If its not because they're d's it might be because each represent a space thing
- Shirahoshi Poseidon Neptune
- Blackbeard a black hole
- Luffy the sun
- Vivi idk
They might be D., but there's more than this like you said.
-Luffy just embodies JoyBoy's vibe and, soon enough, his will.
-Blackbeard seems to carry Xebec's Will, to be the king of the WORLD, not just the Pirates king
-Shiraoshi and Vivi are related to Key countries that were said to harbor the terrifying ancient weapons. Roger stated that they were too early to complete their quest, literally because Shiraoshi and someone else weren't born yet! Only pitfall: Pluton's background hasn't been disclosed yet, to the point that it's not clear of it's related to Momonosuke and Wano or if the Shogun is "just" the one who can control Zuneisha to open Wano's border and free Pluton, to be used.
Maybe this was Lily's Plan, diffuse the Poignee Griff and hide Pluton while deceiving the world, making them believe that it was hidden in Arabasta (Crocodile searched It there, the WG won't go to Wano)
When will people realize that fire ain't shit? The supernova tanked that and way more during the raid. Fire is worthless for powerscaling purposes.
We can say that, if this Fire fist is strong as Ace's, they defended themself at least as good as pre-TS Blackbeard crew, who to be honest tanked also Sengoku's shockwaves.
We don't have ant other evidence on their strenght but we surely don't have any evidence on their weakness
Dude doesn’t get that Imu wasn’t hiding, he literally has everything he could ever want or need. There’s no point in doing anything
Imu and the WG don't fear anyone, head on, but rather thei fear to lose their grip, their privilege. They fear an unprecedented alliance of the free world that con overthrow them!
So, it's Imu's plan ti deceive the world and rule it, making people believe that they matter and can even propose to abolish the Shikibukai. That son of an ancient bitch
