Yes but trying to kill him does not mean he used his strongest possible attack. The fact that imu has such a vast arsenal of combat abilities and weapons means he has a lot more to show. That's also true because he is obviously not going down this arc. So his future fight must have a lot more going on. He did not go all out against both Loki and Luffy. And keep in mind Imu is also nerfed right now because of his time limit.
he will never need to go all out against anyone in the verse In a 1v1.
He is legit killing anyone in verse if he pulled a nemesis+ stigma combo
