Theory The Soru Soru No Mi's Final Ability, Full Soul Transference

#1
Hey everyone, I’m back with another theory! This one’s an old favorite of mine that I first came up with during the Whole Cake Island Arc. I can’t recall if I ever shared it on sites like the now-defunct Orojackson.com, but I’m excited to revisit it here. As the title suggests, this theory explores what I believe could be the final, ultimate ability—or perhaps a desperate last gambit—of the Soru Soru No Mi.

As you know, the Soru Soru No Mi grants its user the power to manipulate souls. This includes stealing lifespans from others and embedding fragments of their own soul into objects or creatures to create homies—like Zeus, Prometheus, and Napoleon. Under normal circumstances, the user only invests small pieces of their soul, retaining full control over their homie network while their consciousness remains anchored in their physical body.



But what if, in a life-or-death scenario, the user could go all-in and transfer their entire soul into a single vessel as a final act of survival?



I’ve always seen the Soru Soru No Mi as a superior counterpart to Brook’s Yomi Yomi No Mi, much like how Oda described Akainu’s Magu Magu No Mi is a more powerful version of Ace’s Mera Mera No Mi.



Beyond reviving its user from death, the Yomi Yomi No Mi allows Brook to fully manipulate his soul, detaching it from his skeletal form to move freely. This got me thinking: if Brook’s fruit can handle a complete soul separation, why couldn’t the Soru Soru No Mi, a seemingly more advanced soul-based fruit, do something similar?


How It Might Work

Imagine the user facing imminent death, with no other options left. As a last resort, they pour their entire soul into a chosen inanimate object—a vessel of their making. This process would abandon their original body, leaving it as a lifeless shell. Unlike typical homies, which only carry fragments of the user’s soul, this new vessel would house their full consciousness and personality. Much like Brook, the user would become functionally immortal—able to persist as long as their chosen vessel remains intact. Destroy the vessel, however, and their existence ends.


The Implications

Now, you might be wondering if this theory means I think Big Mom could return. Rest assured, I don’t believe she’s coming back—no need to panic! Instead, I’m pointing the spotlight at another potential Soru Soru No Mi user: Mother Carmel. In a previous theory, I speculated about a shadowy figure orchestrating events behind the scenes, possibly tied to incidents like King Harald’s death in Elbaf. I propose that this hidden manipulator could be Mother Carmel herself, having used this full soul transference ability to survive in secret all this time.

Whole theory made useless by this last line.
BM never ate the Soul Fruit. If she has those powers, it's because she ate the previous user, Mother Carmel. If Carmel were still alive, BM wouldn't have the same DF.

You'd have a greater argument if you suggested that the Soul Fruit allowed Carmel to maintain her personality even after death by cannibalism, thus possessing BM, which gave rise to the Linlin/BM mental split, and if you proposed that it's thanks to Carmel's knowledge of this DF mechanic that BM survived her defeat in Wano, either transferring into someone else (Kaido-BM-Carmel chimera inbound?), or similar shenanigans.

Really cool idea!

Reminds me of essence transfer from Star Wars Legends.

I was thinking that too.

In the Darth Bane novels, he used essence transfer on his apprentice but she finally beat him through willpower to retain her soul, however she retained some of his characteristics like a twitch in her hand.

So if your take works then we could get BM taking over Kaido but retaining some of his personality traits.

Interesting Theory, i also can agree with this,
I think all DFs have a Scaling, basically how much Power you wanna use,

For example, Enel's Power scales with how much Voltage He wants to Use, other Logia work in Similar way,
Even likes of Yami Yami No Mi, scale with how much Gravity Blackbeard wanna apply,

Same goes for Paramecia, all DFs Scale similar to Kilo Kilo No Mi, such as Burgess & how much Strength He wanna apply, Luffy & how much He wanna Stretch, Robin & how much Copies She wants to make, Law & size of his Room ... etc

Big Mom's DF too have a Scale, and hers as you pointed out clearly relies on how much Soul She applies, and just like any other DF, there is a Limit (Even if it's a very High One), so it makes sense that Soru Soru No Mi's Limit is using the entire Soul

Tbh, it's clear that Jarul is hiding something, and after He said He likes old women, it's hard not to imagine Carmel having a hand with all of this, so maybe there is indeed a Homie with Carmel's entire Soul somewhere in Elbaph,

I'm suspecting Sword stuck in Jarul's Head might be a Homie now,

You theory will connect a lot of things if Carmel becames a Mosa Homie. The way she treats Loki is the way she treats any other kids. The tragic moment might be her being eaten by Big Mom.

She might be the architect behind the Loki-Lola marriage. She convinced Harald that this marriage will benefits both nations. Since Harald already connected to World Government, this will put Big Mom aligning with World Government too. World Government wanted Big Mom to become a marine since she was a child. So Big Mom accepts the proposal and thinking this is the great opportunity to gain the giants force, so she can finally dominate the world. However Lola noticed this marriage will destroy Big Mom's dream because her great sense sees through Loki's mind. In order to protect Big Mom and her family, she rejected the proposal and ran away. In Thriller Bark, she didn't seems to show any hatred to Big Mom and think Big Mom might be some sort of help to the Strawhats. She didn't run away just to ruin Big Mom's dream but to save it?

That's really good detail that you pointed out, Lola was introduced desperate to get Married & it's not like She was too picky, why would all BM Kids agree to Marry except her, especially after Big Mom implied that She wasn't gonna betray Giants like Germa, She really wanted to Ally with them

Lola seems to have refused that Marriage to protect Big Mom,
Also Harald was clearly against Piracy & an Ally of Holy Knights (I'd even dare say that Harald is to Shamrock what Roger was for Shanks),

How would this Marriage benefit Harald? Just like BM thought it wd make her Strongest Side among Yonko, Harald probably believed that this Marriage would make Elbaph surpass other Giant Nations, forcing them or persuading them to join as well, basically Uniting the Giants (Similar to how Judge wanted to use that Alliance to rule North Blue again)

But after that, Harald probably intended with Help of Holy Knights/WG & Alliance of Giants to actually turn against Big Mom (Something that all Giants wd appreciate as well), and take over Totto Land, turning it into Country of All Giants, hence why Lola refused the Marriage

The reason BM was able to gain the Soru Soru no mi ability is because the original body of the previous user is destroyed or eaten to be specific. Mother Carmel transferring all her soul to another vessel means she isn't tied to the Soru Soru No mi anymore, she just became an ordinary homie similar to Zeus.
