Author's note: Here's the next installment of my Coolsville Central series, folks!

This story is based on the 2013 Paul Welker movie Vehicle 19, and will tell the story on how Mystery Inc. got the Mystery Machine.

This is also the very first instance where Mystery Inc. teams up with Batman during the former's trip to Gotham City, hence the reason why this story is in the Batman and Scooby-Doo crossover section.

I don't own Scooby-Doo or Batman. Hanna-Barbera Productions and Warner Bros. does for the former while DC Comics does for the latter.

Chapter 1: Prologue

August 2, 2011

It has been more than a year since Daphne was kidnapped by a trio of embittered former employees of Blake Enterprises with support from a corrupt police lieutenant for ransom, only to be rescued by the rest of the gang, who were able to do so with the help of Tom and Jerry.

In the year since the kidnapping, life went on as usual for the gang, and they all returned to Coolsville Central High School in the September after the summer of Daphne's kidnapping, attending Grade 10 as sophomores.

It was also in the year since the kidnapping that the gang solved a few more mysteries, and in spite of a few mishaps, each of the gang's parents eventually warmed to their mystery-solving hobby, though they've continued to urge caution.

After Shaggy turned 16 in April, he applied to get his driver's license and after going through the driving tests, he eventually received his driver's license.

Fred will eventually follow suit when he turned 16 in late June, and from time to time, the boys will practice driving with their parents' cars and drive around.

In the meantime, Shaggy's father Sam Rogers received another promotion a couple months after the Blake kidnapping case, where his coordination of another anti-corruption sting led to his promotion to Deputy Chief, which placed him just two ranks below Chief of Police Gil Mason.

Upon his promotion, Sam became the new Director of the Detective Bureau, replacing Deputy Chief Llewelyn Storch upon his retirement, where he reports directly to Assistant Chief Derek Harewood as a bureau commander rather than as Harewood's assistant.

This promotion gave Sam more authority over the operations of the Detective Bureau, where he moved to reverse a lot of the changes former Deputy Chief JP Miller made during his tenure as Director of the Detective Bureau.

As Director of the Detective Bureau, Sam is in charge of not just Major Crimes Division, but also other divisions responsible for police investigations, such as the Forensics and Technical Investigations Division, the Personnel Support Division as well as Guns, Gangs and Narcotics Division.

After appointed Director of the Detective Bureau following his promotion, Sam made extensive leadership changes to the divisions under the Detective Bureau.

First off, Captain Brian Crowley was reinstated as commanding officer of the Major Crimes Division after he was ousted by Miller, who appointed Captain James Kenny to the post.

Kenny subsequently had his badge stripped on Sam's orders after the Blue Falcon's anti-corruption files have extensive red flags on him, not to mention that he was known for his racist views that frequently put him on a collision course with not just Lieutenant Nelson McCormick, but also Sergeant Nathaniel Hughes and Detective Charlie Chan.

Sam will never forget the moment when he demanded Kenny's badge and the captain attempted to turn the tables by pulling a gun.

The moment Kenny pulled his gun, a falcon-shaped boomerang suddenly appeared out of nowhere and knocked the gun off his hand.

Turning towards where the boomerang had came from, nothing could've prepared Kenny for what will happen next.

Sam backed out of the way just as the Blue Falcon tackled Kenny and slammed him against the wall in Sam's office, grabbing the corrupt captain by the collar.

"Let...let go...of me..." Kenny choked as the Blue Falcon glared at him intensively. "You...have...no right...to...be...here..."

"And you have no right to disobey Chief Rogers' orders and pull a gun on him, you useless, sorry excuse of a police officer!" BF gritted his teeth as he slammed Kenny onto the wall again while Sam folded his arms. "I've got extensive files on you, Captain, and they're painting a bleak picture on your future."

"Yes." Sam nodded. "You're looking at at least 15 years behind bars, Kenny, for corruption, fraud and extortion."

