Middle opposite matchups: Teach & Luffy
Left high and right high opposite matchups: Buggy & Shanks
Left bottom and right bottom opposite matchups: Sabo & Akainu
Just a coincidence?
Left middle small and right middle small panel matchups:
Aokiji & Dragon
Garling & Silhouette
Koby & Imu
There is a history for every of those matchups except for Garling & Silhouette, and Koby & Imu.
Aokiji's Garp history might lead him to fight with Dragon as well, we know BB pirates also fought Revolutionary army before on Baltigo.
Will Koby play a part in Imu's fall? That would be interesting as well. We know Koby saved Rebecca before, perhaps he will play an important role in saving Vivi from Imu?
