Imu’s true identity is Vearth
We recently came to know the names of the Five Elders. They all have names of planets from our solar system and I think this gives the theory in the link above more validity.
Shephard Ju Peter = Jupiter
Ethan Baron **V. Nus**juro = Venus
Topman Valcurie = Mercury
Markus Mars = Mars
Jay Garcia Saturn = Saturn
In addition to the names of the ancient weapons, Uranus, Pluton/Pluto, and Poseidon/Neptune, this makes Earth the only planet from our solar system that is not tied to an individual or object.
However, in Chapter 244, the crew observes a statue on Sky Island that the Skypeians called “Vearth”! As you can see from the photo below, Vearth has similarities to Imu such as the big mouth that Imu used to defend themself from Sabo’s attack. They would look even more similar if that tall crown Imu wears was put on the statue.
Vearth is also described to be an object of “eternal” admiration and Imu had the “Eternal” Youth surgery performed on them. We know from Enel’s cover story that the Skypeians, Shandians, and Birkans were originally from the Moon. If the sky people worshipped such a figure, is it possible that Imu was once their ruler? If so, this could mean that Imu is also from the Moon. To hit the point home even further, Enel wanted to go to Fairy Vearth which ended up being the Moon. There’s also the recurring theme of the coming of dawn. It would be extremely fitting for Luffy, the Sun god, to overthrow Imu, the Moon.
