In a world full of captains, admirals, and kings, One Piece may seem to new fans to be dominated by lone individuals with lots of power. That couldn't be further from the truth. In a lonely life on the Grand Line's shaky seas, the most sturdy thing that one can hold onto is a strong bond. Whether it's a reliable crewmate or a best friend, One Piece is defined by its relationships.

And there's rarely a relationship stronger than family. One Piece is chock full of strong families carrying on ideals and love far stronger than a regular pirate crew or army. Not all of them are defined so clearly by biology but all of them share a similar sense of togetherness. This list will be looking at some of the strongest bonds, as it ranks some of the strongest families in One Piece.

10 The Riku Family

Dressrosa is the land of gladiators and passionate women willing to stab people and its leading family more than portrays that romanticism and strength. The Rikus are the royal family that took over the country when the Don Quixote family left to live in Mariejois.

The modern bloodline consists of King Riku Doldo III, a fighting king that fought in the battle royal for the Flame Flame Fruit, Viola, an ex-agent of the Don Quixote family with a powerful Devil Fruit and an even deadlier knife, Rebecca, a princess practically raised by the sword, and Kyros, the mightiest gladiator that the Corrida Colosseum had ever seen.

9 The Gorgon Sisters

Few women on Amazon Lily get any stronger than Boa Hancock and her Gorgon Sisters. After the poor girls were kidnapped during one of their first voyages as Kuja Pirates, they'd be subjected to years of trauma at the hands of the Celestial Dragons. Using those experiences and the Devil Fruits that they were forced to eat, the Gorgon Sisters made strong efforts to rise up in the Kuja and eventually lead them to become part of the Seven Warlords of the Sea.

Sandersonia and Marigold are two powerful warriors who use different Snake Snake Fruits to powerful degrees. Boa Hancock is the strongest of them all, dominating with powerful martial arts, Haki, and her Love Love Fruit.

8 The Neptune Family

By virtue of being fishmen and merfolk, the Neptune Family already gets a lot of points on this list. Its patriarch is the ruler of the Ryugu Kingdom and a mighty fishman capable of manipulating the waters of the sea. His sons are the leading knights of the country who the townspeople respect and the criminals fear.

Though Neptune's wife may be long gone, her loving spirit is still within their daughter, Shirahoshi, who turns out to be the Ancient Weapon, Poseidon. With what seems to be an advanced version of the Voice of All Things, the youngest Neptune is able to command the world's Sea Kings with just her voice. Having to keep her from crying as a baby must have been a nightmare.

7 The Chinjao Family

The Chinjao Family is one of the world's most dangerous families, as they lead one of its top pirate groups, the Happo Navy and are masters of the mysterious martial art, Hasshoken which utilizes strong vibrations to break through nearly any defense. Its twelfth and last leader was Don Chinjao, a hulking man who was once used his pin-shaped head to split an entire, ice continent.

The Happo Navy is now in the control of his grandchildren, Boo, a powerful warrior within his own right, and Don Sai, a clear master of Hasshoken who now leads the Happo Navy. Don Sai was recently married to Baby 5, one of Doflamingo's top assassins, making this family a little more dangerous.

6 Roger's Family

Gol D. Roger's family loses some points given that there currently doesn't appear to be a very long bloodline. However, what's there has left quite an impression on the fans and the world. Gol D. Roger himself was an adventurer strong and hearty enough to travel the entire world and claim some of its greatest treasures, eventually taking on the title "King of the Pirates."

His wife was Portgas D. Rouge. There is not a lot that's known about her; but when the World Government began to hunt down Roger's heir, Rouge was able to suppress her birthing for twenty months using sheer willpower. Even though the toll that it took would eventually take her life, the child that she brought into the world, Portgas D. Ace, proved to be a frightening force whose very life changed the entire world.

5 The Don Quixote Family

The Don Quixote Family will be the first family on this list to be a non-traditional family. To be fair, Donquixote Doflamingo is related to the Don Quixote Family that once ruled Dressrosa and rose to prominence as a Celestial Dragon. However, after a tumultuous childhood, he'd abandon that life to form a stronger, deadlier family of his own.

The Don Quixote Family is one of the strongest pirate crews in all of One Piece. They'd play off both the World Government and the Emperors and broker the arms deals and perhaps even the wars between different countries. Its very family members are some of the most dangerous opponents that the Straw Hats have ever seen, and Doflamingo, despite his easygoing attitude, was certainly no slouch.

4 The Vinsmoke Family

While there are plenty of dangerous pirate crews and rival governments to the World Government, one may be hard-pressed to find one with as famous, defacing propaganda as the Germa Kingdom. Its royal family, the Vinsmokes, are the leading villain of an ongoing comic strip within the One Piece world that's meant to teach children to be good.

The Vinsmokes, however, are much worse villains than their comic strip lets on. Rather than just be cartoonish villains of the week, the Vinsmokes and their Germa 66 are a highly evolved and scientifically advanced group that uses a variety of inventions to amplify their already mighty strength. Given that Sanji was once considered their weakest and is one of the strongest characters in the entire series, there may be something to this family. Not love but something.

3 The Charlotte Family

The Big Mom Pirates assemble to attack Luffy in One Piece.

The Charlotte Family is easily one of the biggest families in all of One Piece. Big Mom has carefully chosen powerful men across different species to curate a diverse family of different skills, bodies, and power sets. In total, she has 85 children, with some of the youngest already willing to stab a person.

If her children are not controlling different sects of Totland, they're working as some of Big Mom's top guard, such as her legendary Sweet Commanders. Looking at that strength, one has to wonder if Big Mom is making a family or an army, though it's probably both.

2 The Whitebeard Pirates

When Edward Newgate was part of the Rocks Pirates, he didn't dream of having treasure or glory. All he wanted was a family. So, when he set out to start a crew of his own, he took in some of the various scoundrels of the world who were too rowdy to be regular citizens and made them his adoptive children.

The Whitebeard Pirates are renowned for being both one of the strongest pirate crews in the world, as well as one of the closest ones to abide by a single banner. When one of them gets hurt, they all take it personally.

1 The Monkey Family

Garp and Luffy in One Piece.

The Monkey Family may not be the closest family out there. Monkey D. Luffy was genuinely surprised that he had a dad at all. However, what they lack in remembering either's birthdays, they more than make up for in sheer power and influence.

Monkey D. Garp is the most famous Marine of them all who spent years personally hunting down Gol D. Roger. Dragon is the leader of the Revolutionary Army and the most wanted man in the world. For those reading this list, Luffy needs no introduction. If Luffy ever has a kid, there may not be anything left of the world.
