The Ranking

10. Roronoa Zoro

Zoro‘s tragedy is unique on this list because it stems not from systemic abuse or genocide, but from the brutal randomness of fate. His entire life’s ambition is forged from a promise to his childhood rival, Kuina, a prodigy he could never defeat in 2,000 duels. She was the one person who shared his dream of becoming the World’s Strongest Swordsman, yet she was held back by her own belief that her gender would ultimately be a barrier to her goal. After Zoro challenges her to a final duel with real swords, they make a vow: one of them will achieve their shared dream.

The very next day, Kuina is dead. She wasn’t defeated in a glorious battle or taken by a fearsome villain. She died by falling down a flight of stairs. What makes this so haunting is its shocking mundanity. This seemingly “stupid” death is not a flaw in the writing; it is a profound thematic statement that shapes Zoro’s entire philosophy. It taught him a brutal lesson at a young age: the world is not fair, and death is not always a grand, honorable affair.

Strength isn’t just about overpowering an opponent; it’s about becoming so powerful that one can defy a cruel, arbitrary fate that can strike anyone down at any moment. Inheriting her sword, the Wado Ichimonji, Zoro carries not just his own ambition, but the weight of a promise to a friend whose potential was stolen by chance. This early, harsh lesson in powerlessness is the origin of the “King of Hell,” a man obsessed with becoming strong enough to control his own destiny.

9. Sanji Vinsmoke

Sanji‘s story is a tale of two distinct hells: the cold, calculated cruelty of his royal family and the desperate, primal horror of starving to death on a desolate rock. This combination of psychological and physical torment makes his one of the most layered tragic backstories in One Piece. Born a “failure” in the Vinsmoke family, a dynasty of genetically engineered super-soldiers, Sanji was deemed worthless by his father, Judge, for possessing empathy.

He endured relentless bullying from his emotionless brothers and was eventually disowned, locked in a dungeon with an iron mask to hide his existence from the world. His only light in this darkness was his kind mother, Sora, and his sister, Reiju, who ultimately helped him escape his gilded cage. He fled to the sea, only to find a different kind of torment. After a shipwreck, he was stranded with the pirate Zeff. The manga depicts a horrifying truth censored by the anime: Zeff gave all the food to young Sanji while pretending to have his own share. To survive, Zeff smashed and ate his own leg.

This act of profound sacrifice from a man who was, moments before, an enemy, became the bedrock of Sanji’s core values: never to refuse a hungry person and to cherish those who show true kindness. Sanji’s past is a powerful examination of fatherhood. His biological father, Judge, tried to erase him for being human, while his surrogate father, Zeff, sacrificed a part of himself and his dream to save him. It is a definitive statement that family is not defined by blood, but by love and sacrifice.

8. Nami

Nami’s tragedy is a story of prolonged psychological torment and crushing isolation. After being adopted as a war orphan by the Marine Bellemere, she lived a poor but happy life with her sister Nojiko. This peace was shattered by the arrival of the fish-man pirate Arlong. In a pivotal moment, Bellemere is forced to choose between paying for her own life or acknowledging her daughters. She proudly declares them her children, a choice that costs her life as Arlong shoots her in front of Nami and Nojiko.

What followed was a unique form of torture. Arlong, recognizing Nami’s talent for cartography, enslaved her, forcing her to use her greatest passion to draw maps for the very man who murdered her mother. He then weaponized her hope, striking a cruel deal: if she could bring him 100 million berries, he would free her village. For eight years, this sliver of hope forced Nami to participate in her own subjugation, becoming a master thief who betrayed others to save her home.

The true horror of her situation was not just the physical chains, but the psychological prison built from false hope. When Arlong inevitably betrays the deal, her breakdown—stabbing the Arlong tattoo on her arm and finally crying out for help—is one of the most earned emotional releases in the series, making it one of the most unforgettable One Piece saddest moments.

7. Tony Tony Chopper: The Monster Who Just Wanted to Be Loved

Chopper’s story is one of absolute rejection from all sides. Born with a blue nose, he was cast out by his own reindeer herd. After eating the Human-Human Fruit, he became a “monster” in the eyes of humans, feared and hunted. His profound loneliness only ended when he was taken in by Dr. Hiriluk, a quack doctor with a heart of gold who became the first person to ever show him kindness. Hiriluk taught him about the beauty of a pirate’s Jolly Roger as a symbol of conviction and shared his impossible dream of making cherry blossoms bloom on a frozen island.

