Hello everyone, and happy new year!
It's been a few weeks I'm desperately trying to remember a character I've seen somewhere in a public domain comic on this site, but I really couldn't get any help from the Google searches I've made.
He's a superhero, with a red costume (I can't remember if he wears a mask) and he has the ability to become intangible, almost like a ghost or an astral projection, when he uses a machine of his creation. Beware, this is probably a single appearance character, or at least he had very very limited appearances. He's from the early Golden Age, let's say from 1940 to 1942.
The image I have in mind is this character chasing after a train or something similar. I could swear I've seen this character somewhere, but I can't really recall his name nor Google has been of any help.
Thanks for the help!
