Seriously how many antagonist/anti hero groups are going to be there?
RHPs - Luffy gotta meet Shanks and show his strength
BBPs - Built as anti Luffy since before Skypeia
CG - Luffys rival Buggy and Zoros rival Mihawk
Marines - Akainu killing Ace and scarring Luffy
Gorosei - Nasujuro with the Shodai Kitetsu
Holy Knights - Garling and his retards
Who is going to fight who? How many will face off against SHPs? At least five groups have characters that can fight Luffy and/or Zoro:
RHPs - All SHPs can have a matchup
BBPs - All SHPs can have a matchup
CG - Only Zoro and Sanji and maybe some other SHPs can have a matchup
Marines - All SHPs can have a matchup (looking unlikely with how shit VAs have been this arc)
Gorosei - Luffy and Zoro can have a matchup
Holy Knights - Unknown, maybe all SHPs can have a matchup (though Dragons comment suggests that RA will be fighting or engaging these Holy Knights)
There are few opponents/encounters for Luffy and Zoro that are almost certain imo
Luffy - Shanks, BB, Akainu, One Elder (Warcury probably), Imu
Zoro - Shanks (not a fight but still because of shared Mihawk rivalry)/Benn, Shiryu, Nasujuro, Kizaru (if Akainu and Marines become an enemy), Mihawk
At the minimum BB and Imu for Luffy and Nasujuro and Mihawk for Zoro. But with so many groups how will Oda handle it without powercliffing the fuck out.
Did we have a BB reaction panel yet? Weird if only Aokiji is shown with a reaction panel from BBPs.
