back flying making Eunice run away screaming as Swampfire throw fireballs at Sunder. "the uni-what?"

Sunder then fired on Swampfire, who made the trees and pants of the forest reshape themselves to block the fire while Roots covered him and Chiyo and pulled them underground.

Ben and Chiyo then reappeared behind Sunder where Ben Punched him in the back of the head making him drop his gun.

A tree then moved and grabbed the gun taking it out of Sunder's reach.

Sunder roared, "the proto-type for the thing on your wrist boy! A DNA container able to take a sample of one species and become a member of it! Now it's taken human form I'll have to erase its data to sell it."

Swampfire's eyes widened as did Chiyo, "Wait the Girls, is an omnitrix that can move around on it's own? Wait but how she doesn't look like Gwen, and Gwen is an anodite like grandma."

Sunder then said, "Anodites are pure energy they have no DNA! Your cousin's body is human as is the unitrix! And finally the DNA is randomized to make an original life form instead of a clone!" he then charged to try and punch Swampfire.

But Swampfire moved his hand making a tree grab Sunder and hold him still, "well this got strange!" he then hit the dial and morphed into big Chill who said his name before going ultimate and saying "Ultimate Big chill!"

The ultimate alien then saw Sunder break free of the tree now that he couldn't control plant life. So Ben breathed out his ice fire freezing him in a block of ice from the neck down.

Sunder shivered, "It's so cold it burns!"

The utimatrix then timed out returning Ben too normal. Chiyo's eyes where once more wide, but they were sparkling.

At that moment kevin came up holding a broken arm with Eunice as he said, "I was coming back with my DNA scanner when she touched a bear made it fall asleep then broke my arm with super strength."

Eunice then said, "you scared me!"

Azmuth then teleported in as he said, "That's because while she does have a form now, she still has a DNA scanner which she can use to copy another specie DNA for about ten minutes till the unitrix self repair systems restore the DNA to base."

Mr. Tadakichi was about to bite Azmuth but the old Galvan hit the dog on the head with his Cane as he said, "Bad dog!" the dog then fell down and got up and walked away.

Chiyo blinked, "You're so tiny and cute!" her eyes sparkled as Gwen got up and said, "That's Azmuth the creator of the omnitrix."

Azmuth nodded, "I'm the smartest being in three arguably five galaxies, Now I would love to play games here but I don't have time to waste at my age." He then spotted Chiyo, "you must be Chiyo your grandpa me his son adopted a daughter, but I'm here about Eunice here!"

Eunice tried to run but Kevin held her back, "You won't put me back in storage."

Azmuth blinked, "Now why would I do that? You're not a piece of tech anymore your alive being, that would be wrong so Eunice clam down!"

Eunice then took a deep breath, "Sorry,... dad?" everyone blinked in shock but Azmuth said, "Well I did make you so I guess I am kind of your father, but you can't stay on earth people will be coming after you!"

Azmuth held his chin." I got it, you see my prototype omnitrix and Ben's current bootleg version's storage needs are so large I had to make a planet to house all the DNA samples. I called it primus how about you come with me to help me run it?"

Eunice smiled, "that sounds fun!' Azmuth smiled as he hopped on to her shoulder and in a moment he said, "Be seeing you when I think you're ready for the finished model Ben!" in a moment he and Eunice teleported away.

Later on that night after deciding to all go home.

Ben was in his bed when he heard a knock on the door and spotted Chiyo in the door way.

Chiyo was crying "big brother I had a nightmare can I sleep with you?"

Ben then rubbed his eyes, "you know most kids run to their mom and dad when they have bad dreams." Chiyo then said, "Most kids don't have a super hero for a big brother."

Ben smiled and said, "Ok" Chiyo then hopped in bed and asked, "big brother can you tell me more about that road trip were you where ten?"

Ben then smiled as he told the story, of when he was ten.

To be continued.
