The main characters could include some of the new generation as well. For example, Albus Potter or Scorpius Malfoy. They could be at the center of this 'war' in the fanfic, perhaps dealing with the consequences of their parents' actions. Ginny Weasley could also be a main character, as she's a strong witch in her own right. And then there are the Hogwarts professors. Professor McGonagall could be leading the defense of Hogwarts in this war - like situation, and Professor Flitwick could be using his magical expertise to help the side he's on.
Well, a typical plot element might be the discovery of a new, powerful magic item or spell. In this 'This Means War' fanfic, different characters or groups could be fighting over it. It could be that the item has the potential to change the balance of power in the wizarding world. Additionally, betrayal is often a great plot element. A character who was thought to be on one side might switch, creating chaos and fueling the 'war'. And of course, love interests can also play a role. Two characters from opposing sides might fall in love, adding an extra layer of complexity to the conflict.
I'm not sure specifically as there could be many different interpretations. It might be a fanfic that focuses on characters in Harry Potter using certain means to achieve their ends, like a character using magic in an unexpected way to reach a goal.
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.
The original series mainly focuses on Harry's fight against Voldemort and the overarching battle between good and evil. In 'This means war' fanfiction, the conflict could be more complex and not so clearly defined. It might not be just about a single villain but rather multiple factions vying for power. For example, there could be a power struggle between different wizarding schools or groups within Hogwarts itself.
There's no way to tell without reading the fanfic. However, it might feature some of the more popular secondary characters from the Harry Potter books like Luna Lovegood or Draco Malfoy. They could be given a more central role in this fanfic, with the story revolving around their own means and ends.
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.
One great post - war Harry Potter fanfic is 'The Life and Times of Harry Potter'. It delves into how Harry and his friends are rebuilding the wizarding world. It shows their struggles in dealing with the aftermath of the war, like healing the psychological traumas and restoring Hogwarts. Another interesting one is 'After the Battle'.

In this type of fanfic, the Infinity Stones could have a very different effect in the Harry Potter universe. For example, the Time Stone could be used to reverse dark spells or resurrect fallen wizards. However, the Stones' power might also be limited by the magic rules of the wizarding world. The fanfic could delve into how the characters from both universes adapt to the presence of the Stones and how they use or misuse their power.
