Description of Professor Utonium (The one who made them/the surrogate dad):

Professor Utonium is very "square", handsome, and old-fashioned. He wears a white lab coat with pens in its pocket and a shirt and tie. His head is impossibly rectangular with carefully parted black hair and thick eyebrows. He has blue eyes during one scene in "Mr. Mojo's Rising." The Professor's voice is very thoughtful, exactly the sort anyone might expect from an eminent scientist and/or a father figure in a 1950s TV series. In the earlier episodes (such as "Monkey See, Doggie Do"), he was seen carrying a tobacco pipe, but this was dropped in the later episodes.
