What are some interesting plot developments in 'fairy tail natsu is a girl fanfiction'?

One possible plot development is that Natsu, as END, could be hunted by various magical organizations who see him as a threat. This would put him on the run and force his Fairy Tail friends to either protect him or try to stop him if they believe he's too dangerous. Another development could be that Natsu discovers new abilities related to END that give him an edge in battles but also come with a cost, like draining his life force or affecting his mental state.

One possible plot development could be that Natsu discovers a new and powerful magic during his return that gives him an edge in saving Fairy Tail. Maybe he finds a way to combine his Fire Dragon Slayer magic with some ancient magic he stumbles upon on his journey back.

In some fanfictions, when Natsu turns into END, there's often a huge power boost. This can lead to him facing off against stronger enemies that he couldn't before. For example, he might take on the most powerful dark mages single - handedly. His appearance also changes, usually becoming more menacing with features associated with END. This transformation can also cause some internal conflict within the Fairy Tail guild, as some members may be afraid of his new form.

One idea could be a mission where Natsu and Laki are paired up by accident. Laki, being more of a support - type mage with her wood - based magic, could initially be intimidated by Natsu's brash and powerful fire magic. But as they face challenges together, she learns to stand up to him and they develop a mutual respect. For example, they might encounter a powerful earth - based monster that is immune to Natsu's fire. Laki's ability to manipulate the surrounding trees to entangle the monster gives Natsu the chance to figure out a new strategy to defeat it.

One idea could be that Natsu is exiled due to a false accusation of using dark magic. He then has to journey alone to prove his innocence, encountering new friends and foes along the way. Maybe he discovers a new form of magic during his exile.

One idea could be Natsu going on a solo mission to a far - off land that has a different type of magic entirely. He has to learn to adapt and control this new magic to complete his task. Another could be Natsu training a new generation of Fairy Tail wizards, passing on his unique brand of magic and combat skills.

One idea could be that Mystogan and Natsu have to team up to face a powerful dark wizard. Since Mystogan is usually more reserved and Natsu is hot - headed, their clashing personalities could lead to some humorous and intense moments during the fight.

One interesting plot idea could be Natsu going on a special quest with each member of his harem separately. This would allow for character development of both Natsu and the individual harem members. For example, when he's with Lucy, they could discover a new type of celestial spirit magic that only works in a specific, long - lost realm. Another idea is that an enemy targets Natsu's harem to get to him, so he has to protect them all while also dealing with his growing feelings for each of them.

In this fanfiction, Natsu could discover that his abandonment was part of a bigger plan within Fairy Tail to protect him from a greater threat. He might initially be angry and resentful, but as he uncovers the truth, he has to decide whether to forgive his old guild or not. He could also meet other characters who were also once abandoned and form a bond with them to face the challenges together.

One plot idea could be that Zeref discovers a way to reverse his curse through Natsu. Since Natsu is his creation, there might be some hidden connection that could be explored. Maybe Zeref tries to use Natsu's unique dragon - slayer magic to break the chains of his dark magic.
