Walter is Arthur and Dot's step-father. Arthur thought his obsession with asking if people's feet were good was weird. At Walter's 60th birthday party, he was pleased that The Tick arrived. In episode 12, Walter states that he recognizes the sound of The Terror's T-Ship and shows exceptional martial arts skills. In the second season we learned that Walter is a retired AEGIS agent.
