IMU is Enel- What I actually mean is ELBAPH is Skypiea 2.0

When this guy landed on Elbaph the first thing to catch my eyes was the ring on his back. Enel had the same things but with drums instead of eyes and obviously enels was made of some kind of metal on his back while Imus is made of black flames.

After the last chapter I have decided to believe my theory whole heartedly. Because in Skypiea When Luffy first interacted with Enel he delivered the first blow. The actual first hit between the two of them was delivered Luffy in base form. My second theory is that Luffy might be Imus weakness that why he's even able to hit him but I need more chapters to be certain of this.
