Diego has the looks of a thug, or tough guy, but his personality betrays that. A rather fit boy that is of average height for his age at 5'9 and weighing an approximate 166 pounds. Diego has a light muscle tone on his body. No where near bodybuilder, but he looks like the time who does work. It widens his body a little bit. . Diego is a teenager that appears to be Hispanic, but isn't exactly. Because of an interracial relationship between his great-grandparents, he has Caucasian in his roots. But because their children primarily got married to Hispanic people, those Caucasian roots got rather overshadowed. To be exact, Diego is Mexican, Colombian, Dominican, Spanish, Greek, & French. One thing that has become a trait among his family is their large, pronounced, square noses with thick, nose bridges. The whole nose is triangle shaped from the side. I wouldn't say that it's their most attractive feature, but yeah. Diego has one of his own naturally. It looks disproportionate with the rest of his sharp facial features, and therefore, sticks out much more. In contrast to his thin, rather pokey, lips, medium sized ears that stick out somewhat, and small, squared (with a cleft), chin, and a sharp jawline, with a rather dull and unnoticeable jaw. All topped off with medium-sized amber eyes, that usually convey Diego's sense of regret, and more. One thing about Diego is that he doesn't do a good job at hiding his emotions. Usually his facial expression gives it away, but his overall body language also conveys his emotions. He constantly appears as if he's someone who always has a little something on his mind. His eyes are a little dark, which gives away that he doesn't sleep too often as well.

He has a head of straight deep-black hair, cut short, and styled into a choppy, messy, hairstyle. Along with a faint, growing, mustache on his upper-lip. But enough about the boy's face, time to describe his body. He's very thin, and doesn't have too much fat or muscles packed on him. However, he's kept thin from his physical activities such as playing basketball and running, so he doesn't so much as sits on his ass all day. Diego's skin is a off-white, somewhat tan, color, and is clear that he isn't exactly white if someone examines him. Like everyone, he has scars on his body, all of which have stories of their own. From scarred knuckles, to various knife wounds on his arms (From apparently small blades), and various other brutal scars. He doesn't like talking about them, and usually changes the subject. However, Diego has symbols and markings on his body that resemble tattoos. They aren't true tattoos, when he got his power, these markings appeared on his body. Starting at his wrists, he has a network of fire symbols that appear very similar to tribal tattoos that go up his body, and encompass his chest, and go down to his ankles. Whenever he activates his power, these symbols start glowing, and combust into flames. Just to keep people from getting suspicious about his body, he tells them that they're tattoos.
