In this thread, discuss the power's and their themes.
Shichibukai is animal themed and also seven deadly sins. So discuss which shichibukai have which sins.
Also, discuss about Yonkou and if the titles rely on colors or facial hair.
The Navy doesn't really seem to have much of a theme besides ranks. So, just talk about if the powers of the Admirals depend on their devil fruit. Like Aojiki the Blue Pheasant - Ice (ice is blue)
Akainu the Red Dog - (magma possibly?)
Kizaru the Yellow Monkey (Not electricity, so… light?)
Ill put a list for the seven deadly sins down here too, and fill in the obvious ones. Also, I will put some with question marks for a guess.
Lust - ?
Gluttony - ?
Greed - Crocodile
Sloth - Moria
Wrath - Doflamingo? (Wrath on Bellamy and crew)
Envy - ?
Pride - Mihawk? (He is the world's best swordsman after all)
This is just a quick comparison for Yonkou
Shanks - Red Hair
WhiteBeard - (self explanatory)
I think Blackbeard will join the Yonkou instead of the Shichibukai since he has a facial hair theme.
