After reviewing the databooks, I jotted down some interesting points, only a few though. So just have a look if you havent read those yet. OP has five databooks until now, Red, Blue, Yellow, Green and Blue Deep. Red is called Grand Characters. Blus is called Grand Data File. Yellow is called Grand Elements. Green is called Secret Pieces. Blue Deep is called Characters World. Apart from Blue Deep, the other four were published before time-skip. And all databooks are made/supervised/checked by Oda himself. Red - 1. Luffy's belief, Luffy would say farewell to the straw hat when it's either that Luffy becomes the pirate king or Luffy dies, it must be one or the other. 2. Shanks' swordmanship is at the top level, Mihawk is the No.1 swordman. 3. Benn.Beckman is the vice-captain of Shanks' pirates. (this also stated in all the other databooks.) Blue - 1. Whitebeard was as strong as Roger. 2. Q: Would there be a new nakama joining the SH crew? A: It's up to Luffy. Yellow - 1.The reason why Luffy chose not to fight Bellamy that time is because Luffy thought it wasnt worth fighting against a person who didnt have a dream. 2. In general, there're two things deciding if a nakama is possibly joining: Timing and Luffy's Instinct. (you are welcome to read my thread new crew rule.) 3. Zoro deserves to be the vice-captain of SH crew. He is as strong as Luffy and obeys Luffy's orders unconditionally. 4. Nami is the internal captain on ship. 5. On the level of political function and power, Cipher Pol and Shichibukai are greater than the Marine HQ. Green - 1. Yonko = Marine HQ + Shichibukai (here I think Oda meant each one Yonko.) 2. Doflamingo may have signed a different contract with the WG as being a warlord. 3. In the original setting of Blackbeard's Yami Yami no Mi, he was even unbeatable to the three admirals. 4. There is a big possibility that a pirate from Roger's crew named Copper or Bronze appearing later in the story, since Roger is Gold and Rayleigh is Silvers. 5. It's very sure that there would be a pirate wearing eye-patch showing up in the final arc. 6. The only way so far to figure out Blackbeard's mystery is to think about Ace's words regarding BB's age. Blue Deep 1. It's almost impossible to find a ship that is big enough for Sanjuan Wolf. 2. Jesus Burgess' mask may be taken off some day and his face will be seen. 3. Shiki the Golden Lion was as strong as Roger, chapter 0 is a part of OP, but not in the main storyline, instead, it's the history that has happened in OP. (not the film strong world.) 4. Jewelry Bonney has a deep relationship with the WG. 5. Mihawk is older than Shanks, the two of them have the same constellation, Pisces. (LOL) 6. Speed Jiru, the commander of the 14th division, is the fastest man in the Whitebeard Pirates. 7. During time-skip, Robin was assisting the RA under Dragon and mastered vast knowledge. 8. The Pacifistas used in the Summit War of Marineford were trial products and each cost hundreds of millions of Belly. 9. Vista's swordmanship is strong enough to fight Mihawk. 10. Benn. Beckman is a super sniper elite. (also the smartest person in OP.) 11. Vivi as the representative of Alabasta is going to attend the World Meeting that is quadrennial. (IMO, Dragon & Luffy will be the hottest issue.) 12. Blackbeard has the strongest DF abilities. 13. It indirectly implies Sabo is dead, directly in Green Databook as a statement of fact. (I dont know why...) 14. Yasopp has a history with Vista. 15. Laffitte may be capable of entering any place. 16. Haoshoku haki has three levels (examples used are before time-skip): primary - Ace & Luffy (subconsciously); middle - Rayleigh (volitionally); advanced - Shanks (continuously).
