[Theory] One Piece – Kaido: The Blood Of Oni

Kaido’s Lineage Factor/Bloodline Element has become a substantial aspect to the research conducted by Vegapunk and the Marine Scientists. The CP-0 have already confirmed that when Kaido was captured by the Marines he was experimented on with his Bloodline Element being used by Vegapunk to create the Artificial Devil Fruit that Momonosuke has consumed. Beyond the Artificial Devil Fruit there are also connections with Kaido’s Bloodline Element being used to experiment on the Numbers. The connections they share with Kaido are too substantial to ignore as separate. Additionally, the Dragons Vegapunk developed also appear to be based on his research into Kaido’s Bloodline Element. Further, there may have been other subjects that were used in the research into Kaido’s Bloodline Element, specifically, the Jailer Beasts of Impel Down. The blood Kaido possess has become an incredibly valuable component in the Marines research in creating “weapons” that can strengthen their forces and I find myself curious as to how else the Marine Scientists (and Vegapunk) have weaponized Kaido’s Bloodline Element. Will Kaido’s blood and ancestry become a core story thread going forward as the secrets of the past hidden away by the World Government are uncovered?

[Theory] One Piece – Kaido: Prisoner Of Punk Hazard

From the very start of Kaido’s introduction, we have known that he has been defeated as a pirate seven times, been captured by the Navy or his enemies around 18 times and has lived as a prisoner before. Kaido was tortured over a thousand times and was sentenced to death forty times and yet nothing done to him was able to kill him. From that introduction, we can surmise that Kaido was in his enemies hand’s for a significant amount of time. What we have yet to have revealed beyond why Kaido is so “unkillable” is where and when exactly he was held as a prisoner and by whom. When looking at what has been featured so far across the story since Kaido’s arrival onto the pages, I find myself compelled to believe that at one point in Kaido past, over 33 years ago, he was held as a prisoner on Punk Hazard and experimented on.
