Didn't he literally use wings in current chapter? For Sanji?
Kaido’s epithet is LITERALLY “100 beasts Kaido” so the question is, does Oda want us to literally care that Kaido is called “100 beasts” or is there an actual meaning here that Oda wants to convey outside of the very specific words “100 beasts”
In the Viz, Kaido’s name is translated as “King of Beasts” instead
