Sasquatch. This was the robot watchdog of some marooned aliens in the The Six Million Dollar Man. It also appeared in a crossover episode of The Bionic Woman. These aliens wanted "Bigfoot" to cause concern in the Pacific Northwest in order to protect their privacy. Needless to say, it did not work and Steve Austin was on the case. Eventually, Sasquatch and the bionic cohorts become close friends. Cybernetic friends stick together!
