One month later.

Ben was at Mr. Smooth with Kevin, Gwen and Jessica.

As they all drank a smoothie Jessica then said, "Last day of summer hard to believe it!"

Ben nodded, "It seems like it's getting shorter and shorter as the years go by, I mean when we were Ten it last for years."

Kevin nodded as out of the corner of his eye he spotted Henry and Chiyo arguing.

Chiyo growled, "Now Ben would win! He beat kevin when they were kids!"

Henry growled, "No my big brother! He can do a lot more with his powers now!" Both kids growled.

Ben rolled his eyes, "Chiyo he's five be the more mature one and let it go."

Gwen rolled her eyes, "Ben telling someone else to be mature that's a new one!"

Kevin then pinched himself, "And it was real! That's the shocking apart, now come on Henry we have to leave Mom needs to take you shopping for a school uniform."

Henry then stuck his tongue out at Chiyo and left with Kevin.

Chiyo stuck her tongue out back and made a face.

Gwen then looked to Ben, "And what does this remind me of?"

Ben rolled his eyes, "ouch Gwen! Very ouch!" He then finished his Smoothie and burped before saying, sorry, the Cricket chocolate smoothie is messing with my stomach."

Jessica drank her and burped a bit too and said, "yet it's so good you can't stop drinking it!"

Gwen held the bridge of her nose and walked away and said, "you two are made for each other!"

Later on it was night time and in the Tennyson house Chiyo was just getting in to bed.

As soon as she closed her eyes she fell asleep and had a strange dream. In the Dream she was in her old school uniform running through Bellwood's empty streets calling out, "Big brother!"

She then spotted Ben standing on a building as ultimate Fourarms battling a man with redish skin a brown trench coat, the man had horns and was using spear as a weapon

Chiyo then spotted a large cage in the middle of the streets inside of it were five aliens.

One looked like a humanoid shellfish who spread water from his palms to try and brake out, "Help us!"

The next one looked like a turtle who was blowing a wind vortex, "He wants to eat our souls!"

The next alien looked like a large floating jelly fish and he said, "We don't want to die!"

The next one looked like a suit of armor with a red glow in it, "we thought the Tennysons were heroes!"

The last one looked like a bipedal yellow armored humanoid armadillo who had drills for hands, "Save us Ben10!"

In a Ben was before them he opened the cage and in moments the utimatrix turned him into them but his versions had the utimatrix symbol on his chest.

Chiyo blinked in confusion and went to grab Ben only for him to vanish and for her to find herself at Mr. Smoothie as she spotted Forever knights marching everything being destroyed behind them, "Death to all aliens!" they chanted.

Chiyo Screamed for Ben and found herself appearing on a beach. On the beach a large Squid like monster appeared and morphed into Vilgax as he appeared in the picture she had seen.

Chiyo was shaking and tearing up as she backed away, "No big brother said you were dead!"

Vilgax laughed as he drew a sword that gave him armor, "I will never die till I have Ben10's head on a platter!"

A Larger squid monster then flow down from the sky and eat Vilgax making its monster face morph into Vilgax's. "I am the ultimate terror! I will never rest! Ben10 will die along with his world!"

Chiyo was crying she spotted Ben as ultimate Swampfire throwing fire blasts at the Thing! "CHIYO RUN!"

Chiyo then cried and ran only to drip and fall and see the sword Vilgax picked up, she got up and touched it and looked back to see the Giant Vilgax monster about to eat her brother in human form!

Ben was being held by the tentacle so he couldn't reach the dial

Chiyo cried and grabbed the sword and slashed it saying, "Leave my big brother alone!"

Chiyo then closed her eyes crying only to open them and be back in japan.

At which point Osaka who was in an all-black dress that hide her feet, and had long sleeves, she adjusts a which hat on her head as she flew down from the sky on a broom stick.

Osaka then hopped off the broom and began petting a black kitten that magically appeared in her hands, "Hi Chiyo-Chun I'm a witch!"

Chiyo Blinked in confusion, "Say what?"

Osaka then smiled blankly and said, "Yeah. And this is my black kitten I name him crystal because it's cute!"

Chiyo looked confused, "Say what?"

Chiyo then once more Found herself in Bellwood where she spotted all the known ultimate circling around her for a moment before they vanished in a flash of Green to reveal Ben.

Chiyo smiled and raced to him only to walk through him and find herself in a field.

