Big Mom vs Queen Explained: Chaos Breaks Out in Udon Prison in One Piece

The clash between Big Mom and Queen in One Piece’s Wano arc is one of the most chaotic and unexpected moments in the series. What begins as a prison subplot quickly escalates into a full-blown disaster when one of the Four Emperors storms into Udon. With her memories temporarily lost, Big Mom arrives not as a calculating pirate captain but as an unstoppable force driven by hunger and instinct.

This encounter becomes a turning point for multiple characters, including Luffy, who is training in Udon at the time. Queen, one of Kaido’s top commanders, is forced to confront a Yonko head-on in a desperate attempt to protect the prison. As shown in Eiichiro Oda’s manga, this fight is less about strategy and more about survival. The sheer power difference between the two creates chaos, disrupts Kaido’s operations, and sets the stage for major developments in the Wano storyline.

Why Big Mom Arrives at Udon Prison

Big Mom’s arrival in Udon is the result of her amnesia following a shipwreck near Wano. After losing her memories, she adopts a childlike personality and becomes fixated on finding food, particularly red bean soup. This leads her on a path that eventually brings her to Udon Prison, where she believes she can satisfy her hunger.

Her condition plays a crucial role in how events unfold. Without her usual strategic mindset, Big Mom acts purely on instinct, making her even more unpredictable. Despite her memory loss, her physical strength and durability remain intact, which makes her just as dangerous as ever.

This situation puts Queen in an impossible position. He cannot ignore her presence, but he also lacks the power to defeat her outright. The result is a chaotic confrontation that spirals out of control almost immediately.

When Big Mom reaches Udon, she quickly overwhelms the prison guards and begins searching for food. Queen steps in to stop her, transforming into his Brachiosaurus Zoan form to match her size and strength. Despite his efforts, it becomes clear that he is outmatched in direct combat.

Big Mom effortlessly withstands Queen’s attacks while continuing her rampage through the prison. Her raw power allows her to toss him around and destroy large sections of Udon without slowing down. The fight lacks the usual back-and-forth seen in One Piece battles, emphasizing the gap between a Yonko and a commander.

In a desperate move, Queen resorts to a risky strategy. He uses a powerful headbutt attack while Big Mom is distracted, temporarily knocking her unconscious. This moment is less a victory and more a lucky break, highlighting how difficult it is to deal with someone of Big Mom’s caliber.

Why This Battle Creates Chaos in Udon

The fight between Big Mom and Queen throws Udon Prison into complete disarray. Guards are unable to maintain control, prisoners seize the opportunity to revolt, and the entire facility becomes unstable. This chaos directly benefits Luffy and his allies, who are already working to take over the prison.

Big Mom’s rampage also exposes the weaknesses in Kaido’s system. Even one unexpected variable is enough to disrupt his operations significantly. The destruction caused during this encounter weakens the Beast Pirates’ grip on Udon, making it easier for the rebellion to gain momentum.

At the same time, the battle demonstrates the unpredictable nature of the Yonko. Big Mom is not even acting with intent to conquer, yet she still causes massive damage. This reinforces the idea that Yonko-level threats cannot be contained through conventional means.
