"The Incredible Hulk", starring Lou Ferrigno and Bill Bixby.
Very similar in formula to "Kung Fu".
A man wanders into town, gets a job, and meets people. At least one of the people is being victimized in some way. Soon, the man is being victimized, too. After a few rough encounters, the man suddenly becomes a fierce fighter who devastates and/or chases off the bad guys. The people are grateful, but the man can't stay because his presence could put the people's lives in even greater danger. Cue the sad, sappy closing theme music as the man wanders away.
I liked that show as a kid.
