I think nerona king from 2nd world
Entity of Imu from 1st world
Imu is the name of Nerona king from the 2nd world.
Well, we can only judge by what we saw. Or else we can use the Narrarive decision card whenever it pleases us.
I am fine with whatever explanation you choose regarding why Kaido never used Haki burst. It doesnt matter either way.
Then Harald never was defenseless, since his body kept recovering even with his senses back. And the fact Loki easily overpowered Harald to the point of knocking Imu's influence temporarily out of him further demonstrates his power level.
He was defenseless because he dropped aCoC passive defenses which were the problem in the first place.
Both Shanks+Gaban encountered this just the same Roger+Garp did against DR Rocks.
aCoC passive defense is what neutralized attacks and didnt allow the damage to stick.
Regen is just a bonus that neutralizes mutilation, which only happens on characters with regen to begin with but it is aCoC which prevents damage from sticking.
And Harald removed that most important part and at that point, anything can kill him.
Overpowering him is not the reason for Imu's link to be interrupted.
Seems like Loki's power level wasnt enough for Shanks...
