I don't usually post theories, but I'm super hyped about this, since it is going to be Luffy's hardest battle (potentially of the entire series). Edit: This obviously has multiple layers, so trying to explain just the part won't make sense if the prologue and body are missing. Kaidou is the strongest being in the world, which is why Oda is having such a hard time coming up with a rational way for Luffy to win (comments Wano Kuni being his biggest undertaking). His original plan is to have an awakened Lucci (he learns the requirements of awakenings from Dr. Vegapunk) and an awakened Luffy being the minimum to take down Kaidou. The reason why Lucci will help Luffy is the mutual enemy of Kaidou. CP0's responsibility is to take down any macro threats (anything threatening an entire country or greater). Kaidou's alliance with Wano Kuni (a country feared for their battle prowess, but left alone since the villages war with each other and do not unite) is a clear threat that can easily topple Government countries. Lucci should (and probably will based on Oda's recent comments of not trying to outsmart fans that figure out his plans) be the one to show up in Wano Kuni. Tangent: this is why Stussy is at the wedding since Germa 66 and Big Mom having an alliance is a similar, but likely lower threat. Luffy did her job for her and she could stay in the shadows the entire time. The "breadcrumbs" for this are Lucci's who re-appearances in the manga (as well as Film Gold). Finding and putting together the clues can lead to the answer of what's to come. My side-tangent on Weevil is purely based on Oda's patterns. Luffy always, and will continue to "free" people that are enslaved by their environment. Most of the time, it is the main villain of the arc. For Weevil, he is being manipulated by his mother. Luffy "freeing" the illegitimate son is pretty much a guarantee based on Oda's patterns (a certain someone will completely disagree with this, but more on that later). The similar character traits and fondness of Whitebeard as well as a pure despise of Blackbeard will be the uniting factor. Luffy always changes people's opinion of him rapidly. Pretty much every arc has someone that miraculously takes a liking to Luffy. Again, more clearly established patterns that will continue through the rest of the series. Oda love leaving "breadcrumbs" on future events. The original plan to take down Kaidou is a minimum of a tag team of awakened fruit users (Luffy and Lucci; I'll clarify for new users if they don't know what I'm talking about). Now that things are being changed, Oda is likely changing some of his future plans as well. Based on the following picture (as well as the few pages we saw of him and his mother), we know that the illegitimate son is also actively hunting Luffy down. At the bottom of the page, we see the "WARNING" that he is on the loose. I'm thinking he hunts Luffy down in Wano and my original theory of their similar characteristics and mutual hate for Blackbeard makes them best of friends. Luffy will "free" him from his mother (just like how he saves/frees people in every arc). Thus, the combination of an awakened Luffy, awakened Lucci, and the illegitimate son will take down Kaidou. Weevil was probably supposed to be a separate incident, but now that Luffy is in the news, his informants will probably track down the activities of the other allies, namely the Nekomamushi group. He's too dumb to track people himself, so he either forces or pays for intel. An alternative is that he realizes the relation between Luffy and Marco, and gets the info from Marco (or maybe just overhears it when Nekomamushi talks to Marco). The only downside is that the just exaggerates the gap between Luffy (even when he gets an awakening) and prime Whitebeard, Roger dying from his terminal disease, etc. Whitebeard even in his old age could take down Kaidou 1 vs. 1 (until his terminal injuries made him age normally). So if this actually goes through, the super long-term theory is that Luffy gets an additional power-up of his gomu-gomu abilities when they free Dr. Vegapunk. Thus, this arc has to happen before his war against the Red Hair crew and Blackbeard's crew.
