There was a good Japanese anime turned into a TV movie, called ‘Casshan: Robot Hunter’. The gist is a well meaning scientist creates powerful robots to “protect” the Earth and ecologically restore it.
But the robots decide to “protect” the Earth by annihilating most of its people. So, just before he and his wife are killed by the robots, they turn their teenage son into a super android to destroy the robots.
The robots are ruled by the “black king robot”, who is Casshan’s final target, and also contains his late father’s conscious mind; whereas his mother’s mind has been put in a robotic swan.
Ironically, it is sort of an anti-environmentalist movie. But it moves at a good clip, with a lot of action, and at 1:20 in length it is just long enough.
Is the son named Kenny perchance?
