Blackbeard’s Third Devil Fruit Can Reshape the World
Blackbeard’s third Devil Fruit has been one of the biggest ongoing discussions in the One Piece fandom.
For years, fans have debated how Marshall D. Teach can use more than one Devil Fruit. He already controls the Dark-Dark Fruit, one of the strangest powers in the series. He also stole Whitebeard’s Tremor-Tremor Fruit, giving him the power to shake the world.
But that may only be the beginning.
If Blackbeard can use more than one Devil Fruit, then fans should be asking two major questions.
Can Teach gain a third Devil Fruit?
And if he can, what power would actually complete him?
That second question matters just as much as the first.
Blackbeard does not collect powers randomly. The Dark-Dark Fruit gives him control. The Tremor-Tremor Fruit gives him destruction. So if he gains another ability, it should not feel like another strong Devil Fruit stacked on top.
It should feel like the final piece of a larger system.
A power that works with darkness and earthquakes.
A power that helps him destroy, dominate, and reshape the world after he breaks it.
So before we can talk about what Blackbeard’s third Devil Fruit could be, we have to start with the real mystery.
How can Blackbeard use more than one Devil Fruit in the first place?
The Mystery Behind Blackbeard’s Third Devil Fruit
Blackbeard has always been different.
That is not just speculation. One Piece has gone out of its way to make Teach feel like an anomaly.
In the world of One Piece, eating more than one Devil Fruit should be impossible. The series treats this as a hard rule. A person who tries to gain a second Devil Fruit power is expected to die.
Yet Blackbeard broke that rule in front of the entire world.
At Marineford, he stole Whitebeard’s Tremor-Tremor Fruit and walked away with two powers. No explosion. No death. No clear explanation.
That moment changed everything.
Before Marineford, Blackbeard was already dangerous because of the Dark-Dark Fruit. After Marineford, he became something else entirely: the only known person in the story capable of wielding two Devil Fruits at the same time.
That feat propelled him into infamy, turning him from a Warlord of the Sea into one of the most feared pirates in the world.
A Yonko.
But Oda did not present this as a random miracle.
He planted clues much earlier.
Blackbeard’s Body Is the First Clue
One of the biggest hints comes from Marco during the Marineford War.
After Blackbeard takes Whitebeard’s power, Marco explains why this should be impossible for a normal human, stating:
“It would be impossible for another human. But you should all know that Teach is different!!! The very structure of his body is strange.” — Chapter 577
That line matters.
Marco was not guessing like an average pirate. He was Whitebeard’s first division commander, a veteran fighter, and someone who knew Teach personally from their time on the same crew. When Marco says Blackbeard’s body is unusual, the story is telling us to pay attention.
This strange body may be the reason Blackbeard can hold more than one Devil Fruit.
But Marineford was not the first time Oda hinted at this.
Back in Mock Town, after Blackbeard gives his famous speech about dreams never dying, Nami wonders who this strange man is. Luffy and Zoro correct her:
“Dunno… but it’s not him… it’s ‘them’…” — Chapter 225
That moment has haunted the fanbase for years because it feels too intentional to ignore. Luffy and Zoro sensed something unusual about Teach before the story ever revealed his full danger.
When we combine that moment with Marco’s comment at Marineford, a pattern starts to form.
Blackbeard may not function like a normal person.
If his body, soul, lineage, or hidden ability allows him to carry multiple powers, then Blackbeard’s third Devil Fruit is not just possible.
It may have been part of the plan from the beginning.
Why Two Devil Fruits May Not Be Enough
Blackbeard already has two of the most dangerous Devil Fruits in One Piece.
The Dark-Dark Fruit lets him pull things into darkness, crush his surroundings, and nullify other Devil Fruit abilities through direct contact. Even among Logia-type powers, the Yami Yami no Mi stands out because it does not behave like a normal Logia.
Most Logia users can turn into their element and avoid physical attacks.
Blackbeard cannot.
Instead, he takes even more pain than a normal person. That weakness makes the Dark-Dark Fruit powerful but risky. It gives Teach one of the most dangerous abilities in the world, but it also leaves a major vulnerability.
Then he gains the Tremor-Tremor Fruit.
The Gura Gura no Mi allows Blackbeard to create tremendous earthquakes, crack the air, and destroy islands. Whitebeard used this power to terrify the Marines and shake Marineford itself. In the wrong hands, it is not just a combat ability.
It is a natural disaster.
So Blackbeard now has one power built around control and another built around destruction.
Yet something is still missing.
That is where the real search for Blackbeard’s third Devil Fruit begins.
Because the next power should not just make him stronger.
