I think Tom Holland could be a great choice. He has that boyish charm and can easily portray a character with a lot of energy, which would be suitable for a young and powerful brother of Merlin.
Maybe Taron Egerton. He has shown his acting chops in various movies and can bring a sense of mystery and strength to the role of Merlin's brother. He can also do a great job of showing the character's growth and development throughout the story.
Ansel Elgort could also be considered. With his tall and lanky frame, he can give an air of otherworldliness. And his acting skills can help him to convey the complex emotions that a character like Merlin's brother would have, whether it's loyalty, jealousy, or heroism.
Another plot could be that Merlin's brother is initially on the wrong side. Maybe he's been influenced by Morgana or some other dark force. But through Merlin's love and persuasion, he eventually sees the error of his ways and joins Merlin in the fight for good.
In this kind of fanfiction, it often reimagines the entire dynamic between Merlin and Arthur. They might have a more equal footing from the start, as brothers. Their relationship could be filled with a different kind of loyalty. Instead of the servant - king dynamic, it could be more of a partnership in ruling Camelot. They would also share family secrets and a deeper bond based on blood.
One suitable character could be a healer's daughter. She has grown up seeing the power of natural remedies and has a natural inclination towards magic. She is kind - hearted and intelligent, which would make her a great apprentice for Merlin. Also, a young noble who has been shunned by his family for his strange dreams (which are actually premonitions due to his budding magic) could be an interesting choice. Merlin would see the potential in him and take him as an apprentice.
Definitely. A lot of fanfiction in this genre plays with the idea of their brotherly bond in different scenarios. You can find ones where they have to protect each other from dark magic or political intrigue. There's this one fanfic where Merlin discovers a new power and Arthur is the only one he trusts enough to share it with, which really shows the strength of their brotherly relationship.
Merlin's magic can both strengthen and complicate their relationship. On one hand, his magic allows him to protect Arthur in ways others can't. For example, he can use magic to heal Arthur's wounds secretly. But on the other hand, Merlin has to hide his magic from Arthur in many fanfictions because of the laws against magic in Camelot. This secrecy can create tension, like when Arthur suspects something is different about Merlin but can't quite put his finger on it.
One common theme is loyalty. Since they are brothers, their loyalty to each other is often a central focus. They will go to great lengths to protect one another.
A possible plotline could be that they discover their brotherhood later in life. Maybe there was some mystery or secret that kept it hidden. This revelation could change the course of Camelot's future as they reevaluate their relationship and roles. Another plotline could involve them facing a common enemy that only their combined strength as brothers can defeat.
Yes, there are likely some fanfictions out there with this concept. Fanfiction writers often come up with creative and out - of - the - box ideas like this. It allows them to explore different relationships and storylines within the magical universes of Harry Potter and Arthurian legend.
Arthur could be the one to spank Merlin. Given their relationship where Arthur is the king and Merlin is his servant, if Merlin does something that Arthur believes is a serious offense against Camelot or his own authority, he might take this rather unorthodox form of punishment. Arthur is known for his hot - headedness and quick decision - making, so in a fit of anger, he could do it.
Maybe Harry would find out about his relation to Merlin through some magical artifact or prophecy. Then they could team up to fight a greater evil that threatens both their worlds.
