Before he was sired, Lyle and his brother were murderers, known for their extreme brutality. After his brother's demise, he returned a year later with his wife Candy to participate in "SlayerFest '98", but after Candy was staked by Buffy, he was intimidated into departing Sunnydale by Cordelia, despite the fact that she was not a Slayer.
Lyle Gorch survived both encounters with Buffy because of his "fight or flight" personality.
