Author's Note: HAPPY HALLOWEEN EVERYONE! Here is a new story coming at ya! I originally wanted to set this up during the month of October but real life has makes you have other plans so I'll settle on uploading the opening at the end of the month…..which is today in fact!

This story has been brewing in our minds for a long time and I feel like the time has come to get this going.

A bit more info on the story will be added at the end of this chapter, so take a seat, eat some Halloween candy if you got them and enjoy.

September 24, 1989...

It was a dark night in New York City, illuminated only by neon and headlights.

Inside the Museum of Natural history, the usual pair of night guards watched the security screens. One was of large size with a thick mustache, the other was thin and much taller.

"Man, can you believe this?" The large guard said between a bite of his hoagie, "How much of our tax dollars do you think go into this?"

"None at all, Mark." The other guard replied. "It's a private event. Independently funded. Technically WE are funded by tax dollars."

"Yeah, yeah." Mark said with a hand wave. "But I just don't know why you'd want to go to this thing."

"Well...I mean," his coworker responded, pointing at a pamphlet in his hand. "You know what goes on in this city all the time, kinda makes sense they'd have a convention for it. I might learn a thing or two. Plus, we are loaning a few artifacts over there. Feels right to check in on 'em, ya know?"

"Jim, I think you need to take some REAL time off," Mark replied. "Like...a vacation. Outside the city. It'll be good for you."

"Sorry," Jim said. "NYC, born and raised! You won't catch me in some cabin in the middle of nowhere."

"Ah, don't knock it so soon," Mark said as he took another bite. "I swear your generation is..."

Mark's attention was cut short as he glanced back at the monitors. Three out of the ten screens were incredibly blurry, and a fourth was about to join them.

"The heck...?"

"What's up, Mark?"

"Most likely a loose wire," he responded. "I'm just going to check it out."

Mark made his way out of his chair and out the door with flashlight in hand.

He walked down the hallway, carefully investigating the walls for signs of clues. Remembering the layout of the cameras, he figured the first stop would be by the Early Man exhibit.

As he made his way past fossils and skeletons of beasts long since passed, a sudden chill ran down his spine. Looking down, Mark noticed what looked like a low fog passing by his feet.

"What the...?"

Pointing his flashlight downward he followed the fog to see where it was thickest. It seemed to come from the next exhibit.

Mark made his way inside the exhibition room. His flashlight revealed a plethora of glass cases obscured by heavy fog.

As he turned around he yelled in fight, seeing a dark, horned figure in the fog staring at him. Mark jumped, slamming his back into a display case in terror.

After yelling for about half a minute he came to realize his attacker was... just a statue of an ancient deity.

Mark sighed in relief.

Catching his breath, he turned around to see what he backed into. Luckily, the glass was thick and his act of panic didn't even crack the surface. He peeked past the glass to see the artifacts inside. Most were pretty unextraordinary; a vase, a few coins, and several prices of copper jewelry. But the piece that caught his eye was a staff (or at least, that's what the plaque said it was).

The staff appeared to be made from a human arm; dried and mummified. Inside the arm's clenched hand was a skull-shaped talisman, about the size of a softball. Mark tried his best to not look at it.

"Can't imagine WHY anyone would pay money to see that," he scoffed.

Mark turned around and resumed his search for answers. After about a minute, a noise forced him to look back; the sound of glass being broken.

That's when he saw it, the display case he was just looking at with a large hole in it, shards everywhere. As he security alarm rang he discovered that only one object was taken, the staff.

Mark grabbed his walkie-talkie and began to shout.

"JIM! WE HAVE A BREAK IN! DO YOU READ?! I REPEAT! WE-"

Suddenly, a loud moan emitted from nowhere. In an instant, the alarm shut off and Mark's walkie-talkie went dead.

Mark began to sweat despite how cold it was in the room.

He didn't even see it when it pulled him into the mist.

Back in the security room, Jim was holding onto his walkie-talkie.

"Mark? Can you hear me, Mark?!" He said in a panic. "All of the cameras are down! I can't get a visual, please respond!"

No luck.

Worried that his co-worker might be in danger he grabbed his flashlight and handgun. He rushed through the hallway and right into the mist that seemed to be spreading.

"Mark? Can you hear me? Mark!"

Jim felt a rush of air pass him, forcing him to jump back and twist around.

"Alright! I know you're there!" He said nervously. "Show yourself! I am armed!"

