Their personality:
-> They treated Sakazuki as if he were a mere child throwing a tantrum
-> They casually continued reading their newspapers while a Yonko arrived
A mere politicians can't be as composed as them when it comes to dealing with Top Tiers like that. Especially when you got a Yonko thanking them.
1 of them dresses like he's from a old ass samurai movie, where he's always playing with a sword.
2 of them have scars
1 of them looks like an old ass Sanji
All of them are huge ass mfs, with insane demeanor.
Their role:
- Top of the Celestial Dragons, the final villains of the series.
- Serve as Imu's hands, the guy who runs the world.
The Mareines /Kong/Admirals are just one of the many hands of the Gorosei, just as the Gorosei are hands of Imu. The hands of the King of the World, surely can't be weaker than the hands of those hands. Furthermore, they run things for him. I wouldn't ever put anybody in charge of a Government filled with top tiers on top tiers, if the ones I put in charge couldn't handle em.
What's stopping Sakazuki/Kong/Sengoku/Garp/etc from revolting against them??
