Baby 5 - One Piece

Reading Time: 15 mins

Let's take a walk down the memory lane of "One Piece", an anime that has captivated millions with its adventurous narrative, charismatic characters, and grandiose world-building. One of the many characters that add spice to this dynamic storyline is Baby 5.

Making her first appearance in Chapter 682 and Episode 608, Baby 5 is a distinctive character that serves as a vital cog in the Donquixote Pirates. This lass is not just your ordinary pirate lady; she's an assassin and an officer of the notorious Pica Army.


When we talk about the background of Baby 5, it's like peering into a book filled with dramatic and touching stories that have shaped this charismatic character we now see. Born into a life of poverty, Baby 5's early years were marked by hardships that no child should endure. 

It all started in the North Blue, where Baby 5 was born into an extremely poor family. Living conditions were hard, and having a child with such unique abilities made things even tougher. Baby 5 wasn't just an ordinary girl; she was born with the power of the Buki Buki no Mi, a Paramecia-type Devil Fruit. This allowed her to transform any part of her body into a variety of weapons. Rather than being seen as a gift, this peculiar ability was considered a curse, ultimately leading her mother to abandon her at a young age, believing she was cursed. 

This abandonment left a deep wound in Baby 5's heart. The emotional turmoil caused by this event, coupled with her innate desire to be useful to others, shaped Baby 5's character into what it was during her time with the Donquixote Pirates. She could never say no to anyone's request, as she was desperate not to be abandoned again.

The turning point came when Baby 5 joined the Donquixote Pirates. Her life was no longer about mere survival but about taking advantage of her skills to serve as an assassin for the crew. The pirates recognized her value, and in this ruthless crew, Baby 5 found a place where she felt needed. Her desperate need to be useful was frequently exploited, particularly by the crew's leader, Donquixote Doflamingo.


Remember the moment you laid your eyes on her? That slender figure, tall stature, and those captivating, half-closed eyes with long, sweeping lashes. Her long, wavy black hair, often adorned with a bandanna, gives her a pirate-y yet feminine appeal.

One of the most unique aspects of Baby 5's appearance is her choice of attire. Aiming to mirror her weapons lady persona, she dons a series of flamboyant and quite imaginative outfits throughout the series. Whether it's a maid outfit, a dress resembling ammunition, or even a cowgirl-style look, each of her styles enhances her eccentric character and adapts to the variety of weapons she can turn into.

But it's not just her outfits that demand attention. Her body, too, undergoes significant changes when she transforms into different weapons, thanks to her Buki Buki no Mi Devil Fruit powers. For instance, when she transforms into a sword, her legs become the blade while her upper body forms the handle. Interestingly, Baby 5's appearance also bears signs of her emotional state and personality. The ever-present cigarette in her mouth denotes her rebellious streak.


The Buki Buki no Mi, a Paramecia-type Devil Fruit, is what sets Baby 5 apart from many characters in the series. With it, she can transform parts of her body or her entire being into various types of weapons, an ability that drastically amplifies her combat capabilities. This Devil Fruit has enabled her to generate a vast arsenal of armaments, from simple bladed weapons to more complex ones like firearms and explosives. 

But it's not just about creating weapons. The fruit's power extends to allowing Baby 5 to control the weapons she becomes. For instance, when she transforms into a gun, she can also fire bullets. It's a remarkable ability that makes her one of the most versatile and unpredictable fighters within the Donquixote Pirates.

Of course, like all Devil Fruit users, Baby 5 has to pay a price for her abilities. The sea, which is a significant component of the One Piece world, becomes her nemesis. She loses her ability to swim and becomes weakened when submerged in water, a common vulnerability among Devil Fruit users.

Baby 5's ability to morph her body into various weapons is not just remarkable, it's nothing short of extraordinary. It's difficult not to be in awe when she transforms her arm into a giant spiked club or a big blade. The sheer force that she can generate with her melee weapons can send shockwaves through an adversary's body, not something many could walk away from. You get hit with that, you stay hit.

But Baby 5 doesn't limit herself to close-combat weapons. She's equally at home with ranged weapons. Remember that time she transformed her leg into a missile and blasted it at an enemy? Yeah, she's got a leg up on the competition with that one (pun intended). 

And then there's her ability to morph into firearms. Machine guns, pistols, you name it, she can form it. The rapid-fire ability that she possesses when in her firearm forms is simply terrifying. When those bullets start raining, you better find some serious cover. Baby 5 can even transform her body into explosives. It's a high-risk move that speaks volumes about her dedication to a fight. Not many can boast about being their own cannonball. 

Strong and agile, Baby 5 exhibits physical strength that can go toe-to-toe with the best of fighters in the One Piece world. Known for her dexterity and agility, she can swiftly adapt her body movements in various high-stakes situations, an attribute that has proved vital in her confrontations. From navigating tumultuous sea battles to engaging in close-quarter combat on land, her ability to adapt and respond to physical challenges is a testament to her training and natural aptitude.

Moreover, her endurance is worth mentioning. Baby 5 can withstand severe injuries and continue fighting, showing off her extraordinary resilience. Like many characters in the One Piece series, her ability to push past her limits, even when physically taxed, is nothing short of remarkable. Let's not forget her speed, which gives her an edge during combat. Baby 5's quick reflexes and ability to move at high speeds enable her to dodge attacks efficiently and retaliate swiftly, making her a formidable opponent.


