Was there a character in Star Trek named Trulane. Would of been in the original series.?

I am trying to find a certain episode. I believe that most of the main crew is on a planet and somewhere Kirk and this being I believe to be named Trulane are hunting each other. Towards the end I believe the being's father tells him to stop. He was trying to have fun. That is all I really know. Have looked at sites and found nothing.
