Author's Note: Hello, users at Fanfiction! This is my first real ongoing fanfiction/crossover for you all to read! I've been on/posted to this site before, but never truly had the chance to upload a full-length story before this one. Now I am aware that there are already a few other Scooby-Doo/Spider-Man crossovers on here, but, in my honest opinion, this one is truly unique in the sense that it involves not only Spidey and the Mystery Gang, but also features several other characters from both franchises such as Peter Parker's friends as well as the Hex Girls. Also, based on the title alone, you can most certainly tell this one will be about them taking on Mysterio whom I believe is the most fitting candidate for a villain to bring both parties together. So, without further adieu I present to you...

Scooby-Doo Meets Spider-Man: Manhattan Mystery - The Menace of Mysterio

'Twas the finest day in the busy streets of Manhattan, New York. Cars drove across the gridded expanses of road that lined the city en route to their destinations. In addition to exhaust fumes, warm, Spring-filled air poured its way throughout the atmosphere, effectively clearing up the murky, snowy coldness that came seasonally in the form of Winter. For the heroes of Manhattan, this meant a rise in crime would likely be imminent.

And so, with strict vigilance and a watchful eye, a figure clad in a red and blue spider-themed suit made his daily appearance leaping from the rooftops with great agility and acrobatics. Letting out a loud cowboy interjection, the Web-head commonly known as "the Amazing Spider-Man" was clearly having the time of his life diving off the buildings as gravity took him toward the streets below. As with every web swing he ever made, he shot a thread of silky spider web-like substance from his webshooters, which latched onto the nearest building. Kicking his legs out, he swung over an oncoming tour bus, arching back up into the buildings.

"Good afternoon, New York! Today's forecast calls for a potential rise in crime waves followed by a storm of red and blue to wipe it out!" Spider-Man shouted, mimicking the nature of a news reporter.

With several web shootings coupled with flips and tricks, Spidey flew his way through the concrete canyons of the city en route for the nearest crime in progress. Eventually, he made his way onto the top of a tall building to take a breather. Despite working as New York's main crime fighter for a little over a year, Spider-Man still found his job rather thrilling since it meant digging into the corners of the city to root out petty criminals and solve bigger mysteries. Even so, he still considered himself an amateur sleuth.

One thing he wasn't amateur at was locating danger. Utilizing his sixth sense known as "Spider Sense", he scanned the horizons of the city when suddenly a security alarm rang nearby, alerting his Spider Sense to the dangers ahead. In response, Spidey launched himself from the building and tumbled through the city until he located the bank close by. Not wanting to take his precious time barging in, Spidey propelled his legs toward the nearest glass window, shattering it into a million pieces as he slid steadily onto the floor beneath. Naturally, his entrance garnered the attention of the quintet of criminals with guns and masks, both of which got Spidey's attention. Not to his surprise, they already cleared out the atrium by their own aggressive means.

"Spider-Man!" shouted a man in a ghoulish mob mask. "Couldn't stay away from our big heist now could you?"

"Whoa, hold on! Me? Getting up in your business?" Spidey retorted. "You're the one stealing the city's funds for all I care!"

The criminals fired their guns, the bullet shots echoing throughout the atrium and alerting the building's personnel. Spidey swiftly dodged the bullets by shooting a web line that allowed him to zip away toward and stick to the nearest wall for safety.

"Hold on a minute! Can't we talk this out crooks to spider?" Spidey pleaded jokingly.

"We only let our guns do the talking," the main crook remarked. "Sick 'em, boys!"

Firing a barrage of bullets at the Web-head, the crooks concentrated all fire on Spider-Man as he acrobatically swung off the ceiling and evaded each shot as he swung around them. Concentrating his webshooters toward them, Spidey fired back his own web shots at the criminals, striking them wherever he could - their guns, their masked faces, etc. - before dropping to the ground to take them on. Two of the now gunless criminals charged at Spidey, fists ready, and swung hastily at him, but he was too quick to just stand there and take it. After dodging their fists Matrix-style, he caught them both with his bare, or more accurately gloved, hands.

"Puh-lease, you shouldn't even wish to beat me in a fist fight!" Spidey quipped.

