Off the gate I will start of by saying that I firmly believe that imu is or was the former poseidon. I know it sounds stupid but it makes sense. As we know fismen are discrimated against gard but did any of you care to know why?
Think of it both Fishman island and marejois have artifacts and monuments build in the name of the word DRAGON. Both have devices or abilities that shield their faces body from the outside air. Both a weird desire and respect for mermaids. The list goes on. The fact that that one of doffys relatives ventured out into the sea to capture one yet had his crew and ship destroyed but was some how able to survive in those deep seas before even being found always seemed weird to me..
But yes I believe that imu was poseiden since only Fishman are the ones that control the seas. It makes sense that an entity against joy boy was the one that cursed all devil fruit users from working affectively in water. In this instance the only one with that kind of control would be poseiden. To add its interesting that poseiden is the only LIVING ancient weapon. And coincidentally is the only ancient weapon that's role and ability can passed down to only MERMAIDS or MERMEN. Not regular Fishman like jimbe.
Now I know you are wondering why would imu be the first poseidon? And if she was why would she now discriminated against her own kind. My answer to you would be...... its because of joyboys (nikas) mistake. Hence the apology to the Fishmen people on the poneglyph. This is also why joyboya nakamura Zou was also cursed BY THE SEA to walk for eternity.
There is a direct correlation between nika and poseiden which is why when rodger found out that poseiden wasn't born he was under the impression that he was "to early" on his voyage. This hints like many other hints that nika was poseidens sovereign.
Now back to imu. This is only half of my theory since I need everyone to get this before I share my other theory. The word imu is IMU means "
I Miss You." The abbreviation IMU indicates a feeling of sorrow or sadness due to the absence of someone, such as a lover, family member, or close friend. It is typically used at the end of a conversation, when saying goodbye. However the word imu in Japanese means : HATE, despair, sorrow, loss.
However if we reverse the name imu to umi that gives it another added meaning. Umi: Umi is a babys name of mixed origins. Meaning “
sea” in Japanese and “mother” in Arabic, Umi is definitely related to some of life's most beautiful phenomena.
If imu was poseidon like my theory suggests then how is theire another one now while imu is still alive. That's because it was never stated that the previous poseiden had to die for another one to born many years later. Infact I can argue that imu/umi is mother nature in the form of the sea hence the name. Which means that imu lost its power being poseiden. And the way in which I think this happened was because I'm ate a devil fruit. We have the Noah, Adam tree and eve tree. The Adam tree in marejois while the eve tree is in Fishman island. These are Bible themes and these trees also again explains the ties of Fishman island and the holy land. Now that the Bible references are addressed I am of the belief that nika (joyboy) gave imu/poseiden a devil fruit to save her which resulted in her being stripped of her connection to the power of poseiden which resulted in her cursing the sea to those that follow nika (become devil fruit users). This is directly attributed to the reverse happening in the Bible with eve giving Ada. The fruit which result in GOD kicking them out of prosperity and being stripped of greatness.
That's the first half of my theory
