Belos is revealed to be a haggard, middle-aged human with pale skin, a sharp jawline, and long, messy ash-blonde hair that falls past his shoulders. His most striking features are his cold, pale blue eyes and a massive, jagged scar that cuts horizontally across the bridge of his nose and cheeks. This scar is a rotting, mold-green color that occasionally glows with a sickening light, revealing the unstable magic warping his human flesh. His ears are normal and rounded, contrasting sharply with the pointed ears of the witches around him.He often wears his hair tied back into a loose ponytail, giving him a weary, rugged look that betrays his actual age of over 400 years. His expression is typically fixed in a patronizing, gentle smile that hides his deep malice, though it quickly shifts into a sneer of pure disgust when his authority is challenged. As his body decays further, green veins and patches of sludge skin begin to spread from his facial scar across his neck and hands. Belos is a masterful sociopath who weaponizes a calm, soft-spoken, and grandfatherly demeanor to manipulate entire populations. He presents himself as a benevolent savior who only wants to bring peace and order to the chaotic world. In reality, he is a fiercely arrogant, narcissistic, and cold-hearted zealot driven by a 400-year-old Puritanical hatred. He views the citizens of the Boiling Isles not as people, but as unholy pests that must be completely eradicated for the greater good of humanity.He possesses an absolute lack of empathy, viewing everyone around him merely as expendable tools. He ruthlessly murders his own allies, his loyal subjects, and even countless clones of his own brother without a shred of remorse or hesitation. He holds a massive superiority complex, genuinely believing he is a righteous hero who will be celebrated on Earth. Even when confronted with the horrific reality of his genocidal actions, his deep-seated delusion prevents him from ever experiencing guilt, blaming his victims for their own destruction until his very last breath.