It should complete what darkness and earthquakes have already started.
The Devil Fruit That Completes Blackbeard
If Blackbeard’s third Devil Fruit exists, it cannot just be powerful.
It has to fit.
Darkness gives Teach control. Earthquakes bring destruction. Together, those powers make Blackbeard a walking disaster.
But they still leave one major question.
After Blackbeard breaks the world, what power lets him reshape it?
That is where one Devil Fruit starts to stand above the rest.
Akainu’s Devil Fruit.
The Magma-Magma Fruit.
The Magma-Magma Fruit gives Sakazuki the power to create, control, and become magma. It is one of the most destructive Devil Fruits in the entire series, and Oda has made Akainu’s power feel like a symbol of absolute violence.
Oda even emphasized how dangerous Akainu would be as a pirate, stating that if Sakazuki were the protagonist, he would be so powerful that One Piece could end within a year.
That statement frames Akainu as more than a strong Marine. His power is so overwhelming that, in the wrong hands, it could completely accelerate the race for the One Piece.
That matters because Blackbeard’s current powers already represent domination and destruction.
Magma would give him something even more terrifying: the power to burn, bury, and reshape the land.
That is why Blackbeard’s third Devil Fruit being the Magma-Magma Fruit makes so much sense.
It does not just add another ability to his arsenal.
It completes a destructive system.
That trio would make Teach more than a pirate.
It would make him a walking apocalypse.
Blackbeard’s Third Devil Fruit Is About More Than Power
The strongest part of this theory is that Blackbeard does not chase power randomly.
He moves like a strategist.
He waited years before betraying Whitebeard. He joined the Seven Warlords when it benefited him. He invaded Impel Down at the perfect time. Then he stole Whitebeard’s Devil Fruit when the world was distracted.
Later, after the Warlord system collapsed, he immediately targeted Boa Hancock’s Love-Love Fruit.
That tells us something important.
Blackbeard is not just collecting powerful Devil Fruits because they are strong.
He is collecting powers that serve a larger plan.
The Dark-Dark Fruit helped him start that plan.
But Blackbeard’s third Devil Fruit may be the power that lets him finish the job.
If his goal is connected to Rocks D. Xebec, the Holy Land, and the dream of turning the world upside down, then Akainu’s Devil Fruit becomes much more than a weapon.
It becomes the tool Blackbeard needs to reshape the world after he breaks it.
Blackbeard’s Pattern of Stealing Devil Fruits
To understand why Akainu’s Devil Fruit matters, we have to look at Blackbeard’s pattern.
Teach does not just chase status.
He chases useful power.
That is exactly what we saw after the Marineford War. Once Blackbeard gained Whitebeard’s Tremor-Tremor Fruit, he did not stop building his crew. Instead, his pirates became known for hunting powerful Devil Fruit users.
That detail is important because it shows Blackbeard’s rise is not only about territory, treasure, or reputation.
It is about collecting abilities that serve his endgame.
So if Blackbeard’s third Devil Fruit becomes part of the story, it should follow the same pattern.
It should not be random.
It should be useful.
And most importantly, it should give Teach something his current powers do not fully provide.
That brings us to one of the biggest clues in the story.
Blackbeard Targeted Boa Hancock’s Devil Fruit
After the Seven Warlords system was abolished, the former Warlords lost their government protection.
That created chaos.
The Marines moved against them, but Blackbeard saw the same situation as an opportunity. He made that clear when he told his crew:
“Pack yer bags!! On to the ship!! Why let the Marines reap the reward… when I stand to gain from this?!!” — Chapter 956
That line tells us everything.
Blackbeard was not reacting emotionally. He was calculating. The Marines were moving to capture the former Warlords, and Teach immediately recognized that valuable Devil Fruits could be taken in the chaos.
Instead of waiting, he went straight to Amazon Lily and tried to take Boa Hancock’s Devil Fruit.
That alone tells us a lot about Teach.
He was not just looking for any power. Hancock’s Love-Love Fruit is dangerous because it can wipe out entire groups of enemies under the right conditions. It can turn people to stone, neutralize armies, and completely shift the outcome of a battle.
Blackbeard understood that value immediately.
However, he failed to take it.
And that failure matters.
After Hancock, Blackbeard also crossed paths with Trafalgar Law, another former Warlord with one of the most valuable Devil Fruits in the series.
The Op-Op Fruit is not just strong in battle. It has medical, spatial, and possibly immortality-related importance. Once again, Blackbeard was not chasing a random ability.
He was going after a Devil Fruit with massive strategic value.
That pattern points us toward a bigger idea.
If Teach could not secure Hancock or Law’s power, then his next major target may be something even more destructive.
