It would be amazing. With a system, you could gain unique powers and abilities that are not available in the normal Fairy Tail world. For example, you might be able to level up your magic faster or have special skills like instant teleportation within the guild. You could also use the system to analyze your opponents' weaknesses, making you a formidable mage in battles.
One advantage is the power boost. The system can help you quickly become a strong mage. For instance, it might offer training programs that are more effective than the regular ones in Fairy Tail. Another advantage is the knowledge. You could get information about the world and its secrets through the system that others don't have.
Well, it would be an interesting concept. Lucy is a very popular character in Fairy Tail. If someone was reborn as her in a fanfiction, they might have to deal with her magic, her relationships with the other guild members like Natsu and Erza. They could potentially change the course of the story, for example, by using modern knowledge to solve problems in the Fairy Tail world more efficiently.
One possibility could be that a main character, perhaps Natsu, is somehow reborn without emotions. He would then go through the world of Fairy Tail in a very different way. For example, he might not be as eager to fight for his friends because he doesn't feel the passion or loyalty he once did. This could lead to a lot of conflict within the guild as they try to figure out how to bring back the old Natsu.
You can start by equating certain types of Fairy Tail magic with the existing magic in Skyrim. For example, fire magic from Fairy Tail could be similar to the destruction spells in Skyrim. The Fairy Tail mages could also teach the locals in Skyrim new ways to use magic, like how to combine different elements to create more powerful spells.
The magic in Fairy Tail could be combined with Pokemon elements by having spells that are related to Pokemon types. For instance, a water - mage could use a spell to create a Pokemon - like water creature. Or a lightning - mage could summon an electric - type Pokemon - inspired bolt of energy.
The system - if it has a leveling - up feature - could make the character progress at a different rate compared to others. This might create a bit of a gap in the beginning. But as the character shares their experiences and knowledge gained from the system, it can bring the guild closer together. For example, if the system unlocks new training methods, the character can introduce them to the guild, improving everyone's abilities and creating a more positive and collaborative atmosphere within the guild.
The system could bestow powers related to physical enhancements. Maybe it gives superhuman strength, allowing the character to lift extremely heavy objects or deliver powerful punches. There could also be the power of rapid regeneration, so that any wounds received in battles heal almost instantly. In addition, the system might provide the ability to teleport short distances, which is very useful for dodging attacks and getting to strategic positions quickly.
On the other hand, there's a possibility of them having a change of heart. The positive and friendly environment of Fairy Tail could gradually influence them. They might start to form real bonds with the characters and slowly let go of their psychopathic tendencies. The Fairy Tail members' acceptance and kindness could be the key to their redemption.
It could be an ancient evil entity that has been sealed away for centuries. The OC's rebirth somehow disturbs the seal, and this entity awakens. It views the Fairy Tail guild as a threat because of their positive influence in the world. So, it starts to target the guild, and especially the OC, as they are a new and unknown factor in the fight against it.
