Natsu could be a great ally. Since he is also a dragon slayer, he could offer advice and support to Lucy in her elemental dragon - slaying journey. Happy, Natsu's flying cat companion, could also be helpful in terms of providing transportation and some comic relief. Erza is another potential ally. Her strong combat skills and leadership could be valuable when Lucy faces tough dragon - slaying challenges.
One common theme could be self - discovery. Lucy might discover new powers within herself as an Elemental Dragon Slayer, leading to a journey of understanding her true potential. Another theme could be friendship. She may form strong bonds with other characters while on her dragon - slaying adventures. Also, the theme of facing one's fears is likely. Confronting powerful dragons would surely test her courage and force her to overcome her fears.
One interesting aspect could be how she trains to become a Celestial Dragon Slayer. Maybe she discovers an ancient magic that combines the two, and she has to learn to control the newfound power. This could lead to some great character development as she struggles with the increased power and the responsibility that comes with it.
Well, if we consider Lucy as a Dragon Slayer in fanfiction, her magic could be really different from the traditional ones. Maybe she'd have a connection to a celestial dragon, which would be so cool. It would combine her existing celestial spirit magic with the new dragon slayer powers. She could use the stars as a source of power, similar to how other dragon slayers use elements, and it would be a fresh take on her character.
Other dragon slayers could be her potential allies. They might recognize her skills despite her being a princess. Also, magical creatures who are enemies of the dragons, like phoenixes or griffins, could side with her. And some wise old wizards or witches who see her potential might offer their help.
Well, Naruto is likely to be one of the main characters. Since it's a Naruto - related fanfiction, he'll probably be at the center of the story. There might also be characters from the dragon slayer world that are important, like the typical dragon slayer mages. But without reading it specifically, it's hard to say exactly who all the main characters are.
In some fanfictions, Happy, the flying cat, could also be an important character. He could provide comic relief and also be involved in some of Lucy's adventures as a dragon slayer. For example, he might help her find clues or get out of difficult situations. And then there could be original characters created specifically for the fanfiction. These characters could be other dragon slayers or powerful mages that interact with Lucy in different ways.
Another theme could be friendship. In the context of being a dragon slayer, Lucy's relationships with her friends, whether they are also slayers or just her regular comrades, are likely to be explored. Her friends might support her in her new role, or there could be some conflicts related to her new power. Usually, how these relationships evolve is an important part of the fanfiction.
One interesting concept could be the combination of Naruto's ninja abilities with the dragon slayer magic. For example, Naruto might use his shadow clones in a new way while also wielding dragon slayer powers like breathing fire or ice. Another concept could be the interaction between Naruto and the dragon slayer characters from the fanfiction world. Maybe they form teams or compete against each other in unique battles.
There could be a 'Dragon Slayer Lucy' fanfiction where she embarks on a quest to find a missing dragon slayer. Along the way, she uncovers secrets about the origin of dragon slayers. She might also develop a romantic relationship with another character in the story, perhaps a fellow mage who helps her on her journey. This relationship could add an interesting layer to the story as they face various obstacles together.
