Gray is another character that features prominently. His cool - headedness (well, most of the time) and ice - make magic can provide an interesting contrast to Daphne's actions. In fanfictions, he could be the one who figures out the weaknesses in Daphne's plans through his logical thinking.
One interesting fanfiction could be one that focuses on Daphne's backstory before the arc. It might explore her motives and how she came to be the character she is in the arc.
Lucy is another popular choice. In the Edolas arc, her intelligence and determination can shine through. Maybe she's the one who figures out how to navigate the strange new world and its magic, and her relationships with the Edolas versions of the characters can be explored in interesting ways.
Natsu is often very popular. His fiery personality and powerful dragon - slayer magic make him a natural protagonist in many fanfictions. Writers like to explore his backstory further, especially his connection to Igneel. They also put him in various new adventures, like teaming up with unlikely allies against new and more powerful enemies.
Gray is another one. His cool - headedness and ice - making magic can be a great contrast to the more stealthy and fast - paced ninja elements. Fanfictions might explore how he could use his ice powers in a ninja - like combat scenario, like creating ice clones or using ice as a means of stealth.
Mard Geer is a very interesting character to focus on. His complex relationship with Zeref and his extreme loyalty to Tartaros provide a lot of material for exploration. You could also write about Gray Fullbuster. His struggle with his dark side and his connection to the demons of Tartaros make him a great focal point. Another option is Erza Scarlet. Her strength and determination in the face of the Tartaros threat can lead to some exciting storylines.
Well, Naruto is a staple in these fanfictions. His ability to make friends and his growth as a character are always interesting to explore. From Fairy Tail, Erza is quite popular. Her strong - willed personality and her wide array of armors and combat skills can make for some great crossovers. She could potentially teach Naruto some combat strategies, or vice versa, as they face off against common enemies in the fanfiction world.
Lucy Heartfilia could be popular too. Her celestial spirit magic and her kind - hearted nature can add a different dynamic to the stories. In a fanfiction, she might befriend Naruto Dragneel and help him understand the Fairy Tail world better, or perhaps they go on an adventure together to find a rare celestial spirit that has some connection to Naruto's world.
Mirajane is a popular choice too. She has a mysterious side to her, and in the fanfictions, she could use her unique abilities to help Natsu or be involved in the events that the Fairy Tail members are watching. Also, Laxus might be included. His powerful magic and complex character can add depth to the fanfiction stories, especially when his relationship with Natsu and the rest of the guild is explored.
Naruto is definitely one of the most interesting. His unique abilities from the Naruto series, like his ability to use different types of chakra and his signature jutsus, make him stand out in the Fairy Tail world. He often brings a new perspective and a different set of skills to the table.
Natsu is often a very popular character in Fairy Tail Empire fanfiction. His powerful fire magic and his brash but endearing personality make him a great protagonist in many stories.
