Main characters

Smith family

• Stan Smith: Works for the CIA and is always on the alert for terrorist activity. He has a terror-alert color code on his fridge and occasionally shoots the toaster whenever toast pops-up.

• Francine Smith: Sweet and loving wife of Stan Smith, who keeps her own opinions and party-hearty personality mostly to herself for the sake of her husband's ultra-conservative views, although she isn't afraid to put him in his place.

• Hayley Smith: The ultra-liberal daughter of Stan and Francine. Because of her views, Stan at times distrusts her and puts her through security measures that you would find before entering the White House.

• Steve Smith: The geeky little brother of Hayley and son of Stan and Francine. He goes to extreme measures to raise his social status.

• Klaus the Talking Fish: The result of an experiment gone horribly wrong, where a German man's brain was transplanted into a goldfish. In love with Francine.

• Roger the Alien: The sarcastic space alien Stan rescued from Area 51. Spends his time eating smoking and drinking as he is unable to leave the house.
