It is late morning as Scooby Doo and company stand next to the Mystery Machine, which is parked alongside an old cobblestone street in the Russian village of Kedifion; the group of investigators are in the midst of conferring with their magical friend Vincent Van Ghoul who is communicating with them via a crystal ball which is being held by Fred Jones.
Vincent sits at a large wooden desk in his castle in deep thought as he ponders what Mystery Inc. has told him about them finding Rangor, the thirteenth ghost from the Demon Chest; he stands up and walks over to a large electronic device which resembled a large GPS system, after checking a few of the instruments he returned to his desk and turned his attention back to the crystal.
"Fred?" Vincent asked.
"Yes?" Fred responded.
"How is your investigation into the thirteenth ghost progressing?" Vincent asked.
"Good," Fred replied.
"What have you found out about Rangor so far, does he have any weaknesses, have you tracked him to a particular area?" Vincent asked.
"Well we have seen him already" Daphne responded with a frown.
"Yes and we've already had to use our powers to show him that we mean business and that we intend to capture him" Fred added.
"Where exactly did you first encounter him?" Vincent questioned.
"Daphne and Fred were telling us that they saw Rangor in an area of the village flanked by several different shops, after that they rejoined us and then we decided to contact you" Velma explained.
"Interesting, I should tell you that prior to you five contacting me I was checking my spectral scanner and it appears that there is some powerful spectral activity in your general area" Vincent replied.
"Ruh-Roh," Scooby whimpered.
"Mr. Van Ghoul?" addressed Daphne.
"Yes Daphne?" Vincent replied.
"Based on what you said, and that you mentioned there was a heavy amount of ghostly activity in the area; we should be seeing that ghost again. " Daphne remarked.
"Correct," Vincent replied.
"Well, now that we know he's nearby, what should our next plan of action be?" Fred asked.
"Hmm… the five of you have been investigating supernatural based mysteries for years; in fact all of you were exposing phony ghosts and monsters long before I met you, so I would suggest that you plan to set up a trap for Rangor" Vincent advised them.
"That's true. We've had a lot of success catching ghosts," replied Daphne.
"Like not to mention our transformation powers. We have those at our disposal if we need them," remarked Shaggy.
"Thank you for the advice, Mr. Van Ghoul" Velma responded.
"You're welcome, Velma; like I said, you five are the ones with the experience in unraveling supernatural mysteries. I just wanted give you all some advice to assist you in your endeavors. Now, use what I told you and your powers to find Rangor. I don't think I need to remind all of you of what would happen if he isn't caught." Vincent replied sternly.
With that, Vincent's image faded from view. The gang stood outside the Mystery Machine, conferring over their next move.
"So how do we plan on catching Rangor, Fred?" asked Daphne.
"We simply look through the village and surrounding area until we find him." responded Fred.
"Like, considering he's the most powerful ghost from the Demon Chest, I just hope we can find him… and if we do, it hopefully won't be too late." Shaggy nervously commented.
"Don't worry, Shaggy. We'll track him down, even if we have to travel to the ends of the earth!" Velma declared.
"Right, come on gang let's find that ghost!" Fred exclaimed.
Mystery Inc. walked along the quaint cobblestone village streets hoping to locate the final and most dangerous of the thirteen ghosts; the group passed by numerous vehicles, as well numerous old buildings which housed all manner of shops, restaurants and other businesses; while there were only a few townspeople out on the streets, those that were outdoors looked over at the group of four teenagers and one Great Dane wondering what they were up to.
The Great Dane sniffed along the road looking for clues as to the whereabouts of the gang's ghoulish foe; suddenly Scooby caught a whiff of something and began running with the rest of Mystery Inc. following, after running for several minutes the canine sleuth suddenly froze.
"Scooby, why did you stop running?" asked Velma.
"Yeah Scoob, what's up?" Shaggy added.
The Great Dane turned towards the gang, pointing the way he had previously been looking at a strange green glow; Daphne's hearing which was rendered quite sensitive after using her powers, picked up a deep rumbling and shaking sound.
Mystery Inc. stood by trembling in fear as the mysterious green glow beginning to get larger; the glow began to form a large shadowy figure, then began to change into a large, green, phantom-like creature taking shape, when suddenly the creature spoke.
"Well, well, well look what the cat dragged in; the mere children that Vincent Van Ghoul sent to stop me have returned," Rangor mocked them with an evil smirk on his face.
