Description
Sweden stands tall and physically imposing with light blond hair and turquoise or blue-green eyes, frequently wearing thin rectangular glasses. His height measures approximately 181-184 cm, making him the tallest Nordic character. He possesses a muscular build and an intense, often menacing, facial expression—shared with Germanic counterparts like Prussia and Germany. His signature attire consists of a long blue naval overcoat from the 1920s, a matching hat, black shirt, tie, pants, gloves, boots, and a Nordic Cross necklace. Early anime versions briefly depicted him with brown hair and eyes before aligning with the manga's blond hair and turquoise eyes.

Historically, Sweden was a formidable Viking warrior hailed as "The Conqueror of the Baltic Sea," "The Lion of Northern Europe," and "The Supreme Ruler of Scandinavia." He once defeated seven nations single-handedly with Finland as his only ally. His past includes rebellion against Denmark's rule, escaping alongside Finland, marking the start of their enduring cohabitation. Following the Swedish Empire era, he embraced military neutrality, shifting focus toward welfare and social programs, reflected in his modern avoidance of conflicts.

Exceptionally taciturn, Sweden rarely speaks, communicating in truncated words or grunts, a trait linked to his cold-climate origins. He prefers actions over dialogue, using a Tōhoku dialect in Japanese. Despite his intimidating exterior, he is inwardly playful, kind, and emotionally sensitive—easily embarrassed and prone to shyness. He channels creativity into furniture making, glass crafting, sewing, and art. His canned surströmming is humorously noted as a potential lethal weapon. Intriguingly, he enjoys debates and arguments despite his silence.

His relationships are complex and pivotal. With Finland, a bond formed through their joint escape from Denmark; Sweden openly calls Finland his "wife," though Finland rejects the label. They cohabitate, adopt a dog named Hanatamago, and show mutual care—Sweden alters his old clothes for Finland due to their height difference, and Finland overcomes initial fear to admire him. Sweden adopted Sealand after winning an online auction as the sole bidder. He struggles to connect with Sealand, who prefers video games, leading Sweden to invent the "Dambolis" (a box labeled "England") to engage him. Ladonia, a micronation on his territory, acts like a spoiled child, knocking him down during tantrums; Sweden humors him by pretending defeat in scripted play-fights. His dynamic with Denmark evolved from violent historical conflicts like the Great Northern War to a modern "best buds" relationship. Others, like Estonia and Prussia, react fearfully to his glare—Prussia faints repeatedly during encounters, haunted by wartime memories.

Sweden appears across multiple media. Manga stories include *Running Away With Mr. Sve*, *Su-san and the Dog*, *Polish-Swedish Wars*, and *The Creation of Dambolis*, depicting his past with Finland, daily life, and parenting Sealand. In anime, particularly *The World Twinkle*, he features in Nordic-centric episodes like "Meeting of the Nordic" and "The Nordic Five +α," adapted from *Hetalia: Axis Powers* Volume 6, plus the DVD-exclusive "The Ruler of Scandinavia and The King of Eastern Europe." His character songs, such as "Mm." (*ん。*) from *The World Twinkle Character CD Vol. 4*, reflect his minimal speech.

Trivia notes include his canonical homosexuality with romantic feelings exclusively for Finland, and his birthday aligning with Sweden's National Day (June 6). His human name, Berwald Oxenstierna, references composer Franz Berwald and the noble Oxenstierna family.
