Scooby - Doo is probably the most popular overall. His love for food and his unique way of speaking make him a fan favorite. Velma is also popular as she's the brains of the group. In fanfiction, she might be the one to figure out the secrets behind the 13 ghosts. Fred, with his leadership skills, can also be a central character. Writers might focus on how he leads the gang in their encounters with the ghosts. And some of the more unique - looking ghosts, like Zomba or Maldor, can be popular as they offer a lot of creative potential for writers to explore their personalities and powers in fanfiction.
Ash from Pokemon and Shaggy from Scooby Doo are also commonly paired. Both are a bit naive in their own ways and are always ready for an adventure. They could share their experiences of traveling and facing challenges, whether it's in the Pokemon world or solving a Scooby Doo mystery.
One popular plotline is when the pups go on a mystery-solving adventure in a spooky old mansion. They encounter strange noises and things that go bump in the night. Another is when they have to solve a mystery involving a missing treasure. And sometimes, there are plotlines where the pups have to deal with a new character who is causing trouble in their town.
I think Velma is an interesting character to write about in 'A pup named scooby doo' fanfiction. She's the brains of the group, so you can write about her coming up with brilliant plans to solve mysteries. And Fred too. His leadership skills and his knack for setting up traps can be the focus of some really cool fanfiction stories.
Obviously, Scooby Doo himself is a must - include. Shaggy is also very popular as his sidekick. Fred, with his trap - making skills, is another great character. And Velma, with her brains, always adds depth to the story. Daphne can also be included for her charm and occasional moments of bravery.
One idea could be to create a fanfiction where the gang gets trapped in the Chest of Demons with the 13 ghosts and have to find a new way to escape. Another could be a story about how one of the ghosts was wrongly accused and the gang has to help prove its innocence. Or perhaps a fanfic where the gang discovers a hidden 14th ghost that is the key to controlling all the others.
In my opinion, Mystery Inc. as a whole is the best to focus on. You can write about their teamwork and how they complement each other. For instance, Velma's brains, Fred's leadership, Daphne's courage, and Scooby and Shaggy's comic relief all work together to solve the mysteries. You could also create a story where they face a challenge that tests their friendship and teamwork, like when they are framed for a crime they didn't commit and have to clear their names while still solving the mystery at hand.
I think Pikachu would be really interesting. It's so cute and energetic. In the fanfiction, it could use its electric powers to light up spooky places that Scooby Doo and the gang are exploring. Also, its reactions to all the strange things in Scooby Doo's world would be hilarious.
Naruto and Shaggy could be an interesting pairing. Naruto's high - energy and brave nature could contrast with Shaggy's cowardly but kind - hearted personality. They could learn from each other. Naruto could teach Shaggy to be more courageous, and Shaggy could introduce Naruto to some delicious human world food.
Naruto and Scooby would be a really interesting pairing. Naruto's energy and enthusiasm would contrast with Scooby's cowardice. Naruto could encourage Scooby to be brave and Scooby could teach Naruto about having fun even in scary situations. Also, Naruto's ability to make shadow clones could be used in really creative ways to help solve mysteries, like sending clones to different areas while Scooby and the gang follow the main clue.
The main characters are Scooby - Doo, of course. He's the lovable, cowardly Great Dane. Then there's Shaggy, Scooby's best friend. They are always together, especially when it comes to running away from the spooky things. Fred is the leader of the gang, always coming up with plans to catch the bad guys or solve the mysteries. Daphne is the stylish and brave member, and Velma is the smart one who often figures out the clues.
