John Seal Brain (which is never described as Brain 17 at any time in this film) is the world's greatest computer, and also the most intelligent 'being' on Planet Earth. One day, Brain decides to abandon its terrestrial moorings, and it's up to The Defenders to track it down. Unfortunately, Brain has developed an amazing army of deadly giant robots (including one with a huge 17 emblazoned on its chest-plate) with which it plans to subjugate its creators. This mind-melting feature, apparently edited from a multi-episode Japanese television series, features some of the most endearingly inept special effects sequences you will ever see, as well as a plot that proceeds at breakneck pace, terrible dubbing, and narration by a man who sounds suspiciously like legendary voice-over artist Gary Owens. If you like Gigantor or Princess Dragon Mom, there's a place in your home video library for Brain 17. It's a humdinger of a doozy! Know what I mean?
