Imu has to be so pissed at people in the world government if you think about it.
You built this whole organization! You and your 20 fellow Kings and Queens built this whole thing!
800 years later and Mu has these people living in pure luxury. He has rewarded the descendants of his allies handsomely indeed. Eating the finest foods, being disgustingly rich, having LITERALLY every desire they could possibly have catered too. They can hand OP devil fruits out to their slaves as if its a joke!
Mu even gives them actual goddamn authority to run shit. Just so they can have fun in their garden room, and play with the butterflies.
But EVERY TIME shit actually gets serious Imu has to handle it themselves.
Despite the fact that Mu gave the strongest guys and gals on their team literal immortality and bestow super hax on them, they need Mu to directly control them.
It makes sense that Imu killed Saturn by the way. People said that was to showcase how “cold” Imu was or some shit. Nah, it was the only reasonable reaction.
Luffy, his crew, and the giants? Would all be dead right now if that clown turned Emeth into scrap like he was told. But NO, he knew better. No shit Imu took away his immorality after that and fired his ass.
Do that shit at your work. Defy a direct order of your boss and it blows up in the entire company's face a few years later. Watch how you are treated.
Imu has legitimately been a GREAT boss in terms of villainous rulers in fiction. And still they get disappointment after disappointment.
If the World Goverment was not evil as fuck, I would legit feel sorry for Im at this stage.
They are carrying the WG so hard its not even funny.
