Kenner released Duke the Super Action Dog in 1974. This dog had lots of accessories and playsets and scaled well with most action figure of his time. His sets included electronic parts as well (light up devices). He is mistakenly identified by many as the Bionic Dog since he is in perfect scale with him. Movable legs, body and a jaw opening mouth.
Its a great toy. I got my Duke loose and had it painted to resemble Max the Bionic Dog from the Bionic Woman show.
Duke the Super Action Dog has been used by many as a stand in for Max the Bionic Dog from the Bionic woman TV show. I also used this figure with a custom paint job as part of my Custom Kenner Six Million Dollar Man Collection. https://www.facebook.com/CustomKennerSMDM/
