Bionic Big Foot

An unforgettable image from my childhood was the moment (From the 1976 third season episode of the Six Million Dollar Man) when Steve Austin tore the arm off of Bigfoot. Not knowing that Big Foot was ALSO bionic, I thought for just a split second that Steve had ripped off Big Foot's actual flesh and blood arm! I freaked out for a moment.

Anyway. We all loved Big Foot in the 70's.
Whatever happened to him?
