As his sister Gutrune, he has a bad reputation: coward, hypocrite, vain, interested, fearful etc. That is a lot for a man obsessed by his image. He is the typical politician preoccupied by his local reputation and the society man worried about his public image.

As a consequence, his line of song is of the most melodious of the Ring, round, warm and noble as an electoral speech. The friendship declarations in the Ring sound nicely, but the theme, which accompanies them is taken from Mime's ceremonial reverences when he reveals his intention to murder Siegfried. Gunther is also a cyclothymic as many weak ones. He passes from bad humor to enthusiasm, and as long as his appearances are kept, he is capable of treason. Gunther is dominated by his half brother Hagen; he is in fact afraid of him so that he flatters him to disarm his jealousy.
