Well, aside from Simon, Alvin is bound to be a central figure. He'd probably come up with all sorts of crazy plans to get Simon well again. Theodore too, as he's always been close to Simon. He might be the one to notice the small changes in Simon's condition first. And of course, Dave could also be an important character. He's like their guardian, so he'd be involved in taking care of Simon, getting him to the vet if needed, and making sure the other chipmunks don't get into too much trouble while trying to help.
Definitely Alvin and Theodore. Alvin would use his quick thinking and boldness to try and find a solution for Simon's illness. He might be the one to search for a special medicine or a magical cure. Theodore, on the other hand, would be the gentle presence by Simon's side. He'd keep Simon company, tell him stories, and make sure he's comfortable. There could also be other minor characters from their world, like the neighbor's cat that might seem like a threat at first but could end up being an unexpected helper in some way.
In this fanfic, Simon could get sick from an encounter with a new, unknown substance in their environment. This makes him act in very un - Simon - like ways. Alvin and Theodore are initially confused but then realize they need to find a cure. They might go on an adventure to seek help from other animal friends or even humans who are kind to them. Along the way, they face various challenges and obstacles that test their determination to save Simon. This fanfic could also explore the emotional side of the chipmunks as they worry about losing Simon.
In Alvin x Simon fanfiction, they might go on an adventure together. For example, they could get lost in the forest while trying to find a special type of nut for a recipe. During their time lost, they rely on each other's skills. Alvin uses his quick thinking and physical abilities to get them out of some tricky situations, like crossing a small stream. Simon, on the other hand, uses his knowledge of the forest's flora and fauna to find food and shelter. Through this adventure, their bond grows stronger.
One possible fanfic could be about how Simon's glasses are not just a simple accessory but a symbol of his intelligence. Maybe in the fanfic, the glasses get lost and the other chipmunks go on a wild adventure to find them, realizing how important they are to Simon.
They could compete in a school - like setting. Imagine they are in a chipmunk academy and there's a big academic competition. Alvin is more street - smart and Simon is book - smart. They initially see each other as rivals in this competition. But as the story progresses, they realize that by combining their different types of intelligence, they can outperform all the other chipmunks.
Simon's calmness is also a good trait. In a fanfic, when Alvin and Theodore are panicking, Simon can stay calm and come up with a plan. Like if they're lost in the woods, Simon can analyze the situation, look at the stars or the plants around them to find their way home. He is also very observant, which means he can notice small details that others miss. This can lead to interesting plot twists, such as when he notices a strange mark on a tree that leads them to a hidden treasure.
One idea could be Simon getting lost in a magical library and having to use his intelligence to find his way out while also uncovering secrets about the Chipmunks' past. Another could be Simon falling in love with a new character who challenges his intellectual side and makes him see things in a different way. Or perhaps Simon having to save the day when Alvin and Theodore get into a really big mess by using his scientific knowledge.
Love and friendship are common themes. Since Simon and Jeanette have a special relationship, fanfics often explore how they care for each other, support one another in different situations. Another theme could be adventure. They might go on exciting adventures together, like exploring a mysterious forest or an old attic full of secrets.
Perhaps in the fanfic, Simon's glasses are enchanted. One day, they start to glow and lead the chipmunks to a hidden library in the forest. Inside the library are ancient texts that only Simon can read with his glasses. The chipmunks then have to protect the library from a group of raccoons who want to destroy it.
One popular 'alvin and the chipmunks simon and jeanette fanfic' might be those that focus on their adventures in the human world. For example, a story could be about Simon and Jeanette going on a scientific exploration together while dealing with the chaos that Alvin often causes. Another could be a sweet, romantic story of how Simon and Jeanette first fell in love, perhaps with some cute moments of them sharing their love for knowledge.
The main characters would be Alvin, Simon, and Theodore. Alvin would be leading the way in most of their high school escapades. Simon would be there to keep Alvin in check with his logical thinking. Theodore would be the heart of the group, always bringing a sense of warmth. Additionally, there might be a popular student in high school who becomes their rival at first but later becomes a friend. There could also be a school principal who has to deal with all the chaos that the chipmunks sometimes create.
