Weevil Edward

Edward Weevil, or "Whitebeard Jr.," is the self-proclaimed son of Edward Newgate and one of the Shichibukai. Unlike his self-proclaimed father, Weevil does not hold concepts of family in the same regard, believing that his alleged blood heritage is what makes him true family, not bonds built on friendship and camaraderie. Because of this, he violently attacked all those once affiliated with Whitebeard. (Source: One Piece Wiki)
