In trailers of Soulcalibur: Lost Swords he wore armor almost identical to his Soulcalibur V counterpart, albeit with blue coloring, but in-game he starts off in his underwear. His hair is swept up with a couple bangs hanging down and his scar still remains. In Soulcalibur V, Siegfried's appearance begins to take on the traits of his father, and has grown a stubble. He continues to use this sword from Soulcalibur all the way to Soulcalibur III and resumes its use in Soulcalibur V.

His weapon in Soul Edge was originally Faust, a simple zweihander with a basic design, but swapped it for Requiem, a large blade with a flat end and a black lining in the center. He also gains a long blue scarf as well, completing the 'knight in shining armor' visage. As of Soulcalibur IV, his armor remains the same, but a second layer of crystalline armor covers with a rather intricate design and wields Soul Calibur instead of Requiem. In Soulcalibur III, he returns with armor bearing the motif of a phoenix as well as feathers on his pauldrons. During Soulcalibur he gains a long scar dashing over his right eye, which he likely gained fighting against Inferno in the original Soul Edge. Following his redemption, Soulcalibur and beyond, he retains the armor but his hair has grown longer, past shoulder length. In his debut, Siegfried appeared as a young German man with short blond hair and blue eyes, covered in simple knight armor. 3.8 Weapons introduced in Soulcalibur VI.3.7 Weapons introduced in Soulcalibur V.3.6 Weapons introduced in Soulcalibur: Broken Destiny.3.5 Weapons introduced in Soulcalibur IV.3.4 Weapons introduced in Soulcalibur Legends.3.3 Weapons introduced in Soulcalibur III.
