Holy fucking shit
I'm not even lying
For the last month, I legit forgot the Revolutionaries existed. I completely forgot about Dragon... LOOOOOOOOOOOOOOL
People I can see saving Luffy:
On Elbaph:
1. Usopp. Bonney uses Distortion Future, Usopp becomes the Giant Warrior Sogeking, and lifts Ragnir.
2. Jarul. Same tactic, Bonney de-ages Jarul.
3. Jinbe. I would NOT be surprised if Imu has a water weakness, since Imu's power is Devil Fruit, and Devil Fruits are all weak to the Sea. We already saw Jinbe's Fish-Man Karate handle Imu's Maki Flames pretty well, and Jinbe really has done SHIT since Wano, Oda needs to give him some wins. Even if Jinbe can't defeat Imu, I think we'll see a situation similar to Marineford where Jinbe protected Luffy from a strong top tier in Akainu.
4. Nami. Nami is already fed up with Imu over the children situation and Shuri, and Oda has yet to expand on Nami's CoC she displayed after Wano when berating Luffy in the cage. While Nami obviously won't beat Imu, I think she could distract him.
5. Kidd in a Giant Viking Gundam. This is my biggest hope. Kidd owes Luffy A LOT for Wano, and he really hasn't done much to repay him. One Piece is a series that takes debts of honor seriously.
6. Loki. We've yet to see his Hybrid, and Loki realizes how valuable Luffy is in this fight, and also owes him for defending Elbaph.
7. Zaza, if she was a fan of Nika.
8. Kuma. Would be cool to see him save his savior, again.
9. Bonney herself. We know she can go Nika, and I want to see Imu's reaction to her in that form.
Off Elbaph:
1. Vivi. Vivi wouldn't be able to fight Imu, but her arrival would DEFINITELY distract him.
2. Shanks. I think he'll feel the Seal via Phantom Limb, and sense Imu's arrival.
3. Dragon. At this point, there really is NO reason for the Revs and Straw Hats to not work together and share information. The amount of connections between the two groups is insane, and Dragon was last seen stating the true war will start when the God's Knights are deployed. Dragon clearly has spies on the Red Line, aiding in his assault of Marijoa. He should be tracking God's Knight deployments.
4. Blackbeard. If Teach can use the Abyss through his Awakening, I think he might show up in Elbaph to protect it from Imu. I am of the mindset that Catarina and Augur, not Kizaru, fed Luffy on Egghead. I think Teach knows Luffy's value and wants to work with him.
5. Kaido and Big Mom. Low key the funniest/coolest one, I believe there's a chance Pluton sensed Imu's arrival on Elbaph, and activated, causing a volcanic eruption. If Pluton's activation causes Mt. Fuji to erupt, then Kaido and Linlin could be freed from their magma prison. Both of these characters can fly, and would immediately beeline to Elbaph. I've been waiting to see how Linlin will end up back in Elbaph, and it's entirely possible this is how. I also think it would be objectively hilarious, if Imu descending to the Surface is what caused Kaido and Linlin to get freed.
Edit: It's also possible Imu has a timer and has to get back to Marijoa at some point. If this is the case, we should learn this from Shuri when she fully recovers.