He twisted one criminal's wrist and dropped him to the ground before turning to kick the other one up toward the ceiling. Simultaneously, he shot strands of webs to web them both up in their respective positions. Before he could quip, more bullets from the leader's gun whizzed by him in what seemed to be slow motion, his Spider Sense forcing him to backflip away from them. He then proceeded to flip sideways, shoot a webline that attached to the criminal's gun, and pulled it, effectively yanking it away from him as he swung it around the room before letting it go. The firearm smacked another one of his mooks in his masked face so hard that he immediately fell to the floor, out cold from the impact. Just when the second to last criminal thought he was lucky enough to pounce on him from behind, Spidey clocked him right in the jaw before he could even lay a finger on him. Of course, because Spidey was so far away, the main criminal saw this as an opportunity to get away with his loot, which he left in a bag on the floor, scooping it up as he rushed away. But then Spidey and his ultra fast wall crawling abilities allowed him to get ahead and surprise him by hanging upside down from the ceiling.

"Hi, there!" Spidey said popping into view as he brought a webline down with him. "Could you hold this for me? Thanks!"

Spidey handed the crook his web, and, before he could react, he was hanging upside down from the ceiling, dropping his money in the process. Spidey then dropped from his webline and approached the dangling criminal whose mask was so grotesque that it was hard to imagine a face underneath.

"Seriously, what is with you guys wearing masks all of the sudden? That's my shtick!" Spidey complained as he yanked the guy's mask off revealing the face of a Caucasian male in his thirties underneath. "My webshooters better not be on the black market or I'll start suing those who give them out to lowlifes like you!"

"Careful what you say around here, Spider-Man!" the criminal retorted. "We wear them so that we don't get caught. And I'd have been lucky enough to not be recognized at the Hex Girls concert in a few days if it wasn't for you coming in and going all 'hero' on us!"

This comment caused Spidey to jolt back in shock over what he had forgotten earlier.

"Oh, man, the concert! I totally forgot!" Spidey muttered under his breath. "Um, I don't normally say this to your kind, but thanks for the reminder! And be sure to tell the police this was all courtesy of your Friendly Neighborhood Spider-Man while you let the blood rush to your head!"

Unwilling to listen to the criminal's comeback, Spider-Man sprinted out the way he came in and hurriedly swung back through the city en route for the suburbs of Queens where Midtown High was located. Although catching thieves just like flies was one of Spidey's biggest specialties, the one thing he lacked ambition in was catching things on time. And, with his school selling tickets to the upcoming Hex Girls concert in Manhattan, he fully resented the fact that he was about to miss the deadline or he would let his friends down yet again as with any typical civilian outing he had. Being super was one thing, but that was just an alter-ego to his high school student self commonly known as "Puny Parker", "Bookworm Parker", and "Stinky Pete" amongst other offensive nicknames the jocks came up with. Thankfully, though, he had friends who called him by his real name, Peter Parker, and what he wouldn't give to hear that they were proud of him for a change. Sure, being a junior in high school with open lunch had its benefits for his Spider-Man duties, but every so often he let it get in the way of quality time with friends to a point where they didn't seem to like him at times. And, since they were so excited about this Spring Break concert to the point of obsessing about it, he knew he wasn't about to let them down.

Eventually, Spidey made his way into an alleyway just outside the school. Remaining well out of sight, Peter changed back into his civilian clothes before making his way back onto the schoolyard and darting through the front doors. Not caring about who he would bump into, Peter sprinted his way into the cafeteria where he hoped the ticket booth - which was set to close at one p.m. the Friday before Spring Break - had miraculously still been in business for a while longer. However, Peter found himself utterly disappointed when he found the nerdy student council leader packing everything up.

"Sorry, my last ticket just sold and now we're closed," the student explained rather condescendingly. "You should really learn to grab them while you have the chance."

He walked away, leaving Peter to sit down in a nearby windowsill to sulk about yet another failure. Parker, you are a grade-A procrastinator, Peter thought to himself. They may as well throw you under the Hex Girls' tour bus soon as they arrive.

Just when he couldn't have thought of a more suitable punishment for himself, Peter had his thoughts broken up by the sight of his best friends standing across the way talking amongst themselves. The gorgeous redhead, Mary Jane Watson, stood turned away from him looking at him over her shoulder concerningly. Despite his enhanced hearing, Peter couldn't make out what they were saying the distance he sat away from them. Gwen Stacy, the blonde girl with a book in her hand, and Harry Osborn, the only nicely dressed guy in the group, were both uttering what Peter knew would most likely be disses for missing the ticket deadline. He didn't dare think about what they were thinking soon as they all turned around and started walking up to him at the same time.

