Given just the title 'lifts her tail fanfiction', it's really hard to determine the main characters. It could be an original character created for this fanfic. She could be a shape - shifter, and when she lifts her tail, it could be a sign of her about to transform. And there could be other characters who are either trying to help her or stop her from doing whatever is associated with this tail - lifting action.
I don't know for sure as we have so little information. It could be a female character (since it says 'her tail') and perhaps a sidekick or antagonist related to her in some way.
There's no way to tell exactly. But if it's a fanfiction based on an existing work, it might feature characters from that original work who are now involved in a story where this 'lifting her tail' action is important. Maybe it's a princess - like character who has this unique trait of lifting her tail, and there could be a prince or a wizard as other main characters.
I'm not sure specifically as there could be many different 'lifts her tail' fanfictions. It could potentially be about an animal character that lifts its tail in a certain situation, perhaps in a fantasy or adventure setting where this action has some significance.
The main characters are likely Tony Stark, as the title implies he is the one who lifts Mjolnir. And of course, Thor would also be an important character. Since Mjolnir is his weapon, his reaction to Tony lifting it would be a significant part of the story.
The main characters would be Percy and Thor for sure. Percy is the central figure in this scenario as he does the extraordinary act of lifting the hammer. Thor is important because it's his hammer. Additionally, Odin could be a character. As the All - Father in Norse mythology, he would have a great interest in Percy being able to lift the hammer. And from Percy's side, Grover could be there. He might be the one to provide some comical relief during the intense situations that arise from Percy having the hammer.
Steve Rogers could be in it too. He has his own relationship with Tony, and his reaction to Tony lifting the hammer would be interesting. He might see it as a sign of Tony growing as a person and a hero. And perhaps there would be some banter between them about it.
Sting, a confident and powerful mage from Sabertooth, and Lucy, a smart and kind - hearted Fairy Tail member, are the main characters. The fanfiction usually focuses on how their different personalities and magic abilities interact. Sting's more brash and direct style compared to Lucy's more strategic and empathetic approach often creates interesting dynamics in the stories.
Often, the puppies themselves are the main characters. They can be given names like Sparky or Fluffy. And then there are the Fairy Tail mages who interact with them. For example, Erza might be a key character as she could be the one to train the puppies in self - defense. Gray could also be important as he might accidentally freeze the puppies' water bowl during one of his ice - making sprees.
The main characters can also be the magical creatures that exist in the 'Fairy Tail' universe. They might have a special connection to the king, like being his protectors or having a pact with him. For example, a powerful phoenix could be a key character, helping the king in times of crisis or being a symbol of his power and authority.
Well, obviously Jackal is one of the main characters. But often, you'll also see Natsu Dragneel. Since Natsu is one of the main protagonists in 'Fairy Tail', he often crosses paths with Jackal in fanfiction. Another character could be Lucy Heartfilia. Her celestial magic might play a role in a story involving Jackal, like she might use her magic to help defeat him or understand his motives.
The main character is Rolu, of course. But we could also see Wendy in the fanfiction. Wendy might use her healing magic to help Rolu when he gets injured during a battle. Makarov, the guild master, could also play an important role. He might be the one to give Rolu a chance to prove himself in the Fairy Tail guild, and his wisdom could guide Rolu as he navigates the complex world of Fairy Tail and its various challenges.
Another possible main character could be a new character created specifically for the fanfiction who has a deep connection with Ophiuchus. Maybe they are siblings or have a mentor - mentee relationship. This new character can bring a fresh perspective to the story and help drive the plot forward.
