A/N: Just to let you know, the 'Dawn of the Dead' part of the title of this story is not zombie related. I'll give you just a brief spoiler right here. 'The Dead' is the name of a Decepticon I made up myself. And this is another 'Transformers' crossover with 'Monsters Inc.' only Teenaged Boo will be in the story. Now let's get started with a opening monologue from Optimus Prime himself. Enjoy!

(Optimus Prime Monologue)

Dark Energon, an element capable of destroying worlds. That is how our home planet of Cybertron was destroyed, after it's usage by the Decepticons, a race of dictator robots who dreamed of nothing more but tyranny. The Autobots, who wanted to bring peace and justice throughout the galaxy forced the Decepticons and their entire supply of Dark Energon off the planet after it's core was corrupted, but we still lost the war. Now, it has brought us to the monster world, where the new battle has begun.

-MI: Transformers: Dawn of the Dead-

(Start playing 'What the Hell' by Avril Lavigne as you play this next part until I say stop)

19 year old Mary Gibbs, or 'Boo' as she liked to be called got up out of bed and got ready to meet Sulley to pick her up to spend her entire Summer break with him.

"Crap! I overslept!" she shouted. She then got out of bed, took a shower, and put on some clothes. She wore a black V-neck T-shirt with a skull and cross-bones with no lower jaw bone, and a pink glitter bow on top of it's head. Underneath that she wore a long sleeved black and gray striped shirt, gray skinny jeans, black combat boots, and some rubber bracelets for her favorite bands on her right wrist. She then put her hair in a half-up style and placed a pin in to to make sure it would stay in place.

"One more thing to do" said Boo as she took her suitcase out from under her bed and then took out her iPod touch, wallet that had a chain on it that was hooked to her spike stuttered belt, and her cell phone. Soon, the door opened up and Sulley came through it.

"Hey there" said Sulley.

"Hi, Kitty" Boo greeted and hugged her father figure.

"Love the new punk rock look. It fits ya" said Sulley as he patted Boo on her shoulder.

"Well, I am a music major at my college, and my band is a punk-rock band so... why not dress up like a punk rocker?" asked Boo.

"You ready to get going? Mike and Randy said they wanted to see a movie with ya" Sulley said. Boo nodded and dragged her suitcase with her into the closet and shut the door. Going into the monster world.

(Optimus Prime Voice-Over)

For the last few years, an advanced team of new Autobot soldiers have taken refuge on Earth under my command. Together, we hunt for what remain of our Decepticon foes, hiding in both the human and monster world.

(Normal P.O.V)

A red Lamborghini with a black Decepticon logo painted on the hood was driving through the streets and even drove through a coffee shop. Optimus was watching over from a taller building and activated his communicator.

"Wheelie, Longarm! Target is approaching you guys" Optimus said.

"We're on his trail right now, Prime" Wheelie said through the com-link. He was in the driver's seat of a white toe-truck with blue flames on the front.

"Alright, Longarm, let's show them that this world will be better off with one less Decepticon in it" said Wheelie with encouragement.

"Couldn't have said it better, myself" said the tow-truck through the radio. The vehicle then turned into a short Autobot who went by the name: Longarm. Wheelie was operating a shoulder cannon on Longarm's right shoulder.

"Grappling hooks engaged" said Longarm as he pointed his hands at the Lamborghini Decepticon. The hands shot out the arm sockets with metal slinky type ropes attached to the hands and arms and grabbed onto the back bumper of the car and it slowed down.

"You're not going anywhere, buddy" said Longarm. From a darkened alley came a 2014 yellow Camaro with black racing stripes. It drove up and stopped in front of the red Lamborghini. It transformed into the Autobot: Bumblebee, one who was good friends with Randy, Mike, and Sulley when they were college students.

"I have you now" said Bumblebee through a sound-file of Darth Vader in 'Star Wars Episode IV'. Bumblebee had his vocal processor ripped out by the Decepticon leader: Megatron back in the final days of the war on Cybertron, now he talks through radio and different sound files. Bumblebee shot the trunk and it missed because the car began driving backwards and knocked Longarm to the ground on his stomach.

"Have you blown your circuits!?" shouted Longarm as Bumblebee helped him back up. The Lamborghini then transformed into a Decepticon who looked like Bumblebee except he didn't have doors on his back like wings, and he only had one eye.

"Swindle, why am I not surprised?" asked Longarm rhetorically. Indeed, the name of this Decepticon was 'Swindle'.

"My lord wants something the monster world has, and we're gonna get it" said Swindle as he backed away slowly. But Swindle was stopped in his tracks by a Blue with red flames Western-Star 4900 custom semi-truck. Swindle looked behind him only to see the truck transform into Optimus Prime himself.

"Hand over what you have, Swindle, and maybe I'll let you leave with your spark still in your chest" Optimus threatened. Swindle then opened up his chest compartment and out of it came a large Dark Energon crystal.

"Dark Energon?" asked Longarm.

"Crap, this is the third time we've caught a Decepticon carrying Dark Energon" said Wheelie snapping his fingers in irritation. All of a sudden, Swindle pulled out a long sword from behind it back and tried to stab Optimus, but he dodged and kicked Swindle in the face.

"Say goodbye, Prime" said Swindle as he pulled out his blaster. But the gun was shot out of his hand by another gun. Optimus, Bumblebee, Longarm, and Wheelie looked to their left to see Ironhide with his guns out.

"Not on my watch, Decepticon punk" said Ironhide as he put his gun away. Optimus then took out his gun and pointed it at Swindle's head.

"Any last words, Swindle?" asked Optimus.

"This is not your planet to rule, Autobot. The Dead will rise once more"threatened Swindle.

"That doesn't sound good" muttered Wheelie quietly enough for no one to hear him.

"Not today" said Optimus. He loaded his gun and put an Energon bullet through Swindle's one eye. Once he was dead, Optimus crushed the Dark Energon crystal with his foot.

A/N: So, Boo will be staying with Mike, Sulley, and Randy over the summer. Also, Boo is in her college's punk-rock band. And the Autobots have caught and killed Swindle who was carrying Dark Energon, and carried a warning saying that 'The Dead will rise once more' and that sounds like bad news. Lots more to come in the next update. Please review, thanks!