"Miss your chance to get a ticket, Tiger?" asked Mary Jane noting his glum appearance.

"Isn't it obvious, Mary Jane?" asked Gwen somewhat sarcastically. "Peter's never gone first in line for anything in his life."

"Yeah, even I would go first to buy enough for all of you... if only my dad would share half his inheritance with me!" an insecure Harry promised clenching his manly fists.

Peter almost didn't have to think of a response to all these condescending comments from his best friends of all people. "Well, guys, I mucked up yet again," he ultimately said. "Laugh at me all you want, but I missed the ticket line like I always do."

"Relax, we're not here to put you down. We were just teasing you that's all," said Mary Jane leaning over to put her fingers on his chin. The warmness of her touch was enough to make him giddy.

"Thanks, MJ," Peter smiled. "But I don't think that's gonna help right now. What with-"

"Not to worry," MJ interrupted putting her finger to Peter's mouth. "Fortunately, my waitressing at the Silver Spoon gets me enough tips to buy tickets for just the two of us."

In her hands she held a black and red Hex Girls concert ticket that caused Peter's face to light up in amazement. Never in his young life had he thought anyone, even someone as kind as MJ, would go out of their way to buy him a ticket to somewhere after he missed his chance. Ever so friendly, she handed the ticket to him, himself grasping it firmly as he jumped up in excitement.

"No way! I mean, you really shouldn't have! Thanks, MJ!" he hugged her tightly, spinning her around as her legs popped. The two of them were getting very close and it very much warmed Gwen's heart seeing them this way.

"Don't mention it. I'd say you're pretty fortunate to have those like us around. And don't take it too personal if we tease you like that. Consider it tough love," MJ assured him.

"You had me at 'tough'," Peter responded, giggling. "Besides, I'd never know what to do… without you guys around. Thanks for keeping me in check!"

This comment made MJ smile, showing all her gratitude at once.

"Anything to get you thinking about the best in life, Pete!" Gwen commented, trying not to be sarcastic for a change.

"I second that emotion!" Harry chimed in.

This sort of exchange was pretty typical for Peter and his friends. They generally loved to pick on him, but, at the end of the day, they were still his friends. Knowing what they meant to him on a regular day, he would likely never trade them for the world.

Elsewhere, in the small town of Coolsville, Ohio, the residents had decorated the place to the max with Hex Girls-related apparel; from darkly colored flowers lining the floral shops to the resident's American flags hanging next to Hex Girls flags, people were going crazy as it was the band's last night in town on their Spring Break tour. Their presence in the city invited massive support due to their renowned status. However, with that much love also came hatred.

The last few days had seen a mysterious, ghostly motorcycle rider sweep the streets with ghostly smoke and bombs in an effort to stop anyone, superfans and the like, from prancing their way to the concerts presumably out of hatred for the band itself. Dubbed the "Road Rager" by many, the man had an appearance similar to that of a comic book supervillain - or antihero for all the comic fans cared. As much a mystery as it was to the town's mayor and sheriff who were too brain-dead to investigate the matter at hand, the stakes were nothing against the likes of Mystery Incorporated - the town's renowned, yet somewhat reviled, mystery-solving super sleuths. They had been on the case since the whole ordeal started and, despite them having school, they managed to excuse themselves early to go track the supposed ghost. In an alleyway, their brightly colored minivan, the "Mystery Machine" sat hidden out of sight while they did their own fieldwork. The van's intellectual computer operator, the brightly dressed, glasses-wearing Velma Dinkley, had been tapping into the location of the Road Rager's motorcycle, tracking him like an eagle to its rodent prey.

"I've got the Road Rager's whereabouts tracked through real time satellite readings. According to this radar I've constructed, the Hex Girls' tour bus is headed this way too. If we can catch the Road Rager, they'll have the safest arrival we can offer," Velma stated as she radioed in the group. She then turned to her redhead pal, Daphne Blake - the team's moral support and main funder - who was wearing a Hex Girls shirt over her all-purple attire consisting also of a green scarf. She had been sitting right outside the van in preparation to act as bait - a role that generally belonged to the group's most clumsy members. "Daphne, be ready to act when he comes!"

