Well, if Harry Potter learned Fairy Tail magic, he'd probably become even more powerful. He could combine spells like Expelliarmus with Fairy Tail's powerful attack magic. His adventures would take a whole new turn as he'd have different ways to fight the dark forces.
Well, it could be really exciting. Harry's magic from the wizarding world of Hogwarts would mix with the magic in Fairy Tail. Maybe he'd learn new types of magic, like Fairy Tail's unique elemental magic. And he could team up with Natsu and the others to take on powerful enemies. His knowledge of potions and spells might also come in handy during their adventures.
In such a fanfiction, Harry might discover ancient spells that give him an edge in battles. For example, he could learn old defensive magic that can protect Hogwarts in a more powerful way than the existing spells. He might also use old magic to communicate with long - lost magical creatures that hold secrets of the wizarding world.
To adapt to Fairy Tail magic in a fanfic, Harry Potter would face quite a challenge. First of all, he has to get used to the more flamboyant and often physically - manifested forms of magic in Fairy Tail. In Hogwarts, magic is more about incantations and wand movements. But in Fairy Tail, there are all kinds of magic that are expressed in more dramatic ways. He would need to make friends within the Fairy Tail world quickly, because friendship is a key element in using their magic effectively. He could start by learning simple spells or magic types, like the basic elemental magics. And he'd have to learn how to work in a team, which is something that Hogwarts doesn't always emphasize as much as Fairy Tail.
Well, it depends on how the author writes it. Maybe Voldemort would initially be in disbelief. But once he accepts it, he could start to manipulate Harry in different ways. He might think that by controlling Harry, he can control the Horcrux within him. This could create some really interesting plot twists where Harry has to resist Voldemort's attempts at a much deeper level than just physical attacks.
Well, he might discover a long - lost spell. Maybe it's a spell that can make inanimate objects come to life and help him in his daily tasks at Hogwarts.
If Naruto and Sasuke were in Fairy Tail, it would be quite the mix - up. Naruto's positive and determined attitude would likely inspire many of the Fairy Tail members. His ability to make friends easily could change the dynamics within the guild. Sasuke, on the other hand, would probably be more of an enigma. His dark past and brooding nature might make some members cautious, but his strength would also earn respect. He could learn some new magic skills in the Fairy Tail world while also teaching his ninja techniques to interested parties.
A 'Fallen Star' in a Harry Potter and Fairy Tail fanfic could be a very interesting concept. It might refer to a character who was once highly regarded but has fallen from grace. In the context of Harry Potter, it could be a wizard who has turned to the dark side, perhaps influenced by the Death Eaters' ideology. In Fairy Tail, it could be a mage who has lost their power or been exiled from the guild. The fanfic could explore their journey to redemption or further descent into darkness.
He might be quite amused. Fanfics often contain different interpretations of the characters and the wizarding world. He could find some creative ideas in them that he never thought of before, like unique magical spells or new backstories for his friends.
He'd fit in by sharing his magic skills. His ability to perform spells without using hand gestures (unlike most Fairy Tail mages) would be a novelty. He could also bond with the other members over their love for magic.
It might be a story where Harry delves into the family magic in order to solve some sort of mystery. For example, he could be looking for a way to defeat a new dark force and realizes that the family magic holds the key. He could learn new forms of magic related to protection or divination that are unique to his family.
