appearance: light blue hair, and distinctive, often avian-inspired masks that obscure his face, reflecting his role as a "mad scientist". Because he creates "segments" of himself at different ages, his look can vary, but generally features a blend of formal, elegant attire and synthetic, medical-looking, or robotic components. He has pale skin, sharp red eyes, and long curly light blue hair. The Mask: The most iconic feature, Dottore wears a black and white mask. In his "Omega Build" (seen in Sumeru), this is a long, beak-shaped mask covering his eyes, evoking a 17th-century plague doctor or raven motif. Earring: A small, glowing blue earring is present on his right ear, which is a feature shared across his different, known segments. Attire: He wears a long white lab-coat-style coat over a blue dress shirt and cravat, often accompanied by black gloves with blue palms and loose, dark pants. His personality: Dottore is a cold, calculated, and deeply arrogant mad scientist, driven by an unyielding, unethical obsession with pushing human potential beyond its natural limits through "surpassing divinity". As a high-ranking Fatui Harbinger, he lacks any conventional moral compass, viewing humans -including children-as mere expendable "machines of a certain level of complexity" that can be modified, disassembled, or used as test subjects for his research. His personality is marked by extreme narcissism and a lack of empathy, often displaying apathy toward the severe suffering he causes, pursuing knowledge solely for personal curiosity and the satisfaction of his own ambition. Though brilliant and often creating multiple autonomous "segments" of himself at different ages to conduct simultaneous studies, he is despised by his colleagues for his monstrous actions and intense selfishness. Ultimately, Dottore sees himself as a superior, enlightened being, unfettered by mundane ethics, who is perfectly comfortable being a self-aware monster to achieve his scientific goals
