Bug-Eyes is a sharp-eyed trader who sails and does business beside Leif Ericson, the man who freed him and raised him as a son. Born Thorfinn, he was purchased by mistake when Leif took him for the son of Thors, and he later joins the real Thorfinn's voyage to settle Vinland.
In his twenties across most of his appearances, Bug-Eyes cuts a lean figure of ordinary height and weight. Dark blond hair sits in a loose, shaggy tangle, a small beard traces his chin, and the feature that earned his nickname is a pair of unusually wide, staring eyes. He resembles Thorfinn Karlsefni closely enough to be mistaken for him, though his own hair runs a deeper blond and his eyes are blue.
Beyond the bulging eyes he is known for, he owns genuinely keen sight, which pairs with his gifts as a first-rate sailor and a shrewd trader chasing a comfortable, refined life. Blunt to a fault, practical, and prone to clowning, he fires off sarcastic jabs at Leif and his companions and says whatever crosses his mind with no filter, which lands him in friction with the crew. Flashes of sense make him a voice of reason now and then, yet he stays happy to play the fool. Painful memories he simply buries, trusting that time smooths every wound. He shrinks from responsibility and keeps warning the others not to lean on him for anything but seamanship, though in practice he proves invaluable to the settlement, charting Epekwitk and serving as its interpreter.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
When his parents lost their farmland, they sold him off. He was old enough to hold onto the memory but chose to wall it away, telling himself instead that the family had simply been separated somehow. He never crossed paths with them again and has no notion of where they ended up. Leif Ericson bought the boy as a slave, then handed him both his freedom and a fresh start, teaching him trade and the whole craft of the sea. To Bug-Eyes, no one in the world matters more. He signed on for the journey toward Miklagard mainly to see Leif home to Greenland safe, fretting the entire way over the old man's failing health, which is exactly why he opposed pressing on to Vinland.
Bug-Eyes was born with the name Thorfinn, but Leif Ericson bought him by mistake while looking for the son of Thors, who also happens to be named Thorfinn Karlsefni. To avoid confusion between the two, he goes by the nickname Bug-Eyes instead.
Bug-Eyes is around 22 years old at his first appearance in October 1018, and about 25 to 26 years old by 1021.
Bug-Eyes is a sharp-eyed trader and sailor who works alongside Leif Ericson, the man who freed him from slavery and raised him as a son. He later joins Thorfinn Karlsefni's voyage to settle Vinland.
Bug-Eyes earned his nickname from a pair of unusually wide, staring eyes, one of his most distinctive features. He also resembles Thorfinn Karlsefni closely enough that the two are sometimes mistaken for each other, though Bug-Eyes has bluer eyes and deeper blond hair.
Despite insisting he should only be trusted for seamanship, Bug-Eyes proves invaluable to the Vinland settlement, charting Epekwitk and serving as its interpreter. He signed onto the voyage mainly to see Leif Ericson safely home to Greenland.
