Jayna was walking with Justin. Courtney also walked by, and 'accidentally' bumped the Female Wonder Twin.

"Hey!" Jayna glared.

"Oops," Courtney replied. "Sorry, didn't see you there."

Jayna glared as she soon stood up before bumping Courtney back. "Whoops!"

"Hey!" Courtney glared.

"Oops, sorry, didn't see you there." Jayna smirked.

"Why did you let Courtney Garcia come along?" Brianna complained to her friends from Mystery Inc.

"Sorry, Bri, we didn't know that she wasn't your friend." Fred defended.

"Well, she used to be nice, until Total Drama Action came out," Brianna replied. "Since then, she's acted like a bratty little kid."

"Ugh, don't remind me of Total Drama Action." Justin muttered.

"I hated that season when you showed it to me." Jayna told Justin.

"Same here," Zan agreed. "A bit weaker than Total Drama Island. Though, I guess it's better than Total Drama All-Stars."

Everybody shuddered about that season.

"I never liked Total Drama All-Stars, but my favorite might be Pahkitew Island." Daphne said.

"You liked Pahkitew Island?" Fred asked her.

"Eh, only for two contestants," Daphne replied. "My favorites were Sky and Samey."

"Oh... Okay." Fred said.

"Why?" Daphne asked. "Didn't you like Pahkitew Island?"

"Well, it was all right, but my favorite is Revenge of the Island," Fred smiled in memory. "Because Anne Maria was so ho-"

Daphne glared at her boyfriend, cutting him off.

"Uh... Wholesome..." Fred smiled nervously. "I mean, she was an interesting contestant... Anyone's better than that Staci girl, I guess."

"Like, has anyone else started watching Cartoon Cartoon Island?" Shaggy asked.

"I have," Velma replied. "I'm still on episode six though."

"I hate to break this up, but we should really focus on what Batman wants." Brianna said to the others.

"Sorry, Bri," Fred replied. "Guess we got off topic."

"We gotta get back to Gotham City," Batman told the others. "We'll meet you there, let's go."

Martian Manhunter and Detective Chimp followed the Dark Knight, but Shadow Wolf stayed behind.

"I'll see you at Gotham." Justine told Shadow Wolf.

"See you there." Shadow Wolf replied mysteriously as always.

Justine and Shadow Wolf kissed each other on the lips and hugged each other.

"Stay beautiful." Shadow Wolf said.

"And you stay handsome." Justine replied.

The two smirked to each other before they soon went off to get down to business. And with that, they soon made their way into Gotham City.

The next day, something was going on at Gotham City Bank. Batman and Shadow Wolf were fighting against The Riddler and his goons. One goon tried to shoot at them, but was soon knocked out by a Baterang. Shadow Wolf looked over as Batman fought the goons and they could hear a helicopter not too far off down the road.

"Sayonara, my Masked Mutton Heads!" The Riddler mocked as he escaped.

"Not so fast, you malignant mind boggler!" Batman glared.

Shadow Wolf used her tendrils to pull down the Riddler to the ground.

"We've danced this dance before, Riddler," Batman told his enemy. "It always ends up with you licking your wounds in a padded cell at Arkham Asylum."

"True, you beat me two-on-one, Batman and Shadow Wolf," The Riddler smirked as he put his hat back on once he could stand up. "But riddle me this: When is a villain like a mathematician? Answer: When it multiplies!"

The goons soon came right down behind their boss as The Riddler laughed. Two whips then swung by a lamp post and stood by the Riddler: it was Catwoman and Alicia, who wore a purple bodysuit with a tail, cat ears, a mask with silts, and gloves with claws.

"Did someone mention a dance?" Catwoman smirked. "This is my niece, The Seductive Cat, she loves to dance."

"You again..." Shadow Wolf narrowed her eyes toward Alicia.

"Up for a little game of cat and mouse?" The Seductive Cat purred to Shadow Wolf.

"Yeah, only this time, it's Cat vs Wolf." Shadow Wolf glared.

"Meow~" The Seductive Cat smirked.

Killer Croc then came out of the sewer and stood next to the Riddler.

"I'm gonna make a nice Bat and Wolf Gumbo outta you!" Killer Croc smirked at Batman and Shadow Wolf.

"Clever, but we've anticipated this." Shadow Wolf smirked at the villains.

"We brought some additional allies of our own." Batman replied.

"Outrageous!" Aquaman proclaimed as he appeared next to the Dark Knight.

"Aquaman, Question, thank you for your assistance." Batman thanked his fellow heroes.

"Could I ever refuse a call from you, Batman?" Question replied.

"Crab Cakes!" Aquaman complained. "You brought him? He's annoying with all those duced questions!"

"And how are you, Aquaman?" Question asked.

"See?!" Aquaman pouted. "He really creeps me out..."

The villains looked at each other in confusion.

"Oh, have at thee, you reptilian rapscallion!" Aquaman glared at Killer Croc before storming toward him.

Shadow Wolf glared at Seductive Cat and decided to handle her. Catwoman was going to fight Question and Batman was going to handle the goons and the Riddler.

"Meow~" The Seductive Cat purred. "Shall we dance, handsome?"

"You wish." Shadow Wolf scoffed.

Seductive Cat pulled out her whip and grabbed Shadow Wolf with it. Shadow Wolf glared while trying to break out of the whip.

"Ooh, Kitty's got claws~" Seductive Cat smirked to Shadow Wolf.

