Big Bob Pataki

Robert "Big Bob" Pataki (voiced by Maurice LaMarche) - Helga's ambitious entrepreneur father, a successful beeper salesman who owns a beeper store. He has extremely high expectations for Helga and frequently compares her to her older sister Olga. However, Bob does care for Helga and it is evidenced in subtle ways. In the Halloween episode when Helga and her classmates dress up as aliens and things take a turn for the worse when the people in there city think they're real aliens, Helga's friends run to the water tower that they made to look like a UFO. Meanwhile Bob and his friends go to the water tower and throw a grenade at the water tower thinking it's a UFO. Bob sees the "aliens" and gets a hold of Helga unbeknownst to him and shakes her. All the while she keeps saying "Dad! It's me, Helga!" Once the water leaks from the explosion and rinses away the facial paint, Bob realizes it really was Helga and not some alien trying to play a mind game. He says "I almost hurt my own kid! I'm a monster!" And gives her a hug as well as a piggy back ride down the hill. The episode where it is very evident that Bob does care for Helga is near the end of the episode "Quantity Time." Bob has difficulty showing his emotions for Helga since she and he always come into conflict with each other and clash. He often mistakenly calls Arnold "Alfred".
