The beard could change his appearance so much that his friends don't recognize him at first. This could lead to some comical misunderstandings in the fanfiction. For example, Gwaine might challenge him to a fight thinking he's an intruder, or Gaius might think he's a new wizard in town. As the story unfolds, they would then discover it's actually Merlin, and this could lead to a deeper exploration of how appearances can be deceiving.
In fanfiction, Merlin growing a beard could signify a passage of time or a new phase in his life. It might be a symbol of his increasing wisdom or a mark of a more mature and powerful Merlin. Maybe he grows it during a period of isolation, where he has time to focus on himself and his magic, away from the chaos of Camelot.
Well, perhaps the story could be about Percy's journey of self - discovery as he grows a beard. Maybe he starts to look more mature and it changes the way people perceive him in the fanfiction world.
Fans of Percy in the original story would likely be interested. If they love the character, they'd be curious to see how this new aspect of him, the beard, changes his character arc.
Well, perhaps in this fanfiction, Harry grows a beard as a sign of his maturity and the many years of hardships he has endured since defeating Voldemort. Maybe he's living a more reclusive life, away from the spotlight of the wizarding world, and the beard is like a shield from all the attention he used to get. He could be devoting his time to research on ancient magic, and the beard just gives him that wise, old - wizard look.
In a Merlin - joins - the - Avengers fanfiction, there could be some really interesting scenarios. Merlin's magic could add a whole new dimension to the Avengers' battles. He could use his magic to heal the Avengers quickly or create illusions to deceive their enemies. Maybe he'd have some clashes with Tony Stark at first because of their different approaches to problem - solving, but eventually they'd learn to work together.
Well, Merlin might take the baby under his wing and protect it with his magic. Maybe he'd have to hide the baby from those who would use it for evil purposes.
Well, he might show off some really old - fashioned but extremely powerful magic that would shock everyone at Hogwarts. Maybe he'd befriend Harry Potter and teach him some ancient spells that could defeat Voldemort in a whole new way.
One reason could be related to Arthur's relationships. If Arthur has a love interest or close friendships that Merlin wishes he could have with Arthur too. Like, if Arthur is spending a lot of time with a particular noble or a lady, Merlin might be jealous because he wants that same level of closeness with Arthur.
One possibility is that Merlin uses his ancient and powerful magic. He might be able to counter Voldemort's dark spells with his own brand of magic that is based on nature and balance. For example, Merlin could use his ability to control the elements to disrupt Voldemort's attacks.
Well, if Merlin gets drunk in a fanfiction, it could lead to some really interesting character interactions. He might lose his usual inhibitions and act more freely. This could result in him getting into trouble with the court or the knights. He could also make a fool of himself in front of Gwen, which would be quite embarrassing for him later when he sobers up.
