My issue is this:
Is the "Egghead Incident" supposed to be shocking to US, or the One Piece world itself?
During Vegapunk's announcement half of the people in this forum were openly yawning at the redundant information, while the characters in the series were all losing their damn minds.
Vegapunk being killed IN THEORY is a major incident. BUT, the only reason people KNOW Vegapunk died, is because of the Broadcast.
So, I have to believe the Broadcast is the Egghead Incident itself, that shakes the world of One Piece, while WorstGen whines about a lack of plot progress. Vegapunk dying would have changed the world, sure.
The foremost scientist in the world saying the world is about to flood, proving it, and then stating after that history is a giant lie, the only people who knew the real history were Roger and his crew THE PIRATE KING, and that whoever finds the One Piece will control the future is just NUTS.
I have viewed this arc as an amalgamation of Ohara, Sabaody, and Marineford: a dying legend, on an island full of ancient history, trying to flee while Kizaru and Kuma cause problems all over the place.
Egghead subverts Ohara by making it so the Giants protect the Ancient History, rather than falling to the Navy (Saul vs Aokiji). Rather than leave her mother behind, like Robin, Bonney takes her father, Kuma, with her.
Egghead subverts Marineford by making it so that the legend who reveals the One Piece lives on directly (Lilith survived to continue the Stella's legacy thanks to Atlas and Edison's sacrifices), rather than dies. In Marineford an Admiral kills a young man he hates, who is trying to protect an old man. In Egghead an Admiral kills an old man he's friends with, who is trying to protect a young woman (Vegapunk and Ace both die from wounds through their chest from behind).
Sabaody was supposed to lead to the Straw Hats going to Fishman Island, but, ended with Kuma teleporting the Straw Hats away from a man made of light (light's greatest weakness is gravity/magnetic force). Here, the Straw Hats have escaped the arc with Kuma while leaving Kizaru behind, and, like with Sabaody, seem set to go to the arc teased by the characters they met; Sabaody had Fish-Men leading the Straw Hats to Fish-Man island, while now the Giants are leading them to Elbaf. The central character to be rescued is a teenage girl who has been held captive by the WG, who are connected to a race hated by the WG (Bonney and Camie).
Egghead will subvert Sabaody by having the opposite of Kizaru: Gravity, or, Uranus, keep the Straw Hats from escaping. Kuma in Sabaody was an enemy who was secretly an ally. S-Bear is an enemy, who will become an ally thanks to Bonney, and teleport the crew from Uranus.
This allows Bonney and the Seraphim to have a legit narrative end to this arc. I think Oda is saving Saturn for later, for Bonney to fight in the future (Luffy already proved Saturn is too weak to touch him in a fight).
IMO, this gives Saturn and Kizaru a natural conclusion as well:
Imu is a genocidal bastard, and the Marines this arc SUUUUUUUUUUUUUUCKED ASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
GOD
THE MARINES
SUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUCKED
ASSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS
I think Imu is going to order Saturn to tell Kizaru to help him clean up all the Marines on the island who are below Vice Admiral. Maybe even the Vice Admirals. We haven't seen Doberman/Hound/Urban/Guillotine do jack shit this arc.
We know Saturn is willing to kill Marines who fail him and don't follow orders. Imu is a petulant man-child cooming over Vivi's great-great-great-great grandma screaming about Joy Boy. Imu can't get to Luffy right now, so? Take it out on the Marines who failed Imu.
Kizaru vs Saturn.
Huh. Bonney could turn Kuma into Nika-Kuma to teleport away from Uranus...
I've believed a crazy scientist would blow up the Mother Flame as both of Vegapunk's other labs have been blown up by crazy scientists (Caesar and Franky) most of this arc.
S-Bear teleporting all the Marines and Cipher Pol off the island after Saturn's nukes accidentally blew up the Mother Flame to save them from the explosion would be a cool God Valley callback to Kuma's Paws of Liberation saving all those slaves.
