I do not own One Piece!
OBS! Made on crack! (read; REALLY late dogwalks, to much candy and crazy friendship!) And contains spoilers fot hose who doesn't read the updates!
This, dear folks, is my theory about;
Subject:Bartholomew Kuma and the Pacifista cyborgs.
Source/Inspiration: The last scene in chapter 561.
Theory:Alright. Vegapunk should have made made the Pacifistas impossible to defeate, at least in my opinion. He gave them powers which imitated powerful Akuma ni Mi abilities, such as Kizaru's laser. But that's not their ultimate attack! Remember, their archetype is Kuma the Tyrant. And Kuma means bear in Japanese, right?
Good. Now, imagine this scenario; Kuma runs against you with a lot of shoujo effects, such as a flower field, sparkles and heart with rosy cheeks! His arms is open for a big, big hug and he smiles as little girl in love!
Terrifying, isn't it!? Anyone would totally run away from that...
And, since the Pacifistas doesn't have Kuma's Nikyu Nikyu no Mi ability, Vegapunk could ad another element to this attack! I.e. Kairoseki. If the cyborgs were made in this metal, even Akuma no Mi user would be unable to flee from this powerful attack; The Bear hug.
One Piece is a hilarious serie, and I got a couple of more theories. 'Til then!
