Blitzo is a tall, lanky imp with red skin, a harlequin-like aesthetic, and a large heart-shaped skull symbol on his forehead. His right face, forearms, chest, and tail are marked with white burn scars. He has large curved black-and-white striped horns, black spines along his head and back, and a long tail. Despite his short stature—roughly four feet—he carries himself with explosive energy, always talking big and working to grow his startup assassination company. He is bombastic, sardonic, and utterly unprofessional, often disrespecting his employees while obsessing over his business's success. He isn't above manipulation, having slept with the married Stolas to gain an edge.
