S.A.D = System of Artificial Devilfruits

and I think almost all the inhabitants of Punk Hazzard know if Vegapunk failed experiment devil fruit ..

Vegapunk research closely related to the devil fruit, devil fruits like combine with inanimate objects (fruit Zoan type devil here is, perhaps so that they may live) .. and also about the elements of rock under the sea vessel, the ship is safe from the Sea King .. etc. .. and the last case is making devil fruit (we just know Vegapunk devil fruit that fails it is Zoan type?)

nah,, keep what to do with S.A.D??

ya possibilities: Vegapunk: experiments make fruit devil (momo case) Caesar Clown: devil fruit separate experiments (case smiey)

Vegapunk experiment that was 4 years ago, and Caesar is a person who does not want to be no.2 it then makes SAD (devil fruit artificial systems) .. Caesar inspired by Vegapunk failed experiment, and make the system associated with the devil fruit ..

smiley < likely this is one of the results of the SAD

just my opinion xD
