A possible plot is that a DeviantArt fan, let's say a single parent, has a new baby. The parent is part of a DeviantArt community that decides to create a special project for the baby. They make a digital scrapbook on DeviantArt filled with artworks dedicated to the new baby. The baby's presence in the community becomes a source of inspiration, and the 'loud' part could be how the community celebrates the baby's milestones in a very vocal and creative way.
One plot idea could be that there is a young couple who are huge DeviantArt fans. They just had a new baby. They start to decorate the baby's room with prints of their favorite DeviantArt works. As the baby grows, it seems to be especially attracted to the colors and shapes in those artworks. Whenever they are in the room, the baby is calm and happy, which is quite different from being 'loud' in other situations.
Maybe the story is about a group of friends who are all DeviantArt fans. One of them has a new baby. They all try to come up with the most creative and 'loud' (in terms of being attention - grabbing) way to introduce the baby to the world of DeviantArt. They might create a huge mural in their local park inspired by DeviantArt and have a big celebration there with the baby present. This could be the start of the new baby's journey as a DeviantArt fan.
It could be about a new baby in a family who is a big fan of DeviantArt. Maybe the baby is born into a family of artists or art lovers, and they are already planning on introducing the baby to the wonderful world of DeviantArt as it grows up. For example, the parents could be thinking of using DeviantArt as a source of inspiration for the baby's future art education.
A possible plot could be that in the DeviantArt fanfiction world, Stitch and Angel Baby Amber are from different factions. But they fall in love despite the odds. They then have to fight against the rules and prejudices of their respective factions to be together. This would be a story full of drama, action and romance.
Perhaps the fanfiction could revolve around the challenges during the birth. There could be some complications, but through the love and support of the family and the skills of the medical staff, baby Shikadai is born safely. It could also show how the community around them comes together to support the new family during this time.
One idea could be that Santana discovers she has the power to heal. She starts out small, helping injured animals in the park. But then a major disaster strikes the city, like an earthquake, and there are many injured people. Santana has to overcome her shyness and fear of being discovered to use her powers to save as many as she can. She becomes a symbol of hope in the city.
Another plot could involve Lynn Loud Sr trying to teach Luan Loud some old - fashioned values. Luan, being her humorous self, might find unique ways to either embrace or subvert those values. For example, if Lynn Sr tries to teach her about the importance of hard work, Luan could turn it into a comedy skit about different jobs that ends up inspiring the whole family to work together on a project.
One idea could be exploring the backstory of a minor character in the game, like a random caravan trader. You could create a whole story about how they got into the caravan business, their adventures on the roads, and the dangerous encounters they've had. Another plot could revolve around a new faction emerging in the Mojave Wasteland, and how it affects the existing power balance among the NCR, Legion, and Mr. House. Maybe this new faction has a unique ideology or technology that shakes things up.
One idea could be that Lincoln Loud discovers a rare and powerful Pokemon in Royal Woods. He then has to keep it a secret from his sisters while training it. Another could be the Loud sisters each getting a Pokemon that reflects their personalities. For example, Lola might get a Jigglypuff because it's cute and girly.
A cool plot for 'the loud house crossover fanfiction' might involve a crossover with 'My Little Pony'. The ponies could come to Royal Woods, and the Loud sisters could be fascinated by their magic and cuteness. Lincoln might have to figure out how to get the ponies back to Equestria while also dealing with his sisters' excitement. Or perhaps the Loud family travels to Equestria and has to adapt to a world ruled by ponies.
One idea could be that Naruto somehow ends up in the Loud House world. Maybe he's on a mission and a strange jutsu goes wrong, transporting him there. He could use his ninja skills to help the Loud siblings out with their daily problems, like getting rid of a bully at school using his shadow clone jutsu.
One idea could be that the Loud family members gain superpowers similar to the Avengers and have to team up to save Royal Woods from an alien invasion. For example, Lincoln could be like Captain America, leading the group with his strategic mind.
