The Warners stepped out in front of a red curtain. "The following chapter you're about to read has some scary content," Yakko said.

"By internet standards," Dot added.

"Right by internet standards, the following chapter you're about to read will have spoilers." Yakko looked around for the envelope. "Hey baby bro, where's the envelope."

Wakko belched out the envelope. It landed in Yakkos's hand. "There you go."

"Thanks," Yakko said. "The following chapter will have spoilers for Monsters Inc. and Monsters at Work."

"You know, for a crossover between a Warner Bros and a Disney property, there sure is a lot of Disney in it," Dot groused, crossing her arms over her chest. "We're probably going to get confused for Mickey Mouse over this by the studio present."

"That was just me," Yakko replied, looking to the audience. "True story, look it up."

"After you read the chapter, of course, and leave a review," Wakko added. "Hi JDF Legacier Morphicon"

"On with the show"

Ben and Kim were having a movie date, laughing at a comedy. Ben smiled at his girlfriend before he 'yawned,' leaning over and putting an arm over her shoulder. Kim looked up at him, smiling, leaning into him as they continued to watch the comedy.

"Undocumented life form detected," the Omnitrix beeped glowing yellow

"Sh," another person in the theater hissed

"I gotta go," Ben whispers.

"Hurry back," Kim whispered back.

Ben moved through the theater discreetly, looking at the Omnitrix guiding him toward the unregistered alien.

Ben had no idea what an alien was doing in a movie theater.

Walking past a janitor's closet, Ben heard someone groan. Ben opened the door to see a theater employee on the floor holding his head. "hey, are you okay?"

"I don't know. One minute, I was heading to the projector room. The next, something hits me in the head, and I'm here," the employee answers with a dazed look on his face.

"What projector room? The guy who hit you might be there."

"Theater 12"

That was where he and Kim had been watching a movie. If the projector worker had been here, who would have been in the projector room? Running back, Ben spotted the projector room. The door was open, and Ben could see a purple lizard with eight limbs fiddling with a machine while a large alien with blue fur and purple polka dots was tied up with a green guy, an eyeball taking up most of his face.

"You're not going to get away with this, Randall," the green eyeball said

"I got away with getting to the human world and snatching you two from your apartment, Wazowski," the lizard sneered, moving over to some machine connected to a door

Red energy that sparked and shook inside a yellow can be connected to some tubes. "All those humans screaming in that 'monster' movie or laughing at some dumb comedy with jokes as lame as yours; I'll have all the laughs and scream energy I need to turn Monsters Inc. and all of Monstropolis into a smoking crater."

"You're going to destroy millions of lives for what Randall did because I was a better scarer than you," the blue guy said, looking horrified

Ben couldn't blame him. That was messed up.

"I am the better scarer than you, Sullivan. I was twenty years ago, and I am now," Randall sneered, getting in the blue guy's face. "And with Monster Inc. as ground zero for the worst catastrophe in our world history, yours and Wazowski's names will be the most hated monsters in history."

"New life form located," the Omnitrix chimed before scanning the three Monsters. "New DNA cataloged."

Seriously, where was the volume button on this thing

Randall turned and vanished.

The door slammed open, hitting Ben and knocking him back as Randall appeared. "don't you know it's rude to eavesdrop, kid?"

"Don't you know it's rude to plan to blow up an entire city?" Ben said, "It's hero time." Activating the Omnitrix, he slammed down on it

Ben grew to be eight feet tall with hundreds of pounds of muscle to go along with it. Teal fur with purple polka dots grew horns from his head, the Omnitrix symbol on a wristband on his right arm.

Ben stood fully transformed. "Scream, Machine!" Ben yelled out, letting out a thunderous roar that shook the theater

In the horror movie, one guy elbowed his friend. "Dude, the surround sound here is awesome."

Randall vanished as Ben rushed at him, swinging his arms. Ben looked around, not seeing Randall before he got hit in the face. Ben tried to grab the invisible opponent, but Randall hit him from the side, pinning his arm against the wall before wrapping himself tightly around Ben's neck.

Ben gasped and choked, not able to get a grip on Randall or even knowing what to aim for when a root beer hit him, covering his head.

Ben grinned, punching Randall and knocking him out before looking at Kim. "Thanks"

"No big"

"The bomb," Ben remembered before rushing into the room and ripping the can out of the machine.

"Whoa, who's this guy, Sulley?" the green guy asked. "Why does he look like you."

"Long story," Ben said, tapping the Omnitrix, changing into XLR8, and zipping away with the can into the middle of the desert. He tossed the can high into the air, where it exploded. Ben let out a relieved sigh before he zipped back, untying the two monsters and taking Kim and the door away.

"Okay, I'm confused. Who are you, and how did you turn from Sulley into whatever that is?" the green guy asked

"I was wondering the same," Ben said, changing back to human form

The two sides told their stories.

"So you found a device that lets you change into alien forms, and you spotted us because monster DNA wasn't in your thing, which is how you turned into me."

"And apparently, monsters in the kid's closets are scarers who work for power plants that use screams as green energy, but you converted to laughter because kids are harder to scare than usual."

"If it makes you feel better, we were way more scared of you than you were of us," Mike said, looking sheepish. Sulley also looked apologetic.

"Well, you're doing better."

"Yeah, after Randall and Johnny nearly blew up, the city monsters have warmed up to laugh power," Sulley said, smiling. "Speaking of the city, we need to head back. Come on, Mike,"

"Yeah, I'm coming."

Mike opens the door. Sulley looks to Ben, holding out his hand. "Keep doing what you're doing, Ben."

"I plan to," Ben says, shaking Sulleys hand. Sulley smiles before walking through the door, closing it behind him, and returning to their world. Ben looks at Kim.

"So we probably missed the rest of the movie."

Kim shrugged, giving Ben a kiss on the cheek. "That's okay. We can see it again later," Kim said. Ben smiled, changing into XLR8. "Need a lift home."

"Gladly," Kim replies. Ben picks her up bridal style before running off and heading back to Kim's house.

Special thanks to Number Boy. These three chapters take place between chapters 9 and 10. We will be going to the Ultimate Alien part of the story. The last few episodes of Ben 10 ALien Force are just like in canon, except Kim is there.
