From 25:15 to 35:10 we see a man and woman getting strapped to an electric table unable to free themselves. Also before they get strapped in apparently Galaxy King (the silver robot) really likes feeling thighs.
I know this movie has bootleg English subs as they were on Youtube a few years back, but this is all I can find, I could not even find a DDL or torrent. Better than nothing I guess. You have to feel bad for Riderman, he is the only hero who never outright defeats a monster.
