I am a retro fan of Scooby Doo. If your a fan of the classic Scooby Doo mysteries then a big shout out to you. Read and review. Oh and before I forget I am NOT abandoning my other fics, idea block on others and I will get on the chapters on the others.

Shaggy and Scooby's House

It was dark and foggy out when a tall dark figure was outside a house with a green roof and brown bricks.

This house seemed to be the one he was searching for. "Hehehe, 'Shaggy R. and Scooby D.' I know these two are going to be in one heck of a ride." The figure chuckled fiendishly as he walked over to the door.

Inside the house was a tall skinny man with brown hair and a small goatee. The man was wearing a green short sleeve shirt, and brown pants. This is Shaggy Rogers of Mystery Inc.

There was also a Great Dane with brown hair, black spots and wearing a four sided diamond shaped dog collar with the initials 'SD' engraved on it. This is the infamous Scooby Doo of Mystery Inc. and best friend of Shaggy Rogers.

"Hey Scoob, do you feel up for a double decker chocolate tuna sandwich?" Shaggy asked Scooby. "With hot sauce and ghost peppers dunked in caramel?" Scooby asked his friend.

As the two headed towards their kitchen the front door bell ranged and the duo headed over to it. Shaggy opened up the door and was greeted by a terrifying sight.

It was a tall cyan glowing well built man dressed in a black suit, with a black and red cape, with a bat tie. The man wore two green gloves with red eyes and cross stitched 'mouths'. The figure had a skeleton head with a top hat with a pumpkin emblem on it. The figure had red eyes in its black sockets.

"Hi are you going to invite me inside?" the man asked tauntingly. Shaggy just slowly closed the door on the man. Shaggy then turned to Scooby with a scared expression.

"RUN SCOOB!" Shaggy yelled as the man bursted through the door. This time he had a look of annoyance possibly due to Shaggy's gesture.

"Foolish cowards, I am the Nightmare Master! Prepare to face one of your old foes. Black Knight seize these two fools!" Said Nightmare Master as his servant appeared out of the fog. Shaggy and Scooby yelped out of fear as they remembered when they first met the Black Knight Ghost.

The Black Knight Ghost was a medieval knights suit that was made from a black metal. He had a red plumage on the the top of his helmet. The Black Knight has yellow glowing eyes and was wielding a medieval sword.

"So we meet again knaves," The Black Knight said as he stepped closer to the two. Shaggy remembered that the last time that the team faced the Knight, it turned out to be a man in a mask, or helmet in the Black Knight's case.

Shaggy grabbed the Black Knight's helmet and with a string tug he took it off, and this time there was nothing inside it. No man, woman, child on stilts, not even mechanical parts to signify that it was a robot, for once the monster was real.

The Black Knight reclaimed his helmet and returned it back on to his body. The Black Knight chuckled evily as he turned his attention to the two. Shaggy and Scooby Doo were caught by the Black Knight before they could escape.

"Zoinks! Like help us!" Shaggy said as the phantom knight brought the two to the Nightmare Master. The Black Knight grumbled at the two cowarding males.

"Hehehe, Looks like your little friends are not going to save you. Don't worry about them, they'll join you two soon after we're through with you!" Nightmare Master cackled as he petted Scooby's back.

The Nightmare Master laughed evily as he motioned the Black Knight to bring the two with them.

"You two shall soon know the true meaning of the word fear. My loyal servant throw those two into the abyss. Muhahahaha," said the Nightmare Master as he and the Black Knight were above a cliff.

The Black Knight threw Shaggy and Scooby down to the bottom of the cliff. However as the two were halfway down a strange light flashed and taken the friends away to another dimension.

Old Equestria Castle

An Alicorn with a blue coat of fur, dark blue mane and tail, a lunar pattern on her hind legs, and a scarf with the same pattern was walking around what used to be her and her sister's home. This is Princess Luna of Canterlot.

"I still can't get over the fact that I did this. How in the world did I become Nightmare Moon and have no memories of the forces? Huh?" Luna said before a light appeared and Shaggy and Scooby Doo landed near her.

"Ouch like what happened? Uh is that a what I think it is?" Shaggy asked before he and Scooby did the normal reaction anyone would have if they seen a mystical creature. The two fainted on the spot.

"I guess my dear sister should take a look at this, I know Lyra Heartstring would go insane." Luna said as she used her magic to pick up the two.

In the shadows a dark green shadow with red eyes and a red mouth was watching the three before disappearing to it's master. This is going to be one crazy adventure waiting to happen.

Authors Notes: there we go Shaggy and Scooby Doo has been thrown to Equestria literally that is. Here's a fun fact for you; the Black Knight Ghost was the very first villain Scooby and the Gang encountered.
