I'm not sure of specific 'This Means War' FDR and Lauren fanfiction off the top of my head. But you could try searching on fanfiction websites like Archive of Our Own. They usually have a wide range of fanfictions for different movies and characters.
One plot idea could be FDR and Lauren going on a secret mission together that is related to the spy world of the movie but in a more personal way. Maybe they have to infiltrate a high - society event to stop a new threat.
One common theme is friendship. Tuck often forms new friendships or strengthens existing ones in these fanfictions. Another theme is adventure, as Tuck is usually involved in some sort of exciting journey.
Well, one interesting aspect could be the unique character interactions. In a 'This means war' type of scenario within the Harry Potter universe, we might see characters who are usually allies having to compete or oppose each other in new ways. For example, Gryffindors and Hufflepuffs could be on opposing sides for some reason, leading to interesting dynamics between friends from different houses. Another aspect could be the creative use of magic. The author might come up with new spells or ways of using magic in the context of this 'war' situation, which adds a fresh perspective to the already rich magical world of Harry Potter.
Another good one is 'Tuck and the Lost Treasure'. It's a story where Tuck goes on a quest to find a long - lost treasure. Along the way, he meets new characters and has to overcome various obstacles. The description of the settings in this fanfiction is really vivid, making it a great read for any 'This Means War' fan.
The Return of the God of War was a term commonly used in novels to describe a hero or God of War who returned to his hometown or battlefield to start a fierce battle again after experiencing a series of battles and adventures. This phrase was often used to describe a character who had become stronger and more determined after a long period of departure and return.
Franklin Delano Roosevelt's life was filled with great challenges and achievements. He was elected president during a time of crisis, the Great Depression. He introduced reforms that changed the role of the federal government in the economy. For example, Social Security was one of his initiatives that still has a huge impact today. In the context of WWII, he showed strong leadership, from mobilizing the military to making diplomatic efforts. His leadership style and policies not only shaped the US during his tenure but also had a long - lasting influence on the nation's development.
It could be that Bella has a love interest that Lauren also fancies. In fanfiction, love triangles are common. If the object of affection shows more interest in Bella, it would make Lauren jealous. For example, if there's a guy both of them like, and he always chooses Bella over Lauren.
Definitely the two male leads. Their competitive and comical relationship is the heart of the movie and can be explored further in fanfic. You can show more of their backstory and how they became such rivals.