"Got it! I hope to remember my lines," Daphne responded, giving a thumbs up to Velma whom she trusted as a friend.

"Trust us when we say you won't get hurt," Velma added reassuringly

With a smile Daphne then proceeded out of the alleyway, stopping next to the team's buff, blonde, slick-haired leader and trap builder, Fred Jones. He was knelt in a position to set off an elaborate trap to catch the ghost with. "Freddy, you promise you won't let me get hurt either?"

As usual, Fred blushed as a result of Daphne talking to him, not knowing half the time what to say to her. "Well, as long as nobody sets off the trap prematurely, it should be fine!" This caused Daphne to become a little disconcerted. She had full on expected a romantic response from Fred - whom she openly admired - but, since he had a hard time expressing his feelings, she faked a smile, deciding to let this one pass for now as she turned to make her way onto the empty street. Fred radioed into the team's biggest amateur and his dog who were stationed atop a nearby two-story building. "Shaggy and Scooby, this is for you," Fred said, causing them to get their heads out of their box of Scooby Snacks and pay attention. "Do not, I repeat, do not set off the trap before I give the signal. Got it?"

In response, "Shaggy" - real name, Norville Rogers - in all his dusty blonde hairiness proceeded to grab his end of the rope with "Scooby" - real name, Scoobert Doo - assisting to give him a little extra muscle since, on their own, they had next to none. "Like, that Road Rager won't know what hit him, Fred! You hear that Scoob?"

"Reah, Raggy!" Scooby exclaimed in his misunderstandable dialect of beginning some words and most names with the letter "R" for some odd reason. "I'll keep a sharp eye out for him!"

"That's my boy, Scoob!" Shaggy said petting his great dane of a dog - without whom he believed he would be nothing. The two were practically inseparable and were part of the reason their gang held together like pieces of paper glued together.

In the distance, the Road Rager's motorcycle came roaring as dark exhaust poured out of it and into the air, nearly masking his flaming, ghoulish figure in mystery. As Daphne got into position, she strutted onto the street, flaunting her fake Hex Girls superfan persona as she tossed her hair around. Despite his need to fixate on traps, Fred was easily breath taken by Daphne's act that he nearly lost focus. "Oh, I can't wait for that Hex Girls concert tonight!" Daphne shouted rather fakely as the Road Rager neared her position. "I'm gonna have so much fun with my friends and we're gonna sing every song we know like the back of our hands! It'll be such a blast!"

Whilst Daphne acted quite well for her fake role, a couple pigeons landed nearby Scooby and Shaggy's position atop the roof to peck at the breadcrumbs from sandwiches they ate earlier. Distracted, Scooby snarled angrily at these strangers of birds and pounced from his position to chase them away.

"Scooby-Doo!" Shaggy shouted desperate for him to come back, but it was too late.

"Now, gang!" Fred shouted, pulling his end of the rope of which he felt no tug at the other end. Without Scooby and Shaggy's support, Fred was left to direct the rope by himself and had nary a clue how to improvise. Thinking smart, he decided to whip it into action and wound up causing Daphne to slip and fall onto the asphalt just as the Road Rager was within range.

"Down with the Hex Girls and their pathetic fans!" the Road Rager's ghostly voice shouted menacingly as his motorcycle was about to run Daphne over. Instinctively, Daphne rolled out of the way, screaming as she thought for a moment he had run her over. Next thing she knew she was still alive and looked up to witness the Road Rager pass her by. "What the-" he exclaimed, confused and unaware that, despite the failed first phase of the trap, he was still riding right into danger. Soon as he turned back to face the road, he realized he was riding right into a standard trap of a net. Before he could apply the break, however, the net wrapped him up with his motorcycle, the tires continuing to roll until they stopped, leaving him to squirm about in the net with no way out.

As Mystery Inc. resigned from their positions, they approached the ghostly rider, relishing their unexpected victory despite the failed trap. "Great job, gang! Another ghost captured!" Fred exclaimed in celebration. "Now, let's see what unoriginal phony decided to terrorize the town today."

Fred pulled off the ghostly rider's fake flaming mask, revealing him as their old, white-bearded school music professor, Charles Lockhand. "Professor Lockhand?!" they all exclaimed in unison.

