Thats my point. They name them something else. Zoro named those attacks differently. We didn't see Luffy hand vs pacfista
did u even read my post?
jet pistol, sanzen sekai and jet gatling all 3 are pre-skip attacks, meaning they were used w/o haki.
post skip:
jet-pistol used against pacifista>we didnt see the fist but sentomaru mentioned that luffy used haki so we know it was with haki. only thing we dont know is if it hardening or not. but if it turns out sentomaru wasnt referring to COA when he said Luffy used haki, my point still stands as i could still find two other move with haki and w/o haki. if someone looked all the past chap they likely can find more.
Jet gatling> was used against Ceaser, a logia. so ofc it had haki in it. plus Volume version corrected it with adding hardening(u can find the details in the Ryu thread)
Sanzen sekai> Zoro used it to cut pica and his sword was clad in armament hardening.
in all of these cases
name didnt change when used with haki.
so we at least have 3 attack that has both haki version and non haki version DESPITE being
same name.
so ur point is still wrong. we do have attacks that are improved version of old attack that has haki in it. like u mentioned those hawk moves has haki. BUT its not the rule that they name them something else when using that attack with haki.
So same name attack can have both haki version and non haki version. they can also have amped up version that uses haki too.
ISDS can be said to be a amped up version of Sanzen sekai.