"Correct you creep, we're back and this time we will stop you!" Daphne bellowed as anger filled her voice.
"Stop me, ha; even with the powers that Vincent Van Ghoul gave you, do you honestly expect to defeat me, Rangor the thirteen and most powerful ghost from the Chest of Demons?" Rangor laughed evilly as the gang gave him a disgusted look.
"That's what we intend to do, we've stopped ghosts like yourself before and we can do it again!" Fred added with increased vigor in his voice.
"You poor pathetic mortals, in all the years that I have been free from that blasted Chest no one has ever been able to defeat me and no one ever will!" Rangor bellowed.
"There's just one thing you haven't counted on Rangor" Velma replied.
"What's that?" he replied, as he attempted to finish his appointed task.
"Like you're talking to Mystery Inc., one of the greatest groups of detectives to ever solve mysteries" Shaggy remarked.
"Right, and we've had a friendship that has been going on for numerous years; not to mention we also have powers that surpass anything you've ever seen" Fred added.
"Friendship, ha! what powers does friendship have that could or can surpass anything that I have or for that matter anything that any of the thirteen ghosts possess?" Rangor sneered.
"You would be surprised, friendship is one of the most powerful emotions of all" Daphne commented.
"And nothing can defeat friendship, nothing" Fred added.
"So you five think that friendship in addition to your superpowers will be the combination that will put me back in that infernal chest?" Rangor asked.
"Yes Rangor, we not only think so; we know so!" Daphne remarked.
"Very well, let's just see about that once and for all!" Rangor replied, as he moved ever closer to Mystery Inc.
Rangor began cackling evilly as he moved backwards; he rose into the air and became surrounded by an eerie green whirlwind, strong hurricane force winds surrounded Scooby and company as they prepared to tangle with the wicked apparition.
"Now, do you meddling kids and your dog still think you can defeat me?" Rangor taunted, his voice cutting through the wall of hurricane strength wind as well as the omnipresent green glow, which was still surrounding the group.
"We most certainly can, come on gang let's show this phantom just exactly what Mystery Inc. can do!" Fred confirmed.
The rest of the gang nodded in agreement with Fred's statement and prepared to take down ghost number thirteen.
Each member of Mystery Inc. stood still in deep thought, trying to figure out the perfect animal or creature to transform into; the five sleuths knew that they would have to choose strong creatures in order to have enough power to defeat Rangor and they hoped they had picked right as each sleuth began to change.
Fred was the first of the group to undergo his transformation, the face was the first part of his body that underwent noticeable changes, as coarse brown fur grew over every inch of his face; Fred's ears became pointed and grew out of the sides of his head, his usual blue collared white shirt and orange ascot ripped and tore apart as more fur grew where his shirt and ascot once were, his arms began to change as the sleeves of his shirt ripped apart as well; the pair of blue jeans he was wearing ripped apart at the seams as yet even more brown fur covered his legs, lastly his brown shoes tore apart as his feet began a strange metamorphosis into sharp claws, finally Fred's transformation had finished, and he had chosen to become a Cat Creature.
Daphne began to transform next, she noticed that her face began changing shape, thick brown fur grew and covered every inch of her face as well; next, her ears were became pointed, she could feel her beautiful purple knit dress become torn to shreds as yet more fur grew where skin had been; her arms which only a few minutes ago were a thing of beauty became something out of a horror movie and covered in fur as well, her human hands were also becoming sharp claws and her legs which only seconds ago were covered in pink stockings also started to become furry; lastly, her feet were beginning to change into sharp claws as her purple heels tore apart, Daphne Blake had finished her transformation and like Fred had also chosen to become a Cat Creature.
Velma was the next to transform, she could feel her face changing shape; her face also began to grow brown fur while her human nose stretched out into a round black animal nose; her ears become pointed like those of a wolf, her teeth were becoming razor-sharp while her brunette-brownish hair became somewhat messy, her hands were becoming covered in thick fur as well, in addition she noticed that her finger nails were becoming sharp black claws; unlike Fred and Daphne, her clothing did not become torn and ragged as brown fur continued to grow all over her body, the parts of her legs that were not covered up by her long orange socks became covered in brown fur as well; her shoes began tearing as her feet were becoming furry brown paws in addition to that her toenails had become sharp black claws like the ones that had grown out of her hands, she could also feel something growing out of the back portion of the bottom of her skirt which in this case was a large brown wolf tail, finally Velma had finished transforming and she had chosen to become a Werewolf.
