They could be catalysts for change. Harry Potter's family's arrival in the Fairy Tail world could shake up the existing power dynamics. They might introduce new ideas about magic and how it should be used. For example, they could advocate for more inclusive magic, which might change the way the Fairy Tail guild operates. Their presence could also lead to new alliances being formed, as other guilds might be interested in the unique magic that Harry's family brings.
In a Fairy Tail fanfiction, Harry Potter's family could play the role of magic mentors. They could teach the Fairy Tail wizards some of the unique spells and magical techniques from the Harry Potter world. For example, they could introduce the concept of Patronuses to help the Fairy Tail wizards fight against dementor - like creatures in their world. Also, Harry's family could bring in their knowledge of magical creatures from their world, which could be useful in Fairy Tail's quests.
Harry's family could be powerful allies. His father, for instance, might be a skilled fighter and could join in battles against the dark guilds in Fairy Tail. His mother could use her magic to heal the wounded wizards in the guild. And Harry himself could be a source of inspiration for the Fairy Tail members with his experiences of facing great evil.
Harry's father could be a strong and fearless mage in Fairy Tail, leading quests and battles. His mother might be a healer, using her magic to help the injured in the guild. And Harry could be a young mage with a lot of potential, similar to how he was in the Harry Potter series. He could be the one to discover new magic in the Fairy Tail world.
They could be antagonists. Maybe they are a family of dark wizards who oppose Harry and his friends. They could try to steal the Philosopher's Stone or disrupt the Triwizard Tournament.
One way could be through a magical portal. Maybe a spell gone wrong in the Harry Potter world creates a portal that leads to the Fairy Tail universe. Harry's family could then be part of the adventure there, with his parents' magical skills being useful in the Fairy Tail guild. For example, his father James could use his Animagus ability to help in a mission where stealth is required.
One possible plot could be that a character from Fairy Tail gets accidentally transported to the Harry Potter universe but is neglected by the magical community there. They then have to find their own way to get back while also discovering new magical abilities and making unexpected friends.
In a fanfiction, Harry Potter's family could be integrated into the Fairy Tail universe in various ways. For example, they could be mages with unique magic abilities similar to those in Fairy Tail. Maybe Harry's parents could be part of a powerful guild, and Harry himself could grow up learning both the magic of his original world and the magic of Fairy Tail. Their presence might also change some of the key events in the Fairy Tail story line, bringing in new perspectives and plot twists.
Dwarfs can play the role of guardians. They could be protecting ancient magical artifacts or places of great power. For instance, a dwarf might be the sole protector of a hidden chamber in Hogwarts that contains a powerful spellbook.
One common role is being a powerful ally. His Saiyan strength helps the Fairy Tail guild in battles against tough foes.
Gogeta could play the role of a powerful ally. He could use his strength to protect the Fairy Tail guild from powerful enemies. For example, when the guild is under attack by a dark guild, Gogeta could easily defeat the attackers with his superhuman abilities.
Often, INTPS in Harry Potter fanfiction are the ones who have a deep understanding of the magical theory. They are not as interested in the glory or the social aspects of the wizarding world. Instead, they are focused on understanding how magic really works. They might be found in the library, poring over ancient tomes, trying to unlock the secrets of magic that have been lost over time. They could be the ones who end up making important discoveries about magic that even the professors at Hogwarts are unaware of, like a new way to perform transfiguration or a previously unknown property of a magical creature.
Well, in such a fanfiction, there could be some really emotional moments. The family members who were separated for a long time might have tearful reunions. There could be new character developments too. For instance, if Gray meets his family again, he might get some new magic abilities passed down from his ancestors. Also, the family reunion could be a chance to resolve old feuds among different families within the Fairy Tail world.
