An Admiral in the navy and father of an autistic person himself, Sturgeon is initially very wary of the prospect of Minnow volunteering to work for the Navy and assumes she's being manipulated. He's aware of people who'd use her for insidious ends if given the chance and he's become very protective of people with conditions like hers.

He's the type of figure who appears imposing and has a strong voice but speaks rather softly and keeps other peoples' heads in the game. Think Michael Ironside's performances in Starship Troopers or Superman TAS.