Shaggy was the next to undergo his transformation, he was a bit nervous as he started the strange magical metamorphosis into the creature he had chosen; he briefly looked over at Velma and saw that his female companion had become a Werewolf, the cowardly teen hoped and prayed that she would be ok and come out of this whole ordeal unscathed; during the strange transformation he briefly thought back to that fateful Halloween night when she had become a Werewolf the first time; he also briefly remembered the night when he visited Austria and his family's ancestral home and the man that had used an old medallion that belonged to his family to transform him into a horrible, snarling beast.
He remembered another girlfriend he had named Googie, when the moon shone on him while he was on a date with her at a local drive-in transforming him into a snarling howling creature of the night yet again, after which Count Dracula forced him to compete in the annual Monster Car Race, during which he had to use all of his skill and luck to win otherwise he would still have been a Werewolf during their current adventure; his thoughts now returned to the present and as he looked around he saw his friends Fred and Daphne, and his companion Velma finishing their transformations; Shaggy realized that it was now his turn to face the music.
The cowardly teen stood still as he underwent the strange metamorphosis; first he could feel his face changing shape, his nose and jaws stretched out and he could feel his ears become pointed and animal-like; brown fur had also started to grow all over his face and body; his arms began to change as they also became covered in coarse brown fur; he felt his legs transforming and becoming covered in fur as well, lastly his feet started to stick out of his black shoes as they began to change into the paws of a wolf complete with sharp black claws.
The cowardly lanky teenager who was and had always been frightened of any and all monsters, ghosts and supernatural creatures had put aside his life long cowardice and became one of the very things that he had been afraid of all these years, a monster; more specifically a Werewolf.
With the rest of Mystery Inc. already transformed, Scooby took his turn at transforming; because he was not human like his friends, the Great Dane's transformation was a little bit different than the rest of his detective friends; the cowardly canine began to change into his chosen creature, his ears became bigger than usual, his face began to become more beast-like and his fur became thicker and more dense than it usually was, his tail changed from a smaller dog's tail into a large wolf's tail; the Great Dane noticed that the nails on each of his paws grew into longer black claws, Scooby Doo had also become one of the very things he disliked, mainly a Werewolf.
Each member of the crime solving detective agency Mystery Inc. had finished utilizing their somewhat frightening but necessary transformations into half animal-half human creatures; while each of the teenage sleuths underwent their respective metamorphosis, Rangor stood in somewhat amazement as the gang stood at attention ready to do battle in their new forms against him, similar to what a regiment of troops would do in preparation for battle against whatever enemy they faced.
Fred stood in the middle of the street as he prepared to lead his friends into combat; he took a deep breath and prepared to give the order to attack the ghastly green phantom.
"Ready gang?" asked Fred in a feline-like growl.
"Ready!" replied the rest of Mystery Inc. in unison.
"OK, let's get that ghost!" Fred declared.
All at once Mystery Inc. charged towards Rangor with claws fully exposed, Fred and Daphne went for the ghost's arms, with Shaggy, Velma and Scooby going for the phantom's chest and upper body.
With their sharp long black claws Shaggy, Velma and Scooby reached for the ghost's chest and using their new appendages tore through Rangor's upper body.
"Ugh, blasted meddling mortals!" Rangor cried out as he stumbled backwards.
"Good work guys, now let's hit him again!" commanded Fred.
This time Fred and Daphne opened their mouths to reveal sets of sharp cat-like teeth; almost simultaneously the pair bit down on Rangor's arms, Fred taking the left one and Daphne taking the right one.
"Rangor looks like he's weakening; Shag, Velma, Scooby get the Chest of Demons ready!" Fred cried out.
However even with limited strength Rangor heard this and prepared to give the gang a wake-up call.
"So you five still plan to trap me in that blasted Chest of Demons? Well I'm going to see to it that doesn't happen!" taunted Rangor.
The immense green phantom-like creature inhaled taking a large amount of air and then exhaled, sending the gang backwards and onto the ground.
"Everybody all right?" asked Fred.
"I'm OK," replied Daphne brushing herself off.
"Likewise" said Velma.
"Me and Scooby are fine too," Shaggy added.