Something that does not just help him win fights.
Something that helps him dominate the world after he wins.
Why Akainu Starts to Stand Out
This is where Akainu becomes important.
Sakazuki is not just another powerful Marine. He is the Fleet Admiral. He represents the military force of the World Government, and his Devil Fruit is one of the most devastating powers in One Piece.
The Magma-Magma Fruit is not subtle.
It burns through enemies, overwhelms battlefields, and leaves permanent scars on the world around it. Akainu used that power at Marineford to become one of the most terrifying figures in the entire war.
That matters for Blackbeard because Teach’s current powers already lean toward large-scale destruction.
The Dark-Dark Fruit helps him control the battlefield.
The Tremor-Tremor Fruit lets him shatter it.
Akainu’s Devil Fruit, however, would let him change the battlefield itself.
That is a major difference.
Magma does not just destroy and disappear. It burns, spreads, hardens, and leaves behind a changed environment. So if Blackbeard’s third Devil Fruit is meant to complete his existing powers, the Magma-Magma Fruit fits that role better than almost anything else.
It gives him a power that can match the scale of his ambition.
And Oda may have hinted at this possibility much earlier than people realize.
The Bonney Scene May Have Foreshadowed Akainu
One of the most interesting moments happens after the Marineford War, when Blackbeard captures Jewelry Bonney.
At first, Teach tries to use Bonney as a bargaining chip. He wants to trade her to the Marines in exchange for a battleship.
But then Akainu arrives.
The moment Blackbeard realizes Sakazuki is coming, he backs off and says:
“Dammit! I’m not looking to get into that kinda stuff just yet.”
Blackbeard does not say Akainu is impossible to defeat. He does not say he will never challenge him. Instead, he says he is not looking to get into that “just yet.”
That phrase leaves the door open.
At that moment, Teach had only recently gained the Tremor-Tremor Fruit. He may not have fully mastered it yet. His crew was still growing, and his position in the world was not fully secure.
So Blackbeard’s retreat does not make him weak.
It makes him patient.
He may not have been ready to confront Akainu then.
But that does not mean he would never target him.
Blackbeard May Be Waiting for the Right Moment
Blackbeard rarely makes his biggest moves too early.
Teach lets the world create the opening. Then he steps in and takes what he wants.
So when he ran from Akainu, that moment may not have closed the door on a future clash.
It may have opened it.
At that point, Blackbeard had only recently gained the Tremor-Tremor Fruit. He may not have fully mastered it yet. His crew was still growing, and his position in the world was not fully secure.
But now things are different.
Blackbeard is a Yonko.
His crew has gained stronger Devil Fruit powers.
He has captured major military value before, including Garp.
He has shown interest in bargaining with the World Government.
And the world itself is becoming more unstable.
That is exactly the kind of situation where Teach thrives.
If Akainu ever becomes isolated, distracted, weakened, or forced into a major crisis, Blackbeard would have every reason to move.
Not because he wants revenge.
Not because he wants a fair fight.
Because Sakazuki’s Devil Fruit may be the missing piece Blackbeard needs.
Why the Magma-Magma Fruit Fits Blackbeard’s Endgame
The Magma-Magma Fruit fits Blackbeard because it matches the scale of his ambition.
Teach is not just trying to become another Emperor. He has already reached that level. He is not just trying to become famous. The whole world already knows his name.
Blackbeard wants something bigger.
Chapter 1107 makes that clear when Catarina Devon and Van Augur confront Saint Jaygarcia Saturn on Egghead.
Saturn questions why dangerous criminals from Impel Down’s Level 6 would submit to Blackbeard’s command.
Catarina Devon responds:
“Oh, but Teach is different.”
Saturn then adds:
“As is his bloodline…”
After that, Saturn asks what the Blackbeard Pirates are really after.
Van Augur answers with one chilling line:
“The world.” — Chapter 1107
That exchange confirms Blackbeard’s ambition is not limited to treasure, status, or even becoming Pirate King.
Teach is aiming for the world itself.
That is why Blackbeard’s third Devil Fruit has to be judged differently. If his goal is global domination, then his final power should match that scale.
That is why Akainu’s Devil Fruit feels different from Hancock’s or Law’s.
Those fruits are powerful.
But Sakazuki’s power fits the image of Blackbeard as a final disaster.
If Teach truly wants to turn the world upside down, then magma is not just another weapon.
It is the power that makes that dream physically possible.
Vegapunk’s Warning Makes This Theory More Terrifying
This is where Blackbeard’s third Devil Fruit becomes much bigger than a simple power upgrade.
