Well, an unlikely alliance in this fanfiction could be between Ben and Natsu. Natsu is all about fire and brute force, while Ben has his various alien forms with different abilities. They could initially clash due to their different approaches to fighting, but then realize that together they can be much stronger. For instance, if Ben transforms into an alien with wind - based powers, he could enhance Natsu's fire attacks.
An interesting aspect of a Ben 10 and Fairy Tail fanfiction about unlikely alliances could be the pairing of Ben's more tech - savvy alien forms with the magic - centered Fairy Tail world. Maybe Ben's alien form that can manipulate technology teams up with Levy, who is a bookworm and expert in magic scripts. They could come up with some really unique ways to defeat enemies. Ben could use his alien tech to analyze and counteract dark magic, while Levy uses her knowledge of magic to enhance Ben's tech's effectiveness.
In a story of unlikely alliances in Ben 10 and Fairy Tail fanfiction, we could see an alliance between Ben when he transforms into an alien with healing abilities and Wendy from Fairy Tail. Wendy is a Sky Dragon Slayer with healing magic. Together, they could form a sort of mobile medical unit in the middle of battles. They could also learn from each other's healing techniques, Ben from his alien biology and Wendy from her dragon - taught magic. This would not only be useful for their own side but also for any civilians caught in the crossfire.
A simple alliance in this fanfiction could be between Shiemi Moriyama and Lucy Heartfilia. Shiemi could use her knowledge of plants and herbs, which might be useful in creating potions or antidotes in the Fairy Tail world. Lucy, with her celestial spirits, could provide protection for Shiemi when they encounter demons.
A simple alliance in this fanfiction could be that Baiken helps Naruto with her sword skills. Naruto is mainly a ninjutsu user, so her sword - based combat knowledge could be a great addition to his fighting repertoire.
Another aspect in a fanfiction could be their cultural differences. Naruto comes from a world of ninjas with strict honor codes, while Shego is from a more modern - ish world with different moral values. This could lead to many comical or thought - provoking situations. For instance, Naruto might be shocked by Shego's casual attitude towards stealing or using underhanded means in combat. However, as they spend more time together, they begin to see the value in each other's perspectives. They might even influence each other's ways of thinking and acting, with Naruto making Shego more empathetic and Shego teaching Naruto to be a bit more flexible in his approach to problems.
A fanfiction could also explore the idea of Starkiller and Ahsoka meeting in a post - Empire world. Starkiller, having broken free from his Sith past, and Ahsoka, who has seen so much of the galaxy's turmoil, could join forces to help rebuild and protect the newly - emerging peaceful systems. They would have to overcome their differences, as Starkiller has a more aggressive style while Ahsoka is more in tune with the Jedi's peaceful ways. But their shared goal of a better galaxy could bring them together. They could start by training a new generation of Force - sensitive beings, combining their unique teachings to create a more balanced approach to the Force.
In fanfiction, Neji and Sakura could form an unlikely alliance against a common foe within the Hidden Leaf Village. This could be due to some political intrigue where they have to trust each other despite their different personalities.
Another interesting alliance could be between Ron and Keroberos. Ron, with his love for food, might be constantly bribing Keroberos with treats to get information about the Clow Cards or to ask for his help in some comical situations. Keroberos, being a bit of a glutton himself, would be easily swayed by Ron's offerings.
A simple fanfiction plot could be that Peter accidentally stumbles into Wakanda while on a mission. Shuri finds him and at first is suspicious. But then she realizes his good intentions. They start to exchange ideas about technology and hero - work.
In some fanfictions, there could be a time - travel element. What if Draco and Hermione are sent back in time? They might have to work together to ensure the future they know doesn't change. This could lead to some interesting character development as they are forced to rely on each other in a completely different time period, and they may see each other in a new light as they face challenges together.
Perhaps the fanfiction focuses on a parallel universe where Snape, Harry and Lucius are all on the same side from the start. They are part of a secret group that is trying to reform the wizarding world's education system. Their different perspectives - Snape's strictness, Harry's compassion and Lucius' cunning - combine to create a powerful force for change.
Well, in such a fanfiction, they could team up against a common enemy. Maybe an ancient dark force that has been awakened in both their times. Their combined knowledge of magic from different eras would be a great asset.
