Lotsa lil guys.
Mr Justice:
Like the Spectre or the Wraith (or Sergeant Spook or the Gay Ghost or the Ghost Patrol...), Mr Justice is your classic restless spirit who remains on Earth to mete out justice to the wicked. Specifically, Mr Justice is the 200 year old ghost of the fictional English Prince James, cruelly slain by followers of Prince Richard during the Rogers Rebellion of the 1740s. Astute readers and students of history might have noticed a few things about the preceding sentence that all boil down to the fact that the 1740s were actually recent enough that we know a whole lot about what was going on then, including that people weren't running around in Medieval armour even if they were sometimes still using swords and shields during the Jacobite Rebellion of 1745. Also, this is what the crown prince of England looked like in 1741. (they change it to the 11th Century later on, because that makes a lot more sense).
Prince James' ghost is tethered to the place of his death per the usual ghost rules but he manages to get around that in a fairly unprecedented way: due the the war, the British government decides to move the castle to America and it is sunk by the Nazis on the way there. And since a pile of stone on the bottom of the Atlantic is not a castle, James is free to go become Mr Justice, the ghost super-hero frequently compared to the Spectre but who doesn't really get up to the sames sort of divine judgment stuff. He does fight the Devil/Satan a lot, though.
Possibly my favourite thing about Mr Justice is the fact that his secret identity is a fellow named Mr Justice and nobody really calls any attention to that fact. Mr Justice (secret identity of Mr Justice) is attached to the office of Mayor Clark (city unnamed but very NYC-esque) as a sort of troubleshooter. He kind of has a love interest in mayor's daughter Pat Clark and a rival in District Attorney Roy Winkler, above, but neither is explored very thoroughly. (Blue Ribbon Comics 009, 1941)
Inferno:
Above is an abridged account of Inferno's time as a super-villain, which we will treat separately because... well, because when you're reading a lot of old comics in a somewhat systematic manner you have to have some sort of organizational method and I chose alphabetical by year, and Inferno's time on the lists of crime happened in Zip Comics. I simply haven't gotten there yet. Suffice to say that he was a crook who changed his ways due to the influence of Steel Sterling and opted to do his time.
Despite his best efforts, Inferno is compelled to break jail to stop a group of prison escapees from murdering a judge and then is encouraged by that same judge to go on the lam because the authorities are going to try to murder Inferno. It's a real reciprocal life-saving situation! Although I am tempted to think that that judge could possibly have just called someone and arranged for a stay of summary execution for Inferno.
The rest of Inferno's career as a Golden Age super-hero is kind of a fun twist on the old trope of the super-hero that everyone thinks is a crook, in that he doesn't really have a secret identity per se so just travels around doing itinerant labour until he sees a crime go and changes outfits. The idea of this hobo existence kind of goes by the wayside after a couple of issues when Secret Service Agent Virginia Ames enters the picture, as Inferno's stories were on the shorter side and just didn't have the real estate for both a love interest and workplace drama.
Inferno only managed seven adventures before trotting off to limbo to wait for Archie's 1960s super-hero revival but don't worry! He got a full pardon in his last adventure so the other heroes won't be hassling him. (Blue Ribbon Comics 013, 1941)
Captain Flag:
On the one hand, Captain Flag is a regular-style patriotic hero but on a different, more entertaining hand he is a patriotic hero with a very fun origin. To whit: one day super-villain the Black Hand is attempting to wrest scientific secrets from inventor John Townsend when his playboy son Tom stumbles in half lit. The Black Hand is about to dispose of Tom using his horrible hand when a huge eagle just kind of... flaps into the room and ends up leaving with Tom Townsend in its talons.
Thus saved, Tom just kind of lives with the eagle for a while and transforms from a dissipated youth to a lean, athletic man full of fish protein. And then the eagle comes back one day with an American flag! It's a veritable sign from the heavens it what it is!
And so, Tom Townsend becomes Captain Flag, who mostly fights the Black Hand. Which makes sense. Something else that would make a lot of sense: adding a belt to that costume. (Blue Ribbon Comics 016, 1941)
The Red Mask:
The Red Mask is very minor indeed! He appeared in four issues of Best Comics from Better Publications, of which only issue 2 appears to be available, which in turn was reprinting newspaper strips, of which only a handful are available.
What we have on the guy is this: he leads a tribe on the island of Kaukura, which is probably but not definitely in Oceania somewhere. Kaukura is chockablock with things like sacred grottoes, immortal monsters and hostile tribes and the Red Mask has assigned himself the task of protecting a bunch of clueless outsiders like Nina and Danny here who have blundered in looking for their friend and found themselves up to their neck in trouble.
The most interesting thing about the Red Mask is that he is by a fair margin the first nonwhite super-hero, though thanks to colouring limitations and some inexact geography it's a bit difficult to get more exact than that. (Best Comics 002, 1939)
