Masked Avengers (1981)
Somewhat in the style of FIVE VENOMS, with a 'who is good, who is bad?' theme that would be interesting if every revelation wasn't foreshadowed so blatantly. The plot doesn't make an awful lot of sense, so don't think too deeply on it. Chin Siu-Ho gets a substantial role, though Kuo Chui's character is the only one that's at all interesting.
Of course the action is the highlight in most Venoms films, and so too here - the trident work is especially interesting.
