This is not Johnny Sokko.
This live-action movie (or TV show) was about an hour long, likely produced in the late 80's/early 90's, and VERY low budget.
A Japanese boy and his giant multi-colored robot fight monsters. There was eerie Asian music throughout the video. I can't remember what the monsters looked like. If you can think of questions that might stir up additional memories, please feel free to ask. Any help is greatly appreciated, as this is driving me insane trying to figure out the name of the movie/show.
It was a humanoid robot. I believe it was a stunt guy in a suit, but I could be wrong. I can't remember the exact colors - just that it was multi-colored. I think it was a young boy, possibly a teenager. He directed the robot, but I think he just said the commands, not anything involving a controller. Thanks for the questions! Sorry I can't be more descriptive.
