Huh??? So BB is after Imu??
Man With Burn Scar, Blackbeard, Imu & Akainu are all gonna be Main Four Villains of this World War
In Order i Mentioned them (So Blackbeard is gonna be Fall couple Chapters before Man With Burn Scar or possibly same Chapter)
This is it, it's World War that will include all Major Factions & Oda will focus on drawing almost every Relevant Character
Man With Burn Scar + Blackbeard will be known as Most Dangerous Pirates Ever
After that, there is gonna be Elbaf Arc which will only focus on Giants & SHs, it's gonna be a Skypiea-Like Arc where Oda only focuses on Nine SHs & their Dreams, while exploring Vikings Culture which is the entire reason He wanted to draw this Manga in First Place
I know you guys wants Blackbeard to be Final Villain or Imu or dunno
But God of Elbaf was mentioned before any of these Characters
Also Man With Burn Scar, Blackbeard, Imu & Akainu stand between Luffy & finding Laugh Tale
However, Final Villain is the Guy standing between Luffy & his Secret Dream
Currently They are fighting with Yonko, WG & Marines for something that Roger already achieved
God of Elbaf is the reason Roger Failed to Activate One Piece, not Blackbeard or Imu or anyone Introduced so far
