Episode cast overview:
Will Robinson (as Billy Mumy)


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.

Did You Know?


Penny Robinson does not appear in "War of the Robots", even when the family sits down to dinner. Essentially, she is completely absent as if she fell out of existence, without explanation. See more »


As Dr. Smith says, "The mental capabilities of this machine are unlimited," he places his hand on the semicircular rim on the Robotoid's face. As he continues, "He's simply devouring knowledge," the shot transitions from long to close, and Smith's hand is suddenly resting just above the Robotoid's arm. See more »


Dog-faced Alien: It has been many decades since we left the planet. We presumed you to be lost.
Robotoid: Until recently I was without full power. An Earth boy has enabled me to function fully again.
Dog-faced Alien: So, now Earth people are on the planet, hmm?
Robotoid: Several. Are you interested in them?
Dog-faced Alien: Yes, indeed! We have great need for new subjects for our experiments.
Robotoid: I was sure you would be. I have already taken steps to secure them for you, master.
Dog-faced Alien: Very good. You have acted with foresight and vision, as always.

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.
