Idk if you can consider a halfway covered face a retcon, but this was probably before Oda 100% finalized the designs, but had a general idea as to what they should look like. Big Mom isn’t wearing her pirate hat here, while Kaido doesn’t seem to have a mustache, unless it’s being covered by Garp’s cape? How convenient…
I don’t know what’s next to his head though. Is that supposed to be the collar of a jacket, a cape or hair??
I like seeing early stuff like this. I want to see more!!
