Shanks haki being equal to old WB level is hilarious because of one non hostile clash where he held back is hilarious lmfao. You’re genuinely delusional if you think current Shanks won’t be able to do anything to Loki. You’re being far too carried away by the hype acting like he can low diff every top tier. Shanks strongest attack is hurting Loki
With that said, I’d like to reiterate that Loki is still obviously stronger from the info we have
Loki 14 years ago dogwalked HK harald where even base harald was portrayed to be equal of base xebec who in turn was portrayed to be on Roger/WB level.
Whereas old WB and Kaido were considered stronger pirates than shanks. Unlike loki shanks is extremely well known pirate.
Setting this aside both luffy and gaban confirm imu's haki being far above anything they have witnessed till date which includes shanks and nerfed loki is matching and enduring such high level haki attacks from imu and has yet to even use his hybrid mode.
Nemesis alone should be far above anything shanks can dish out.
