**Stolas** from *Helluva Boss* is a tall, slender anthropomorphic owl demon of the Ars Goetia, with elegant gray-blue plumage that darkens on his head and long plume-like tail, a lighter chest puff, a white heart-shaped facial disc, a small black beak, and two pairs of almond-shaped red eyes. His long, thin black limbs end in owl-like talons, and he typically dresses in regal attire such as a deep red tunic with gold buttons, paired with a cape or coat that emphasizes his princely status. Beneath the outward image of a refined, ostentatious royal, Stolas is flamboyant, dramatic, eccentric, and often giddily emotional—quick to chase his interests (plants, stars, books, and romance) while sometimes overlooking others’ feelings. He is intelligent and soft-spoken with a formal, flowery manner, yet openly romantic, sensual, and unapologetically expressive.