The tragedy of this tale stems not from malice, but from pure, misguided love. With Hiriluk dying from a fatal illness, Chopper desperately searched for a cure. Misinterpreting the skull-and-crossbones symbol on a poisonous Amiudake mushroom as a sign of pirate-like vitality, he embarked on a perilous journey to retrieve it for his mentor. Hiriluk, seeing the battered and bruised Chopper and knowing full well the mushroom was deadly, ate it without hesitation, moved to tears by his adopted son’s love.

To spare Chopper the guilt, Hiriluk then gave his iconic speech about when a man truly dies before taking his own life in a grand explosion. This devastating outcome, born from Chopper’s first true act of love, created a deep-seated fear that his actions could cause harm, explaining his initial self-doubt and making this one of the most heartbreaking One Piece saddest moments.

6. Señor Pink

Señor Pink is the quintessential example of Eiichiro Oda’s ability to hide profound tragedy behind a bizarre gag. Introduced as a strange antagonist in the Dressrosa arc—a burly, mustachioed man who inexplicably dresses in a baby’s bonnet and sucks on a pacifier—his true story is one of quiet, unending grief. In his youth, Señor Pink was a suave gangster who fell in love with a woman named Russian who despised pirates. To be with her, he lied, claiming he worked at a bank.

This lie led to a cascade of tragedy. While he was away on a mission with the Donquixote Pirates, their infant son, Gimlet, died of a fever. When he returned, a grief-stricken Russian discovered his lie and ran from him, only to be caught in a landslide that left her in an unresponsive, vegetative state. One day, in a moment of desperation, Señor Pink put on his late son’s bonnet, and for the first time since the accident, Russian smiled.

From that day forward, he wore the baby outfit constantly, enduring the mockery of his comrades and the world, all for the chance to see his beloved wife smile again. His “hard-boiled” persona and refusal to dodge attacks in his fight with Franky is a performance of masculinity, but his true strength—his true manliness—is revealed in his willingness to look utterly foolish as a daily, private ritual of devotion to the woman he loves.

5. Brook

Brook’s story explores the psychological horror of extreme and prolonged isolation. Fifty years before the main story, he was the musician of the Rumbar Pirates, a lively crew who befriended a baby whale named Laboon at the entrance to the Grand Line, promising to return for him after circumnavigating the globe. This promise would become the sole anchor for Brook’s sanity.

In the treacherous Florian Triangle, the entire crew was struck down by poisoned weapons. In their final moments, they gathered their remaining strength to perform their favorite song, “Binks’ Sake,” one last time, recording it on a Tone Dial to deliver their message of love to Laboon. The scene of the musicians falling one by one, the sounds of their instruments dropping out until only Brook’s violin remains, is one of the most iconic One Piece saddest moments.

Thanks to his Revive-Revive Fruit, Brook’s soul returned, but it wandered for a year in the fog before finding his body, which had decayed into a skeleton. He then spent the next fifty years completely alone, a living ghost on a ship of his dead friends, his mind fraying in the silent darkness. This is one of the most haunting tragic backstories in One Piece because it deals with a fate arguably worse than death: an eternity of loneliness with nothing but ghosts and a promise.

4. Kyros

Kyros suffers a uniquely cruel fate that transcends mere death: complete erasure from existence. Once the undefeated champion of the Dressrosa colosseum, he found love with Princess Scarlett, and together they had a daughter, Rebecca. Their happiness was destroyed during Doflamingo’s takeover of the kingdom. In a desperate attempt to save King Riku, Kyros charged at Doflamingo, cutting off his own leg to escape his chains. But before he could land a blow, he was touched by the executive Sugar and transformed into a one-legged toy soldier.

Instantly, he was wiped from the memories of everyone he knew and loved. This led to the most devastating of the One Piece saddest moments: as a forgotten toy, he was forced to watch his wife, Scarlett, be shot and killed by Diamante. She died in his arms, not recognizing him, asking this strange toy to tell her husband she loved him.

Powerless and unable to even feel her warmth, he then had to raise his own daughter, Rebecca, as a stranger. She grew up never knowing her father was right beside her, even resenting the “toy soldier” for failing to save her mother. This is a terrifying exploration of identity and memory, forcing a hero to be a ghost in his own life, present for every painful moment but recognized by no one.

