We all know that Blackbeard Pirates crew is excelling at sneaking/obtaining information stealthly because of their individual skills.
Shilliew ate the Suke Suke no Mi that gives its user the ability to turn himself and anything he touches invisible, making the user an Invisible Human.
Catarina Devon ate the Inu Inu no Mi, Model: Kyubi no Kitsune that allows the user to transform into a nine-tailed fox.the user gains the additional ability to transforming into other people, allowing them to impersonate them.
Lafitte is able of bypassing any security without being noticed, such has seen when he went to Mary Geoise to recommend Blackbeard as Shichibukai.
Gekko Moriah has the Kage Kage no Mi that is somewhat handy to hide in shady places and obtain informations, besides of robbing the shadows of his victims to raise his undead army.
Ok, but what such obvious informations have to do with the thread title? Where would Pudding fit on this? Let’s start talking about her: Pudding is the user of the Memo Memo no Mi, and as the name implies, it has the power of editing memories, which would be very useful for Blackbeard’s crew.
But she has a particular ability of this fruit which could be very handy if combined with Moriah’s Kage Kage no Mi: Memories Fil: Flashback. As we must remember, Purin was able of restoring the memories of the original owners of the holmies’s souls with this ability.
If she could that with the creations of the Soru Soru no Mi, she certainly can do the same with the shadows of the Kage Kage no Mi. Not to mention that the Blackbeard Pirates could take psychological advantage over her psychological issues and make her their puppet. Ok great, but where do I want to reach with this? Let’s think for a second: Moriah can rob the shadows of many persons to insert into his zombies. Pudding can restore the memories of these shadows. With this, Moriah could rob the shadows of many persons with important informations/secrets and Pudding would make the zombies gain access to such informations. To extract these secrets, anyone else of the crew could do the dirty job of torturing to obtain the required information. If that’s not enough to convince you of my theory, we can also remember of the misterious power contained within her third eye: the power of hearing everything, which could make her able of reading the Road Poneglyphs, making her importance to the story rivalize with Robin’s.
Anyway none of them would truly join because they want to. Moriah had no choice: was either join or die. In either of the cases the Kage Kage no Mi would end up at the hands of Blackbeard’s crew
Pudding would be kidnapped by the crew after the fall of Big Mom by the hands of someone else, possibly the Marines. After all, Blackbeard would not go on a directly comfront with another Yonko at full power.
