The Egghead incident
The Egghead incident was set in motion
3 months ago.
Somebody told the World Government that Vegapunk was researching the void century.
As a consequence, the WG sent CP5, CP7 and CP8 to investigate Egghead but all their ships disappeared.
Then, the Gorosei talked to Vegapunk and revealed additional stuff and then ordered
Vegapunk's assassination.
They ordered CP0 to assassinate Vegapunk but he resisted.
So, the WG sent Saturn with Admiral Kizaru and different naval branches and raised their caution to total war imminent because they wanted to stop Vegapunk and expected anything.
Then, the Emperor Strawhat Luffy's ship suddenly appeared in their way to Egghead and they did not feel ok with this.
The chain of events is going to culminate tomorrow and the outcome will shock the world!
What will shock the world? Luffy defeating Kizaru because this was a WG mission and it was not supposed to be in the medias at all.
They saw an Emperor go to the island they were heading towards and instead of stopping, they shrugged it off and acted as if it wasn't a big deal. So yes, Luffy's Emperor status has to be reasserted here.
You can't contradict this because I literally wrote down what is written in chapter 1078.
