The key characters are Spike and his parents. But considering Spike's life in Ponyville, characters like Applejack, Fluttershy, Pinkie Pie, and Rainbow Dash could also make an appearance. They might be curious about Spike's family or be there to celebrate the reunion. Also, any other dragon characters that are related to Spike's parents or part of their backstory could be part of this fanfiction.
Obviously, Spike is one of the main characters. His parents would be the other important characters. And depending on the plot, Twilight Sparkle or some of Spike's other friends in Ponyville might also be involved, perhaps as moral support for Spike during the meeting.
In this fanfiction, Spike might have an emotional reunion with his parents. He could learn about his family's past and heritage. Maybe his parents would be proud of how he has grown up in Ponyville.
Obviously, Natsu himself would be one of the main characters. His parents, whose identities are likely to be revealed in the fanfiction. There could also be his friends, like Lucy, Gray and Erza. They might be there to support Natsu during this emotional encounter or play a role in helping him find his parents.
In this fanfiction, Kid Goku is a given. His parents are the central focus of the meeting. However, we could also see other Saiyan characters. Maybe some Saiyan elders who knew his parents well and can provide more context about Goku's family. Additionally, Master Roshi could be included. He has been an important figure in Goku's life, and his reaction to Goku meeting his parents could add an interesting dynamic to the story. There could also be villains who try to disrupt the reunion, adding some action and conflict to the fanfiction.
Obviously, Batman himself would be one of the main characters. And of course, his parents, Thomas and Martha Wayne. There could also be Alfred, as he is an important figure in Batman's life and might play a role in facilitating the meeting or providing some insights afterwards.
Obviously, fem Naruto herself is a main character. Her father, Minato Namikaze, and her mother, Kushina Uzumaki, are the ones she is going to meet. There might also be other characters from the Naruto universe like Jiraiya, who was Minato's teacher and could potentially be involved in the story, perhaps as someone who helps facilitate the meeting.
Obviously, Wade would be one of the main characters. And then there would be the parents of the Avengers. For example, Thor's father Odin (if he's still alive in the context of the fanfiction), or Tony Stark's father Howard Stark if he were to be involved in some sort of flashback or time - travel scenario.
Spyro and Twilight Sparkle would be likely to interact. Twilight is very intelligent and well - versed in magic, and Spyro has his own dragon powers. They could learn from each other. For example, Twilight could study Spyro's dragon magic, and Spyro could learn about the complex magic system in Equestria from Twilight.
Applejack and the Heavy might be the first to interact. Applejack is a hard - working and practical character. The Heavy is a no - nonsense fighter. Applejack might see the Heavy and be curious about his large size and strange weapon. The Heavy, on the other hand, might be interested in Applejack's farming skills and the fresh apples she might be carrying. Their down - to - earth personalities could lead to an initial interaction.
Spike's parents in fanfic can be important for filling in gaps in his backstory. Since the show doesn't fully explore his family origins, fanfics can create a more complete picture of where he comes from.
Often in these fanfics, the story of Spike's parents can be intertwined with the overall lore of Equestria. For example, they could have been involved in some long - forgotten battle or event that led to Spike's unique situation in the show. Maybe they had a special mission that was cut short, leaving Spike to be found by Twilight and the others.
