@AdmiralYonkouMt.Bandit:
I probably would've never caught that but that's just a name. If you look up Zheng Zhilong can't really say Shiryuu was based off of him when it comes to appearance.
I'm hoping confirms he's an avid Street Fighter fan.
Oh and by looking up Zheng it says his Western name was Nicholas Iquan Gaspard. Makes me wonder if Oda used that last name when he created General Gasparde from movie 4 (although the OP wikia says the name may be referenced from the pirate Gaspirilla).
I dont know Oda only use real life pirates name or based on their appereance too. I know Shiryuu is based on M.Bison in term of appereance.
And maybe in Gaspard case just like Edward Teach (Real Life BB) case.
Edward Teach name is used by WB, BB, and Thatch if i remember.
The wiki says a lot of things. Among others it puts forward the notion that Basco Shot is either named after tabasco or Vasco de Gama rather than Michel de Basco, a colleague of Zoro's namesake Francis l'Olonnais.
Haha. We should wait Mr.Odawesome to confirm everything.
