Nice to see Imu causing havoc and overwhelming so many so easily. We already saw Imu transform Dorry and Broggy so I guess there was no need for Imu to beat them, but seeing him maim Gerd and Stansen after already taking Broggy's arm is some good work for him. Of course the real highlight is him overwhelming Zoro then Sanji and doing that quite easily. Those two have a long way to go before they can do anything to Imu. Zoro busting out King of Hell to no avail, Sanji landing a solid strike to no avail and both getting handled efficiently followed by Imu moving on. Insanely disrespectful and amazing work from Imu, hope to see more against Loki then Luffy.
As for Zoro and Sanji, they'll improve this arc. Sommers and Killingham are out and about. Sommers left Zoro's location so even though Luffy told him to remember Zoro and Sanji already clashed with Killingham, we could get them swapping. I'd prefer Sanji vs Killingham Round 2 though, I want to see that trident in use and what other uses of his fruit Killingham can display. Sanji had a feeling things went too well, now he's gonna have to overcome a potentially amped up Killingham (the Omen ring seemed to still be above Sommers even after he healed, but we'll see). Sanji unlocking CoC now would be good. As for Zoro, I imagine he'll just be decently pushed and refine his usage of aCoC. Kinda weird position for him cause Imu is just too strong, but the Holy Knights seemed fairly manageable for where Zoro came into this arc from.
Can't wait to see what Loki has in store for Imu. I expect Imu to do amazing, but Loki has yet to disappoint. Luffy better get back into fighting shape soon cause things are going down. Gunko is probably free as well, so it'll be nice to see how much chaos the Holy Knights cause while Zoro and Sanji may be down for a bit.
