Here is more Info guys from another member named Turrin over on NF ( His theory)
With the reveals this chapter I think we can safely guess who IMU is, and the answer is Asmodeus, an ancient Demon who was from the Lesser Key of Solomon, who once stole Solomon’s Kingdom from him, until Solomon eventually reclaimed it by recovering his magic ring and sealing Asmodeus.

Now aside from Sabo describing the throne room as hell and Asmodeus steeling a throne similar to IMU.
Why do I say IMU is definitely inspired by Asmodeus. Well Asmeodeus is described as:
“Asmodeus with the breast of a
man, a
cock leg,
serpent tail, three heads (one of a man spitting fire, one of a
sheep, and one of a
bull), riding a
lion with
dragon wings and neck”
Most of these iconography is very visible in the chapter:
Imu who is in the center looks the most Human, just like the center of Asmodeus does. Flames are also shown coming from his mouth with him swallowing them from Sabo:
IM also seems to have a dragon like tail:
The Gorosei also seem to fit Asmodeus’s animal like parts:
1) Saturn and Mustache Gorosei could easily be Bull and Sheep like Monsters
2) Bird Gorosei can easily be the Rooster aspect
3) The empty throne IMU sits on has Snake like Lions, and the final two Gorosei could also have these aspects or other aspects associated with Asmodues (I haven’t researched everything).

Also if we look at IMU’s eyes this chapter they get more rings when he gets mad an swallows Sabo’s fire exactly like the Jinn summoned in WCI arc:

And the lesser Key of Solomon’s symbols is now very clearly to me the symbol on the empty throne and WG insignia:
—-
We also must remember that Alabasta is very Arabian nights symbolic, so the Demon King of Jinn being Lilly’s enemy would fit very well on that level. It also would give us an idea that One Piece could be ether Solomon’s Ring equivalent or the Seal to imprison Imu equivalent.
Although Turrin seems to believe that the tails are more dragon like he still believes the theme of the devil is present here.
