Gilgamesh is opportunistic and seeks to gain wealth and fame by unscrupulous means, including stealing, extortion, scamming and treasure hunting. He plays Tetra Master and kindly introduces others into the art, having amassed a rare deck of airship cards himself. He is depicted more as a nuisance than a serious criminal, and quite cowardly as he is easily frightened off by the idea of being opposed by someone stronger than him. He portrays himself as an expert treasure hunter, but in truth Gilgamesh is closer to a novice.
