Even after all those years, Siegfried remains one of my favorite Sabers, despite Apocrypha doing him dirty. From a certain point of view, Grand Order added salt to the injury, but even then, his combo with George still can overcome powerful foes.
Coincidentally, I happen to really like characters in Japanese media named after the dragon slayer from the Nibelungenlied (which is one of my favorite medieval literature texts): apart from the Servant, Siegfried Schtauffen is in my Top 3 SoulCalibur mains (along with Nightmare and Raphaël Sorel) and Dubhe Siegfried is in my Top 3 favorite Asgard God Warriors (along with Megrez Alberich and Phecda Thor).
