Why Oda revealed ''secret ruler Imu'' before finding OP?
If Imu was going to survive the story after finding OP, Oda wouldn't show him yet. He ruined the surprise if the plan was making Imu survive after finding OP.
Find OP, show the next target Imu with that.
Clowns don't know anything about story writing.
Oda literally says series will end after finding OP, dumb clowns argues vs Oda
Whatever fanfic you have, make that finish before finding OP.
Once Luffy finds OP, he will become the no.1 target by everyone just like it happened with Roger, he won't fight Imu while fighting other pirates at the same time.
As well as Oda wouldn't make Imu and Saturn hype Teach as well, then make him lose before them, thats retarded.
Some clowns don't know how to write a story.
Oda never make people learn what happened before an arc starts; we learn Robin's Ohara during Enies Lobby, Oden story during Wano, Imu flashbacks will be revealed during fighting against him.