Here, let's take a closer look at what defines Baby 5's personality, and what makes her such a standout character. A key feature of Baby 5's personality is her deep-rooted desire to be needed. This can be traced back to her traumatic childhood, where she was abandoned by her mother because she was considered a burden. This led Baby 5 to develop a compulsion to be useful to others to the point of self-destruction. She is unable to refuse any request made of her, even if it puts her own life at risk, which often leads to her being manipulated by others.

Interestingly, her name "Baby 5" symbolizes this aspect of her personality. She was the fifth 'baby' to be taken in by the Donquixote Pirates and she considers herself as a tool or a 'baby' to be used by others. This fixation on being useful shows how her past has shaped her personality, providing a clear example of how character backgrounds can influence their behavior and character traits in "One Piece."

Another aspect of Baby 5's personality is her rapid emotional shifts. She is known for her unpredictable mood changes, which can swing from cheerful to murderous in the blink of an eye. This, along with her tendency to jump to conclusions and act on impulse, makes her one of the most unpredictable characters in the series. Despite her volatile nature, she is capable of deep affection and loyalty, especially towards those she considers as family.


Baby 5's relationships within the world of "One Piece" are as colorful and complex as her character. From her ties with the Donquixote Pirates to her romantic involvement with Sai, these relationships significantly shape her storyline and influence her character development.

Baby 5's bond with the Donquixote Pirates, particularly Donquixote Doflamingo, is a central aspect of her character. Despite his manipulative ways, Baby 5 views Doflamingo as a sort of father figure, perhaps due to the void left by her own parents. She is fiercely loyal to the pirate crew, and her need to feel useful is often exploited by Doflamingo and the others. This dependence is, however, a double-edged sword. While it provides Baby 5 with a sense of belonging, it also leads to her being manipulated and taken advantage of.

One of the more intriguing relationships Baby 5 forms in the series is with Sai, the leader of the Happo Navy. Initially, their interactions are filled with conflict, but as the story progresses, a deeper bond forms between them. Sai, unlike others, recognizes Baby 5's compulsion to be useful as a problem and earnestly tries to help her overcome it. This sincere concern for her well-being sets Sai apart from others in Baby 5's life. Their relationship takes a romantic turn, culminating in an impromptu marriage proposal from Sai, which Baby 5 accepts. This relationship proves pivotal for Baby 5, providing her with a healthier emotional connection than she had experienced with the Donquixote Pirates.

Baby 5 also has a noteworthy relationship with Law, another member of the Donquixote Pirates. Despite Law's reserved nature, he and Baby 5 share an understanding, likely due to their shared past of loss and hardship. Law's eventual betrayal doesn't seem to cause a rift between them, suggesting a deeper bond.

Key Battles and Moments

If there's one thing we all know about Baby 5, it's that she's no pushover when it comes to a fight. First off, let's not forget her clash with Sai during the Dressrosa arc. She had just been sent to assassinate him, and she wasn't holding back. However, Sai managed to counter her attacks effectively. It was during this intense fight that Sai proposed to Baby 5, completely taking her by surprise. But don't be fooled, this didn't slow her down for a second. She continued her assault, showcasing her skill and tenacity.

Then we have the battle at Punk Hazard, where Baby 5 and Buffalo faced off against Nami, Usopp, and the children they were protecting. Baby 5, despite her seemingly tough exterior, showed a softer side here, unwilling to hurt the children. That's the thing about Baby 5 – underneath all those weapons, she's got a heart.

However, the battle that I think really demonstrates Baby 5's strength was against Franky at Dressrosa. Franky, being a cyborg with incredible power, was no easy opponent. Despite this, Baby 5 held her own against him. This fight was a real testament to Baby 5's abilities and her perseverance in the face of a tough adversary.

But you see, Baby 5's moments of action aren't just about fights. Take, for instance, when she decided to defect from the Donquixote Pirates to join Sai and his crew. That was a battle in its own right – a personal one. She chose to stand up against the manipulative Doflamingo, which required a different kind of strength.

Role in the Donquixote Pirates

A key part of her role was her task as an assassin for the crew. Thanks to her Devil Fruit power – the "Buki Buki no Mi" – Baby 5 could transform parts of her body into all sorts of weapons, from guns to swords to explosives. That’s not something you see every day, right? This made her a formidable opponent and a valuable asset for carrying out the crew's dirty work. It's safe to say that she had a few notches on her belt.

Beyond just her fighting abilities, though, Baby 5's personality also had a big impact on her role within the crew. Because of her inability to refuse a request – no matter how absurd – she often found herself exploited by her crewmates. This made her somewhat of an underdog within the crew, and in my book, it adds another layer of depth to her character.

However, despite her importance to the crew, Baby 5's loyalty to the Donquixote Pirates wasn't unwavering. In a twist of events, she defected from the crew after falling in love with the leader of the Happo Navy, Sai, during the Dressrosa arc. Talk about a soap opera! This decision was a testament to her desire to escape the manipulation she had faced within the crew and seek a happier life.
