Ultra Men!

THE 6 ULTRA BROTHERS VS. THE MONSTER ARMY-1974-For some reason the sun has come dangerously close to the Earth causing droughts. Some kids dance around a temple praying for water. When robbers come to steal, one boy Koh tries to stop them and he's shot in the face and killed. While his friends mourn his death the 6 Ultramen and the mother of Ultra try to rectify his death by fusing Koh with the Hindu god Haruman. He's sent back to Earth to get the robbers and to fix the sun's rotation problem. He finds the robbers and crushes the trio then helps save Koh's friend's life. He also visits the god of the sun (?) and the sun moves away from the Earth. 

Unfortunately some scientists at a missile launching base screw up and destroy the whole facility and in the process release some gigantic monsters living under the Earth! Haruman takes them on and does pretty good until the four on one situation (a fifth monster terrorizes a woman and her kid) proves too much and Haruman is imprisoned in an energy sphere. But it's the 6 Ultra Brothers to the rescue. They free Haruman and beat down the bad boys. After 4 of the monsters are vanquished poor Gomora is left and used as a punching bag by the good guys until Haruman slices him in half! 

Wonderful cheesy effects in this epic that was co-produced and filmed in Thailand. It was the subject of much controversy for years. I apologize if I didn't  get  the whole plot correct (the copy I viewed had no subtitles).

Thanks for watching!