Chiyo land on her face and as she got up she spotted a man, who picked up the same sword as Vilgax he was donned in armor and was made young again. "Me and my knights will whip out the alien threat!"

Chiyo then cried, "You can't do that! They are all alien with thoughts and feelings! They live love and laugh! Sure some are bad, but the same thing applies to humans! The only monster I see is you!"

In a moment the Knight vanished along with everything around Chiyo!

Chiyo then walked around in darkness crying, "Mom? Dad? Big brother? Cousin Gwen? Anyone?" she was then crying when Ben Walked in and got down and hugged her, "It's ok Chiyo I'm here!"

Chiyo then hugged Ben as Ben smiled and opened a door that appeared out of nowhere and said, "Now come on let's go home."

Chiyo smiled and held her big brother's hand and walked through the door.

Chiyo then notice they were on a path with every form her big brother had ever turned in to around them smiling.

Ben smiled and said, 'Don't worry Chiyo big Changes and threats are coming but I'll keep you safe!"

Chiyo looked down and said, "But you always save me! I want to be able to help and be a part of the team! I don't want you to have to keep rushing in the way to keep me save big brother."

Ben smiled and said, "Chiyo you are part of the team, I was scared of the ultimates, and still am! But I use them because the drive to keep my little sister safe keeps pushing me forward. Plus, you were the hero once when you had the utimatrix."

Chiyo smiled a little and noticed a pink glow on a wrist. She was going to roll up her sleeve to see what it was but Ben stopped her and said, "You've already seen enough don't want to ruin that surprise. But come on Chiyo Time to go home and wake up!"

Chiyo then saw a door which had the Vreedle brothers standing guard in plumber's uniforms

Ben turned into Fourarms and picked her up and walked through the door Making Chiyo wake up in her bed.

Chiyo rubbed her eyes, "what a weird dream." She then yawned as she looked at the clock it was five minutes before her Alarm would go off.

She got out of bed and said, "well better get ready for school."

One month later.

Ben, Chiyo, Gwen Kevin, Jessica and Henry where at Ben's house.

Henry was playing with a toy version of his big brother's car.

When alert came on that showed a lot of Ben's transformation some of them turning into other aliens the end with video of one timing out in to ben and saying "All these alien heroes is one guy, Ben Tennyson!"

Ben's jaw dropped!

Chiyo screamed making her pig tails shake! "WHAT EVIL WOULD DO THIS?"

Kevin then said, "well Your totally busted man!"

Gwen then said, "This isn't how it's supposed to be!"

Ben then spotted a horde of reporters and Ben got up and looked dialed up Humungousaur, "I shall return!" he then walked outside transformed into Humungousaur and roared scaring them all away.

Jessica cracked her knuckles and said, "Well, Time to track down whoever did this and beat the crap out of them!"

Chiyo then grabbed a baseball bat and swung it saying, "LET ME AT THEM LET ME AT THEM!" She had a cartoonish made face complete with flaming eyes!

Kevin then said, "that is the most adorable rage I've ever seen!"

Henry then stuck his tongue out at the tv and said, "Badman!"

As a report came on bad mouthing Ben.

Jessica then turned off the Tv, "Gwen Kevin, call whoever you have to do track this crap! I'm going to go buy a metal bat!"

Meanwhile in Japan.

It was night when the alert came on, Sakaki was watching in her room, "Oh shit! Now Chiyo's in danger!"

In Kagura's house she heard the alert and said, "Well so much for being part of the secret keeping group!"

In Yomi's house her eyes twitched as she said, "What kind of monster would globally reveal a superheroes secret identity!? What kind of monster!?"

Tomo was in her house gasping so much she couldn't speak she was to shocked at the turn of events.

In Osaka's house she had on her blank shocked face and said, "oh my gwad! Ben's on tv!" she was clearly not smart enough to understand what this all really meant.

In Yukari and Nyamo's house.

The two where in bed holding each other under the covers as they watched it.

Yukari's eye twitched, "Now this happens! Great! As if having to look out for Aliens and Demons wasn't bad enough now we have to worry about revenge want super villains."

Nyamo was panting in panic and said, "How can you be so clam?"

Yukari then pulled her into a kiss and said, "because I have you in my arms that's how! Now Dear Calm down! Chiyo will be fine! Name one thing that can beat Ben?"

Nyamo then calmed down as Yukari turned off the tv, "Now let's return to snuggling I think this is a night were closeness is need!"

To be continued.
