Kido could fit in as a new member with a special skill set. He could be a mage with powers that Fairy Tail has never seen before, which would immediately make him an interesting addition.
He might fit in by being a loner who is initially skeptical of Fairy Tail's family - like atmosphere but eventually warms up to it. His character arc could be about learning to trust and rely on others, which is a big theme in Fairy Tail.
Kido could also be introduced as a traveler who has knowledge of a great danger approaching Fairy Tail. He joins the guild to help them prepare for this threat. His outsider perspective could bring new strategies and ideas to the guild, and his journey with the Fairy Tail members to face this danger could be the main plot of the fanfiction.
The talking car in the Fairy Tail fanfiction could be a creation of some mad scientist - type character in the guild. It might have been an experiment gone wrong or right, depending on how you look at it. For example, if it was made by someone trying to combine technology and magic, and it ended up being a talking car. It could then join the guild's adventures, perhaps being used to break through magical barriers with its technological know - how.
He could be a new addition to the Fairy Tail guild. As a baby, he'd bring a lot of innocence and new energy. The guild members would have to take care of him, like how they take care of each other. Maybe he'd be found near the guild's entrance one day, and they'd decide to keep him. His ninja abilities, even at a baby stage, might start to show in small ways, like his speed or reflexes, which could be interesting to the magic - using guild members.
Mirajane could be a key character in a fanfiction where the worlds of Naruto and Fairy Tail are merging. Her strong magical powers would make her a valuable ally. In this merged world, she could help Naruto train to control new types of energy that are a combination of chakra and magic. She could also share Fairy Tail's sense of community and friendship with Naruto and his friends, which would strengthen their bonds and make them more united against any threats.
In a fanfiction scenario of being in Fairy Tail with Kido, there are numerous possibilities. Kido's personality would play a big role. If he's the quiet and mysterious type, it could contrast with the more boisterous members of Fairy Tail. His presence might even inspire some of the younger members to develop new skills. He could participate in the guild's festivals and competitions, showing off his unique abilities. And there could be a whole arc where Kido has to overcome his own past traumas with the help of the Fairy Tail family, creating a deep and engaging story within the fanfiction.
Hollow Ichigo could be a powerful antagonist. His strength and ferocity would make him a formidable foe for the Fairy Tail guild.
Naruto would fit into the Fairy Tail story by being a source of inspiration. His journey from an outcast in his own village to a hero could resonate with some of the Fairy Tail members who have also faced hardships. In battles, he would be a game - changer with his ninjutsu. His presence might also lead to new story arcs, such as when he discovers the similarities and differences between his world's power system and Fairy Tail's magic. He could team up with Natsu and the others, and together they could take on threats that neither could handle alone.
Well, Goku's powers are extremely powerful. In Fairy Tail, magic is the main power source. Goku's ki-based abilities could be seen as a super-advanced form of magic. His super strength, speed, and energy blasts could make him a formidable ally or a terrifying foe. He could easily take on some of the stronger dark guilds by himself. Also, his ability to constantly grow stronger through training would be a unique aspect compared to the mages in Fairy Tail who mainly rely on learning new spells.
Gohan's powers could be a great addition to the Fairy Tail universe. His Saiyan strength and ability to go Super Saiyan would make him one of the most powerful mages in the guild. He could use his ki blasts like powerful magic attacks, and his speed and agility would be useful in battles against dark guilds.
Tsuna in Fairy Tail fanfiction? He would be a great addition. His character is all about growth and adaptation, which is a big part of the Fairy Tail spirit. He could start as an outsider, just like how some characters join the guild later. His unique powers would surely attract attention. The Fairy Tail guild is known for accepting different types of magic and people. Tsuna's kind heart and his determination to protect his friends would resonate with the guild members. And his journey to become stronger could be intertwined with the various storylines and adventures already present in the Fairy Tail world.
As the master, Naruto's abilities would have a significant impact. His shadow clones could be used for strategic purposes, such as distracting enemies while the real members of Fairy Tail launch a surprise attack. His Sage Mode could be used to sense the presence of hidden enemies or magic traps. And his unique ninja skills like tree - walking and water - walking could be adapted into training exercises for the Fairy Tail members to improve their control over their magic. His Nine - Tails chakra could also be a powerful asset, perhaps used as a last - resort power - up in critical battles.
