I cannot recall much of the movie... I can vaguely remember that there were two groups of five(?) fighting each other. One group are good guys, and are not human-shaped; the other group are bad guys, and are human-shaped. A character in the movie uses a large ring (that has nodes that burns? cannot remember clearly) as a weapon. Of the bad guys one is bald, dressing in black and using a green saber. The dialogue should be in English, so it might be an American movie, I guess... I remember having seen the movie when I was really very young.
