Family Guy: 10 Best Characters Who Only Appeared In One Episode

While Glenn Quagmire might have found himself in a real pickle when he married Charmisse, nothing quite compared to the time he spent with his "perfect match," Sonja.

Every bit as promiscuous as the sex-crazed senior, Sonja quickly convinced him she was the one in "Quagmire's Quagmire." It wasn't before long, though, that viewers saw her true, wicked colors.

The sex between them was fun for the pilot at first, but his new lady friend began to overstep personal boundaries and beat him. He tried to alert Peter and the boys during a visit to The Drunken Clam, but as expected, they didn't take the hint right away. Because of this, Sonja ended up kidnapping their longtime friend outside of the bar.

Luckily, Quag's pals showed up just in time to stop Sonja from hurting him further. Although she was taken out of the picture, she still managed to get the last laugh when Quagmire's father, Ida, worried she was pregnant after the mad girlfriend forced them to have sex. Worse, unlike some of the other obscure characters, Sonja wasn't completely killed off, meaning she was eligible to come back later on.
