Quincy Barrett (Patrick McKenna) is the father of Betty Barrett and spouse to Tanya Barrett. He resembles a slightly absent-minded, stereotypical 1950's salesman who is usually busy with whatever new gadget he is trying to sell, but he remains a devoted father when he's around. Unlike his wife, he lets Betty be herself and encourages her interest in space, comics, and movies; however, more like his wife, he tries to get Betty to do some things she isn't interested in. He and Tanya are unaware about Betty being a Galactic Guardian in order to protect them and because they may never understand.
- Patrick McKenna is better known for playing Harold Green on The Red Green Show. Both Quincy and Harold share similarities, including similar glasses.
