Elbaf was always going to be a long arc
Folks thought it was going to be Zou
I still think we'll leave in the middle to deal with Pluton and that Oda's saved Pluton's activation to start Ragnarok.
Imu clearly has Uranus, IMO, and Poseidon is Shirahoshi in Fish-Man Island.
If Ragnarok is connected to the Final War/Ancient Weapons, I want to see Loki making a move on Pluton with either Shiki, or Blackbeard. Ideally Shiki, since Teach's crew is already busted.
Shiki, Loki + Kidd Pirates is a legitimate force that can rival Cross Guild, who all have no love for Elbaf/Shanks. Bonus points if Moria somehow ends up on Shiki's crew, would be fucking hilarious.
Shiki: "Hey, Moria. You're than Bastard that went around turning all the former Rocks' Pirates into Zombies, right? To try to kill Kaido?"
Moria: "Tsk... so, what? You want to avenge your old crewmates, Golden Lion?"
Shiki: "No! I wanted to ally with you! Your power and scheming is perfect for what I'm trying to do! Hell, I wanted to thank you: I hated those losers! Always stealing my treasure, poisoning my booze, and trying to undermine me. I hate ever single Rocks Pirates alive, or dead! Thanks for killing them, and turning them into walking corpses, hahahaha! Exactly what they deserved!"
Moria: "...Oh. Well then."
Shiki: "Want to turn Kaido into a superzombie?"
Moria: "HELL YEAH!!!"