"Not to mention your prejudiced views on ethnic minorities strips away your right to wear a badge, scum." BF added. "In a society where we're interacting more people of different races, religion and ethnic groups, people like you are holding up progress on the nation's future."

"In addition to encouraging more cases of miscarriage of justice thanks to your prejudiced views." Sam added. "And I have no intention of having the likes of you infect my bureau of your racism."

"Now get up on your feet and remember where you've hidden your stuff." BF said as he let go of Kenny, causing him to fall onto the floor as he catches his breath. "If you misplaced them, I will be there and I won't be so pleasant the next time we meet."

As Kenny catches his breath, BF walked by Sam, who nodded.

"Thanks." He said to BF.

"No problem." BF nodded back.

Within seconds, two police officers stormed into Sam's office.

"You called, Chief?" The first officer asked.

"Yes." Sam nodded before turning to Kenny and added, "Escort Captain James Kenny out of this building and to Hanna-Barbera Court, where he is to have an appointment with District Attorney Skip Jones. And tell him that Kenny is no longer welcomed to this building."

"Yes, sir." The two officers nodded before proceeding to grab Kenny.

"You blasted son of a gun." Kenny said to Sam as he got up, escorted by the two officers. "I'll have your badge for your allowing the brutality of that vigilante."

"And you better be quick about that, because I heard the Blue Falcon doesn't like to meet criminals twice." Sam replied evenly. "Oh, is he going to be grumpy and mad when he sees you again."

Kenny huffed before the two officers prepared to drag him out of Sam's office, only for Sam to clear his throat.

"Your badge, captain." Sam said as he held his hand out. The stern look on his face tells Kenny that he has no time to waste.

Grumbling, the disgraced captain clipped his badge off his belt and handed it to Sam before the two officers dragged him away.

Anyways, another division targetted by Sam for leadership change was the Guns, Gangs and Narcotics Division, where he approved Lieutenant Daniel McBride's promotion to captain and handpicked him to command the division, replacing Captain Angus Scheer, who was placed in command of the division by Miller.

McBride was the senior patrol sergeant from the East Coolsville Division, where Sam initially worked at as detective commander when he was transferred back from New York in 2001.

Following Sam's promotion and transfer to Major Crimes Division, McBride was transferred to the Guns and Gangs Division, which was renamed as the Guns, Gangs and Narcotics Division in 2004 after then-Deputy Chief Harewood, as Director of the Detective Bureau, approved the GGD's merger with the Narcotics Division.

Anyways, like Kenny, Scheer became a victim of Sam's anti-corruption drive, especially after as many as 78 officers assigned to the Guns, Gangs and Narcotics Division were implicated in some form of misconduct in a scale not seen since the Rampart scandal of Los Angeles in the late 1990s.

Scheer was found to have kept a blind eye on the officers' corruption, even participating in the fabrication of evidence and covered up evidence of the activities.

McBride never had a good working relationship with Scheer after he was brought in from the South Coolsville Division to command GGND. In fact, McBride's concerns on the officers' conduct fell onto deaf ears when he went to Scheer to express concern.

Miller's replacement Storch did act on McBride's concerns, ordering an internal inquiry, though Storch himself was unsatisfied by the investigation outcome conducted by Internal Affairs.

It took the shooting death of an unfortunate bystander to cause a public outcry that led to an outside commission appointed by the DA's office to investigate McBride's allegations, resulting in the scandal blowing up.

By the time Sam became the Director of the Detective Bureau, his first act was to order an investigation into Scheer's role in the scandal, an investigation that ultimately costed Scheer his badge as Sam, too, ordered his dismissal.

In the same time, though, Sam was amazed by how Mason was able to hang onto his job as police chief in spite of the scale in the scandal.

After all, over in Los Angeles, the police chief that oversaw the department during the Rampart scandal didn't have his contract renewed and got replaced in 2001.

At the thought about Mason, Sam was beginning to wonder if his contact's contact's warning on Mason may be justified.

After all, Mason was a deputy commissioner of the Gotham City Police Department prior to his transfer to Coolsville, and the GCPD was also known for its rampant corruption prior to the ascension of his contact.

