First Appearance: Sure-Fire Comics #3 (Ace)

Marvo 1.2 Go+. Ronald Byrd, who I'm in awe of, gives us this:

Lastly, it's back to the future for the adventures of Marvo 1.2 Go+. I suppose that's pronounced "mar vo one point two go plus," but who knows?  In the year 2680 (nice random number), Marvo is the son of one of the world's greatest scientists.  Although only 15, Marvo has inherited his father's intelligence (literally, it would seem, since it is claimed he has the knowledge of "an average scientist of 40" (oh, wait, then it couldn't be Dad, since he's above "average"); sounds like a somewhat backhanded compliment, but hey, I couldn't even pass for a below-average scientist of 40).  The "+" at the end of Marvo's name (which he wears emblazoned on his future-tunic) is a status symbol, heretofore awarded only to adult men (and only ten of them), which allows him to use the "super-hypnobioscope" (never use one prefix when three will do, I suppose; technology with a lot of syllables? why, this must be THE FUTURE) to learn while he sleeps.  In #3 (boy, Jovians, Atlantis, condors flying into planes, and now this, Superworld #3 just about had it ALL, I guess), Marvo flies (a ship, presumably) to intercept a traveling planet on collision course with Earth (there were a LOT of those in the golden age, we're just lucky that by the 1960s they were only coming in SHIPS); although dead on the surface, the planet's interior is inhabited by, no, not creamy nougat, but by the Antarenes, or the Antmen of Antar.  The Antarenes have fled their dead sun (evidently there wasn't time to build a fleet or anything, so they just took the entire planet) in search of a new one; needless to say, Marvo sees to it that their plan to bump Earth out of orbit and take its place comes to naught.

Masked Marvel (II). Ronald Byrd, Defender Of Liberty, adds this:

Chet Fairchild was the son of oil millionaire Colonel Carlton Fairchild, brother to the beautiful Marion, and an apparent graduate of the Don Diego Vega school of behavior (later known as the Bruce Wayne Finishing School). However, Chet led a double life as the Masked Marvel, whose caped costume included a green mask that literally made the Marvel look like he had a skull for a head. The fact that his name was, of course, the MASKED Marvel indicates that he wasn't making any concerted effort to persuade people that he was a supernatural being of some sort and was just going for shock value (precisely what they would have made such a realistic-looking mask out of in the 1800s is open to debate). Although, as noted, his spooky appearance was strictly for show, the Masked Marvel encountered both mundane and supernatural threats.

Micro Face. Tom Woods loses his brother to gangsters' guns. He swears revenge and puts together a costume to do so. (He beats the gangsters, of course) He has no superpowers, but his mask has a microphone for amplifying his voice, a hearing-amplifier, and "photoelectric lenses" for x-ray vision. As a welcome supplement, here's Ronald Byrd's comments on Microface:

Micro-Face, Tom Woods, has his own set of artificial powers via a high-tech mask that enables him to amplify or throw his voice (hence "Micro-Face" ala "microphone"), as well as granting him super-hearing and x-ray vision. Oddly, perhaps because of the comparatively esoteric nature of his powers, Micro-Face is the only Clue hero who restricts his activities to mundane organized crime, with nary a super-powered or even odd-looking enemy to his name (Have you noticed that, by and large, golden age super-heroes were ordinary-looking people in bizarre clothes, while the super-villains were bizarre-looking people in ordinary clothes?).  Although the existence of the super-hero Micro-Face IS known, he somehow manages to get repeated mileage out of the throw-your-voice trick, proving that criminals just aren't that bright, in addition to being a superstitious, cowa...oops, wrong guy.

Miss Fury. Socialite Marla Drake was left a costume (which, Ronald Byrd notes, she doesn't even wear in some stories) by her uncle. The costume was made of actual black leopard skin, and had originally been the ceremonial robe and symbol of justice of a "witch doctor." The robe didn't seem to grant her any extraordinary powers--besides her athleticism and fighting ability she had none--but the strip explicitly states that the robe is "cursed" with "strange powers" and can actually work "miracles." The skin may have been African, but a Brazilian character named "Albino Joe" (he's a Harvard-educated albino Native Brazilian) (no, really!) knows about the leopard skin, so perhaps Miss Fury's costume originally comes from Brazil.

Mitey Powers. The ever-informative Ronald Byrd contributes this:

First up is Mitey Powers, in appearance basically a typical spaceman in one of those jumpsuits with the round transparent helmet.  For openers, his problem is that Earth is being bombarded by mysterious forces which turn out to be Martians located in a base on the Moon (Maybe you've seen a classic old science fiction drawing of aliens with enormous chests, spatulate feet, big ears, and antennae, intended to demonstrate how life might adapt to conditions on another planet; that's them, at least according to the cover). Mitey (a name which is, I guess, only a little less likely than "Flash" or "Buck") builds his own ship (the Nina, named after his girlfriend) to reach the Moon and expose the Martians, later leading a space armada from Earth (so I guess we're in the future, then; up to this point the article didn't make it clear).  In #2, the Martians depose their warmongering leaders, and Mitey exposes a subsequent plot by those leaders.  Later still, both Earth and Mars are attacked by the Super Giants of Jupiter (about a thousand feet tall (that's pretty super and pretty giant, all right), these Jovians are somewhat reminiscent of Segar's Goons with long-whiskered catfish heads).  Mitey decimates the Jovians with poisonous Martian gnats (hey, don't look at ME), making him one of the hopefully few golden age heroes who decided that genocide was the correct way to solve a problem.  Mitey has a crew of secondary characters, but their names aren't mentioned.

Monako. Surprisingly similar to Mandrake the Magician (but that must be a coincidence, surely), Monako fights criminals and spies in full tuxedo and tophat, and is aided by Pere, a superstrong aide. Unlike Mandrake, however, Monako has actual magic to fall back upon, not just stage legerdemain and hypnosis. He also has an origin. Monako is the son of a missionary couple who were proseltyzing in India. When Monako was a young child his family was attacked by a tribe. This tribe practiced "black magic" and worshiped "many gods," and their attack wiped out Monako's family and the entire village he was living in, leaving Monako as the only survivor of the attack. The chief of the attacking tribe then raises Monako as his own son. Monako grows up, spending his teen years among the magicians of the tribe and learning their tricks. Unfortunately for him, he's away from the village when colonial soldiers slaughter the tribe, killing everyone. (In case you're keeping track at home, that's two families Monako has lost) Monako then emigrates to England, where he is formally educated, and then returns to India. He lives there for "quite some time" and begins to correct some of the injustices caused by his adoptive tribe. Then, later, he either moves to America or simply buys a house/opens an office there. He still spends time traveling, however, and in at least one story fights against a "student of the black arts."
