Not a very long theory since everything is straight foward.
Biblical definition of the name coby: A diminutive of Jacob, Coby derives from the Hebrew Ya'aqov and later Latin Iacobus and means
“supplanter,” “Yahweh (God) may protect,” and “holder of heel.”
Japanese defintion of the name coby
: Supplanter, God's door, God may protect, tortoise etc
Even in English, Greek, Hebrew, Dutch, Swahili, Latin, Japanese it has the same meaning: https://en.m.wikipedia.org/wiki/Kobe_(given_name)
To add:
As theorised by others upon the forecasting in Skypeia, if there are 4 god devil fruits then, Coby will eat the Mythological Zoan Hito no mi Model: Earth God Kurma. Luffy ate the Mythological Zoan Nika Devil Fruit and gained the powers of The Sun God. There are stated to be 4 deities.. The Sun God, Earth God, Rain God and Forest God. Coby's name translates to "Turtle", and the World Turtle is known as the God of The Earth who protects the World. Just as Coby is a Marine who protects the World and his Hometown is called "Shells Town'.. For
Coby to equal the Pirate King, he too must step into the domain of the Gods.
Lastly to put the nail in the coffin for the theory we also have this:
Kurma, (Sanskrit: “Tortoise”) one of the 10
avatars (incarnations) of the
Hindu god
Vishnu. In this incarnation Vishnu is associated with the
myth of the
churning of the ocean of milk.
