2. Detailing the Plan step by step
It is possible that some core members of the Roger Pirates are actively pursuing this final mission and seeking its success. I will explain this in the next few sections.
Inspiring the New Generation
We all know that no matter what is inscribed on the Rio Poneglyph, some people will only act out of selfishness like Blackbeard. This could be the reason why Whitebeard clearly stated that Blackbeard wasn’t the person Roger was waiting for.
It was necessary for the Roger Pirates to find the right person, and it is likely that no capable pirate during their era was suited for the job. They needed a certain event that would inspire a new generation of pirates that would ultimately result in a suitable successor. This all resulted in Roger turning himself in and proclaiming that he left all his treasure at “that place” during his public execution. Roger knew that he was going to die, so he made sure that his death wasn’t in vain but actually was the first step in their big plan.
Finding the right person
The next step in this plan, is finding the right person among all the candidates. The person who was likely responsible for this was Shanks. We know that Shanks founded his own pirate crew and rose to power and become a well-known pirate. Shanks travelled the world and saw many places and likely met a lot of people. His journey into East Blue could have been for the purpose of finding Roger’s successor. When he met Luffy, it quickly became clear that he had the willpower, and the spirit that Roger also possessed. Members of the Roger Pirates have even expressed that they see the same spirit in Luffy that they saw in Roger. Shanks ultimately chose Luffy to be the chosen person to complete Roger’s mission.
It is possible that Shanks his Straw Hat isn’t just a token that ties Luffy to the title of Pirate King, but it is also a sign to other members of the Roger Pirates that he is the chosen person. Some of the Roger Pirates Crew members have possibly set up post along the Grand Line on points that all the big time pirates will pass (Sabaody) in order to guide the possible successor. The first person to do this was Crocus at the entrance of the Grand Line, and later they met Rayleigh at the end of paradise at Sabaody. Rayleigh trained Luffy in Haki during the two year timeskip and assisted Luffy in preparing for the New World. Because of this, Rayleigh is responsible for helping Luffy another step further in his journey to the Pirate King title and the final island Raftel. It is possible that more members of the Roger Pirates will show up before reaching Laugh Tale, like Scopper Gaban.