3. Nico Robin

Nico Robin‘s backstory is a story of state-sanctioned genocide. The island of Ohara, her home, was a community of scholars whose only crime was the pursuit of knowledge—specifically, the forbidden history of the Void Century contained on the Poneglyphs. For this, the World Government enacted a Buster Call, an overwhelming military assault designed to wipe an island off the map.

As an eight-year-old child, Robin, who was already an outcast due to her Devil Fruit powers, briefly reunited with her long-absent mother, Nico Olvia, only to watch her die in the flames of the burning Tree of Knowledge. Her only other friend, the giant Jaguar D. Saul, sacrificed himself to ensure her escape, begging her to find friends who would protect her. She was allowed to live only by the whim of a young Aokiji, but this mercy was a curse.

Branded the “Demon Child,” an 8-year-old Robin had a 79 million berry bounty placed on her head, condemning her to a 20-year life on the run. She was constantly hunted and betrayed by everyone she tried to trust, forcing her to become cold and manipulative simply to survive. Her tragedy is not just personal; it is symbolic of the series’ core conflict—the fight for truth against a tyrannical power that would rather burn history than allow it to be known. Her iconic cry of “I want to live!” at Enies Lobby is the culmination of this immense suffering, a defiant roar against a world that wanted her very existence erased.

2. Trafalgar D. Water Law

Trafalgar Law’s story combines the creeping horror of a plague with the sudden brutality of extermination. He was born in Flevance, the “White City,” a nation made wealthy by a beautiful but toxic mineral called Amber Lead. The World Government and Flevance’s royalty knew of its poisonous effects for generations but concealed the truth for profit, leading to the entire population slowly dying of Amber Lead Syndrome.

When the world mistakenly believed the disease was contagious, Flevance was quarantined and then systematically annihilated. A young Law witnessed his parents murdered, his friends killed, and his beloved sister Lami burn to death in a hospital fire. He escaped only by hiding under a pile of corpses, emerging as a dying child filled with nihilistic rage, wanting only to destroy as much of the world as he could before his own inevitable death. He found his way to the Donquixote Pirates, where he met Donquixote Rosinante, or “Corazon.”

Upon learning Law carried the secret initial “D.”, Corazon betrayed his brother Doflamingo to save the boy. He stole the Op-Op Fruit to cure Law’s disease, and in his final moments, he was gunned down by Doflamingo. As he died, Corazon used his powers to silence Law’s terrified cries, ensuring the boy’s escape, and died with a massive smile on his face so that Law’s final memory of him would be one of joy. This act of selfless love cured Law not just of his disease, but of his hatred, making this one of the most poignant and painful One Piece saddest moments.

1. Bartholomew Kuma

At the pinnacle of sorrow sits Bartholomew Kuma, whose life was one of unending, selfless suffering from the moment of his birth to his “death” as a mindless cyborg. His story is the most profoundly tragic backstory in One Piece because he never had a moment of true freedom or happiness that wasn’t immediately ripped away and followed by immense pain. Born into the near-extinct Buccaneer race, Kuma and his family were enslaved by the Celestial Dragons. As a child, he watched his mother die from abuse and his father get shot and killed for trying to cheer him up with the story of the Sun God, Nika.

He was then taken to God Valley to be hunted for sport by the World Nobles in their genocidal game. After escaping, he found a semblance of peace as a priest, using his Paw-Paw Fruit powers to literally absorb the pain of others into his own body. He fell in love with a woman named Ginny, only for her to be kidnapped and forced into marriage by a Celestial Dragon. She eventually died from a fatal disease contracted during her enslavement, but not before giving birth to their daughter, Jewelry Bonney.

To save Bonney from the same incurable illness, Kuma made the ultimate sacrifice: he agreed to become a mindless weapon for the World Government in exchange for Dr. Vegapunk curing his daughter. He willingly gave up his body, his memories, and his very consciousness, all to give his daughter a future he could never be a part of.

His greatest acts of heroism, like saving the Straw Hats, were done in the shadows, while the world knew him only as “The Tyrant.” His reward for a lifetime of saintly sacrifice was not peace or glory, but the complete and total erasure of his self, making his life the ultimate tragedy and his tale one of the most devastating One Piece saddest moments.
