One Piece Theories (Nami)

My Favorite anime is definitely One Piece. Now that we're in the stages of the final saga, my theories on what will come next and my view of certain characters grows and changes everyday. I can listen to other peoples theories all day and add them/connect them to my own thoughts. 

I would love to hear everyone theories on the series. 

My top theories mostly revolve around Nami. I feel she is the most important character of the whole show, even more important than Luffy himself. 

My most wildest thought is that Nami was born in the past and sent to the future by Toki. However I don't even know how to type out why I feel this way lol.

She definitely has some relation to witches, wizards, sorcerer's or however you would like to call them. Not only is her clima tact almost magic like, her ability to predict weather phenomenon is also very witch like. Also lets note how there have been moments within the show where she herself gets called a witch/sorcerer. Plus, she literally was trained by WIZARDS on weatheria about the weather! Her natural inclination with the elements is so intriguing. At times I don't know what to feel about her. Her weird ties with the sky islands along with fisherman island(Shirahoshi,Jimbe,Arlong), Alabasta(specifically her relationship with Vivi), Zou(she was literally gifted a national treasure worn by someone very important centuries ago), and I guarantee Elbaph will be very important for Nami lore. (Nami was once draw with wings, specifically wings from the Birka kingdom. Birka lineage has connections to Elbaph). She has so many small connections to certain islands you can't help but wonder about her lineage. Could she be from a sky island? I know people have mentioned she somehow might be a mermaid? I know the most common theory is that she's from royalty. Which that I don't doubt, however the real question lies is with her bloodline. My idea is that Nami comes from a royal bloodline of witches or lets just call them magic users for now. A kingdom that ruled possibly during the void century and was wiped out, hence my thought of Nami be born in the past and brought to the future by Toki. I believe she herself is like Shirahoshi in a way. Like how Shirahoshi is Poseidon, I believe Nami has some natural born ability that hasn't awaken yet. Obviously this ability revolves around the weather/the sea. Which if she was born in the past is more reason for her to be sent to the future to keep her out of harms way but those looking to get her. I wouldn't doubt that she's the only being out there in the world of One Piece that has this ability. It's not somethings that's passed down. She would be a prodigy. 

Ive been seeing recently discussions of Nami possibly being from the Nerona family, which has ties too Imu.

I could go on and on about this but Ive run out of brain fuel for now lol. But what I do believe 100% is that Nami will be the catalyst for whatever is to come. 

If anyone has any other theories on her or about one piece in general I would love to pick your brains!

Let me know what you think.
