It's full title being Argoman the Fantastic Superman (1967) and its alternate US title, The Incredible Paris Incident.

So great. In the vein of the excellent Supersonic Man!

You can't get more riffworthy than a superhero whose catch phase is to tell his enemies to "unalive each other", like he's fresh off the YouTube comments.

This movie was made for riffing! The insane plot, the superhero who is as much of a criminal as the criminals he goes after, and the costumes, omg! So much unintentional silliness going on.

Italian superhero movies? Where the protagonist is the villain.

Okay, since you guys riffed on the Italian superhero classic, Superargo and the Faceless Giants (which is one of my favorite riffs.) I think now would be the time to bring up Argoman and riff that. A super hero in a weird white and yellow costume and a black cape with a Cyclops-style cowl with mental powers that convince his enemies to kill themselves. His main catch phrase is "Kill each other, kill each other." I mean what a super hero role model for all the kids in Italy. How grand! Anyway, that's my pitch. It would be a beyond awesome riff.
