【What if Joy Boy and Imu are actually brothers…?👻】
There may have once been a boundary like this during the Void Century:
I(1)mu(6)
Ni(2)mu(6)
Sa(3)mu(6)
Yo(4)mu(6)
Go(5)mu(6)
Imu as the eldest brother. And the fifth brother, "Gomu", could actually be the one who awakened Nika’s "Rubber" body power—Joy Boy himself.
What if their mother was “Ma-mu”?
That would also make it possible that the mother of these brothers was a woman who had relationships with many different men, like Big Mom.
So in that case, the eldest son Imu would have Mam as his mother, and the king of the Nerona family as his father.
And Gomu—Joy Boy—would also have Mam as his mother, but a different father. Maybe someone from the D bloodline.
And I think the face of this mother, Mam, may actually be what Oda-Sensei drew in the author comment section of Volume 62 as the “Mother of Humanity.”
And the line Oda-Sensei wrote there was:
“Humanity is family.”
So far, the story has suggested that Imu and Joy Boy were enemies—but maybe, originally, they were actually brothers.
That’s something you could even infer from Oda-Sensei’s comment there.
