Well, Harry Potter is most likely still one of the main characters. He would be the protagonist adapting to the new gaming - like situations in the fanfic.
One idea could be that in the 'Harry Potter' world, a new magical game is introduced which is similar to 'Monster Gamer'. The characters from 'Harry Potter' start playing it and discover that it has some real - world magical implications. For example, the monsters in the game might start appearing in Hogwarts and the students have to use their magical skills to defeat them, just like in the game.
I really like 'Harry Potter: The Gamer's Ascension'. In this fanfic, Harry discovers he has a gamer system which changes his perspective on magic. It's full of exciting battles where he strategizes like a gamer would. The story also does a good job of incorporating the original Harry Potter elements with the new gamer concept.
One interesting Harry Potter gamer fanfic could be one where the characters are in a virtual reality game within the wizarding world. They have to complete quests using their magical skills in a new, gamified environment. For example, Harry might have to defeat a series of dark wizards in a dungeon - like level that's full of magical traps.
The world - building in this fanfic is often fascinating. It might incorporate different gaming levels or zones within the wizarding world. There could be a 'dungeon' in Hogwarts where students have to face magical creatures and solve puzzles to progress. This adds a whole new layer of adventure and exploration to the familiar Harry Potter universe.
The combination of the familiar Harry Potter world with the concept of gaming. It's like seeing the magical world through a new lens. Harry can now 'level up' his magic skills, which is a cool twist on the traditional magic learning in the original books.
The gamer character themselves is usually quite memorable. They bring a different perspective to the wizarding world, often being more strategic due to their gaming experience.
Character development is key. If you're bringing in characters from both universes, show how they interact and change. For example, if a 'Monster Gamer' character is introduced to the 'Harry Potter' world, they might be amazed by the magic but also teach the Hogwarts students some of their own skills from their game world. Also, make sure to use vivid descriptions. When describing the 'Monster Gamer' monsters in the 'Harry Potter' setting, make it so the readers can really picture them in that magical world.
Well, perhaps the gamer is transported into the Harry Potter world at a crucial moment, like during the Battle of Hogwarts. But instead of just joining the fight as expected, they discover a hidden passage in the castle that leads to a powerful magical artifact that can turn the tide of the battle in a very unexpected way.
I'm not entirely sure as the statement is rather unclear. It could potentially be a fanfiction where Harry Potter is depicted as a gamer within the magical world. Maybe he uses magic in ways similar to how a gamer uses skills in a game.
