Matt: I, the author, own NOTHING about Hetalia. Since there is little about the Nordics (they appear in literally at most 5 episodes, though more for Finland), and little about them in character bios, a lot of what I write on the Nordics is my headcanon. Don't like it? Don't read. ALL FLAMES WILL BE RECIPROCATED. This means that if you flame me, I will flame you back. Don't whine that this is "OOC." As I said before there is VERY LITTLE on the Nordics for me to go off of.
Sweden and Denmark are the 2 main characters, but the other Nordics and Ancient Scandinavia are mentioned.
My inspiration from Sweden comes from the fact that I am actually a lot like what I speculate him to be like, though we are very different in some ways. If you really want to get a good idea of what I think of Sweden as, please see my dA account for him (Ask-Sverige) or my story "Dry Ice, Sweden's Blog."
For Denmark, I use the asshole-oblivious-overprotective-big brother. He's homophobic too, or at least he used to be, but present day he has become a lot more accepting of it. I've never written Denmark before. That said, Denmark's not a bad guy (minus the homophobia, sexism, and probably racism), just wild and energetic.
TL; DR: I don't own Hetalia and most of what I go off of for the Nordics is headcanon because of lack of screen time given and character info.
The fanon name I'm using for Denmark is Mathias Køhler. Sweden's CANON human name is Berwald Oxenstierna. He is also homosexual and in love with Finland in CANON.
Big Brother Denmark and Little Sweden
A long, long time ago, so long ago there were dinosaurs everywhere, okay, maybe not THAT long ago. Anyways, there were 2 nations that happened to be brothers.
The big brother, Denmark, also known as Mathias, was 8; his little brother, Sweden, also known as Berwald, was 3.
Our story starts in a small town in southern Sweden, where Denmark and Sweden lived. Their mother, Ancient Scandinavia, had just passed away.
Denmark sighed forlornly. He was outside their house, staring forlornly into the deep North Sea. He missed his mother already, but he couldn't let his baby brother know. Had to protect his baby brother's innocence after all. But Denmark's little brother was strangely intuitive for such a little kid…
"What's wrong, Big Brother? Where's Mama?" Sweden seemingly obliviously toddled up to his sad older brother, who scooped up the tiny nation and gave him a half smile.
"Mom…went on a trip. She'll be back…eventually." He stuttered nervously.
Sweden frowned. "You said the same thing about my pet rabbit that you accidently killed 3 years ago. Mama's dead, isn't she?"
Denmark twitched. Damn his insightful little brother and his perfect memory.
He swore quietly, only to get a deadpanned stare right back.
The tiny Swede frowned again and said, "Remember what Mama said about swearing Mathias…"
"Oh RIGHT!" Denmark face palmed with the memory, wondering how a child of only 3 human years could be scolding him.
Flashback to when Sweden said his first word
"Mathias!" Ancient Scandinavia yelled at her older son, who had been drawing a battle on a piece of paper, "Come quickly!" She sounded angry; she was using that no-nonsense tone that meant "Come-here-now-or-suffer-the-consequences."
When Denmark entered his little brother's room, he was met with his mother's furious glare.
"What's wro-Oh…" His answer came when his baby brother started babbling again.
"Fuck! Dammit!" Sweden giggled. He didn't understand that what he was saying was a string of bad words.
"Mathias!" The angry Scandinavian loomed over her 6-year-old son. "You were swearing around Berwald! His first word was fuck! No more hanging out at the docks with those older boys!"
"I…uh…I'm sorry! I didn't mean to!" Denmark cried, cowering away from his mother who grabbed him and scoured his mouth out with soap. She gave him a few spankings and left him in his room for the rest of the night.
End flashback
Denmark gulped audibly and followed the Swede inside.
"This is what being married is like, isn't it?" He groaned into his hand.
"I heard that!" Sweden scoffed at Denmark.
"You were supposed to!" Denmark stuck his tongue out immaturely.
Sweden rolled his eyes in response before picking up the broom to sweep.
And thus, the brother nations' distinct personalities already began to form.
