His plan may be of having Kuma arrive and then teleport Imu away.
This is interesting, but I think Kuma would have to surpass Imu's Haki in order to do this, since Law couldn't teleport Kaido and Linlin around due to their Haki dwarfing his.
I COULD see Kuma teleporting everyone out of the country if Imu and the WG actually take over Elbaph, and Luffy n Frens lose. It's possible they lose, Imu is accomplishing this without a single Gorosei, no Marine back up, and only two God's Knights.
Based on what we know, I think Imu still operates through the system of 20 established by the OG 20 Kings: 1 God, 5 Gorosei, then 14 God's Knights/God Blades
Imu took the arm off of Roger's Left Hand, put healthy Gear 5 Luffy down in a 1v1, and would have killed Luffy without Gaban interfering. Imu's taken Loki out in a 1v1, before he got back up.
This is without any Gorosei and a small contingent of God's Knights, and the two Magic Circles are still active (unless Imu blew up the one in Aurust when he spawned in), so Imu can spawn more forces in easily.
Elbaph is gonna need reinforcements to handle this shit.
I had Shuri helping the Crew destroy the Magic Circles after Imu got yeeted back to Marijoa, but it's entirely possible Shuri will need to help the Crew destroy the Circles NOW so Imu can't call in more reinforcements.
My hope is that Bonney turns Kuma into Gear 5, Nika Kuma (Nikuma?). I wanted this to happen in Egghead, but Gear 5 Kuma fighting Imu sounds fucking nutty.
