One Piece: 8 Characters With The Darkest Backstories

This article contains spoilers for One Piece.

Beyond its exciting adventures, One Piece is famous for its characters and their often heartbreaking pasts. Creator Eiichiro Oda doesn’t shy away from showing his characters endure immense hardship before allowing them to find peace, happiness, and purpose. This approach also allows the series to reflect real-world struggles.

One Piece doesn’t shy away from showing hardship, and anyone can experience it – even the heroes, their friends, or Luffy himself. Characters face incredibly difficult pasts, including abuse, being taken advantage of, and devastating losses. Let’s explore some of these characters and the painful stories that shaped them.

Boa Hancock

The Celestial Dragons Abused Boa Hancock And Her Sisters

The Celestial Dragons are among the most villainous characters in One Piece, known for their selfishness and disregard for others. They’ve inflicted immense suffering on many, including Boa Hancock and her sisters, who were victims of their cruelty.

Before becoming the strong woman she is now, Hancock was enslaved and lost her innocence through horrific abuse at the hands of the Celestial Dragons. The full extent of this suffering is hinted at, but much is left to the reader’s imagination.

Big Mom

No One Accepted Linlin For Real

Charlotte Linlin, better known as Big Mom, has a deeply disturbing past, considered one of the most tragic in One Piece. Even as a child, her insatiable hunger and quick temper made her a threat to others. Her own parents couldn’t cope with her behavior and abandoned her, viewing her as an unbearable weight.

Mother Carmel, who cared for Big Mom, was secretly planning to betray her by selling her to the Marines. Despite this, Big Mom began to trust Carmel, and even after Carmel died, she continued to believe Carmel was a good and kind person, never realizing her true intentions or how she actually died.

Trafalgar Law

Law Pretended to Be Dead to Survive

Trafalgar Law can seem mysterious unless you know about his tragic past. He grew up in a peaceful and beautiful town called Flevance, which was devastated by a terrible act of cruelty. When he was just ten years old, Law lost his home, his family, and all his friends, fueling a lifelong quest for revenge.

Law experienced unimaginable trauma as a child, witnessing his parents’ murder and helplessly watching his sister perish in a fire. He barely survived, forced to hide among corpses and fight for his life in the aftermath.

Sanji

The Vinsmoke Family Faked His Death

Sanji was born into the Vinsmoke family, the royalty of the Germa Kingdom, and was expected to become a powerful and influential prince. However, his father and brothers mistreated him because he didn’t meet their standards. They believed his compassion and empathy damaged the family’s reputation.

Sanji enjoyed a fulfilling life with Luffy and the Straw Hat Pirates, but his path to get there was difficult. He and Zeff once faced extreme hardship, struggling to find food and barely surviving on a remote island. On top of that, Sanji discovered the painful truth about Zeff’s past and the great sacrifice he made to ensure Sanji’s survival.

Brook

Brook Was Alone For Decades

Episode 380 of One Piece is a particularly heartbreaking and unsettling installment for viewers, largely due to the story of Brook’s past. The Straw Hat Pirates’ musician suffered immense loss and spent decades enduring loneliness after losing his entire former crew, the Rumbar Pirates, and even his physical body.

I watched as all that remained of Brook was his physical form, a shell haunted by a spirit adrift at sea. Eventually, he found a home with Luffy and his crew, but he carried a heavy burden. He’d lost his shadow, leaving him unable to bear the sunlight, and even more painfully, he hadn’t been able to keep his promise to Laboon. The guilt of letting down such a close friend clearly weighed on him.

Nico Robin

Robin Lost Everything

Nico Robin has a deeply tragic past, and her early life was filled with hardship that often moves fans to tears. She experienced pain no child should have to endure, but she overcame it all and became incredibly resilient.

Robin fondly remembers her time in Ohara, where she loved learning and exploring through books. However, her childhood wasn’t easy. After her mother disappeared, she faced constant mistreatment – her relatives were cruel, and other children bullied her relentlessly.

Robin had a difficult childhood, becoming an orphan when the World Government destroyed her home, Ohara. She spent years evading capture until she finally found acceptance and a family with Luffy and the Straw Hat Pirates.

Kuma

Kuma Sacrificed Everything

It absolutely breaks my heart to think about Kuma’s early life in One Piece. He went through things no one, especially a child, should ever experience. Slavery and genocide were just… normal for him. Being a Buccaneer meant constant abuse from the World Nobles, and he lost his parents in the most horrific way imaginable – just for someone else’s amusement. It completely shattered his sense of safety and left him feeling utterly lost and alone. It’s a truly devastating backstory, and it explains so much about the man he becomes.

To make matters even more heartbreaking, Kuma also sacrificed his own chance at love and happiness with Ginny. Haunted by his mother’s painful past, he believed that a relationship with Ginny would ultimately lead to her suffering as well. Though he deserved a happy life with her, his own trauma prevented him from pursuing it. Sadly, even with all his selflessness, Kuma found no peace or relief from his pain.

Loki

Loki’s Mother Tried to Kill Him

Loki, the unwanted prince of Elbaf, had a difficult childhood filled with loneliness. He never felt loved or accepted, and his mother was frightened by his unusual appearance – particularly his striking eyes and horns – leading to rejection instead of affection.

It felt like things couldn’t get any harder for Loki, but then he lost Ida. She was the first person who’d ever really shown him genuine love and care, and her absence left a hole in his life that nothing could fix. To make matters even worse, the terrible prophecy about him killing his father actually came to pass.
