Who could be the main character in a 'fallen star fairy tail fanfic'?

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.

A fallen star in this fanfic could be a metaphor for a character's fall from innocence. In Harry Potter, think of how some characters like Draco Malfoy started out with a certain level of innocence but were influenced by their families and the dark side. In Fairy Tail, a character might start as a bright - eyed newbie but then face hardships that cause them to lose that initial spark. The fallen star could then be the focal point of their journey to regain what they've lost or to come to terms with their new self.

It could be Sasuke. Since he has the Sharingan which is related to the Kamui ability in a way. He could be transported to the Fairy Tail world and his brooding and powerful nature would make for an interesting dynamic as he tries to find his way back home while getting involved in Fairy Tail's affairs.

Natsu could be the main character. His impulsive nature might lead him to find the cursed sword first. He would initially think it's just a powerful weapon he can use against his enemies, but then he realizes the sword is slowly corrupting him. This would set him on a journey to get rid of the curse while still trying to protect Fairy Tail.

Erza might be an interesting main character for this fanfic. Given her strong will and combat skills, she could incorporate the guitar into her fighting style. For instance, she could use the guitar as a weapon, slashing enemies with the sharp edges of it while also using its music to disrupt their magic.

One idea could be that the fallen star is actually a powerful wizard from a different dimension who has lost their powers during the fall. They end up in the Fairy Tail world and have to team up with the guild members to regain their powers and find a way back home. Another plot could involve the fallen star being a magical object that holds a great secret, and Fairy Tail members race against an evil guild to discover and protect it.

Gray could be the main character in a harem fanfiction. His cool exterior and his ability to use ice magic in such a unique way make him stand out. He has a bit of a rivalry with Natsu which could add an interesting dynamic to the harem. Characters might be attracted to his brooding nature and his underlying loyalty to his friends and the guild.

It could be a new character, like a street - smart orphan who has learned to steal to survive. This character sees Fairy Tail as a source of wealth at first but then discovers there's more to the guild than just gold and jewels. Another option is an ex - member of a rival guild who turns to thievery after being exiled and decides to target Fairy Tail for revenge. Or it could be a magical creature, like a mischievous imp with the power of invisibility that steals from Fairy Tail just for fun.

Lucy would also be a great main character. Since she has a collection of celestial spirits, adding a genie to her story would be fascinating. She could struggle with whether to use the genie's wishes or rely on her spirits, and the genie might be jealous of her celestial spirits, leading to conflict and character development.

Natsu could be an interesting choice. Imagine if he accidentally caused a great deal of damage during a battle and had to make up for it. He would use his fire - dragon - slayer magic in new ways to help the guild and the people they protect.
