Dr. Peter Brady was a scientist much like the first ever invisible man, Dr. Jack Griffin. He too became invisible in a lab accident, though he decided to become a heroes for his country afterwards, keeping his sanity. He's a rather gentlemanly fellow, humble and intelligent. A brilliant man with a fairly strong moral compass, and capable of being rather kind and gentle. He is completely invisible, though the clothing he wears reveals his form. He's mostly an ordinary man aside from that.
