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.
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. He's got incredible power and determination. His ability to eat fire and use dragon - slayer magic gives him an edge. He's not afraid to take risks and he's always ready for a fight, which would be very useful in the various tasks of the tournament.
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.
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.
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.
Gray is another candidate. Gray's cool and collected demeanor could contrast with Tobi's more mysterious nature. They could get into arguments about the best way to handle a situation, like when facing a powerful enemy. Or, they could find common ground in their skills and work together to protect Fairy Tail from danger.
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.
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.
Natsu from Fairy Tail and Maka from Soul Eater. Natsu is a hot - headed and powerful mage, always eager for a fight. Maka, on the other hand, is a determined Meister with a strong sense of justice. Their common goal of defeating powerful enemies would likely bring them together. Natsu's brute strength and Maka's strategic thinking could make for a great combination in battles.
