Kari Elizabeth Byron is the one and only female co-host of the show (after Scottie Chapman left), and the only one to take leave off of the show for more than one episode, due to her pregnancy. Her first appearance on the show was back in the show's pilot mini-season, in the episode Jet-Assisted Chevy.
Kari was the body model for the Vacuum Toilet myth.
Kari, as a vegetarian, does not eat meat. As such, she is often chosen to pick up meat for the myths that the rest of the Build Team tests.
