Not with Zoro but in general. Cloning/Memory world transferring consciousness to bodies etc. I meant if Oda is willing to do that with egghead where is the limit?
Again i am only afraid that Oda will use Time Travel again. The idea of it is not great. Which is how i came to the scenario of Zoro being Ryuma himself. And i dislike it 100% lol.
Well here is what i believe regarding this Concept
Vega told us that Egghead is like a Teaser for Ancient Kingdom & it's pretty clear that the Invention that stands out the most on the Island is his Vega Records which allowed him to create those Six Variations of him
When we put the two informations together, we conclude that Ancient Kingdom definitely had it's own Records too & it was most probably much better & bigger
Where would this Ancient Kingdom that supposedly ruled the World put it's Super Mega World Records? An Island? A Small Cloud? Ofc not, we are talking something massive here, it's obviously "The Moon"
And thanks to Enel Cover Story, we did confirm that there was indeed a Scientifically Advanced City on The Moon & it makes perfect sense that it was created to hold World Records similar to Vega Records
What's even more interesting is that Birkans who had control over that Technology ended up leaving The Moon & going to Earth, we know that they recently lived in the Sky (Where Enel came from), but we also saw that they actually descended to the Sea before (As hinted by Enel who had knowledge that can only come from the Sea such as knowing that Luffy's DF is called a Paramecia Type or when we got confirmation that Weatheria where Nami was sent to by Kuma is home of other Birkans ... etc)
So where did Birkans settle in the past when they first descended? Oda answered that in same Cover Story when he showed a Scientist re-creating the same Automata that Birkans created on The Moon & he also loved looking at The Moon, so it's strongly suggesting that Birkans settled on that Island before. Do you know what Island is that? It's Vegapunk's Home Island (Where Franky was sent by Kuma)
Why am i explaining all this? Cuz i want to say that just like Vega Records allowed Vegapunk to transfer his Intellect to new Hosts, Ancient Records were also programmed to be transferred to a New Host, is there someone who was born Smart? As if he inherited Intellect from a Past Life? Yes, it's Vegapunk himself, that's how he became Smartest Man Alive!
But this is just one piece of the puzzle, this Idea of allowing such important Inheritance didn't stop at only Intellect, there is also a place that contains Genes & a person is chosen to inherit those Genes, there is also a place that contains Souls & someone is chosen to be born & inherit those Souls ... etc
That's why we have Big Mom who was born with Oars Strength, that's why we have Shirahoshi born as Poseidon, that's why we have Blackbeard & his Secret, that's why DFs get recycled, that's how Haoshoku Haki is being passed down
The Idea is that there are "Locations" that can store things that are normally impossible to store & these Locations then transfer their contents to certain individuals
For example, All Blue is basically a Sea that has All Genes, The Moon is same concept but for Intellect & Knowledge, Mary Geoise National Treasure is same concept but for Souls ... etc
So don't worry, there is no Time Travel or Characters turning out to be the same in different timelines, it's all about Inherited Treats.
