Wes Evans

Wes Evans (ウェス・エヴァンス, Wesu Evansu) is Soul's brother and was the first one to find out about Soul's weapon abilities. He is said to be a master at the violin. Soul feels that he can never be like his brother because he does not know what he is 'capable of'. In the manga, Wes and Soul look exactly alike except for the age difference and how Wes's hair is more tamed than Soul's. (Source: Soul Eater Wikia)
