I am Iron Man - Tetsuo, probably

Watched for Hooptober Se7en, film 17/33. It takes a real singular vision to make a good, erotic(?), cyberpunk epic on a shoe-string with a scrapyard's worth of junk, that's for sure.

Fun fact: The name of this character is translated to "Metal Fetishist" in English subtitles, but in the original Japanese credits is listed only as "yatsu", which translates to "guy" (wikipedia)
