As we know, Teach wants to make Hachinosu a kingdom. Now that he has Garp, this is a big possibility.
This parallels how pre skip, Teach traded over Ace in order to get Shichibukai status. Status he used to raid impel down.
So if Teach intended to use shichibukai status to raid impel down, what does he intend to do with status as a WG king? Isn’t it obvious?
He intends to raid Mariejois. When he does so, he will be met with Imu and the Gorosei, who will no doubt put a stop to his rampage.
Imu will get massive hype, beating the shit out if a yonko. However I think Oda will use this as an opportunity to power up Teach and Shiryu. Imu, seeing Joyboy Luffy as the greater threat, will make a deal with Teach.
He will give Teach and Shiryu powerful mythical Zoans. The latter which shall have his Zoan fed to his sword via York’s help.
Ultimately, Imu will pit Teach against Luffy and pull the rug out under both of them by planning to attack them after they have an extreme diff fight with each other.
