In his first appearance, he wears a dark blue jacket with a high, ripped collar, and matching pants, cut off above his ankles, a pair of dark dress shoes on his feet. He also seems to be lacking earlobes on both sides of his ears upon closer inspection. He has several silver cartilage piercings in both ears, and a triple nostril piercing on the right side of his nose.
These appear to be attached to the rest of his skin by multiple, crude surgical staples or hoop piercings. His most striking features are undoubtedly the patches of gnarled, wrinkled, purple skin that cover much of his lower face and neck, all the way down past his collarbone, below his eyes, around his torso, and on his arms and legs due to him losing control of his fire Quirk at a young age and engulfing him in flames. Before the reveal of his true identity, his hair was dyed black. He has white hair with a few red streaks at its crown that spikes upward around his head, hanging low over his eyes, which are thin, turquoise in color, and heavily lidded. Dabi is a fairly tall, pale young man of a slim, somewhat lanky build, described to be in his early twenties.
