This was a fun movie, reminding me of GUYVER 2 (live action version) with over-the-top action and guys running around in rubber monster costumes. Although I haven't seen the first movie this one was easy to follow. The BLACK MASK character was created by this giant brain to be the ultimate assassin but he rebelled and became a hero, saving people instead of killing them. So the brain sends another super-man to dispose of him.In the meantime, though, another scientist has figured out a way to augment humans with animal DNA-and is using this group of pro-wrestlers as guinea pigs. He turns them into their namesakes, especially The Iguana, who transforms into this man/lizard and goes on a rampage.Lots of action, a cute female doctor with a peculiar phobia, cheesy monsters and lots more action. I think BLACK MASK is the INFRAMAN for the 21st century.
