Background / History

White Wax Island

Barlow was the second child of Marcus’s household. From childhood, he collected old newspapers and read them alone, an early sign of his interest in information and the wider world. 17

Before adopting the Uchiha name, he worked for local fishmongers, running errands and maintaining their accounts. Alongside his siblings, he secretly trained swordsmanship and chakra cultivation from memories left by a mysterious dream. 4 16

After Roy recovered a cracked jade Tomoe from the beach, Barlow immediately judged it unusual and ordered that it be kept hidden from outsiders. He later safeguarded the weapons, money, compass, and sea chart Roy took from pirates, concealing the dangerous items and directing that the Beli be spent gradually. 2 6

Departure and the Uchiha Trading Company

Following Marcus’s declaration that the family would bear the Uchiha name, Barlow left White Wax Island with Damian, Roy, and Mila aboard their father’s white waxwood sloop. He navigated with his own sea chart and proposed building a trade operation through Orange Town, purchasing discounted goods for resale across the Konomi Archipelago. 17 18

In Orange Town, Barlow used ledgers, local intelligence, and careful financial planning to establish a foothold at the docks. After the Red Skull Tavern conflict and the destruction of the Sea Serpent Gang, he accepted Koldo’s service and built the Uchiha Trading Company into a major maritime power. 20 25 38

He later negotiated a trade and marriage alliance with the Capone Family, securing West Blue port access, commission exemptions, and exclusive East Blue representation for West Blue specialties. 55 57

Appearance

Barlow is a lean, sharp-featured man whose appearance became increasingly severe as his responsibilities grew. By the time he led the trading company, he was taller and broad-shouldered, though later intensive work and irregular meals left him visibly thinner. 38 86

  • Habitually furrowed brows, a high brow ridge, and deep-set eyes that make him appear constantly calculating. 38
  • Usually wears dark, unmarked business clothing, including a dark blue coat or dark shirt. 38 117
  • Carries a straight, guardless sword with a plain sheath and a grip polished smooth through use. 38
  • Has faint old knife scars across his forearms. 117
  • Uses desert travel gear—including a cloak, goggles, and waterskin—while operating in Alabasta. 103

Personality

Barlow is reserved, analytical, and ruthlessly practical. He treats ledgers, maps, contracts, and battlefield reports with the same focus, often processing emotional or dangerous situations through logistics and calculation. His ambition drove him to turn Orange Town into the foundation of a trade network spanning the East Blue, West Blue, and the first half of the Grand Line. 38 55 82

He remains calm under pressure and gives concise orders without theatricality. During the Raging Lion Pirates’ attack on Orange Town, he refused to waste patrol forces in a doomed dockside engagement, instead assigning them to defend the company archives, warehouses, and town hall. 67

His control can become harsh. When Roy attempted to leave the house under improper circumstances, Barlow physically disciplined him, though he deliberately held back enough to avoid lasting injury. 100

Marcus regarded Barlow as the family’s smartest and most ambitious child, but worried that he isolated himself behind his work and refused to share his burdens. 78

Sharingan

Barlow possesses a Three-Tomoe Sharingan, which he awakened in combat at the Red Skull Tavern. 23 54

  • Uses Uchiha Style: Moonfall, a short vertical finishing strike intended to defeat wounded opponents still capable of defending themselves. 72
  • Demonstrates stealth-killing capability, using shuriken, caltrops, distractions, and precise knife attacks while infiltrating Katya Town. 107

Strategy and Command

Barlow combines commercial planning with military decision-making.

  • Reviews contracts personally and enforces breach penalties without compromise. 86
  • Secured the Capone alliance by matching Uchiha distribution routes with Capone-controlled West Blue supply chains. 55

Story Role / Major Arcs

Orange Town Expansion

Barlow led the siblings’ move into Orange Town, where he planned their first warehouse, market stall, and trade operations. When the Sea Serpent Gang attempted to exploit the newcomers, he entered the Red Skull Tavern, fought through its members, and awakened his Sharingan. 20 22 23

He subsequently turned dockside intelligence, commercial contracts, and the former gang’s territory into the basis of the Uchiha Trading Company. 25 31

Uchiha–Capone Alliance

When the Capone Family came to reclaim Gwendoline, Barlow saw through their adviser’s deception and forced a direct meeting with the Godfather. He negotiated the resulting East Blue–West Blue alliance around shared port access, supply chains, and Uchiha-controlled distribution. 52 55

Raging Lion Pirates War

As president of the trading company, Barlow organized Orange Town’s defense during the Raging Lion Pirates’ assault. He personally confronted Dean, a former Marine major and pirate vice-captain, defeating him with Moonfall while preserving the town’s command structure through disciplined redeployment. 67 72

After Marcus died defending White Wax Island, Barlow mourned with his siblings and received Marcus’s final warning against sacrificing himself to work and isolation. 77 78

Alabasta Rebellion

Barlow treated the Alabasta rebellion as both a threat to Uchiha assets and an opportunity to reshape the kingdom’s power structure. He traveled with Roy and Mila, gathered intelligence from occupied settlements, defeated rebel units at Limestone Village and Katya Town, and offered the Nefertari royal family Uchiha supplies, forces, and intelligence. 102 104 106 110 112

After exposing King Wolof’s deception regarding Prince’s survival, Barlow negotiated broad trade privileges, military authority, compensation, and a marriage alliance with Lia in exchange for Uchiha support. 114 117