Mystery Inc. finished brushing themselves off and tried to stand back up in the strong almost hurricane force winds that Rangor was blowing.
"Freddie, no matter what we do we still can't get him down, what are we going to do?" Daphne asked.
"Gang listen carefully, we will get Rangor down and we will capture him in the Chest! now I have a plan everybody huddle up and listen carefully" Fred declared.
Fred, Daphne, Velma, Shaggy and Scooby got in a small circle and began whispering to one another; after a couple minutes or so, the gang broke the huddle and stood back up.
The gang stood in front of their ghostly foe, at least Daphne, Velma and Shaggy did while Fred whispered something to Scooby; the Great Dane turned Werewolf nodded at what Fred had told him and ran quickly behind Rangor.
The four teenage investigators stood in silence before Rangor smiling; the fearsome ghost was confused by this and spoke up.
"What are you mortal children doing?" Rangor hissed.
"We're just standing here admiring your power and the surrounding scenery, is there anything wrong?" Fred asked.
"I could have sworn there were five of you a second ago, I'm certain there was a dog here with you mortals" Rangor hissed.
"Oh you mean Scooby Doo, he decided to take a walk" Fred explained.
As he spoke the ghastly phantom was unaware that Scooby Doo was in point of fact right behind him, he didn't think of anything of Fred's statement and spoke again.
"You meddling mortals are up to something," Rangor thought.
"Well, actually we are up to something" the blond teenager confirmed.
"Aha, I figured as much; just what are you four up to?" the green ghost wondered.
"We want to make you a proposition," Fred explained.
"Oh you do, what kind of proposition are you proposing?" Rangor replied curious as to what the leader of Mystery Inc. could offer the thirteenth ghost.
"The proposition is this: we've decided we want to team up with you," Fred explained.
"We have?" Daphne asked surprised.
She looked over at the blond teenage sleuth and she did so, he winked at her and at Velma and Shaggy as well.
"Oh yeah we have" the redhead added, realizing what Fred was up to.
"Really?" Rangor asked, almost surprised by this turn of events.
"Yes, think of it; the four of us and Scooby-Doo with our shape-shifting powers and you as the thirteenth ghost from the great Chest of Demons, we would be unstoppable" Fred explained.
Rangor thought for a few moments about the proposal the blond teenager had given him; at first he thought the mortal was trying to trick him so that he and the gang could capture him in the Chest of Demons, however the ghost decided he was being serious and then smiled.
"Very Well, I accept your proposal" Rangor said with an evil smirk.
"Good, let's seal the partnership with a good luck handshake" Fred declared.
"What about the other three?" Rangor asked.
"We'll be included in this partnership as well" Daphne replied.
"Sounds wonderfully evil to me," Rangor declared.
"Good, come on gang let's give him a Mystery Inc. hearty handshake," Fred explained.
Fred, Daphne, Velma and Shaggy each stepped forward with their hands extended to give the ghost a handshake when each of them started to run towards the ghost with outstretched arms and claws showing and pushed the ghost towards Scooby; Rangor stumbled and fell backwards tripping over Scooby's four legs.
"Why you blasted meddling kids!" Rangor hissed in pain as he sat on the ground rubbing his ghostly ankle.
"You five tricked me; I've been haunting the earth for hundreds of years and never have I fallen for such an underhanded, low down dirty trick!" Rangor angrily remarked.
"Now Rangor, we're going to lock you away forever so you won't do any more harm to the world," Fred declared as he opened the lid to the Chest of Demons.
As the Chest opened a strong force began to pull Rangor towards the sinister container.
"You meddling kids, you shall all pay dearly for this; you will all paaaaay!" Rangor shrieked as he was sucked back into the chest.
After Rangor was safely encased inside the Chest of Demons, Fred closed the container's large stone lid; finally ending Mystery Inc.'s journey to the ends of the earth to track down the 13 Ghosts of Scooby Doo.
After the Chest was securely locked Fred, Daphne, Velma, Shaggy and Scooby slowly transformed back into their natural forms.
"Phew, it's finally over," said Daphne breathing a heavy sight of relief.
"Like I second that," replied Shaggy.
"Rand rhird" Scooby commented.
"Right, now each and every one of the ghosts from the Demon Chest is locked up as if the chest was in Fort Knox" Fred declared.
"And with any luck those creepy ghosts will never be heard from or bother anyone ever again" Velma added.
