One of the seven new God Warriors introduced in the series, and the fifth God Warrior to reveal himself. Sigmund is a brute warrior who dislikes cheap tricks in battle.
He is also the older brother of God Warrior Alpha Dubhe Siegfried, one of the God Warriors who fell in battle during the skirmish between Hilda and Athena. He distrusts Camus’ loyalty to the God Warriors, not caring whether he is a friend of Surt or not.
Sigmund carries a large greatsword called Gram.
Sigmund is the guardian of the chamber Niflheim, where he and Saga settle their score. Despite suffering the full effect of the Galaxian Explosion from Saga’s God Cloth, Sigmund is revealed to be still alive and sheds a tear as he watches Siegfried in the sky, smiling at him. Sigmund is also, in fact, the second who saw Hilda’s changed personality before being brought to prison by Thor and Syd (the Phecda and Mizar God Warriors from the original series respectively), the first being Alberich (The Megrez God Warrior from the original series)
