An inexperienced gangster is killed alongside his strong, respected boss and awakens to find a mad scientist has given him a new body made partly of his boss and partly of indestructible bionics.

This story, such as it is, has a Japanese dwarf scientist playing a modern-day Dr. Frankenstein (well, Dr. Frankenstein as the hunchback of Notre Dame, actually) in an attempt to find a way to prolong his dying sister's life. Yet, instead of going to the morgue, he goes out and finds associates, kills them in gruesome ways and then performs experiments on their various body parts.

Sequel to "Tetsuo" this time has the Iron Man transforming into cyberkinetic gun when a gang of vicious skinheads kidnap his son. When the skinheads capture him, they begin to experiment on him...speeding up the mutative process!

A strange man known only as the "metal fetishist", who seems to have an insane compulsion to stick scrap metal into his body, is hit and possibly killed by a Japanese "salaryman", out for a drive with his girlfriend. The salaryman then notices that he is being slowly overtaken by some kind of disease that is turning his body into scrap metal, and that his nemesis is not in fact dead but is somehow masterminding and guiding his rage and frustration-fueled transformation.
