One Piece consistently captivates fans with unexpected character returns, and it seems Big Mom may be next in this narrative. The Soul-Soul Fruit, known for its remarkable versatility within the Paramecia category, could potentially reveal one last hidden capability. This theory delves into the concept of Big Mom’s awakening allowing for complete soul transference—not a mere resurrection, but a deep, transformative escape that surpasses anything witnessed in the series thus far.
If this theory gains traction, Big Mom’s resurgence may not rely on her physical form, but instead require only her essence and a compatible vessel. Such a development could profoundly alter the landscape of the One Piece world once again.

The Mechanics of Soul-Soul Fruit Awakening and Big Mom’s Potential Return

The vibrant world of One Piece thrives on narratives of miracles, myths, and superhuman feats that defy the conventional boundaries of life and death. The prospect of Big Mom’s return is not merely a common plot twist; it arises from the very fruit that elevated her to the status of a Yonko—the Soru Soru no Mi, or Soul-Soul Fruit.
This theory presents an intriguing assertion: the awakening of the Soru Soru no Mi could be central to her survival post the Wano arc, following what appeared to be her demise. Rather than relying on science or cloning techniques, her survival could instead hinge on a manipulation of her own soul.
The powers bestowed by the Soul-Soul Fruit include the ability to control and extract souls, siphon lifespans, and fragment souls into smaller portions. This fragmentation allows the creation of “homies,” such as Prometheus, Napoleon, and Zeus. However, an essential aspect of these powers is the limitation that only fragments of a soul are used, while the original body maintains full consciousness. Awakening could redefine this boundary altogether.

Imagine the climactic moment of death: Big Mom, visibly destroyed and defeated. While her physical body may be failing, what if she possesses the ability to transfer her entire soul into another vessel? This vessel could be anything durable enough to encapsulate her essence—a piece of armor, a weapon, or potentially an object of significant personal importance. Instead of merely creating another homie, she could completely abandon her failing body to inhabit something new entirely.
For comparison, Brook’s Yomi Yomi no Mi illustrates that full soul separation is feasible. After his death, Brook’s soul returned to find his body, showcasing the capacity for souls to move freely. This concept aligns perfectly with the inhabitants of Oda’s world, suggesting that complete soul mobility could be within reach for Big Mom as well.
So, if Brook can enable his soul to traverse freely and the Soru Soru no Mi governs soul manipulation, one could logically conclude that the next stage of the Soul-Soul Fruit may well be total transference. This would represent a groundbreaking awakening—not merely control or fragmentation but an authentic rebirth through a chosen object.

Envision this scenario: as Big Mom lies defeated by lava at the height of the Wano battle, she activates her newfound power. Although her physical form is in decline, she diverts her entire soul into a hidden vessel—perhaps one she safeguarded over decades or crafted during her ascendance to Yonko. This object would then encapsulate her comprehensive mind, experiences, and strength.
This new iteration of Big Mom would differ dramatically. Although stripped of her formidable physical power, her essence would persist. The vessel could operate similarly to Brook’s skeletal frame, animated by pure soul energy, or enable her to inhabit new forms—whether temporary or permanent—by seamlessly transferring her soul. Additionally, her command over other souls might expand, allowing her to absorb and manipulate spirits, morphing into a spectral sovereign.
A compelling twist emerges when considering the fate of Mother Carmel. The enigmatic figure vanished without a trace, leading many to speculate that Big Mom may have consumed her. What if there’s more to this narrative? Could it be that Mother Carmel also utilized a form of soul transference to escape?

If Carmel escaped through similar means, it’s plausible that Big Mom unwittingly inherited knowledge of this technique when she assimilated Carmel’s power. This connection could unravel numerous mysteries within the One Piece universe, including cryptic reports from Elbaph and hidden manipulations behind significant events. Some earlier theories have even suggested a concealed figure might have orchestrated occurrences like King Harald’s demise—could this figure actually be Carmel, still exerting influence?
Moreover, it’s critical to consider that while Big Mom’s physical presence may have ceased to exist, her soul could still linger. She might be observing from the shadows, waiting and strategically maneuvering events through whispers, possessed objects, or allied homies.

This resurrection aligns with the core themes of One Piece, primarily those exploring legacy, will, and rebirth. It highlights how the defeat of a Yonko does not necessarily equate to the end of their influence. Just as Doflamingo suggested that the next era might rise from obscurity, Big Mom could very well emerge as a hidden orchestrator, subtly reshaping the world once more.
Initially, her return might not create a significant uproar. Instead, it could manifest through subtle, enigmatic shifts from former allies, inexplicable actions from her remaining homies, and new adversaries echoing her forgotten philosophies. The moment will eventually arrive when someone hears a familiar voice—a recognition of her enduring spirit. Big Mom would return, not as a risen queen cloaked in regalia, but as an indomitable soul refusing to fade into obscurity.
Concluding Thoughts

The Soul-Soul Fruit has long represented a formidable power based on fear and control within the One Piece narrative. However, should an awakening lead to complete soul transference, it could permit Big Mom to challenge the very essence of death. Her spirit would persist within an object, preserving her identity and capabilities, negating the necessity for a corporeal body.
This potential return would resonate more with a continuation rather than a mere resurrection—quiet, concealed, and ultimately inevitable. The Soul-Soul Fruit might indeed hold the secret to Big Mom’s second act in this grand tale.
