#merlin bbc headcanon

[mightybog]

I know I'm not the only one who felt uncomfortable with Merlin's powers to compel dragons against their will, particularly with the show centred on Merlin trying to achieve safety and freedom for magic users.

But what if that power goes both ways? Dragonlords may be able to command dragons, but dragons can steer the course of destiny and absolutely wreck the ship.

What if dragons can cause a person monumental levels of predestined pain and suffering, absolutely crush them with the narrative and make not just their hero's journey, but the realisation of their destiny pure unadulterated hell?

Dragonlords who abused their power technically end up achieving their goals, but it's at so great a personal cost that the dragonlords of old were like "yeah, no, we're not gonna fuck with that. How about we just be friends and respect each other?"

Of course, no one was around to warn our poor boy Merlin. My new HC is that his and Arthur's destiny looked so different to the one he expected, and that he suffered so much loss on the way, because he messed with Kilgharrah.

merlin bbc and harry potter crossover, where merlin comes to teach at hogwarts seemingly just for fun

to see how great the newest generation of warlocks is

yet no one knows that he is only there because at certain hours of the evening the castle looks just like the great camelot that is long destroyed

and this is as close as he gets to the only times he was happy

Merlin, who is so powerful he doesn’t need spells because his magic is instinctual

Merlin, who’s slowly been learning spells from Guius’ book but he finds them difficult and unnecessarily complicated (so he ignores it)

Merlin, who mostly just says what he wants to do and the magic within him lets it happen

Merlin, who ends up writing his own spells in the moment because he’s channeling the magic of the earth in his hands

Merlin, who is the most powerful sorcerer in the world, son of the sky and the sea, the last dragon lord, and a mamas boy

“how did you do that? what spell did you use!”

“idk man, i just wanted the mountain to move so it did”

I have a hc that Arthur just picks Merlin up like a sack of flour whenever and everyone just gets used to it. I mean not a soul mentioned Arthur dragging Merlin out of the throne room in The Witch Finder. I like to imagine that that's just how they are. Merlin starts to pick a fight in the market with a neighboring kingdoms knights? Arthur has an easy solution. Throw that servant over your shoulder and walk away. Is Merlin trying to join a fight with no weapons to protect himself? As soon as your open and the other knights can handle it grab him bridle style and haul ass. Works every time. When this first started Merlin would try and fight back and squirm away but it was no use so he just goes with it now.

What if...Ygraine Returns as a Ghost to Care for Her Son

Servant: Sir, I came to inform you that the knights you sent to battle are all dead.

Uther (sitting on the throne, distracted): Well, send their belongings to their families and tell them they were heroes. And bring more cookies, I'm hungry.

Arthur (six years old, watching the scene with distracted eyes next to a very angry ten-year-old Morgana): Good people die young, so when I grow up, I want to be bad like mom. 😌

Morgana: What are you talking about, Arthur! Your mother was a kind and good woman! Where did you get the idea that she was bad!?

Arthur: Yesterday I heard mom say that her dream was for a manure cart to run over dad so he would die once and for all. 🙂

Morgana (eyes wide in complete shock): Your mother would never say such a thing, Arthur… 🫢

Ygraine (next to Uther, trying to strangle him but unable to because she is a ghost): Don't listen to her, baby, mom hates dad and doesn't support anything he's doing! I still can't believe I married this man, listen to what mom says, Arthur, don't follow in his footsteps!

Arthur (turns to Morgana): Mom just said she hates dad, she's also trying to strangle him, but her hands keep going through his body, I think she's a ghost. 🫠 *slowly losing sanity*

Morgana (realizing that the young prince might be crazy): Arthur, maybe she's just joking…

Ygraine (trying to make Uther trip by stepping on his own cape): I'M NOT JOKING! If I could, I would kill him myself! I just can't because I can't touch him!

Arthur: I don't know if the gods would like so much violence…

Ygraine: The gods don't like your father!

Arthur: Okay… 🙂 *takes a cookie from the tray the servant brought*

hey tumblr. is anyone still actively posting about BBC merlin (and merthur by extension) in 2025?

could you like/reblog this post? I really need some mutuals who are still here <3

Merlin: you're a good horse *kisses*

Arthur: ....

Merlin: hi! You're so smart! *Kisses a dog*

Arthur: Merlin

Merlin: what? Do you also want kisses and get called a good king or something?

Arthur: ...................yes

[chasingwhitebunnies]

Headcanon that Merlin buys a new era-appropriate outfit for Arthur around every decade so he’ll have something to change into, but can never bring himself to throw anything out so he’s just got boxes and boxes of clothes (mostly red) from every decade. Also, he only has Arthur’s fashion sense from the 1500s to go on, so he spends ages choosing the outfits specially and imagining what Arthur would like in the new age because he wants to make his transition as comfortable as possible

[thefabledpheasant]

I fully believe Arthur says Merlin’s name in his sleep regularly. Not everyday, but too often for it to be platonic. Am I supposed to believe that the two times he does it on screen are the only times it has happened?? No.

