But why Blackbeard wants Moria to join his crew? Doflamingo clearly stated that Moria is “too weak to be a Shichibukai”.

We all know that Blackbeard is a Specialist when it comes to Devil Fruits. He has done researchs on Devil Fruits for many years and I believe they are choosing Devil Fruits very strategically now. When Blackbeard met with Ace and invited him to join his crew, he said that he has already planned everything like he has already planned how he is going to be the Pirate King.

That certainly involves how he is going find the Laugh Tale. I believe Blackbeard currently doesn’t possess a Poneglyph or doesn’t know a way to decipher a Poneglyph.

Moria‘s Devil Fruit can be very useful for this purpose since he can revive dead people through shadows. The personality of that person could be changed but their skills remain the same. Just like Ryuma, his skills remained the same as before and even though his memories were faint and fading he still remembered his days in Wano and how he slayed a Dragon.

I believe Blackbeard is planning to revive someone from the past who knows how to decipher a Poneglyph or where Laugh Tale is. But in order to revive someone, they need the dead body.

I believe that’s the reason why Shiryu took the Suke Suke no Mi from Absalom. He can become Invisible now.

Just think about Blackbeard Pirates carefully:

1-Lafitte can hypnotise anyone and he has proven his success by infiltrating Mary Geoise.

2-Catarina Devon can shape shift into in any person. She is basically a nine tail fox.

3-And now Shiryu can become invisible. They are perfect for any kind of infiltration and they are clearly planning for it.

Furthermore Avalo Pizarro has the ability to merge with an island’s environment and manipulate it. Van Augur has the ability to teleport himself and others from place to place. The Blackbeard Pirates have the most subtlety devil fruits by far.

They could also revive legends from the past like Gol D. Roger. We really don’t know what happened after Roger was executed. Was he buried somewhere or was his body taken and hidden somewhere with tied security by the World Government.

Well just thinking about it make me wonder how dangerous Moria’s devil fruit can become. Imagine all the strong dead people revived and being on black side. Imagine Gol D. Roger, Xebec D. Rocks and Whitebeard revived and fighting for Blackbeard.