Because One Piece is no longer just about pirate crews fighting over treasure.
The world itself is changing.
Vegapunk’s message made that clear. After the destruction of Lulusia, the world experienced earthquakes, and sea levels rose by one meter. Vegapunk later revealed that the Ancient Weapon used on Lulusia caused that rise and warned that the world is sinking.
— Chapters 1089 and 1115
The world of One Piece is not stable.
The ocean is becoming a bigger threat. Islands can disappear. Kingdoms can fall. People can lose everything without ever understanding why.
Blackbeard thrives in unstable worlds.
When systems break, Teach moves.
He rose during the chaos of Whitebeard’s decline. He used the Warlord system to reach Impel Down. He stole Whitebeard’s power during the confusion of Marineford. Then he targeted former Warlords once the World Government stripped away their protection.
So if rising seas create a global crisis, Blackbeard would not just react to it.
He would exploit it.
And that is where the Magma-Magma Fruit becomes terrifying.
The Magma-Magma Fruit Could Reshape the World
If Teach gains the Magma-Magma Fruit, he would not just become more dangerous in battle.
He could gain the power to reshape the world itself.
In a world where land is disappearing, the power to create, expand, or control land becomes more than a combat ability.
It becomes far more than political or military power.
It becomes survival itself.
That is why Akainu’s Devil Fruit could be so important.
The Tremor-Tremor Fruit can crack the world apart.
The Dark-Dark Fruit can pull enemies into Blackbeard’s control.
But the Magma-Magma Fruit could give Teach something neither of those powers fully offers.
A way to create new land from destruction.
A way to turn disaster into territory.
A way to make people depend on him after the world falls apart.
And when you look at Blackbeard’s base, that possibility becomes even more terrifying.
Hachinosu Could Become Blackbeard’s Sanctuary
Blackbeard’s main base is Hachinosu, also known as Pirate Island.
At first glance, Hachinosu looks like a lawless pirate stronghold. It is chaotic, violent, and filled with criminals. But if the world keeps heading toward disaster, Hachinosu could become something much bigger.
It could become Blackbeard’s kingdom.
That is where the Magma-Magma Fruit fits perfectly.
If Blackbeard can use magma to create volcanic land, expand existing territory, or reshape the area around Pirate Island, he could turn Hachinosu into one of the most valuable places in the world.
Imagine the world drowning island by island. Kingdoms panic. Civilians flee. Pirates fight over territory. The Marines lose control. The World Government struggles to protect the Celestial Dragons while the rest of the world falls apart.
Then there is Blackbeard, sitting on a growing island.
A dark kingdom built from magma, fear, and desperation.
Blackbeard would not need to force everyone to serve him at first.
Survival would do that for him.
Blackbeard Could Weaponize Desperation
This is what makes the theory so dangerous.
Blackbeard does not need to save the world to rule it.
He only needs to control the place people run to when everything else collapses.
That fits Teach perfectly.
He is not a hero. He is not trying to protect innocent people out of kindness. But if he can offer shelter, and protection in a world where those things are disappearing, people may have no choice but to gather under his flag.
That is how Hachinosu could evolve from Pirate Island into something far worse.
A sanctuary with a price.
Blackbeard could offer survival while quietly turning desperate people into soldiers, workers, informants, and loyal subjects. They may not believe in him. They may not even like him.
But if the alternative is a lack of safety and security, many people would submit anyway.
That is the terrifying logic behind Blackbeard’s third Devil Fruit.
The Magma-Magma Fruit would not just help him kill stronger enemies.
It could help him build a kingdom from the ruins of the old world.
And when you combine that with the Tremor-Tremor Fruit, the danger becomes even worse.
Earthquakes Break the World, Magma Rebuilds It
The Tremor-Tremor Fruit and Magma-Magma Fruit would create a horrifying combination.
One power breaks the world apart.
The other power reshapes what is left behind.
With the Tremor-Tremor Fruit, Blackbeard could trigger massive destruction, split islands, damage coastlines, and accelerate the chaos already spreading across the world. Whitebeard’s power was already feared because it could destroy the world.
In Blackbeard’s hands, that fear becomes even darker.
Teach is not the kind of person who uses destruction as a last resort.
He uses it as an opening move.
Then, with the Magma-Magma Fruit, he could exploit the damage. He could burn through enemies, alter terrain, harden molten rock, and create brutal new environments that only his forces can control.
That is why this combination feels so dangerous.
Blackbeard would not simply destroy for the sake of destruction.
He could destroy old systems, then build his own kingdom on top of the wreckage.
That is the real reason Blackbeard’s third Devil Fruit may be the Magma-Magma Fruit.
