One of my favorite ST:TNG episodes is “A Matter of Time” from season 5. In this episode, while the Enterprise crew is trying to save a planet from a global catastrophe, a time traveler from the future, Berlinghoff Rasmussen, arrives to observe. Picard and crew wrestle with the ethics of whether or not to use future knowledge to solve a present danger. And, spoiler, there’s a great twist in the end (are spoiler warnings necessary for something that aired 27 years ago?)
While the role was originally written for Robin Williams, it is delightfully played by Max Headroom actor Matt Frewer. His performance is just plain fun to watch as he intrigues, amuses, annoys, and frustrates (sometimes all at once) the Enterprise crew.
This figure was made from a Micro Force Hologram Luke Skywalker body and a Fighter Pod Chekov head. His coat is made from clay, and he is holding a stolen tricorder taken from a Fighter Pod McCoy.
