In such a fanfic, Harry might accidentally break a lot of magical laws. For example, he could perform spells in the wrong way, leading to unexpected and chaotic results. Maybe he'd use a powerful spell without understanding the proper incantation or wand movement, causing magical backlash.
Maybe he discovers a new form of magic while breaking the rules. It could be something that was forgotten or forbidden. He might then have to decide whether to keep it a secret or share it with his friends and professors. This could lead to a whole new adventure as he tries to understand and control this new magic, all while avoiding getting caught by the authorities.
By creating humorous situations. For example, Harry could try to use a simple spell like Lumos but end up making the whole room explode with light. This kind of comical mishap can draw readers in.
In the fanfic, it might be that the people around Harry treat him as an ordinary person most of the time. So, he doesn't get the sense that he is a hero. For example, his friends might joke around with him and not give him the 'hero - treatment', which makes him oblivious to his heroic status.
Perhaps Aramis is a character in a story or a group of friends where this trait of not being into fanfic has been defined. Maybe in a community of book lovers or media enthusiasts, Aramis stands out as the one who refuses to engage with fan - created content. It could be that Aramis has a very academic or traditional view of literature and media, and fanfic doesn't fit into that view. So, they are known for 'not eating' fanfic.
It could be about a fictional scenario where Harry, perhaps a character named Harry, has the power to rule the world. It might involve him using magic or some extraordinary abilities to take over and manage the entire world, with all the challenges and changes that would bring.
One interesting rule in Harry Potter fanfic could be about the use of magic outside of Hogwarts. In some fanfics, there are strict rules governing this, like having to register with the Ministry first. It adds an extra layer of realism and danger to the story.
Most likely, the main character is Harry. Since it's called 'harry rules the world fanfic', it's a strong indication that Harry is the central figure who is going to be involved in the action of ruling the world.
It could be that he is constantly compared to other more 'flashy' characters in the fanfic world. Those characters might have more obvious powers or more dramatic backstories. So, Harry, with his more understated heroism, doesn't think he measures up and doesn't realise he is a hero too. He feels like he's just an ordinary person in the midst of these seemingly more extraordinary individuals.