"And the wolf's got bigger claws." Shadow Wolf replied before she turned into a shadow and escaped from the whip.

"Huh?" Seductive Cat looked around. "Where'd you go?"

Aquaman soon threw Killer Croc toward Seductive Cat to knock her down. "Huzzah!"

"Gee, thanks, Aquaman." Shadow Wolf deadpanned.

"No problem, my fine wolf friend." Aquaman smiled.

Shadow Wolf rolled her eyes and face-palmed.

"Meeting, not party." Batman told Aquaman after punching a goon.

Question was fighting with Catwoman, dodging the claws, unfortunately getting claw marks on the sleeve of his trench coat.

"Aquaman, use your Hydrokinesis!" Batman called out.

"What's that gonna do?!" Shadow Wolf asked as she pinned down Seductive Cat and punched her.

"My what the what?!" Aquaman asked.

"Your water controlling powers..." Shadow Wolf groaned.

Seductive Cat smirked to Shadow Wolf and kissed her on the mouth just to taunt her.

"What the?!" Shadow Wolf glared. "Did you just kiss me?!"

"Hmm... You're strong for a man~" Seductive Cat smirked. "So big and handsome~"

Shadow Wolf soon spun around in a tornado with Seductive Cat and threw her into the water.

"Yes, my hydro..." Aquaman muttered under his breath, and he soon summoned water in his command to attack the villains and then Batman pulled out a control and threw it into the water, shocking the villains, and knocking them out.

"Safe to say, that's a wrap." Question commented.

"Then, to the Mystery Anaylsis meeting." Batman replied.

"Outrageous!" Aquaman called out. "Let's get going."

"It's secret invite only, Aquaman..." Shadow Wolf told him.

"I'm afraid she's right," Batman agreed with his goddaughter. "You're not a detective."

"Not a detective?" Aquaman replied. "Why, I'm a whiz at sleuthing underwater currents!"

"That's social under fee, not crime scene investigation." Batman scoffed.

"Plus, I can identify 900 species of fish on sight alone." Aquaman continued.

"That's ichthyology." Shadow Wolf pointed out.

"Precisely!" Aquaman replied. "And who's better at detecting those nasty, hard-to-reach volcanic fishes, eh? Me, that's who!"

"Again, oceanography," Shadow Wolf rolled her eyes. "Why don't you go have a Krabby Patty with SpongeBob Squarepants while you're at it or help Princess Ariel get legs so she can marry Prince Eric?"

"But thanks for mopping up." Batman added before he went to his batmobile and drove off as did Question who drove off with his own car.

"Hey, don't you wanna help me?" Aquaman asked as he looked at Shadow Wolf who was going to the alley.

"Sorry, I can't, see, I got this thing called a life." Shadow Wolf said before going to join Batman in the Batmobile. She then went into the alley and disappeared into the shadows.

"Some pals, leaving me to do all the work," Aquaman muttered before he then summoned an octopus. "Edgar, do all the work. Detectives only, hmm?"

Meanwhile, later that night, the gang is arriving at Gotham City to come to the meeting.

"So, dude, there will be dinner served at the meeting, correct?" Shaggy asked.

"You just cleaned out a truck stop mini mart on the way here." Justine reminded him.

"No, I saved one box of cookies for later!" Shaggy smiled before taking out a box. "Which is now..."

Scooby then took the cookies and ate them.

"Like, dude, no fair!" Shaggy complained.

Scooby giggled innocently to his best friend.

"You know what's the real mystery here?" Paulina rhetorically asked the others. "Batman and Shadow Wolf themselves, I mean, who are they, really?"

"Under those masks, they could be anyone." Fred shrugged as he drove the Mystery Machine.

"Technically not anyone," Velma said as she took out a notepad. "Given Batman and Shadow Wolf's height and proportions, combined with the necessary financial means, I've narrowed down to Gotham's 10,000,000 citizens down to a mere 6,052, though Shadow Wolf still remains a mystery even to me."

"Maybe you could ask them yourself, cuz we're here." Fred said as he pulled into the alley.

"But which door is it?" Brianna asked. "There are dozens."

"No sign of a key hole or a doorknob." Trent added.

"Fred, wait, stop the van!" Jayna called out.

Fred looked to her and soon stopped the van.

"'Say My Lass, A Myth Forgotten'?" Courtney read aloud from a door.

"Man, that is really bad haiku," Shaggy commented. "Or a good haiku? I could never tell."

"No, silly, it's not a poem, it's an anagram." Justine told the cowardly teen.

Daphne wrote down the words that was on the door unscramble to Mystery Analysts of Gotham. "Ta da!"

"Mystery Analysts of Gotham?" Fred asked.

Shaggy and Scooby looked confused.

"Word Jumbles, just make those long mile by mystery miles fly by." Daphne smiled sheepishly to the others.

"And look!" Zan pointed out. "There's a gap in the bricks!"

Fred got out of the van and pulled out the card and put it in the gap. The gap beeped and the door was opened.

"Awesome!" Paulina beamed.

Fred came back into the van and drove them through the open door.

There was more than one door they had to drive through.

"How many doors does he even need?" Courtney asked.

"Shh." Justin told her.

"What, Justin?" Courtney panicked. "Did you hear something?"

"No, I just wanted you to be quiet." Justin told her.

"Okay, Justin, whatever you say." Courtney replied.

"Meaning be quiet right now." Justine told her.

Courtney glared to her and Justine glared back, but had a small smirk.