[marcskywalker]

no you don't understand I'm obsessed with the idea of camelot's land and magic loving arthur.

like, he's literally the son of ygraine and magic, and the prophesied king. they'd be protective of him (I imagine it's how he survived the years before merlin, that and his own skills as a warrior).

when Uther sends a young Arthur out in the storm (as a punishment or some suicidal mission to prove his worth idk uther is a shitty parent), the rain falls softer, the wind is warmer, the branch part and make way for him. that sort of thing

whenever he's truly desperate and heart yearning with his noble intentions, Camelot bends over itself to make it happen for it's son and king

If arthur is fighting out there then the ground is sturdier under his feet, if he is ever injured and down then the air seeps a bit of it's magic into him, if he is ever lost and can't find his way back then the horses find him easily, if he is ever hungry and alone then the animal make themselves easy sacrifice

Arthur is Camelot's son. She would protect him with everything until Emrys comes

Headcanon:

A while ago i saw a post around here that talked about how the hand that was used to catch Excalibur in the final episode was shot with a male hand.

This is right after Arthur dies.

What if the hand that caught it was Arthur's?

Freya may be the lady of the lake, but she got there after she thanked Merlin and died.

There is a moment in which Merlin sees that hand rising, and he gasps, almost as if he recognises something. It could be Freya, it could be Arthur.

...

That would imply that Merlin could visit Arthur at the lake and he probably would and I love that idea very much, thank you.

Merry Christmas everyone. :)

Merlin’s secret headcanons

All of the knights know Merlin has a secret, they don’t all know what it is but they have ideas.

- Lancelot knows that Merlin is a sorcerer, him and Merlin talk about it, he knows about the prophecy.

- Gwaine knows that Merlin is a sorcerer, he also knows that sorcery is illegal and that as a knight he has a duty to turn him in, so he pretends not to know. He also always covers for him when he disappears and Arthur comes to the tavern looking for him.

- Elyan has suspicions about Merlin being a sorcerer (it’s not very well hidden) but is convinced that no one is stupid enough to deliberately practice magic that close to the pendragon so he assumes that Merlin doesn’t know what he’s doing.

- Leon knows for certain that Merlin is gay. He understands it’s frowned upon which is why it’s a secret and that clearly Merlin wants it to be a secret so he doesn’t bring it up but sometimes he worries for the boy’s safety cause he is not hiding it well.

- Percival is pretty sure Merlin has a crush on most of the knights, definitely Lancelot and Arthur, maybe also Gwaine. He thinks that everyone knows he’s gay and that they just don’t bring it up. (He also thinks Gwaine is bi and Arthur is at least a little interested in men).

- Arthur believes Merlin is gay, he also believes Merlin doesn’t know he’s gay. He doesn’t bring it up he’s trying to let Merlin discover himself in his own time though he does something made the odd remark to try and nudge his discovery along a bit. (He also believes Merlin has a crush on him).

omg omg omg

arthur gives merlin his mothers sigil thinking that hes going to die and wants to finally tell merlin how he feels and what better way of conveying the intensity of his emotions and how serious he is other than marriage? merlin accepts the sigil which means theyre married!! yay!! only. they both survive and arthur QUICKLY realizes that merlin has no idea the significance of the sigil. he has no idea theyre married. and arthur has no idea how to tell him bc then he’ll have to explain WHY he gave him the sigil aka WHY HE PROPOSED and now that hes not staring death in the face. he just. cant.

blah blah blah time skip to happy ending

the druids invite arthur and merlin to a celebration of the unification of emrys and the once and future king and the fruition of their destinies. merlin and arthur are excited bc finally peace is here and magic is returning and this can be the next big show of trust and reconciliation between camelot and the druids and so theyre there in the druid camp having fun when theyre approached and asked to participate in the ceremony. theres a huge buzzing crowd watching as the elder druid ties their hands together and goes on and on about the magnificence of two men standing before them and their great destinies and how the two sides of the same coin are joined finally as the prophecy said all those years ago. merlin doesnt realize it was a handfasting ceremony until hes talking to a few of the druids later on

anyway. merthur accidental wedding(s). now they both know theyre married but they dont know the other knows theyre married bc different ceremonies and traditions and all that. arthur is all awkward about it bc hes emotionally constipated. merlin is convincing himself he doesnt have to bring it up to arthur bc its not like the DRUID marriage ceremony is legally binding in camelot. they didnt sign any papers or anything. theyre not really married in camelot so arthur doesnt have to know. and then merlin can selfishly keep this truth close to his heart. even if its not reciprocated.

married life shenanigans ensue. merlin and arthur both have to physically stop themselves from calling the other their husband. jealous spats when out in the tavern or when visiting royals/nobles stop on by. leon knows all and is this close to snapping. extra protective idiots. and idk someone catches merlin holding the sigil and explains the significance of it or a druid asks arthur where his husband emrys is and my boy is STRESSED about being caught but then the druid brings up the handfasting ceremony. stupid idiot x stupid idiot.

you see my vision, right?

[gldnstrngs]

the hc that uther is against magic but isnt a homophobe is genuinely so funny to me like he dgaf that arthur is gay as long as he doesnt end up with a magic user💀

arthur: father, i like men.

uther: [unbothered] okay whatever

[merlin looking flabbergasted in the background]

arthur: … you’re not angry?

uther: no, i don’t care.

uther:

uther: i can excuse you liking men, but i draw the line at you liking magic users!!!!

arthur & merlin: [confused] you can excuse liking men?!?!?!!?

[hey-im-okay]

So do we just all agree that the knights absolute love Merlin the way cat owners love their cats?

Knights, holding up Merlin from under his arms: so this is Merlin and he’s so nice and we love him.

Merlin: *is actively breaking the law by existing* *has literally killed people* *drops branches on peoples heads* *and even tried to kill the king*

Knights: he’s just a funky little guy :)

I would even bet money he knocks glasses off tables when he wants to annoy someone (Arthur-)
