Oda is very great at pulling real world aspects and mixing them into One Piece. One is just a few of the locations in One Piece and what they are based on. Also some of the pirates real names are based on real pirates. Blackbeard or Marshall D. Teach & Whitebeard or Edward Newgate are based on the real Blackbeard also called Edward Teach or sometimes known as Edward Thatch who we know Blackbeard killed for the Yami Yami no mi. Newgate Prison was also a famous prison in London during the "Golden age of piracy." Whitebeards death is also probably a homage to Benkei ronin who was killed by a volley of arrows but remained standing after he died. One that was noticed by a friend was that some of Enels underlyings looked like goats and he considered himself a god. A verse from the Bible is "The Lord is my shepard" lol. Which makes sense. What are some other real world parallels you all have noticed?
