Dragon and Sabo had no clue that the Gorosei had DF powers. Meaning the Gorosei don’t go around showing them off
I’m sorry what?
How does that prove anything? Dragon nor Sabo aren’t part of wg nor marines so they never been in presence of gorosei ever
we know characters in this series can sense how powerful characters are just from meeting them
Characters like Sengoku, Akainu, Kizaru, bunch of Vice admirals have been in front of gorosei and know how strong they are, and yet it’s still a fact that admirals are the strongest in WG
