Scooby Doo and the Reikai Tantei

Part 1- The Attack of the Werewolf Demon and Meeting Yusuke and Kuwabara

The Mystery Inc gang is still in Japan visiting after their friend Miyumi left for her own adventure. They decide to keep visit more sites in Japan. They walk to the train station and they take their suitcases inside.

"Alright, gang, we're going to more places in Japan." Fred says excitedly to the rest of Mystery Inc.

"Like, me and Scoob we'll eat more Japanese Scooby Snacks." Shaggy says excitedly eating the Japanese Scooby Snacks.

"Reah." Scooby says excitedly in agreement also eating Japanese Scooby Snacks.

"I'm glad, Miyumi gave us direction to the next town." Daphne says excitedly with the directions that Miyumi gave her.

"We'll have some fun too." Velma says excitedly.

The train starts to leave and they soon leaves off to next town. What they didn't know a pair of eyes are watching them from a distance. It is a werewolf demon. It has gray fur with silver like tone near its ears and muzzle. It laughs sinisterly and soon began to follow Mystery Inc. Meanwhile in Spirit World, Koenma is aware of the werewolf demon presence in Japan and gets Botan to his office. Botan comes to office.

"Botan, we have a situation." Koenma says seriously.

"What is it, sir?" Botan asks seriously.

"A werewolf demon is on the loose in somewhere near Tokyo. It is following a group of teens with a dog from America."

"Ok, I'll get Yusuke, right on it."

"Botan, I have feeling things are about to get weird on Yusuke and the others recently the dog from America just got his statue for being famous."

"What's the dog's name, sir."

"Scooby Doo!"

Meanwhile Mystery Inc gets off the train in Mushiori City. The werewolf demon that followed them also gets off. Mystery Inc. looks around the city. The werewolf demon continues to follow them.

"Look, Scooby, more Japanese Scooby Snacks." Shaggy says excitedly looking at the vending machine with the Scooby Snacks.

"Scooby Doo!" A Japanese girl says excitedly hearing Shaggy say Scooby's name.

Soon more Japanese girls crowd Scooby and Shaggy. The girls are taking pictures with Scooby. Shaggy just laughs knowing Scooby is enjoying his new found celebrity in Japan. The Werewolf demon sees Scooby in his sights but he waits for a chance to pounce. It is nighttime with a full moon in Japan and Scooby and the gang get to a hotel. Shaggy and Scooby are in their room.

"Hey, Scoob, can you order room service to get us some Japanese Scooby Snacks. I'm staving." Shaggy asks Scooby.

"Rok." Scooby replies to Shaggy.

Scooby goes to the phone and orders the Japanese Scooby Snacks with much difficulty. Finally there is a knock on the door. Scooby answers it and he sees the Japanese Scooby Snacks but whom sees deliver it is not room service but the werewolf demon.

"Rikes!" Scooby yells out as he hid in the cover with Shaggy.

"Like, what's wrong, Scooby…Zoinks!" Shaggy screams out seeing the werewolf demon.

The werewolf demon pounces on the bed but Shaggy and Scooby run before he gets there. They soon run out the door and the werewolf demon follows. Shaggy and Scooby goes into Fred's room.

"What's wrong, guys?" Fred asks seriously seeing Shaggy and Scooby in his room.

"There's a werewolf in our room." Shaggy answers scared with his teeth chattering.

"A werewolf?"

"Reah, a rerewolf." Scooby says also scared with his knees shaking.

"Ok, I'm coming." Fred says as he, Shaggy, Scooby left Fred's room at the same time Daphne and Velma came out as well.

"What's going on we heard screaming." Daphne asks the boys.

"There's a werewolf in our room." Shaggy says scared to Daphne and Velma.

"A werewolf?' Velma says skeptically not believing what Shaggy said.

"Look," Shaggy says as he opens he and Scooby's hotel room and there was no werewolf in their room.

"There's nothing here." Fred says looking into the room.

"But…But…"

"Let's go back to bed and we'll…" Fred starts to say as he and the others heard growling.

"Zoinks! The werewolf!" Shaggy screams as he and the others start running away from werewolf demon.

The werewolf demon chases after Shaggy and Scooby. Shaggy and Scooby run faster. The werewolf demon starts to glow as the moon hits him making him stronger and faster. Shaggy and Scooby are trapped in the corner. The werewolf demon comes closer and suddenly he knocked over mysteriously. The werewolf demon gets up and he sees two teens that Shaggy and Scooby didn't recognized. One had black hair that is slicked back with bangs in the front of his forehead he wore a green school outfit and the other teen had orange/ginger hair that is in the pompadour style with three bang on the front he wears and outfit similar to the first teen but instead of it being green it was blue.

"Are you two ok?" The first teen asks seriously.

"Like, yeah, we are like who are you two?" Shaggy asks the two teens.

"I'm Yusuke Urameshi." The first teen answers.

"Kazuma Kuwabara." The second teen answers.

"I'm Shaggy and this is Scooby Doo." Shaggy answers pointing to himself than to Scooby

"Rello." Scooby says waving.

"What did he say?" Yusuke asks in shock hearing Scooby.

"He said hello." Shaggy answers telling the two boys about Scooby.

"Your dog talks?" Kuwabara asks in shock also hearing Scooby.

"Yeah." Shaggy answers like its normal.

"I've seen everything." Yusuke says in shock.

The werewolf demon wakes up and growls and charges at Yusuke, Kuwabara, Shaggy and Scooby. The werewolf demon pounces and it hits Scooby so hard that the glow from the werewolf demon hits Scooby's dog tag causing its powers to be absorbed into Scooby unknown to Yusuke, Kuwabara and Shaggy. The werewolf demon starts to transform into a regular wolf. The werewolf demon then grabs Shaggy with his fangs. He run causing Yusuke, Kuwabara and Scooby to chase after it and they soon heard more screams from Fred, Daphne and Velma. When Yusuke, Kuwabara and Scooby get there, there is scratch marks on the wall and a note in that said: "Scooby Doo, give back what is mine or your friends are going to be my next dinner you have until two full moons from now!"

"What the hell does that mean?" Yusuke asks confused seeing the note on the wall.

"Ri Ron't Rnow!" Scooby says confused looking at the note.

"What did he say?"

"I don't know, Urameshi." Kuwabara answers confused not understanding Scooby as well.

"We got to get Scooby back to you know where." Yusuke says serious to Kuwabara.