"The same guy whose been playing us haunting classical tunes in music class!" Velma boasted, knowing her guess was the most correct of them all. "Shocking!"

"Okay, I'll admit it, you kids are very clever to catch me like this," the professor humbly admitted his own defeat.

"And here I thought you were the most musically sensitive man at Coolsville High!" Daphne pointed out, upset that her favorite teacher would terrorize the town like that. "Now why would you do such a thing?!"

"It all started when I planned to host a classical music seminar," Lockhand proceeded to explain. "I sent out invites to everyone in school thinking there would be no other musical event in town to interfere with my own, but then those dreaded Hex Girls announced their arrival in Coolsville the same week I had planned for it to take place. Next thing I noticed, everyone - every music fan and lover - turned down my invitation to attend some silly modern music concert that no one realizes is just as desensitizing as cell phones these days. And so, I felt rejected; like no one would ever appreciate our musical roots in classical tunes. And then, one day, I came across my old motorbike, 'Ms. Priscilla", in my garage. Though she aged horribly into a more ghostly appearance, she worked fine and gave me incentive to hatch a plan to deter everyone away from those stupid Hex Girls. Utilizing my knowledge of special effects from my days in Hollywood, I donned an old mask that gave me the appearance of a ghostly motorcyclist that would disguise my rampages through the city. My intent was not to harm innocent bystanders, but merely discourage them from attending the concert knowing they weren't safe out there."

Lockhand had been talking for such a long time that he barely even noticed the cops had arrived to cut him down and cuff him. "I was about to win everyone back to my musical seminar; show everyone the wonders of our true musical roots instead of that trash you teens call music!" Lockhand continued to rant as he was being shoved toward the police car. "And I would've gotten away with it too if it weren't for you reckless students of mine and your musically inept canine!"

Finally, the cops got into their car, flashing their red and blue top lights as they drove away the ranting teacher. Staring at their most recent catch being driven away, the Mystery Gang turned to face each other. "Well, as Fred would say, 'another mystery solved'!" Velma said, honoring Fred's traditional catchphrase.

"Thanks, Velma. That really helps after my traps end up not working the way I hoped," Fred commented, giving Shaggy a somewhat demeaning look, the latter of whom seemed shocked.

"Like, sorry, Fred. Scoob here got distracted by pecking pigeons leaving me with, like, little manpower," Shaggy explained.

Scooby hung his head in shame, whimpering. "Sorry, Shaggy," the dog said audibly. "My leftovers were being sabotaged."

"Well, maybe next time we shouldn't eat so much bread when scouting outdoors," Shaggy suggested. It was the least he could do to show he at least knew how to improve his approach.

Upon hearing and accepting his explanation, Fred turned away from them towards Daphne whom he felt sorry for tripping earlier. "Daphne, I'm really sorry I tripped you instead and, in turn, nearly got you killed and-"

Daphne hushed Fred by putting her dainty finger to his lips. "It's nothing you did, Fred. Maybe it's about time our team developed a little more backbone - and had less distractions," she added as she gave the inseparable pair a condescending glance for their incompetence.

"Maybe," he said somewhat in agreement. "But it's not like we can just kick them out. We're all friends here and we stick together until the end no matter what."

"Right. Still…" Daphne trailed off soon as the gang turned to witness yet another scene unfolding before them. A giant, flashy tour bus rolled up beside them, the photos of the Hex Girls pasted on the side filling their view as passersby screamed with excitement over the bands' presence. The bus then screeched to a halt directly in front of them, indicating they were here to see them. From the side door piled out the three members of Hex Girls in their eco-gothic attire to greet their local saviors. Velma's jaw dropped upon their entrance to the scene.

"Hello again, Mystery Inc." stated the band's black-haired with red highlights lead singer and guitarist Sally McKnight, commonly known as "Thorn" amongst her fans. The dress she wore complimented her hair well and really brought out her look into the impending sunset. This wasn't the first time she and the band had a run-in with the gang, especially since they were most frequently attacked by ghoulish figures.

"Great job saving us back there," complimented Dusk, the blonde, pig-tailed, and feisty back-up singer and drummer, who had surprisingly softened up for a change to tell them what a good they did them.

"It was about time someone caught that Road Rager. Our attendees were declining as we knew it, but hopefully tonight's better," said the darker-skinned, red-haired keyboardist, Luna, who, like her colleagues, craved attention and more numbers at their concerts.

