Episode cast overview:
Will Robinson (as Billy Mumy)
Penny Robinson (credit only)


Will and the robot come upon a dead "robotoid." Will wants a crack at fixing it while the robot wants it left alone or destroyed. In fact, something quite strange is happening with the Robinson's robot: he's developing beyond his programming, becoming more than just machine. Thanks to Will's repairs, the robotoid comes to life, but while it quickly presents itself as a subservient boon to the Robinsons, it secretly softens them up for capture by its distant alien masters, who are on their way.

LIS Robot Steals The Hour From Forbidden Planet Robot
13 February 2015 | by See all my reviews

A new Robot appears on the scene but it is un-clear if he is good or evil.

Some good moments in this adventure but it was more enjoyed in my youth. As much as I love the Forbidden Planet Robot it is actually the regular LIS Robot that totally steals this hour: in this episode we discover how important he is to LIS. We also discover that he has an almost human side that makes us love him.

In coming episodes of LIS we would get to know and love the Robot even more but War Of The Robots is a key hour because this is the first true TOUCHING Robot episode.
