Well, perhaps the story could start with the Fairy Tail gang getting teleported into the Minecraft world. They don't understand the rules at first. Erza would take charge, trying to figure out how to get resources. She discovers that her armor gives her certain advantages, like being able to break stone more easily. Meanwhile, Happy could fly around and scout for rare materials. As they progress, they face challenges like getting lost in huge cave systems and having to rely on each other's skills to find their way out.
I think Gray would be quite skilled. His ability to create and manipulate ice could be very useful in Minecraft. For example, he could use his ice to create platforms over lava or to quickly build structures in cold biomes. Also, he's very calm and strategic, which would help him plan out his builds and mining routes effectively.
One possible plot idea could be that the characters from Fairy Tail are transported to the Batman universe. Natsu, with his fire - based magic, might be seen as a new and unpredictable force in Gotham. He could team up with Batman to fight against a common enemy like the Joker, who has somehow gotten hold of some magical artifacts from Fairy Tail's world. The contrast between Batman's dark and brooding nature and Natsu's hot - headed and impulsive personality would create interesting dynamics.
One idea could be that the Fairy Tail guild members play a magical board game. In this game, different squares on the board represent various challenges like fighting a powerful dark wizard or solving a complex magic riddle. Natsu might rush in headfirst, getting into all sorts of comical situations as he tries to win the game using his brute strength instead of strategy.
Well, perhaps the bet could be about a race. Bacchus bets that he can run faster than a particular Fairy Tail mage. In the process of preparing for this race, the Fairy Tail mage discovers some new abilities within themselves. And as they compete, it's not just about winning the bet but also about the respect and honor of their respective guilds. This could also show how different the cultures of their guilds are when it comes to competition.
Well, perhaps there could be a situation where an evil force in the Fairy Tail universe is creating portals to other dimensions to gather powerful allies. Deadpool accidentally stumbles through one of these portals. The Fairy Tail guild has to figure out how to deal with this strange, talkative, and unpredictable new 'ally'. Deadpool, on the other hand, is just excited to be in a new world full of magic and new things to fight. He could end up teaching some of the Fairy Tail members his unique combat moves, while also learning some magic from them in return.
A plot could involve a magic competition in the Fairy Tail guild. Mirajane and Freed both enter. Mirajane wants to show off her new transformation magic, and Freed aims to prove the power of his rune magic. As they compete, they start to learn from each other. Mirajane might pick up on Freed's precise and calculated approach to magic, while Freed could be inspired by Mirajane's bold and fearless use of her powers. This could lead to a friendly rivalry that also strengthens their bond within the guild.
A cool plot might be that a powerful dark wizard in the Fairy Tail world discovers a way to control some of Ben's aliens. Ben has to seek help from Fairy Tail mages to break the control and then they join forces. The Fairy Tail members are amazed by Ben's ability to transform and his alien powers, and they work together to stop the dark wizard's plan to take over both worlds.
One idea could be that your OC is a powerful mage with a unique magic ability, like the power to control time on a small scale. They join Fairy Tail and at first are an outcast because of their strange magic. But during a big battle against a dark guild, they use their time - control magic to freeze the enemy mages for a short while, allowing Fairy Tail to win. This earns them respect and they become an important part of the guild.
A cool plot might be that a dark wizard from Fairy Tail discovers a spell that can open portals to other dimensions and accidentally pulls Inuyasha, Kagome, Shippo, etc. into their world. The Fairy Tail guild decides to help them get back home. But during this time, they realize that there are some similarities between the demons in Inuyasha's world and the dark creatures they fight in their own world. So, they team up. Inuyasha and Natsu could have a friendly rivalry over who is stronger and in the end, they combine their powers to defeat an ancient evil that was awakened by the portal - opening spell.
Perhaps in a 'Fairy Tail Infinity War' fanfiction, the Fairy Tail guild teams up with other magic guilds across the land. They face an enemy who has acquired the power of the Infinity Stones and is using it to corrupt magic. The story could follow the journey of different characters like Lucy, who tries to use her celestial spirit magic to counter the Infinity Stone - based attacks, and Gray, who has to freeze the chaos caused by the stones.
