Another character who could run a burger joint is Macao. He seems like the type who would enjoy the hustle and bustle of running a business. He has a lot of experience in the guild and is good at dealing with people. He could use his fire magic to cook the burgers in a unique and fast way, adding a special touch to the food at his burger joint.
Perhaps in the fanfiction, there is a traveling burger - making wizard who comes to the Fairy Tail guild. This wizard has the ability to infuse emotions into burgers. So, a happy burger might make the eater feel extremely joyful, while a sad burger could bring out melancholy. The Fairy Tail members are intrigued by this concept and start to explore how these emotion - filled burgers could be used in their daily lives and in battles.
Natsu would be a strong contender. His dragon slayer magic gives him great strength and endurance, and his determination to win would be unwavering.
Natsu would be a likely candidate. He's always up for a challenge and not afraid to take on powerful opponents. He'd probably be the first to rush towards Godzilla, either to fight it or try to befriend it in his own Natsu - like way.
Definitely Gray. Their personalities are quite different. Gray is cool - headed and uses ice magic, while Wolverine is more of a rough - and - tumble fighter. The contrast in their powers and attitudes would lead to some great banter and interesting team - up moments.
Laxus might also be a likely champion. He has lightning - fast reflexes which are crucial in boxing. His confidence and powerful attacks could easily intimidate his opponents. He would be able to deliver strong punches with the added advantage of his lightning - based powers, even if it's a boxing - only tournament, his natural physical abilities would still shine through.
Makarov could be a great teacher. He has a wealth of knowledge and experience in magic. He could teach advanced magic techniques and also lessons about leadership and guild values. He would be strict but also very understanding and always ready to give good advice to the students.
Juvia. Although she is extremely loyal to Gray and Fairy Tail in the original series, in a fanfiction, if she were to misinterpret Gray's actions or words as a rejection of her love, she could become desperate. An enemy could take advantage of her vulnerability and persuade her that Fairy Tail is the reason for her unhappiness. Then she might turn against the guild.
Sasuke and Erza could be a likely pairing. Erza is a strong and disciplined character in Fairy Tail, much like Sasuke in his own way. They could bond over their combat skills and their determination to protect what they hold dear. Another possible pairing is Sasuke and Lucy. Lucy's kind - hearted nature might contrast with Sasuke's brooding personality, and their relationship could be one of growth and understanding for both characters.
Naruto himself could be a good candidate. He's always been about achieving the impossible and his chakra nature could be adapted into Phoenix Slayer magic. His never - give - up attitude would also fit well with the Fairy Tail spirit.
Natsu would be a likely candidate. He's always eager for a fight and his reactions to the intense battles in Death Battle would be interesting.
