None of these guys are ever going to be in a movie.
It's been a while since we've seen any masked cowboys, so here's a particularly well-dressed bunch about to have a scrap with the Rio Kid. He doesn't get the upper hand in this particular encounter, but by gum he eventually brings rancher John Wendel and his whole gang of rustlers to justice. (Thrilling Comics 002, 1940)
Likewise, it's been a while since we've seen a masked Nazi spy, and even though we only get one panel of X-5 aka Captain Clarke here, he fits the bill as he arranges to frame Tom Niles, the Undersea Raider, for espionage. (Thrilling Comics 006, 1940)
This completely unnamed masked killer is actually Violet Parsons, who has an especially poor reaction to being cut out of her father's will: she murders her brothers Frank and Henry and tries to pin the killings on her insane brother Robert. She is ultimately undone by the fact that a person, even one who has had a nervous breakdown, won't automatically turn into a ravening beast man if you lock them in a room until they grow a long beard. The Woman in Red triumphs once more. (Thrilling Comics 008, 1940)
Someone has been murdering everyone who stays in the De Luxe Suite of the Hotel Metropolis, and the Woman in Red is on the case. The murderer turns out to be Mr Bascom, the hotel manager who used to be the hotel's owner, who couldn't stand to see the hotel's new owner make a success out of a business he failed at. He only shows up in this mask for a few panels, but I would like to point out it's unusual length, required so as to cover up Bascom's mustache. (Thrilling Comics 009, 1940)
