Then there are characters like Lancelot who can be Merlin's loyal friend. He could be the one who stands by Merlin when his magic is discovered or when he is in trouble at school. These characters, with their different personalities, create a rich tapestry of relationships and storylines in Merlin high school fanfiction.
There could also be Mordred as a younger student who looks up to Merlin. He might be a bit of an outcast too because he has some strange abilities. Gwaine could be the class clown who befriends Merlin and is always getting into trouble. Percival could be the gentle giant, an athlete on Arthur's team who also befriends Merlin and protects him from bullies at school.
Sasuke is obviously one of the main characters. He is often the focus due to his popularity from the original source material.
Typically, Merlin is a central character. He's the one with the magic and the kind heart that can potentially break the curse. The Beast is another main character. This could be a character with a tragic past, like a prince who was cursed by an evil sorcerer. In addition, characters like Morgana might also make an appearance. She could either be a hindrance, trying to use the situation for her own gain, or a helper in some unexpected way.
Natsu is often a main character. He's known for his fiery personality and strong magic. Then there's Lucy, a smart and kind - hearted girl. Gray is also commonly seen, with his cool ice - magic and his sometimes - comical rivalry with Natsu. Erza is another mainstay, a strong and strict girl who is respected by everyone.
Often, there are other characters from the original Harry Potter series as well. For example, some fanfictions might include Hermione as a friend or mentor to the descendant. She can use her intelligence to help the main character understand their powers better. And of course, there could be some original characters created specifically for the fanfiction, like a mysterious wizard who also has a connection to Merlin's past.
The students, of course. The popular kids might be vying for the homecoming king and queen titles. There are also the athletes who are focused on winning the game during homecoming.
Often, we also see new characters being introduced. For example, a young sorcerer who Merlin takes under his wing. This new character can act as a sort of foil to Merlin, showing how much he has grown and changed. And sometimes, we might see the return of Morgana in a different form, either as a spirit guiding Merlin or as an enemy he has to face one last time. It all depends on the direction the fanfic author wants to take.
Often, his friends at high school can be important characters too. They might be normal humans who are curious about Gohan's sometimes strange behavior. And of course, his family members like Chi - Chi could make appearances, maybe giving Gohan advice on how to balance school and home life.
Well, obviously Merlin is one of the main characters since it's his birthday that's being forgotten. Arthur is often another main character. He might be one of those who forgets, or he could play a role in trying to make up for the forgetfulness later. Gwen could also be a main character, perhaps being too busy with her own tasks to remember Merlin's birthday.
The main character is Merlin, of course. He is the focus as he is the one with the hidden pain. Arthur Pendragon is a key figure too. Since Merlin is Arthur's manservant, Arthur's actions, words, or even his ignorance of Merlin's true self can be sources of Merlin's pain. Sometimes, the Great Dragon can also be involved. The dragon might be aware of Merlin's pain and offer some cryptic advice that Merlin has to decipher while still hiding his pain from others.
