There might also be other supporting characters. For example, AJ's friends like Twilight Sparkle or Fluttershy could make appearances. Twilight might offer some magical advice or knowledge when it comes to dealing with the dragon, and Fluttershy could use her gentle nature to help bridge the gap between AJ and the dragon in case of any misunderstandings.
Obviously, AJ (Applejack) is one of the main characters. She is known for her honesty, hard work, and loyalty in the My Little Pony universe. The dragon is also a main character. It could be a unique dragon with its own personality traits, perhaps being a bit rough around the edges but having a good heart deep down.
Some fanfictions might introduce new characters specifically created for the story. These could be other creatures that live near the dragon's lair or ponies from AJ's family who have different reactions to the presence of the dragon. For example, AJ's little sister Apple Bloom might be curious and want to befriend the dragon, while her older brother Big Macintosh might be a bit more cautious at first.
Samson the dragon is the key character for sure. However, depending on the plot, other characters might include Spike, the baby dragon. Since Samson is also a dragon, there could be some sort of relationship or dynamic between them. And it's also possible that there are original characters created specifically for this fanfiction that interact with Samson, either as friends or foes.
One interesting plotline could be AJ befriending the dragon and they go on adventures together in Equestria, exploring new lands and facing challenges. For example, they might come across a group of mischievous creatures and have to use AJ's honesty and the dragon's strength to solve the problem.
We only know it's called 'aj love story', so the most likely main characters are 'a' and 'j'. They could be two individuals with unique personalities. Maybe 'a' is kind - hearted and 'j' is adventurous, and their personalities play a big role in their love story.
Obviously, AJ is one of the main characters. She is often the center of the action in these fanfictions, with her unique skills and personality. Then there are the members of the Lab Rats Elite Force like Chase, Bree, and Kaz. They usually interact with AJ in different ways, sometimes as teammates and other times as friends or rivals.
It could be Naruto himself. Since it's a crossover, he might be the main character who brings his ninja skills and godlike abilities to the MLP world. Maybe he teams up with Twilight Sparkle, and they become the central figures in the story, with Naruto teaching Twilight about chakra and Twilight introducing Naruto to the magic of Equestria.
Most likely, the changelings would be the main characters. Since it's in the title, they are probably the focus. But it could also include some well - known MLP ponies like Twilight Sparkle or Fluttershy if the story involves the interaction between the changelings and the pony world.
Obviously, Twilight is one of the main characters. And the other main character seems to be the 'me' in the title, which could be a self - inserted character created by the author, perhaps someone who enters the My Little Pony world and has a special connection with Twilight.
The two boys are the central characters in 'Two Gentlemen of Verona by AJ Cronin'. They are the ones who face the challenges of life head - on. Their sister, who is in need of medical treatment, is another important character. The story is about their relationships and how they interact with each other in difficult circumstances. The boys' love for their sister is palpable and it shapes their every action.
AJ Fikry is the central character. There are also other characters like the people in his small town who interact with him, such as his customers in the bookstore and perhaps some local friends or family members, though AJ Fikry is the most prominent.
The main characters are obviously Sunny and Twilight. Sunny is likely to bring her own charm and naivete from her story, while Twilight is the well - known book - smart and powerful alicorn from the main My Little Pony series.
