Hype tools for who? The bad guys? That’s not how this works lol
Oda typically uses bad guys as hype tools, not good guys. He won’t draw the Admirals as good guys just to draw them getting jobbed on lol. Oda is a very childish and predictable author in that way.
Now he may use Admirals to quantify other characters…like IE, Fujitora might fight S Flamingo while Zoro fights S Hawk or something, and therefore the scaling at that time would be Zoro ~ Fujitora depending on performance and outcome, but I doubt Oda draws the Marines betray the WG and then draws them getting jobbed on at the exact same time. The Marines fighting as allies alongside the pirates is just such a massive story event that there’s no way Oda will draw them jobbing.
