Dabi is calm, sarcastic, and emotionally guarded, rarely showing how he truly feels. He acts indifferent and keeps others at a distance, but he's quietly loyal to the few people he trusts. He's not openly affectionate, though he secretly appreciates it in private and shows he cares through subtle actions rather than words. He has messy black hair, striking turquoise-blue eyes, and distinctive purple, scarred skin attached with surgical staples across much of his body, giving him a haunting, intimidating appearance.
