This painting depicts the Thunder God, who carries a mallet and a drum that he used to produce the sounds of thunder. The presentation of the deity standing with his mouth wide open while holding a sword with one leg outstretched appears to be capturing the moment of his descent from the heavens to punish evil people. During the Joseon dynasty, the Thunder God was commonly illustrated as one of the many deities in Buddhist paintings. An individual image of the Thunder God like this is unusual. Kim Deokseong was known to be particularly proficient at painting Buddhist guardian deities. The masculine body and thick body hair of the Thunder God amplify the dynamic atmosphere. The shading in the muscles indicates the adoption of Western-style painting techniques in the late Joseon period.
