If you think about it, Imu is basically a Kaido that fights like Shanks
I'm not gonna lie, I'm really appreciating seeing him fighting. He's totally living up to the expectations we had on him, of an untouchable god-monster who seems unbeatable by any means.
And I say that because not only he seems impossible to damage. We see that his omen defense is nearly unbreakable, but also hit with a straight ragnir hit in the face + thorheim, he's just having a small drop of blood in his forehead. He's literally undestructible like Kaido but on a much larger scale AND he also goes for the kill instantly like Shanks!! him using omen and acoc even on small fries shows that he's a goddamn predator that doesn't waste time like the other tanks we saw.
It's crazy that he has stronger haki than Shanks, has stronger durability than Kaido, stronger hax than Luffy and yet he'll instantly destroy you before you can even notice.
He truly is the god of One piece. I am really satisfied of seeing him in action, idk why some people are disappointed