A shadow began to emerge from the fog, revealing itself as it approached. The figure was in a dark purple hood and robe with a black cape. It had a large hump with a slouching gait. It's arms were at least twice as long as a human's should be, ending in large, clawed hands. As the figure got closer Jim could make out more details about the thing's horrible face. Long, white hair peaked from its hood. Its face looked like one of a mummy with sharp teeth, no nose and red eyes. The figure's lower jaw was large and wide with a pointed chin.

Jim could only shake in fear as the figure floated closer to him.

"Where...is...the...caaaaaaaasket?" It spoke in a raspy voice.

"Wha...what are you-?"

"WHERE ISSSSSS IIIIIIIIIT?!"

"I...I...d-d-don't know!" Jim replied.

"Then yoooooou shall be...the firrrrrrrrst..."

The figure lifted one of its hands, revealing the staff from the display. It whispered into the artifact:

"Exsurge, dilecte mi! Apprehnde Infinitum!"

The talisman in the staff began to glow and an eerie red light as sparks began to emit from it.

The figure rose it's arm into the air, pointing the staff upwards.

"Come...forth!" It cried out.

Jim could hardly contain his fear as he watched two spectral creatures appear out of thin air. They looked like blue blobs with frog-like faces and human-like arms.

"TAAAAAAKE HIIIIIIIM!"

The pair of ghosts grabbed hold of Jim, dragging him into the fog, screaming.

The mysterious figure noticed something fall out of Jim's pocket. Curious, the cloaked stranger stretched it's long arm to pick it up off the floor. It was a pamphlet. The cover read:

First ever NYC Occult Con! Only at the Jacob Javits Center. Event starts at 10 am, September 26th.

"Of courssssssse, it makes sensssssse..."

The figure crumpled the pamphlet in it's claw in frustration as Jim's screams were slowly drowned out by the laughter of the ghosts.

"No one...isssss going...to meddle thisssss time...NO ONE!"

[Play the instrument theme to Scooby Doo Where are you]

The camera shows a spooky old mansion with bats flying around, then the camera lowers to reveal the Mystery Inc gang behind a Ghost (The Icon Ghost from Ghostbusters) tied up with rope.

Who you gonna call, Scooby Doo? When the ghosts are getting too real.

Fred moves in to remove the mask but only manage to pull off the head. The gang screamed as Fred drops the head and they run while the Ghost phases out of the rope, puts its head back on and chases after them.

Who you gonna call, Scooby Doo? When there's no mask to unveil.

The Gang continues to run away from the Ghost as they are chased inside the mansion.

Call us, Scooby Doo, we'll come through. From the biggest to the smallest.

As the ghost chases the gang around inside the Mansion, Scooby finds a phone, picks the handle up and starts speaking into it until Shaggy pulls him back as the Ghost tries to grab him.

Weather it is grime or made of slime. Just get your phone and call us.

Soon enough the gang run out of the mansion and into the Mystery Machine as they drive away with the Ghost floating after them.

We know you got a mystery to solve. But, Scooby Doo, you'll need more than a trap. Can that yap.

The Camera changes to show us side view chase scene with The Ghost chasing the Mystery Machine into a tunnel.

And, Scooby doo, with your crew. You're going to need more than a Scooby Snack. That's a fact.

Then the Ghost ran out of the tunnel being chased by the Ecto-1 and the Mystery Machine right behind it.

Scooby Dooby Doo, we're with you. Whatever threats that will come.

The Ghost runs back inside the Mansion and starts quickly barricading the door only for it to be knocked down by the Ghostbusters holding their Proton Packs at the ready and the Mystery Inc gang watching safely behind them.

We're ready to believe you, Scooby Doo. Together we can bust them!

Now the Camera has us behind the Ghost as it runs away in fright until we see the energy bolts from the Proton packs start circling around the ghost and the energy forms into words and trapping the Ghost in the No-Ghost sign serving as the first letter of Scooby's name in the title.

Who You Gonna Call, Scooby Doo?

By Z-King and Lord Primeval.

Author's Note: Hope you guys liked that! And can you believe no one on this site has made a Scooby Doo, Real Ghostbusters crossover yet? Well, no doubt someone will now after this I bet.

So, to clarify we are sticking with the Real Ghostbusters version of the group, focusing mainly on the first and second season of the show.

And as for the Scooby gang, their continuity is sometimes muddled, so me and Lord Primeval are just sticking with what we believe fits them best, design wise think of 90's version going from Zombie Island to Cyber Chase as for who their voices are, well let's leave it up to your imagination.

I hope this helps when you read the story, and stay tuned there is more to come but until then have a safe and Happy Halloween!
