In Fairy Tail fanfic, the 'Eye of the Black Dragon' could be a powerful and mysterious object. It might be related to the power of the black dragon. Maybe it has some special abilities like being able to control dark magic or unlock hidden powers within characters. However, it really depends on how the specific fanfic writer has defined it.
It depends on the fanfic. In some cases, it could be a powerful villain who has the 'Eye of the Black Dragon' and uses it to cause chaos. For example, a dark wizard might have found it and is using its power to take over the world in the story.
The black dragon itself can be a main character. Writers might explore its backstory, its motives, and its personality. It could be a misunderstood creature, or a powerful and menacing force that the Fairy Tail guild has to deal with. In some fanfictions, the black dragon might have a name and a complex history that unfolds as the story progresses.
There could be a fanfiction where a black dragon is actually a reincarnation of an ancient Fairy Tail mage. This dragon has memories of its past life and tries to reunite with its former comrades while dealing with its new dragon form and powers. It would be a story full of mystery and self - discovery.
One common theme is power growth. Writers often explore how the Black Fire Dragon Slayer gets stronger over time. Another theme is friendship, just like in the original Fairy Tail series. The relationships between the slayer and other guild members are often developed further in fanfictions.
Gray Fullbuster can be quite popular in these fanfictions too. His ice - make magic contrasts with the Black Dragon Slayer's power, which can lead to some cool battles and interactions. Erza Scarlet is also a favorite. Her strong and fearless personality makes for great scenes when she teams up with or opposes the Black Dragon Slayer. And sometimes, characters like Gajeel Redfox, another dragon slayer, are popular as they can have a unique dynamic with the Black Dragon Slayer.
One interesting concept could be exploring the Black Dragon Slayer's backstory in more depth. Maybe delving into how they came to be a dragon slayer and the trials they faced during their training. Another concept might be creating unique relationships between the Black Dragon Slayer and other characters in the Fairy Tail guild. For example, a deep friendship or a rivalry that adds more drama to the story.
Natsu could be a great main character. His love for adventure and his already powerful dragon - slayer magic would make him a natural fit to be involved with the mystery of the Eye of the Black Dragon. He could use his fire magic in new and exciting ways while trying to uncover the secrets of the Eye.
One idea could be exploring the origin of the Eye of the Black Dragon. Maybe it was created by an ancient magic long forgotten. Another could be a story where a character has to protect the Eye from dark forces who want to use its power for evil.
