Haredas

Haredas is an old man who lives in Weatheria. In the anime, Haredas uses a technique in the form of a bubble-like barrier that allows him to be unfazed by the extreme weather while walking in Weatheria. Whether this is some new (or old) technique or possibly a type of technology native to the sky islands is unknown at this time. He has shown to have a rather carefree upbeat personality, smiling and seemingly enjoying himself mostly. He is also slightly absent-minded and bumbling. (Source: One Piece Wiki)
