In this fanfiction, Harry's main opponents could include some powerful dark wizards from the game's lore. These wizards might have been created specifically for the game and have unique and dangerous magic. Also, there could be a group of rival wizards from a different magical guild in the game. They see Harry as a threat to their dominance in the game and constantly try to outwit and out - magic him. And don't forget about some of the more challenging in - game bosses that are designed to test the skills of the best players, like a giant magical beast that guards a valuable in - game item.
Voldemort could be one of his main opponents, even in the game world. Voldemort might try to use dark magic within the game to defeat Harry. Another could be Draco Malfoy. Draco would be jealous of Harry's success in the game and try to undermine him at every turn, using his family's influence within the game's magical society.
It could be some Death Eaters who are causing chaos at the World Cup. They might be trying to disrupt the event and target Harry.
Maybe Harry would use magic spells in the game world to defeat virtual monsters. For example, he could use 'Expelliarmus' to disarm a powerful in - game boss. He might also team up with Ron and Hermione in the game, with Hermione using her vast knowledge of spells and potions to strategize and Ron providing his usual loyal and sometimes comical support.
Hermione and Ron would surely be his top allies. Hermione with her vast knowledge of magic and Ron with his loyalty and combat skills. They've been with Harry through thick and thin. Also, the members of the Order of the Phoenix like Sirius Black (if he's still alive in the fanfiction), Lupin, and Moody could be great allies. They have experience and are very powerful wizards.
Hermione would definitely be one of his top allies. Her intelligence and knowledge of magic and history would be invaluable in helping Harry rule. She could advise him on laws and policies, especially those related to education and the treatment of non - human magical beings. Ron would also be an ally. His loyalty and his understanding of the wizarding world's less - sophisticated side could help Harry connect with the common wizards.
Hermione would be a likely colleague. She's highly intelligent and could be teaching a subject like Ancient Runes or Arithmancy. Ron could also be there, perhaps as a flying instructor or teaching something related to magical creatures. Neville might be a Herbology professor, given his love and talent for that subject. Luna could be teaching something really unique, like the study of magical creatures that are often overlooked or misunderstood.
Hermione would definitely be one of his allies. She is smart and resourceful and would be able to help Harry navigate the new political and magical situations he faces as a prince. For example, she could research ancient laws and prophecies related to his new status.
Voldemort and his Death Eaters would still be the main enemies. But now, Harry's guns would pose a new threat to them. They might not be used to dealing with such Muggle - like weapons, even if they are magically enhanced.
In some fanfictions, it could be an original character created by the author. Maybe a witch who was the result of an affair that his father had before he married his mother. However, this is completely against the canon of the original books, but in the world of fanfiction, anything is possible.
In some fanfictions, it could be Sirius Black. Some fans like to imagine that Sirius had a deeper connection to James Potter's family than just being best friends. They might create a scenario where there was some sort of magic or prophecy involved that made Sirius more than just Harry's godfather, but his actual father in this alternate story line.
Perhaps Hagrid could be his mentor. Hagrid has a lot of knowledge about magical creatures and their parts, which could be useful for Harry in his blacksmithing. He could show Harry how to use things like dragon scales or unicorn hairs in his creations.