It does not just make him stronger.
It gives his destruction a purpose.
Blackbeard’s Kingdom Could Rival the World Government
This would also explain why Blackbeard’s goal being “the world” matters so much.
If Teach only wanted treasure, he would not need this kind of power.
If he only wanted the title of Pirate King, the Dark-Dark Fruit and Tremor-Tremor Fruit might already be enough.
But if he wants to challenge the World Government itself, then he needs more than strength.
He needs a place that can stand against the old world while everything around it collapses.
That is what Hachinosu could become.
A rival kingdom.
A pirate empire.
A twisted answer to the World Government.
With Blackbeard’s third Devil Fruit, that empire could be built through disaster.
The World Government rules through history, secrecy, military force, and fear.
Blackbeard could rule through chaos, survival, and the promise of land in a drowning world.
That is why the Magma-Magma Fruit fits his endgame so well.
It gives him the power to turn destruction into opportunity.
And no character in One Piece understands opportunity better than Marshall D. Teach.
Why This Makes Akainu the Perfect Target
This is also why Akainu is not just a random candidate.
Sakazuki stands at the top of the Marines. He represents absolute justice, military authority, and the violent arm of the World Government.
So if Blackbeard takes Akainu’s Devil Fruit, it would be symbolic and practical at the same time.
Practically, Teach gains one of the most destructive Logia powers in the story.
Symbolically, he steals the burning fist of the Marines and turns it against the very world Sakazuki tried to protect.
That would be pure Blackbeard.
He does not simply defeat enemies.
He takes what makes them dangerous and uses it for himself.
He did it with Whitebeard.
And attempted to do it with Boa Hancock and Trafalgar Law.
If this pattern continues, Sakazuki could eventually become the next major target.
Because Akainu’s Devil Fruit completes the image of Blackbeard as the man who breaks the world, burns what remains, and builds his own future from the ashes.
Blackbeard Would Strike During Chaos
If Blackbeard ever goes after Akainu’s Devil Fruit, he will not do it in a clean one-on-one fight.
That is not how Teach operates.
He entered Impel Down and Marineford during chaos.
Targeted the former Warlords after the World Government stripped away their protection.
So if Sakazuki becomes his target, Blackbeard would likely wait for the same kind of opening.
And the story may already be creating one.
In Chapter 1126, Blackbeard contacts Laffitte at the Umit Shipping headquarters while Laffitte watches the chaos caused by the Revolutionary Army’s supply blockade. Then Blackbeard tells him:
“… Well, stop observing the show… and get to preparing!!” — Chapter 1126
That line suggests Blackbeard is not just watching the Holy Land crisis.
He may already be preparing to exploit it.
Chapter 1149 pushes this narrative even further. When Imu possesses Gunko, Imu declares:
“At this moment… the Holy Land is a sea of fire.” — Chapter 1149
So now the pieces are there.
The Revolutionary Army is attacking the World Government’s supply lines.
The Holy Land is in crisis.
The Marines are currently stretched thin.
Catarina Devon may have a way to exploit Saturn’s identity after touching him on Egghead.
Garp gives Blackbeard leverage over the Marines.
Van Augur gives his crew instant movement.
That is all the setup Teach would need.
Akainu carries the one Devil Fruit that could complete Blackbeard’s arsenal.
He does not need to defeat the entire World Government.
He only needs one crisis big enough to reach Sakazuki.
One opening.
One moment where the world is distracted.
Then, just like Marineford, Blackbeard could walk into someone else’s war and leave with the power that changes everything.
Final Thoughts
So, is Blackbeard’s third Devil Fruit the Magma-Magma Fruit?
Right now, we cannot say it is confirmed.
But the evidence is starting to line up.
Blackbeard’s body is strange.
Luffy and Zoro sensed something unusual about him back in Mock Town.
Marco confirmed Teach’s body is different during Marineford.
Van Augur revealed that the Blackbeard Pirates are aiming for “the world.”
Vegapunk warned that the world is sinking.
The Holy Land is falling into chaos.
And Akainu holds one of the most destructive powers in the entire series.
That is why the Magma-Magma Fruit fits so well.
The Dark-Dark Fruit gives Teach control.
The Tremor-Tremor Fruit gives him destruction.
And Akainu’s Devil Fruit could give him the power to reshape the world after he breaks it.
That would not just make Blackbeard stronger.
It would make him a disaster with a plan.
And as the saying goes: “History is written by the victors” and Blackbeard is holding the pen.
So what do you think?
Could Blackbeard defeat Akainu and steal the Magma-Magma Fruit?
Or is Blackbeard’s third Devil Fruit going to be something even darker?
