Forum:Samurai, Buggy and Vegapunk

i think.. buggy became a shichibukai for a reason.. vegapunk experiments.. the samurai must be the result of vegapunk's experiment in putting a devil fruit power in somebody else.. if i was not mistaken.. that samurai is killed by LAW.. but when he woke up he was sliced in to 3 parts?? am i right.. that makes sense that blackbeard learned the technique of getting devil fruit power from vegapunk.. maybe blackbeard discovered some of vegapunk's laboratory and adopted the procedure of extracting devil fruit's power.. any opinion guys?