Anyways, Sam's promotion to deputy chief and appointment as Director of the Detective Bureau was, once again, met with annoyance from his nemesis Deputy Chief Rupert Gosnell, the Director of Internal Affairs.

Sam figured that Gosnell was still smarting over his being passed over for appointment as chief in favour of retaining Mason as the city's top cop.

However, Gosnell had another reason to be smarting by Sam's promotion, because not long after Sam was appointed as Director of the Detective Bureau, he requested the city's Auditor General to conduct an audit in the activities of Internal Affairs, a request sustained by the DA's office.

Anyways, after his appointment as Director of the Detective Bureau, Sam also approved the promotion of Captain Jared Stephenson to inspector, along with appointing him to be his assistant.

Following Crowley's initial promotion to captain and taking command of the Major Crimes Division, Stephenson moved to command the Central Division and did a significant amount of work cleaning things up there. It was a work he continued as Miller, and later, Storch were later appointed as Director of the Detective Bureau.

With Inspector Stephenson the Assistant to the Director of the Detective Bureau, Sam figured that he can make matters easier for his efforts to reform the bureau.

That day was also the day George Blake travelled to Gotham City for a business trip, though as it turned out, the gang have entered themselves into a contest at the mall and ended up winning five two-round trip plane tickets to Gotham City.

And that's how George came to find himself in the economy class of a Trimm Air domestic flight, flying from the Coolsville Hanna-Barbera International Airport to the Gotham Robert Kahn International Airport, together with members of Mystery Inc.

Given that Gotham is located in the state of New Jersey, the flight is slated to take around two-three hours with no need to change the time on their clocks, as both Gotham and Coolsville are within the Eastern Standard Time Zone.

"I never thought we were going to end up travelling to visit Gotham City together, gang." Fred spoke as the flight remained airborne.

"Me neither, Freddie." Daphne agreed.

"Well, when we get there, kids, I want you all to stay together and travel together." George said to them. "Gotham's a very dangerous place for one to be alone in the streets, especially at night."

"It's like Coolsville in many respects, Mr. Blake." Velma said as she looked up from her guide book on Gotham City. "But without the crazy people running around causing trouble."

"Indeed, Velma." George nodded. "Not to mention the Bat lurking in the shadows at night looking for someone to prey on. Stay out of trouble unless you want to end up running afoul of him."

"Like, I'm sure this Bat is the same as BF, Mr. Blake." Shaggy said confidently.

"You don't know the Bat." George said. "He's tougher than the Blue Falcon in many respects and will never rest until a loose end in a case is tied up."

"We'll be fine, Daddy." Daphne insisted to her father. "It's not like we don't know how to handle dangerous situations while mystery-solving."

"Besides, I don't suppose there's a need for us to split up to tour the city alone, since Gotham doesn't strike me as a tourist-oriented place." Velma added.

"Just stick together and be safe." George said sternly. "I don't want any of you to end up going through what Daphne had to go through last summer-"

"Dad, there's no need to-" Daphne protested, only for her father to cut her off.

"You could've gotten yourself killed, dear." George said. "In the months after the rescue, I still have the occasional nightmare about something terrible happening to you, and as my only child, money can't buy me comfort if I lose you."

"Daddy, I can manage myself." Daphne said. "If you keep shielding me from any potential dangers the world has to offer, I will never have the chance to explore the world on my own and end up having to rely on you, and do you honestly want me to do that as I reach adulthood?"

George sighed as he looked at his only daughter before glancing at Shaggy and Scooby.

"No." He finally said as he placed his hand on her shoulder. "Just take care of yourself, dear."

"Don't worry, Dad." Daphne said. "I can manage it."

George nodded thoughtfully just as the captain reported that the flight is due for landing at Gotham Robert Kahn International Airport in the next five minutes, advising the passengers to return to their seats and fasten their seatbelts.

What awaits the gang as they arrive at Gotham City?

All I can say is stay tuned, and please read and review!
