Sieg (Fate) Rule 34

Sieg is a central character in the Fate franchise, initially appearing as a homunculus created for the Great Holy Grail War in Fate/Apocrypha. He gains self-awareness and escapes, later becoming the Master of Rider of Black and receiving the heart of the hero Siegfried, which allows him to transform into Siegfried and inherit his powers. In Fate/Grand Order, he appears as a summonable Servant. Visually, Sieg is known for his long blonde hair, striking eyes, and slender build, often depicted in his white and blue outfit or in various alternate costumes. His personality is earnest, compassionate, and determined, with a quiet strength that fan artists frequently highlight. In fan art, he is commonly shown alongside Jeanne d'Arc and Astolfo, reflecting his close bonds with them. Artists often focus on his gentle smile, dynamic combat poses, and the contrast between his homunculus origins and his heroic aspirations. His transformations and interactions with other characters are popular themes.
