Imu is not who we think he is SPOILERS AHEAD

The person we are currently seeing on Elbaph is not really Imu according to my theory, it is Imu currently being hosted by someone else

I believe his power as introduced in the series being "Devil's Fruit" literally means he became a devil, able to collect souls via contract, but the form we see is just one of many forms he can actually shape shift into.

Lets be real for a second, we saw Imu taking over multiple people's bodies, yet every single time he doesn't seem to remember what happened, and who he was fighting.

Upon arrival on Elbaph and just after his whole transformation into a non silhouette being , his first question was "Who is the King of this Country ?" a rather Odd statement because he already asked this question when he was possessing Gunko's body, or was it really him that was controlling Gunko's body ?

What if in fact Imu cannot possess someone if their families didn't have a prior contract with Imu, what if Imu made a deal with his own devil fruit, in exchange for his own life, he could take the soul of the 20 Kings, but he can only send their souls inside the bodies of their descendants

Why does it make sense that Imu had to come down himself from Pangea Castle ? because he lost Gunko and so there was no viable hosts for him to stay outside Gunko's body ? Can he jump from bodies to bodies or does he need to establish a contract with someone in order to become one of his Vessel ? if so why didnt he make that deal with others Holy Knights ?

Because he can't, he needs the blood of the 20 founders inside of the vessel's body to take over him , because he sends the soul of 1 of the 20 founders inside their bodies.

Is it Imu's true form ? No it's not, I don't believe for one second that in order to defeat Joyboy, 19 human families allied themselves with a demonic looking 40 feet tall demon looking person

This cannot even be a Lunarian body too, because he's twice King (Albert) size, he is almost one head shorter than an average giant, meaning this body is the body of a mixed race, a mixed race is absolutely not suited for Royalty, it would even be considered inter racial lineage and perhaps some kind of Bastard undeclared child drama around any royal family ever in the history of Mankind

With this out of the way, it means that this body we see curently was perhaps the former owner of the giant Straw Hat inside the frozen chamber, the only person Imu is sure to have defeated, Douzan.

Douzan is the only logical answer as to who is the real owner of this Body is, Imu has done nothing all throughout the story BUT take over people's body, and the first time we see him coming down to earth, he kneels the very same way he did when Emeth unleashed Joyboy's Haki knot, but then right after coughing up blood even though NO ONE WITH AN ABYSS MARK WAS KILLED he transforms into a demonic creature that holds no memories of what happened , all he knows is that he's been summoned, that there is a time limit , and that he must accomplish what he was summoned to accomplish

Which is odd, never would a King such as Imu go himself on the front line, he blamed Saturn for Joyboy's escape, but suddently when he sees Sommers and Killingham cut in pieces without a word he gives them power up boosts and tells them that Mu doesnt have any time to waste.

Another weird thing is that the current Imu we see on Elbaph calls King Harald his servant, but we know that Imu was inside Harald's mind the whole time he was fighting the guards and then Shanks and Gaban and finally Loki, so it doesnt make sense again that Imu asks who killed Harald, he should already know by now with all the informations gathered through the years of investigations

Which means the person we see currently has absolutely no memories of the past events, he just knows things that happened during his own time period, Imu summoned him but maybe its been 400 years since he summoned that particular body, or even more time , thats why Harald was able to become a vessel for Imu, because this body carries the blood of ancient Giants, and so does King Harald

in fact Harald was never Imu's servant directly, Harald was the servant of this former ancestor of his that shares the same blood, that Imu is using on Elbaph

After all Imu loves to test his weapons, just like he wanted to test Mother Flame the second he got his hands on it , the moment he realised he could summon Douzan on his own Homeland Elbaph, to kill and hurt his own race, Imu jumped on the idea to use Douzan's body even though it meants being hurt in the process of being used as a Vessel for Douzan

Imu would have been fine if he had managed to put Douzan's soul inside Harald's body like he intented to, Douzan would have then become the King of Elbaph to prepare the next generation of warrior soldiers for the World Government, and most probably Harald could have had a demonic form with Wings and Demon Tail like Gunko who I believe was possessed by one of her former ancestor

Imu still didnt show his true form, and this Nerona Imu is clearly not the Human Nerona Imu that we saw throughout the story, even if Oda makes it clear as glass, we all know he's going to twist the reveal the other way around as soon as people link Douzan to the body we see him using on Elbaph
