On Whole Cake Island we got to know that Sanji & his brothers were genetically modified to become emotionless super soldiers at birth.
However due to a drug Sora took to prevent her children from becoming emotionless, only Sanji failed to show results of getting genetically modified albeit at the cost of keeping his emotions unlike his brothers.
The consequences of this however, were huge as it meant Sanji had to live the majority of his childhood getting discriminated against as a failure and was even locked away in a dungeon and later disowned & discarded by Judge.
Sanji had to go through all of that hardship solely because he was deemed to be a normal human without the same disposition and physical capabilities as his siblings. However, is Sanji really just a normal human? And did his genetic modifications really fail?
The illustration below shows how Sanji compares to his brothers, emphasizing both their differences and similarities:
From the above diagram, from a functionality test perspective, using Judge’s configuration as our test case, it’s abundantly clear that Sanji fails to meet the criteria of Judge’s ideal superhuman. However, even so, you’d notice that Sanji shares a fair bit of similarities with his brothers, most of which are unique to them in the whole verse and even within their family. So even though Sanji doesn’t possess the exact same disposition or characteristics as his brothers, I think these similarities prove that he was also affected by his genetic modifications albeit not in the same way his brothers were.
- Summary of similarities Sanji shares with his brothers
- Intense lust towards beautiful women
- On Whole Cake Island, after the Sanji vs Luffy fight, all of the Vinsmoke royal family members were present at the time however, only Sanji’s brothers expressed lust towards Nami in the same way Sanji usually does.
- Ability to use irregular abilities without a devil fruit.
- It is not normal for characters in one piece to be able to summon fire, light, electricity etc. without having done so via some devil fruit or something.
- Curly eyebrows
- Both Sanji and his brothers’ have curly eyebrows with a shape akin to the patterns that appear on regular fruits when they become cursed (I don’t think it’s far-fetched to infer that the source of this pattern appearing on regular fruits after they get cursed is due to the genetic structure of said fruits having undergone a change)
- Curly eyebrows in the world of one piece are referred to as a taboo & the child that has it is deemed as cursed as was the case with Duval.
- According to what Oda stated in SBS vol. 7, to a response to a question with regards to why Sanji’s eyebrows are curly, Sanji’s eyebrows are not ordinary.
- Intense lust towards beautiful women
Now even with the above similarities Sanji shares with his brothers, I’m sure there are still a few folks that aren’t convinced that Sanji was affected by his genetic modifications and the source of this conflict is most likely as a result of Oda’s answer to a question regarding the vinsmoke siblings hair color in a recent SBS.
