We know that Blackbeard main goal is to take over the world. With him likely wanting to use the one piece + joining the world government as his way to do that. Him wanting everything he can get his hands on like xebec before him
With Blackbeard “joining” the world government he’s definitely going to fuck them over just like he does everyone in his way to the top. Him learning about Imu is basically being his shortcut to the top without needing to go after the one piece anymore. Blackbeard using his new position to take Imu out and replace him
His final zoan fruit also likely coming from Imu
If Blackbeard does that I’d imagine he’s not going to just hide in the shadows like Imu but have it be well known that he’s king of the world. Spreading his influence far and wide. Probably putting his own men in places of power too
- Blackbeard replacing Imu obviously leader of the world and celestial dragons
- Kuzan potentially taking Sakazuki’s position and becoming in charge of the marines
- Shiryu becoming the new chief warden
- Laffitte maybe leading cipher pol and stationing himself in enies lobby
- The seraphim being his warlord equipment
If the world government already has Uranus and Blackbeard finds out the location of the other 2 by caribou he’s probably going to end up with all 3 too
On top of that red line Avalo Pizarro
Kaido (wano) -> Big Mom (elbaf) -> Shanks w/ buggy (laugh tale) -> Blackbeard (Mary geoise)