"Hey, like, what can we say? It was no big deal!" Shaggy said in an attempt to cover up his clumsiness, which they hadn't noticed yet, but could potentially find out.

"Ohmygosh, ohmygosh, ohmygosh!" Velma exclaimed, hyperventilating in the presence of her favorite band. Even though she met them several times, seeing them in person still gave her butterflies. "I can't stress enough how great it is to see you again! And, since we saved you for the umpteenth time, you have to let us know what more we can do! Maybe tour with the band? Be with the band? Be in the band?!" She squealed in excitement as Daphne put a hand on her shoulder to cool her down.

"Erm, Velma's a little excited as always," Daphne reiterated. "But if there's anything more we can do just give us a call and let us know." Though Daphne adored the Hex Girls as much as everyone else, she wasn't a superfan like Velma whose room was lined with Hex Girls merchandise from posters to music boxes and spare pencils she kept in case she ran out.

While they were used to Velma acting this way, being in the band still wasn't an option as, like Scooby and Shaggy, the band deemed themselves inseparable for life. And so each member gave it a moment to ponder their options. "Well, you did save our hides yet again. And, catch this, our next stop is New York," explained Thorn. "This town may have its fair share of crooks in masks, but that city's crawling with many more. Mad scientists with electric powers, spider men, you name it. So, if you want, come to New York with us and be our bodyguards."

"That sure sounds like a nice offer, but don't you already have a bodyguard?" Fred added.

"Well, our security guard, Quentin Beck's, got a lot under his belt - both figuratively and literally," Luna explained. "But you guys are the real mystery busters around here. If you can stop road ragers from hurting our fans you can surely stop a scientific freak accident from kidnapping us for experimentation."

"Come on, Fred, please say yes!" Velma butted in, giving him puppy dog eyes he could never resist.

Fred gave Velma a knowing glance in return. "If it wasn't for us having Spring Break, I'd say 'no'. Otherwise, we have school off for this week so… Yes!"

"Yes! Woohoo! Thanks, Fred!" Velma hugged him, popping her leg in appreciation before she backed off, realizing she could potentially make Daphne jealous with that maneuver - Velma had no feelings for Fred after all.

"You hear that, Scoob? Like, she said 'Spider-Men'!" Shaggy leaned in to whisper excitedly to his dog of a best friend.

"You mean like that one song, 'Spider-Man, Spider-Man. Does whatever a spider can!'?" Scooby sang in a relatively off-key tone.

"Yeah, like, I've always dreamed of going to New York to actually, you know, meet the guy," Shaggy said, lost in his own bliss. "Mostly I've done nothing, but idolize him in the comics, cartoons, and whatever else that's Spider-Man out there. Like, if I could, I'd have as much Spidey merch as Velma does Hex Girls stuff."

"Really, Shaggy?" Velma sassed. "A Spider-Man is nothing compared to these… these… musical goddesses! Seriously, you don't know how much you rock!" She said kneeling down as she let out a fangirl scream causing everyone to cringe from her overly excited outburst.

Ignoring her, Fred turned to ask her a question. "When do you girls leave?"

"Tomorrow morning, first thing," said Luna. "New York's a hotspot for bands like us so we ought to show up on time."

"Jinkies!" Velma exclaimed. "We'll all be ready bright and early, won't we gang?"

Behaving silly like they usually do, Scooby and Shaggy thought about the decision for a brief moment. "But, of course!" Shaggy finally said, stumbling somewhat. Saturday was usually sleep in day for him and Scooby, but they could at least try to make an exception.

"In that case, I'll be on it with my best traps in case something goes wrong. But since New York is often protected by big name superheroes, I'm sure there won't be too much trouble!"

"I wouldn't count on that if I were you," Daphne said under her breath, rolling her eyes. Fred always dreamed of the perfect trap and mystery solving case, but it was almost as if he couldn't see the perfection that was her standing right in front of him the whole time. She was, after all the most danger prone of the group and, if she wasn't that enough in Coolsville, surely New York would be no different. Still, as the gang put their hands together to declare undying teamwork, they all remained hopeful that whatever came their way wouldn't put a damper on their team as a whole.

Thanks for reading my first real story chapter. I am hopeful you all will enjoy as the mystery unfolds with Scooby-Doo and Spider-Man crossing paths like never before!
