Super Inframan (1975)

What would you get if Ultraman was redone by in Hong Kong by the Shaw Brothers? You'd get Super Inframan of course!

When the evil Demon Princess breaks free from the center of the Earth where she had been imprisoned since the ice age, she immediately declares to the world her intention to conquer the Earth.

When she sends her demons and her army of Skeleton Men to attack the Science Headquarters (Yes, you read that right. It's a big metal dome with lots of blinking lights, exactly the kind of place you'd expect Kirk, Spock and McCoy to beam into along with an ill-fated red shirted ensign- in other words, it's a Science Headquarters), it falls to Rayma (played by Danny Lee) and the science patrol to stop them.

The Evil Demon Princess and her blond wig. 

Now the Science Patrol may be motorcycle riding kung fu experts dressed in silver jumpsuits that would make Evel Knievel jealous, but these monster are just too much for them to handle. That's when their boss, Professor Liu Ying De breaks out his secret weapon: he transforms Rayma into the kung fu cyborg superhero, Inframan. As Inframan, Rayma wastes no time battling the Demon Princess's minions, starting with the Plant Monster and the Spider Monster.

The Professor goes boating with Drill Mutant and a skeleton man.

For a while Inframan seems to have the demons on the run. That is until they steal Inframan's blue prints  and kidnap the Professor and his daughter in order to lure Inframan into a trap. Inframan and the Science patrol go the Demon Princess's lair for the final battle with her and her minions, but will they survive?

If you love Shaw Brothers movies and Superhero movies, find a copy of this movie and watch it.  This movie is pure fun and has surprisingly good special effects for a low budget movie from the mid 70s that looks like a power ranger episode.  If you need more convincing watch one of these clips:
