Decoding the Threat: Why Imu’s “Demon Form” Redefines One Piece Power Scaling

The One Piece narrative has entered its final, explosive phase, and at its center is the enigmatic ruler of the world, Imu-sama. Their recent, albeit brief, appearances have shattered all previous notions of power. The monstrous, shadowy silhouette—often theorized to be a manifestation of an ancient, terrifying Mythical Zoan or even a demonic entity itself—has demonstrated world-altering destructive capability, notably the obliteration of the Lulusia Kingdom. This event, executed by an attack resembling a planet-sized laser, confirms that Imu’s power operates on a cosmic scale, making them the ultimate antagonist for the Final War. The question is, which Devil Fruits possess the innate potential, beyond user strength and Haki, to Rival Imu’s Demon Form?

To stand against the sovereign of the World Government, a Devil Fruit must offer either a similar degree of apocalyptic power or a unique, reality-bending counter. We analyze five candidates whose abilities transcend conventional combat, offering a genuine challenge to the World’s “God.” This comprehensive anime review explores the theoretical peak of these formidable powers.

5 Devil Fruits That Can Rival Imu’s Demon Form

The following Devil Fruits are chosen not just for raw destructive output, but for their unique utility and ability to influence the very laws of the One Piece world, a necessity when facing a “god” of destruction.

1. The Hito Hito no Mi, Model: Nika (Human-Human Fruit, Model: Nika)

The Sun God vs. The Shadow God:

Monkey D. Luffy’s Mythical Zoan is the most direct conceptual counter to Imu-sama. Luffy is revealed to be the successor to Joy Boy and the living embodiment of the Sun God Nika, a figure who represents liberation, laughter, and a refusal to be bound by reality. If Imu’s power represents control, fear, and erasure (like the Void Century itself), Nika’s Gear 5 ability to turn imagination into reality—manifesting Looney Tunes physics—is the ultimate anti-control mechanism.

• Rival Potential: The Nika Fruit’s power is fundamentally reality-warping. The ability to grab lightning, cartoonishly manipulate objects, and resist impossible damage allows it to engage with Imu’s seemingly omnipotent attacks on an entirely different dimensional plane. Laughter is the perfect foil for Imu’s fear.
• High CPC Connection: The “Luffy vs. Imu” narrative is the most anticipated showdown, ensuring this Mythical Zoan remains a high CPC topic in every anime review and news cycle related to the Final Saga.

2. The Gura Gura no Mi (Tremor-Tremor Fruit)

The Power to Destroy the World Itself:

Once wielded by Whitebeard and currently in the possession of Marshall D. Teach (Blackbeard), the Gura Gura no Mi is considered the strongest Paramecia, with the capacity to generate planet-shattering quakes. Its power is simply the destruction of everything. It generates shockwaves that travel through any medium—air, water, or ground—and can literally tip the world on its side.

• Rival Potential: Imu-sama’s ultimate attack is seen obliterating landmasses. The Tremor-Tremor Fruit provides an equal and opposite force. An awakened user like Blackbeard could unleash seismic waves powerful enough to dismantle Imu’s shadowy form or shatter the very foundation of the Holy Land of Marie Geoise, matching the scale of Imu’s destruction with pure, unadulterated physical force.
• High CPC Connection: Discussion of Strongest Devil Fruits consistently features the Gura Gura no Mi. Its association with two legendary figures, Whitebeard and Blackbeard, guarantees high engagement in any serious power scaling discussion.

3. The Yami Yami no Mi (Dark-Dark Fruit)

The Black Hole of Power:

The Logia-type Dark-Dark Fruit, also eaten by Blackbeard, is unique and terrifying. It allows the user to summon and become darkness, which behaves like a black hole, drawing in and crushing all matter. More crucially, it negates the powers of other Devil Fruits by dragging their users into the ‘darkness’ of the void, effectively rendering them powerless.

• Rival Potential: If Imu’s Demon Form is indeed linked to an unrevealed, all-powerful Devil Fruit, the Dark-Dark Fruit’s power to negate all Devil Fruit abilities is the ultimate weapon. It offers a fleeting moment of vulnerability by forcing Imu to rely solely on Haki and physical combat, a decisive window in a fight against a seemingly invulnerable entity.
• High CPC Connection: The dual power of Blackbeard and the mystery surrounding his multiple Devil Fruits is a perpetual magnet for gaming and anime news, securing its relevance as a high-value topic.

4. The Ope Ope no Mi (Op-Op Fruit)

The Power of Eternal Youth and Space Manipulation:

Trafalgar D. Water Law’s Paramecia-type Devil Fruit is not about raw power, but absolute utility. The ability to create “Rooms” where Law has complete control over placement, orientation, and even the minds of anything inside, borders on the omnipotent. Furthermore, it holds the legendary power of the Perpetual Youth Surgery.

• Rival Potential: Law’s Awakening allows him to bypass conventional defense with internal organ damage and spatial teleportation. More abstractly, if Imu’s longevity is tied to the Perpetual Youth Surgery, the Ope Ope no Mi might hold the key to understanding or even reversing the effects of Imu’s own immortality, making it a critical strategic counter to the World Government ruler.
• High CPC Connection: The Ope Ope no Mi is consistently cited in discussions of the “most useful” or “most valuable” Devil Fruits, especially with its link to Law’s surgical expertise and the narrative importance of Imu’s apparent age.

5. The Toshi Toshi no Mi (Age-Age Fruit)

Manipulation of Biological Time:

Currently wielded by Jewelry Bonney, the Age-Age Fruit grants the power to manipulate a person’s biological age, either rapidly aging them to a point of extreme frailty or de-aging them to childhood. While its combat application depends on an opponent’s physical and mental state, its theoretical limit is frightening.

• Rival Potential: If Imu-sama is a being centuries old, as widely theorized, the rapid aging power of the Toshi Toshi no Mi could bypass Imu’s phenomenal physical defenses and Haki by targeting their biological weakness—their extreme, extended lifespan. Bonney’s power has also been shown to tap into imagined “future” abilities, such as briefly mimicking Gear 5 strength. If she can imagine a future where Imu is nothing but dust, the fruit’s true power could be a non-conventional, one-shot victory condition, a devastating counter to the supreme authority of the World Government.
• High CPC Connection: Bonney’s direct connection to the Kuma storyline and the revelation of her fruit’s true potential make it a hot topic, constantly drawing traffic from fans seeking One Piece news and theories.

The clash against Imu-sama will be the ultimate test of power in One Piece, demanding not just strength, but the unique, reality-bending properties of the world’s most formidable Devil Fruits.
