The One Piece anime has been building up to some incredible moments in the Egghead Arc. Fans who read the manga already know what's coming, and it's absolutely insane. With the One Piece anime entering a seasonal release era, a lot of the remaining Egghead Arc has to be animated quickly.
The tale takes a radical turn with this arc. These sequences must be powerful; therefore, the animation crew has their work cut out for them. Let's dissect the 10 most anticipated scenes that the One Piece anime still needs to feature.
Greatest Egghead arc moments to come in the One Piece anime
1. Zoro and Nusjuro's clash

The One Piece anime will showcase an incredible sword clash between Zoro and one of the Five Elders. Nusjuro charges straight at the Thousand Sunny to destroy it, but Jinbei throws Zoro directly at him. The two warriors meet mid-air with their blades clashing violently. Here's where it gets interesting, both fighters immediately recognize each other's swords. They're both wielding cursed Kitetsu blades.
The greatest Egghead Arc moments include this brief but intense exchange shows that Zoro can actually hold his own against a literal god. Their blades spark and repel each other with incredible force. Zoro yells for everyone to escape while he and Jinbei handle things. It's a short scene, but it proves the Straw Hats have reached insane power levels.
2. Vegapunk's broadcast reveals the world will sink

One of the greatest Egghead Arc moments that kicks off the chaos is Vegapunk's shocking announcement. The One Piece anime will show the entire world listening as the scientist drops a bomb, he tells everyone that the world is going to sink into the ocean. People everywhere react with panic, disbelief, and fear.
In Mock Town, pirates laugh it off as nonsense. Water 7 citizens question how rising tides could mean total destruction. But Doflamingo in Impel Down? He's cackling because he knows it's true. He even tells Magellan that most cities will sink if the sea rises just five more meters. The broadcast sets up everything that follows. It's the moment where the stakes become global, and everyone realizes the world is ending.
3. Nusjuro cuts the Labophase in half

The One Piece anime needs to go crazy with this scene's animation. Nusjuro breaks free from the giants' grip and jumps high into the air. Then he unleashes a slash attack so powerful it defies logic. His blade cuts through the entire Labophase structure like butter. We're talking about a massive island-sized facility getting sliced clean in half.
One of the greatest Egghead Arc moments includes this display of raw destructive power from the Five Elders. Seraphim and Cipher Pol agents fall from the sky as the structure splits apart. Marines below scramble to catch them. This single attack shows why the Elders are considered the World Government's ultimate weapons. The scale of destruction is absolutely bizarre and proves they're on a completely different level.
4. Vegapunk reveals Roger's full name

The One Piece anime will broadcast another world-changing revelation when Vegapunk speaks Roger's complete name. He announces to everyone listening that the Pirate King was Gol D. Roger. Most people didn't know about the “D” in his name. The World Government had hidden it by changing it to “Gold Roger” in all official records.
This is one of the greatest Egghead Arc moments because it connects Roger directly to the ancient mystery. People all over the world are screaming wildly, confused. Even if they do not understand what the “D” stands for, everyone feels that it is important. The pirates themselves are puzzled and start questioning whether Roger was more than they thought.
5. Atlas's sacrifice

One of the most emotional and greatest Egghead Arc moments happens when Atlas makes her final stand. The One Piece anime will break hearts with this scene. Atlas knocks out Lilith to hide her from York's surveillance. Then she flies straight at Nusjuro to stop him from catching the Thousand Sunny. She grabs the Elder tightly, and her grip doesn't loosen even after his sword cuts clean through her entire left arm.
Atlas looks at him and tells him that she is performing a service on the house. Then she detonates herself while still holding him. The explosion is massive. The entire Straw Hat pirate crew watches and grieves. However, Atlas's sacrifice gives them enough time for the ship to use Coup de Burst and flee. It's a heroic death, demonstrating how much Vegapunk's satellites wanted to assist Luffy's crew.
6. Emet emerges and punches Warcury

The One Piece anime will deliver an incredibly satisfying moment when the Iron Giant makes its comeback. Warcury charges at the Giant Warrior Pirates' ship to ram and destroy it. Everyone thinks they're done for. But then Emet explodes out of the ocean like a kaiju. Water sprays everywhere as its massive form rises up. It winds back and punches Warcury so hard that one of his massive tusks breaks off and flies away.
This is genuinely one of the greatest Egghead Arc moments because it's the first real damage dealt to the Elders. Everyone watching is shocked. Luffy especially freaks out seeing the robot move. Emet's return changes everything and gives the Straw Hats a fighting chance to escape Egghead alive.
7. Luffy and Bonney defeat Saturn together

The greatest Egghead Arc moments include this powerful team-up attack. The One Piece anime will showcase both Luffy and Bonney in their Nika forms fighting side by side. Saturn jumps onto the Giant Warrior Pirates' ship to stop them. But Bonney has recovered her strength and transformed again. She tearfully denounces Saturn as a false god, screaming about all the pain he caused her father, Kuma, and mother, Ginny.
Then she and Luffy unleash simultaneous devastating attacks on the Elder. The combined assault is so powerful that it literally blows Saturn to pieces. His body explodes, and he falls toward the ocean. Kuma watches with a smile as his daughter gets revenge. It's an emotional and action-packed payoff to Bonney's entire character arc in the One Piece anime.
8. Saturn's death by Imu

What happens when you fail Imu is depicted in one of the darkest and most memorable Egghead Arc events. This moment in the One Piece anime will frighten viewers. On Egghead, Saturn abruptly drops to his knees. His body begins to leak a black fluid that resembles ink. He understands what’s going on right away, he is being punished by Imu for allowing "Joy Boy" to get away.
The Vice Admirals around him panic and don't know what to do. Saturn begs desperately for mercy. He tries to explain that the Nika fruit's power was too unpredictable, but Imu doesn't care. Saturn's body starts shriveling up like he's aging rapidly. Then he explodes violently, leaving only a skeleton behind. The Vice Admirals watch in absolute horror. It reveals that the Five Elders serve someone even more terrifying.
9. Bonney transforms into Nika

The One Piece anime will blow everyone's minds with Bonney's incredible transformation. Mars attacks the Giant Warrior Pirates' ship with flames. Luffy returns to Gear 5 after eating and asks Bonney to help him fight. But she's scared because the Elders are too powerful. Luffy tells her he believes in her powers and that she can do it. This encouragement triggers something in Bonney.
She remembers Luffy saying Gear 5 is his most free form. She uses Distortion Future: Atashi Ga Ichiban Jiyuna Mirai and transforms into her own version of Nika. It's one of the greatest Egghead Arc moments in the One Piece anime because the Drums of Liberation play for both of them. The Iron Giant senses it underwater and reactivates. Bonney's white hair and Nika form look amazing.
10. Emet releases Joy Boy's Haki

The number one spot for the greatest Egghead Arc moments goes to this absolutely insane scene. The One Piece anime will need movie-quality animation here. Emet unties a knot inside its body that Joy Boy created over 800 years ago. A massive burst of Haki explodes outward from the Iron Giant. The shockwave is so powerful that it knocks out every single Marine in the fleet. Even the Vice Admirals collapse unconscious.
But it gets crazier. The Five Elders are forcefully reverted to their human forms and teleported back to Mary Geoise against their will. Only Saturn remains on Egghead. The Haki is so strong that even Imu feels it and nearly collapses in the Flower Room. It's revealed that Joy Boy stored his own Haki to protect someone in the future. The Thousand Sunny lands safely because of this ancient power.
