In the original, the focus is on Merlin's journey to help Arthur build Camelot. In Dark Merlin fanfiction, the focus might shift to Merlin's own power - seeking and self - centered goals. For example, he may use his magic for personal gain rather than for the good of Camelot. It's a big shift in the narrative.
Well, in the original Merlin series, Merlin is mainly a hero. But in Dark Merlin fanfiction, he becomes the antagonist or at least a morally ambiguous character. His actions and motives are often much darker.
In 'badass Merlin fanfiction', Merlin is often more assertive. In the original series, he had to hide his magic a lot. But in fanfiction, he can be bold with his powers. For example, he might openly use magic in Camelot without fear. Also, the relationships in fanfiction can be more intense. His friendship with Arthur could be more of an equal partnership in terms of power, rather than Merlin always being in a subservient role.
In the original Merlin story, his magic is just one part of him, but in the fanfiction 'merlin is magic itself', it becomes his central essence. This changes the way his character is perceived and the role he plays in the story.
If Merlin is a Dark Lord in fanfiction, it could be an interesting exploration of the 'nature vs. nurture' concept. Maybe he turned dark because of the constant fear of being discovered and persecuted for his magic. His actions as a Dark Lord might include taking over Camelot or exacting revenge on those who wronged him in the past. It gives a whole new perspective on his character.
He could become a Dark Lord due to betrayal. If someone he trusted deeply, like Arthur perhaps, turned on him because of his magic, it might push him over the edge.
In Royal Fem Merlin fanfiction, Merlin is female, which changes the power dynamics and relationships. For example, her interactions with Arthur might have a different romantic or platonic undertone. Traditional fanfiction usually follows the male Merlin's story.
The plot structure might be different. Other Merlin fanfictions could follow the general storyline of the show, with Merlin helping Arthur and dealing with the usual villains. However, 'not just a servant' might have a completely different plot. It could be centered around Merlin's own adventures, independent of Arthur, or it could be a story that rewrites the entire Camelot mythology from a new perspective with Merlin at the center in a non - servant role.
Merlin in fanfiction may also have different relationships. She could be closer friends with certain characters or have a romantic interest in someone unexpected. For instance, she might form a strong bond with a minor character from the series, which then changes the whole dynamic of the story.
In a more humorous take on the 'Merlin tied to a bed' fanfiction, it could be that Merlin has fallen ill and the overly - protective Gaius has tied him to the bed to make sure he rests. Merlin, being the active person he is, complains constantly. Arthur comes to visit and teases Merlin about finally being still for once. Meanwhile, Merlin tries to convince Arthur to let him loose, promising that he'll be fine. Eventually, Gaius relents and unties Merlin, who then immediately starts bustling around the room.
It could be for comedic effect to lighten the mood and add some fun to the story.
If Merlin died in the fanfiction, it could trigger a series of tragic events. The balance of power could tip, and the villains might seize the opportunity to attack. It could also bring out hidden strengths in the remaining characters as they try to cope with the loss.
