And like i said, you put way too much stock in the regalia moves like they mean much.
Aokiji's attack names are all VERY simple (read "Ice____" every time). Oda uses specific japanese references for Kizaru. There is nothing that states they are any different from each other, just because one name sounds more impressive lmao.
Heres a "Regalia" move from Kizaru, and here is Kaido's Boro Breath, both blocked by Marco. What is the actual fucking difference lmao, what did they both accomplish? Luffy has canonically TANKED the latter multiple times.
