Haredas

Haredas is an old man who lives in Weatheria. In the anime Haredas uses a technique in the form of a bubblelike 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 absentminded and bumbling. Source: One Piece Wikia
