Chapter 1:

At the Museum, everything seemed peaceful. Everyone was looking at a rare alien artifact called "The Annihilargh." Nobody knows where it came from. Then there was a crash.

"Ladies and Gentlemen," says the crasher, "allow me to introduce myself. I am Silverclaw! Don't be alarmed, I'm just here to borrow some of the exibits. Now, which shall I steal first?"

"How'bout none."

"Ben 10!"

"Didn't you get the memo, it's 10,000 now."

Ben then turns to Swampfire. "And to think, Gwen wanted me to call this guy Fireweed."

"Well, don't forget why they call me Silverclaw!"

Silverclaw tries to scratch at Ben, but Swampfire can heal. Ben then uses his power over plants and has a plant grab Silverclaw. Silverclaw then scratches his way out of it.

"Okay, should've thought of that."

"En garde!"

Swampfire then throws a fire ball and Silverclaw dodges. Silverclaw then tries to strike again, but Swampfire can still heal.

"We seem to be at a stalemate..."

Swampfire knocks Silverclaw out.

"You talk to much." Swampfire then walks away and the police arrive, taking Silverclaw in.

. . .

We are now at a secret base called the Decagon. Headed by Director Gwen Tennyson. Since she is no longer the President, she has a new career and this is it. Also, the new President reassigns the former villains to work there, do to them creeping everyone out.

As Gwen walks, something pops up and scares her.

"Devlin, what did I say about using your amalgam form to scare me?"

"Can't I have some fun?"

"Not if this fun leads you to being grounded?"

"Come on, Mom."

Gwen's son, Devlin turns back to his human form.

"That's better."

"So, what you got Ken for his birthday," asks Devlin.

"What?"

"You know, Uncle Ben's son. About this tall..."

"I know who he is. And he was born on October 6 and today's..." Gwen checks the calendar. "Oh."

"Want to share the credit for what I got him?"

"I would appreciate that."

Then Max holograms in.

"We got another message from the Plumbers."

"Here we go again," says Gwen.

The hologram of Max is replaced with an image of a man who looks like a blue cat.

"This is Magister Rook Blonko of the Plumbers..."

"Dude, we know who you are by now," says Devlin.

"Right, has Ben Tennyson finally accepted our offer? We could really use..."

"Sorry Mr. Rook," says Gwen, "but he still says no."

"Oh, I understand. It was nice speaking with you again." Rook disappears.

Hex appears. "I couldn't help noticing a pattern. Ben never seems to speak for himself."

"Oh... well... he's too busy, so he asks me to..."

"Gwen, does Ben even know about Rook's offer," asks Max.

Gwen sighs. "He has no idea."

"Woah, way to set a good example," says Devlin, sarcastically.

"Look, we need Ben here," says Gwen.

"Or do you have trouble letting him go," asks Hex.

"That criminal organization, the Flame Keeper's Circle is still out there and we'll need Ben to help bring them down."

"We're getting another call," says Max.

"If it's Rook again, tell him Ben's dead."

"It's the new President."

"Then tell him I'm dead!"

Max is replaced with another image.

"This is President Billions. I have a request. It's my daughter, Bella. She's kind of..."

"Spoiled," asks Gwen.

"Yes."

"Just like someone I know."

"Anyway, I was hoping you could help her."

"Well, I'm not too fond of you, but I guess I could."

"Good, I'll teleport her to the Decagon."

Bella Billions has appeared and she's using her hair to text.

"I still can't believe Billy Billions and Frightwig got together," says Gwen.

"That's what everyone says about you and Kevin," says Hex.

"Fair point."

"I can't believe my parents are making me stay at this dump," says Bella, "do you guys even know what money is?"

"She's nice," says Devlin sarcastically.

Then enters Ken Tennyson, the son of Ben.

"What up, Sydney?"

Syndey says something in his bug language.

"Hey Smythe."

"Oh, Hello Kenneth. How was your history test?"

"Aced it."

"No surprise. I was your tutor."

"How's it goin' Zombozo?"

"Oh you know, still trying to clown around, but you know how the boss gets."

"No kiddin'." Ken gets to Gwen and the others and Bella sees him. "Who's the new girl?"

"Hi... me am... someone... no remember... mind broken..."

"This is Bella," says Max, "Billy and Frightwig's daughter."

"Oh, so you got your Mom's hair powers," asks Ken.

Bella's hair then moves around do to her nervousness. "I gotta go!" Bella runs off.

"That was odd," says Ken.

. . .

Bella finds herself in a room. "Wait, where am I?"

"This is Ken's room," says Devlin.

"AAGGHH! I'm in Ken's room?" Bella looks around. "He has alot of old stuff."

"His Mom's Native American. He also has a collection of superhero memorabillia."

"Wow. My grandparents were upset when my Dad decided to quit the supervillain game," says Bella.

"Yeah, like my Dad, your Parents also tried to destroy Ken's Dad. Things are weird here. Now, let's go before Ken questions why we're in his room."

They walk out.

. . .

"Happy Birthday, Ken," everyone shouts.

"Check out what my Mom and me got you," says Devlin.

The gift's a hoverboard.

"Awesome," says Ken.

"Heather couldn't make it," says Hex, "but she did request that I make sure you had this."

It's a sentient stone creature. It jumps on Ken and starts licking him, making him laugh.

"Very good," says Ben as he enters, "it's gonna be hard to top a stone creature and a hoverboard. Let's see what I got, oh wait, I know." Ben hands his son a box.

"Wait, is this..." Ken opens it and it's a watch that looks like the Omnitrix.

"It's your own Omnitrix," says Ben.

"Does Azmuth know about this," asks Animo.

"... Sure."

. . .

"I sense a disturbance," says Azmuth, "like Ben has done something that will make me want to kill him."

. . .

Ken puts it on.

"You're limited to ten aliens. XLR8, Stinkfly, Wildvine, Slapback, Buzzshock, Spitter, Shellhead, Sandboxx, Snakepit, and Toepick."

"What," asks Ken, "I don't get any aliens like Atomix or Pulverizer? Can we at least replace Toepick with Grey Matter?"

"Yeah, you have a point. I don't think Polar's gotten over the trauma."

"He most certainly hasn't," says Solar, "it's going to be alright, brother. Just think about how inferior you are to me."

"Inferior?"

"Sometimes, there are perks to our sibling rivalry."

Then the alarm goes off.

"The Flame Keeper's Circle is back."

Ben turns to XLR8.

"He's been alot more ready ever since he got 10,000 aliens," says Maurice.

Ken turns to XLR8.

"Race ya," says Ken as he runs off.

"I remember when we feared the thought of there being two of them," says Animo.

Ben runs off.
