At 5'7" David Perez is a bit short, and at 120 lbs he is thin for his height. He walks with a slight limp and sometimes uses a cane. His dark brown hair is neatly cut.

He is generally sharply attired and even when dressed casually he always seems neat and well groomed. Despite growing up in New York he has a neutral accent, if anything there is a slight hint of something foreign about it.