"Like I sure hope so Velma, I wouldn't want to track down those thirteen spooks all over again" Shaggy replied.
With Fred holding the Chest of Demons, Scooby and company started heading back towards where they had parked The Mystery Machine; after walking for some time Mystery Inc. arrived back at their vehicle.
As they entered the vehicle the crystal ball that Daphne left sitting on the dashboard of the van before the group went in search of the thirteenth ghost began to glow; only this time it was not a regular glow, but a very strong one.
The glow from the crystal was so strong that the gang stepped slowly away from the Mystery Machine and opened the doors of the vehicle so that whatever was happening would not hurt anyone.
The glow became clearer and began to materialize; two shapes, a small one and a bigger one began to appear, and as the two forms took their final shape the gang smiled as two familiar faces could be seen.
As the gang figured, the group's young friend Flim Flam and their powerful warlock ally Vincent Van Ghoul stood in front of them beside the Mystery Machine.
"Flim Flam, Mr. Van Ghoul!" Daphne exclaimed.
"Boy is it great to see you two again!" Fred declared.
"Likewise" Flim Flam said.
"How did you two get here?" Velma asked.
"Simple, we used the crystal ball's transporter mechanism" Vincent explained.
"I thought the transporter didn't work," the intelligent female sleuth wondered.
"It didn't at first Velma, but we were able to fix it so that we could see your defeat of Rangor back at the castle and then transport ourselves here to congratulate you in person" Vincent explained
"Thank You for coming Mr. Van Ghoul and we were sure glad to defeat Rangor and finally conclude this chapter of our lives" Shaggy explained.
"Yeah not to mention those shape-shifting powers that you gave us sure came in handy in our defeat of the thirteenth ghost," Fred explained.
"I'll say they did, in fact if it hadn't been for those powers we would have never defeated him" the redheaded female detective replied.
"Well I'm glad to hear you have defeated Rangor and that he's locked away in that chest; now the world can rest easy knowing that the thirteen foulest ghosts, ghouls and specters will no longer be a threat to the planet" Vincent remarked with much relief in his voice.
"Mr. Van Ghoul?" addressed Fred.
"Yes Fred?" Vincent asked.
"How do you really know the spirits from the Chest won't escape and try to take their revenge or anything like that?" the blond teen wondered.
"Very simple Fred, Flim Flam and I will make sure to protect the box and make sure that no villains will ever get their hands on it as long as we both live" Vincent explained.
"You know I've got a question for the gang Vince, if it's ok to ask" the young boy remarked.
"It's quite alright Flim Flam, go ahead and ask" the great warlock replied.
"OK, what are the five of you going to do now that Rangor's been defeated?" asked Flim Flam.
"I don't know Flim Flam, for now we'll probably head back to our motel, check out and head home" Fred replied.
"Fred, what about the Chest of Demons?" asked the redheaded sleuth.
"That's right we have to figure out what we're going to about it," replied Fred.
"I've got an idea," explained Vincent.
"What is it Mr. Van Ghoul?" addressed Fred.
"Why don't the five of you head back to the Himalayas and then we can discuss things further," replied Vincent.
"Good idea Mr. Van Ghoul, we'll do that" addressed Fred.
"Well, Flim Flam and I have to be going but we'll see you back at the castle" Vincent declared.
"See you later Mr. Van Ghoul," replied Daphne.
"Goodbye everyone" Vincent said.
"Goodbye Mr. Van Ghoul and Flim Flam" replied the gang as they waved farewell to their friends.
Fred, Daphne, Velma, Shaggy and Scooby saw Vincent and Flim Flam fade away as the pair returned to Vincent's castle via the Crystal Ball's transporter.
The gang got back into The Mystery Machine and drove back towards their hotel; after arriving back at the hotel the gang went up to their rooms, retrieved their luggage came into the lobby area, paid their bill and went back outside to the van.
After making sure everything and everyone was in the Mystery Machine, the gang headed back towards the private airfield where the gang had left their private plane.
Mystery Inc. made sure each person and all of the gang's belongings were on the plane; after which Fred climbed into the pilot's seat with Daphne in the co-pilot's seat, after Scooby and company were seated and buckled up the Mystery Flying Machine climbed into the Russian skies headed for the Himalayan Mountains and a final rendezvous at Vincent Van Ghoul's castle.
