One common theme could be self - discovery. Harry might be on a journey where he learns more about himself as he walks through different situations or worlds. Another theme could be adventure. Since he's 'the Walker', there may be a lot of traveling and exploration involved, encountering new people and places along the way.
I'm not sure specifically as it depends on how the fanfiction is written. But surely Harry Potter would be one of the main characters. There might also be a character related to the 'walker' concept who could be a central figure, perhaps someone who has a special connection to this 'walker' identity and interacts closely with Harry and his friends.
The plot could involve Harry Potter being sent on a mission like Allen Walker. He might have to travel to different dimensions, using his magic skills along with Allen Walker - like abilities. For instance, he could use his Patronus to combat the dark forces that are similar to the Noah family in D.Gray - man. It would be a blend of the magical world of Harry Potter and the dark - fantasy world of D.Gray - man.
The 'harry potter the walker fanfiction' could be interesting due to its potential for exploring uncharted territories in the Harry Potter world. It might delve into the backstories of minor characters in relation to this 'walker' concept. The fanfiction could also offer a fresh view on the Hogwarts curriculum or the way magic is taught, influenced by the presence of the 'walker'. Additionally, it could introduce new magical creatures or reinterpret existing ones in a way that is tied to the 'walker' idea, making the whole magical world seem even more vast and full of possibilities.
It could be really strange. Maybe Harry Potter, instead of being a wizard, is a White Walker. He might have the ability to raise the dead in the wizarding world, which would cause chaos. His friends would be horrified and they would have to find a way to stop him or bring him back to his normal self.
Jack Walker in this fanfiction is likely the main character. He's someone who has his own story within the Pokemon - themed world. Maybe he's a unique trainer with special abilities or a backstory that sets him apart from other trainers in the fan - made story.
I'm not sure if it's a very popular concept. Harry Potter and Allen Walker are from two very different universes. Harry Potter has its own vast and rich lore within the wizarding world, and Allen Walker is from D.Gray - man. While in the world of fanfiction anything can be created, it might be a rather niche idea.
Yes, in some fanfiction circles, Harry the Walker can be quite well - known. What makes it special often depends on the unique plotlines and character developments within those specific fanfictions. For example, the author might give Harry the Walker extraordinary abilities or put him in very unusual situations that deviate from the norm of the original source material (if there is one), which makes the character stand out and attracts readers who are looking for something different from the typical stories.
A 'Harry Potter Marries Sarah Walker' fanfiction would likely involve a lot of character development. Harry, having grown up in the wizarding world, has a certain set of values and experiences. Sarah Walker, on the other hand, has her own story. When they come together, they would have to learn about each other's worlds. For example, Harry would have to explain things like the Ministry of Magic, Hogwarts, and the concept of magic itself to Sarah. Sarah might introduce Harry to her friends or family (if applicable in her story) and show him a different side of life. Their marriage could be a symbol of the coming together of two different fictional universes, leading to new adventures and challenges.
One possible plot could be that Sarah Walker has some special ability that is needed in the wizarding world. Harry meets her, they fall in love, and then they have to deal with the challenges of combining their two very different worlds. Maybe there are dark wizards who are interested in Sarah's ability and they try to capture her.
